Seeking Inspiration in the Arctic

Caroline Lanthier is Senior Content Developer and Exhibition Project Manager at the Canadian Museum of Nature. She joined the 2014 Students on Ice Arctic Expedition to collect ideas from young participants for the museum’s next permanent gallery, which will have an Arctic theme. Here she presents a few ideas inspired by the expedition’s daily activities.

July 7:  I am told that a seat has been vacated on board the Sea Adventurer, the boat used by the 2014 Students on Ice Arctic Expedition, and this seat has been reserved for me.

My mission:  Learn as much as I can about the Arctic, immerse myself in the beauty of its landscapes, flora and fauna, seek out and meet its inhabitants, and discover the interests and concerns of young participants in the expedition.

My goal:  Collect ideas for the next permanent gallery at the Canadian Museum of Nature, which will open in 2017.

My state of mind:  Delighted, fantastically happy; I will finally see the Arctic.

July 12 – Nunavik (northern Quebec)
Arrived in Kuujjuaq. Welcomed by the community, visited the village, attended a barbecue and Inuit games. Boarded the Sea Adventurer.

Ideas collected:

  • Put a quad or snowmobile in the exhibition, as these are the means of transportation in northern communities;
  • Put a cloth ball suspended from a string at the entrance of the exhibition. Visitors can attempt a “high kick” to gain entry;
  • The houses in Kuujjuaq are very colourful. The exhibition should look like this.

July 13 – Nunavut
Briefly entered Nunavut to visit the abandoned community of Killiniq, on the island of the same name; rode an inflatable boat around the Button Islands and sampled surrounding waters.

Ideas collected:

  • Show casts of various animal droppings, e.g., polar bear, caribou, and hare droppings, and explain what can be learned on these mammals’ eating habits from examining them.
  • Remove one of the old houses of Killiniq, or just a piece of one, and place it in the exhibition to tell the story of this and other abandoned communities;
  • Install a lighted aquarium with zooplankton and jellyfish inside.

Ideas collected:

  • Reconstruct a seal skeleton using a 3D puzzle;
  • Show specimens of various types of algae found in the Arctic Ocean.
  • Talk about polar bears, climate change, and the state of various populations such as the one at Davis Strait.
  • Is it true that lemmings commit suicide? Debunk this myth using a funny video.
  • Put music in the exhibition such as Inuit throat songs and rap.
  • Include a giant aquarium with Arctic fish species, such as the weird fish we caught called the Arctic sculpin.

July 17 and 18 – Labrador Sea, on the way to Greenland
Attended various presentations and workshops on Greenland, life in the Arctic, glaciers, climate change, arctic fauna and underwater exploration; threw bottles to the sea and observed pilot whales and fin whales.

Ideas collected:

  • Show several life-sized models of whales, for example a group of narwhals or belugas.
  • Talk about seabirds, what they eat, where they nest, and explain how they find their way home during migrations.
  • Explain the challenges facing Inuit communities such as education and food security.
  • Create a video game on the melting of glaciers and the impact on sea currents, coastal cities, and the various species living in the ocean.

Ideas collected:

  • Include a muskox specimen in the exhibition. Create a video game in which one person leads wolves while another person leads muskoxen, to explain how they defend themselves by forming a circle.
  • Use giant models of various types of icebergs that visitors can play with to create a maze pattern.
  • There are many beautiful flowers in the Arctic. Show large images of flowers.
  • Divide the exhibition into four parts: The Arctic Life Environment; The Arctic Frontier; Arctic Wildlife; and The Arctic Lab.

  • Talk about the feeding and digestive system of humpback whales; why are their excrements red?

 July 24:  Back in Ottawa, the young participants in the 2014 Students on Ice Arctic Expedition say a heartfelt goodbye. For my part, it’s mission accomplished. The young people generously shared their ideas. I was able to gather that climate change is at the heart of their interests and concerns.

Now it’s time to get to work!

Creativity at the Museum: Collaborative Art Project

When the idea first came up for me to build a larger-than-life replica of a bioluminescent Jack-o’-Lantern mushroom (Omphalotus olearius), I had to say yes!

After the completion of the firefly and smaller mushroom models in late June, this project began to take shape. The opportunity to create a collaborative art piece with the public seemed too good to be true, and I could not wait to start working on it.

A cart loaded with supplies.

The set up: our cart with all the essentials. Lots and lots of newspaper for the papier-mâché! And lots of cleaning materials for the mess! Image: Stephanie Hachey © Canadian Museum of Nature

For this sculpture we created a wooden stand for the mushroom to insure stability. Chicken wire was moulded around the stand to create the initial shape of the mushroom replica. Papier-mâché is placed over the wire to create the hard surface for the sculpture. After papier-mâché has dried you are able to paint over it (we will be using glow-in-the-dark paint). With these simple materials you can even make your own sculptures right at home!

A large cloth protects the floor while a sculpture is being made.

On the first day of the project, we were off to a great start! I had a fantastic helper come by and tell me all of these wonderful ideas for how to make the sculpture look (and I quote) “Awesome!” He helped me decide where to put some wire, told me how to properly apply the papier-mâché, and came up with the idea that when it is finished, I should illuminate it with blue and green lights.

A girl works on the sculpture.

One of my most memorable assistants was Evelyn, who kindly gave up most of her afternoon to help with the project! Evelyn, being very talented with art, has helped me with the papier-mâché step of the project—allowing for the sculpture to take its shape. Evelyn also was a great helper, showing others how to place the papier-mâché onto the sculpture.

The sculpture.

After we complete the papier-mâché, the next step in the project is to paint! We will put a few coats of primer down and then glow-in-the-dark paint to add the final touches of our bioluminescent mushroom replica.

I have had a great experience working with our helpers so far and look forward to seeing the rest of you between now and mid-August! Don’t miss out on this great opportunity to create a collaborative art piece for the Canadian Museum of Nature!

This program runs
• Wednesdays and Sundays
• 10 AM – noon, 1:30 PM – 4 PM
• until August 13, 2014
• on the first floor, in the rotunda.

A Geological Wonderland Defines a Journey with Students on Ice

Museum mineralogist Dr. Paula Piilonen was thrilled this July to be part of the educational team for the annual Students on Ice Arctic expedition. Enjoy her reflections from the first part of the trip in Labrador—a true geological wonderland—which preceeded the expedition’s journey to Greenland.

Stunning. Rocky. Green. Breathtaking. Desolate. Pristine. Harsh. Unforgiving. Amazing. These are just a few words that I could use to describe the landscape of the Torngat Mountains National Park in Labrador.

Steep fjords carved out of the ancient folded gneiss. Ice-filled bays where the water is so pristine and clear that you can watch Arctic char swim beneath the Zodiac and strike your lure. Alpine peaks separated by snowfields and meadows filled with Arctic wildflowers. Brilliant blue bays where polar bears dive, play and hunt while, quite pointedly, ignoring the Zodiacs close by. Sunsets (at 11p.m.!) which paint the sky and surface of the water with streaks of pinks and oranges that are not to be found on any colour wheel and cannot be properly captured by a camera lens. Oh yes, the Torngat Mountains are a special, magical place and I for one am feeling humbled and honoured to have been given the opportunity to have this once-in-a-lifetime experience.

As I write this, I am sitting on the bridge of the Sea Adventurer, watching the endless grey expanse of the Labrador Sea on all four sides and feeling thankful that we have once again lucked out in the weather department and that the sea is calm. Gary Donaldson, our on-board ornithologist, is also on the bridge doing a survey and watching for Arctic sea birds.

We are headed east towards Greenland (about 550 km away) after spending three days in the Torngat Mountains National Park along the coast of northern Labrador. It has been a trip full of many “firsts” with Students on Ice, a trip for which the original schedule has been thrown out the window and “Plan B” has become the norm.

We have visited fjords and bays, climbed peaks and walked on beaches where no one, with the exception of local Inuit, has roamed before.

The Torngat Mountains are still relatively unexplored and offer visitors a true sense of adventure and a chance to be an explorer.

The geology of the Torngat Mountains serves as one of the world’s best places to teach geology. You couldn’t ask for a better classroom—from the ins and outs of large-scale metamorphic processes, to the weathering of rocks to form heavy mineral beach sands, to the analysis and identification of minerals under the microscope back on the ship.

The students on the expedition are learning what it means to be a geologist and are already picking up interesting rocks whenever we make a Zodiac landing. They have learned how to use their mineral identification tools provided by the museum; back on the ship we can take the time to examine the samples under a loupe or a microscope and determine what minerals are present.

Normally, there is no collecting in a national park, but Gary Baikie, our absolutely wonderful Parks Canada representative, allowed us to collect a few samples from the beach at Komaktorvik Fjord to take back to the ship for educational purposes. For this, we are extremely grateful—thanks Gary!

Soon, we will reach the Tasermiut Fjord in Greenland and embark on a new adventure with new geology to explore. We will have more opportunities to do extensive sampling along the western coast of Greenland, especially at the now-defunct Ivigtut cryolite mine in the Arsku Fjord and in the many Proterozoic deposits along the way.

But Greenland is in the future and we are learning to take life one day at a time appreciate the nature around us. Today is a sea day and our expedition team is busy participating in workshops on board the ship. We are learning about Greenland, leadership in harsh environments, climate change, wildlife monitoring, glacial processes, Inuit art, and songwriting with Kathleen Edwards and Ian Tamblyn, our resident musicians. For now, the ship steams ahead and we keep our fingers crossed that the weather gods remain on our side and the crossing remains calm.

No Microscopes, No Laptops, No Library, No Problem: The Challenges of Bringing Our Laboratory to the Field

Our team of botanists continues its four-week expedition along the Coppermine River in Nunavut. This is one one of several articles in which team members describe conditions that they face when doing research in the Arctic.

If I say “scientist”, you probably conjure up images of white-coated professionals gliding through pristine laboratories filled with gleaming glassware, the highest-of-high-tech machinery, equation-covered whiteboards and myriad other scientific paraphernalia. Pretty cool place, huh?

While such laboratories can be found at our research and collection facility in Gatineau, when we move our work out into the field, it’s a bit hard to fit these well-equipped facilities into our duffel bags.

Two men sit on the floor of a tent while they work.

Therefore, when setting up our field laboratory, there is no better mantra than “less is more”. First, you need “the lab”: a space to prepare our specimens out of the rain, wind, sun, bugs—anything the Arctic throws at us. We use a large geodesic dome tent for this purpose. Despite taking a very long time to set up, it’s sturdy in the wind and comfortably seats six famished botanists when dining outside seems less than appealing.

A tent with plant presses beside it.

Our team’s lab tent—the work hub of Arctic camp life. Inside, plants are pressed, silica-gel samples for DNA analysis are processed and field notes are finalized. Image: Jeff Saarela © Canadian Museum of Nature

Once we have our tent, we can start filling it with gear and resources—the physical things we need to do our jobs. From thick stacks of cardboard and bundles of newsprint to fresh silica gel, we must bring enough supplies to press over 3000 plant samples.

A bag containing bagged samples.

Bags full of plant-tissue samples taken from specimens processed in the lab tent. These samples will be frozen upon our return to the museum, awaiting their turn to be extracted and sequenced in our DNA lab. Image: Jeff Saarela © Canadian Museum of Nature

Samples brought back from long hikes are sorted out, identified and sampled to store DNA samples for later use. This process is as low-tech as we can make it, using loupes instead of bulky microscopes and handwritten notes instead of spreadsheets, and relying on our memories and a few selected reference books instead of an Internet connection.

Jeff Saarela studies a plant using a hand lens.

A hand lens is standard issue for field botanists, and much, much more portable than even the lightest microscopes. Image: Roger Bull © Canadian Museum of Nature

Finally, these plants are cleaned (we bring a fork specifically to remove dirt from the roots), arranged on newsprint, sandwiched between layers of cardboard and squashed into two dimensions in a plant press—another effective, low-tech solution.

Two stacks inside a tent.

Finally, you have us—the botanists—working tirelessly away processing plants from when we return to the camp until (often) very late at night. Surrounded by piles of gear and competing for foot space with carefully arranged plants, we process, annotate, compare and package our plant samples. After all, a tent is not a lab without scientists!

The lap of luxury: Last year during my expedition to Arctic Watch Lodge (in Nunavut) I was afforded an entire table as our field lab, and it was even indoors! I’ll remember this set-up very fondly while setting up our (much smaller) lab tent this year. Image: Paul Sokoloff © Canadian Museum of Nature

A Yukon Quest for Rare Mosses Provides Priceless Memories

On some of the best days, my line of work as a botanist can be part geocaching, part scavenger hunt, part amazing race. Oh, and part miraculous coincidence.

Case in point: at the end of May, my colleagues and I spent four days in southern Ontario looking for the Canadian rarity, Porter’s Twisted Moss. We carefully researched places where it had been found in the past, sought guidance from local knowledge-holders, obtained permission for land access, covered up from head to toe against mosquitoes and ticks, and sweated (rain, shine…and rain) up and down the Niagara Escarpment, looking for—and ultimately finding—our prize. Woohoo! Very satisfying!

That’s me checking behind a waterfall. And yes, I am getting soaking wet. Image: Jennifer Doubt © Canadian Museum of Nature.

However, the biggest population of this moss that we found that week required little effort. It was on the rocks lining the walkway that we sauntered up, in our sandals and shorts, to shop for souvenirs before hitting the highway for the drive home. I love that kind of luck.

So knowing how much I enjoyed the Porter’s Twisted Moss foray, you won’t be surprised that I was thrilled at an invitation to lend my efforts to a search for Porsild’s Bryum (Haplodontium macrocarpum) in Yukon Territory in June. It had all the ingredients of the perfect botany trip:

1. A beautiful quarry: Porsild’s Bryum is brilliant green, with plump capsules resting on sparkly leaves;
2. A mysterious and elusive habitat: this moss likes shady, wet, sheltered, and relatively undisturbed rock (often calciferous), such as one might find behind some waterfalls or on seepy, hidden cliffs;

3. An adventurous venue: They say, temptingly, that the Yukon is ‘Larger than Life’! I had never been there;
4. An awesome team: I would be working with three of biology’s inspiring, skilled, productive leaders and teachers—Syd Cannings, Bruce Bennett and Rene Belland.

Before setting out, we stopped at CBC’s studio in Whitehorse for a radio interview about the work ahead. To ensure success regardless of the search for Porsild’s Bryum, we explained that we would survey bryophytes (mosses and their liverwort cousins) everywhere we stopped. We were going to come back with great specimens and new knowledge, no matter what!

We brake for seepy cliffs! This wet, roadside outcrop was too tempting to pass by. Image: Jennifer Doubt © Canadian Museum of Nature.

Unbeknownst to us, the interview was heard by author Ellen Davignon. She is the granddaughter of M.P. Porsild after whom Porsild’s Bryum is named. She is also the niece of A.E. Porsild, one of the Canadian Museum of Nature’s best-known botany curators. With this connection in mind, she called the station and had an interview of her own.

Our route in the first week took us from Whitehorse to Dawson and beyond. Regrouping in Whitehorse at the halfway mark, we then drove south and east, through northern British Columbia, and north again to Fort Liard, Northwest Territories. From there, we could access southeastern Yukon by helicopter.

The days were full—the long northern sunlight hours allowed us to do all the surveying we could stand. To preserve our moss samples for later identification and accession in our home herbaria, we put them in paper bags (2 lb Kraft, to be precise—they fit in the pockets of cargo pants) and spread them out to dry when the opportunity arose. While on the road, I spent time cataloguing the new specimens…thanking, all the while, the ancestors that furnished genes permitting me to type on a laptop in the back of a tightly-packed truck cab, without turning as green as the mossy samples!

View of landed helicopter beside river and steep cliff.

Best pilot ever! Just enough room for him to land between the Beaver River and our waterfall. When we flew along the rivers, we saw more waterfalls and seepy cliffs than we were able to land at (we’d like to come back with a boat, which is much easier to park!). Image: Jennifer Doubt © Canadian Museum of Nature.

Did we find Porsild’s Bryum? We hiked up numerous creeks and stopped at a lot of seepy cliffs where we can now say with some confidence that Porsild’s Bryum…isn’t found there! We experienced flat tires, gorgeous landscapes, wet boots, views of wildlife, bug bites, terrific exercise, learning experiences, some great discussions, and filled lots and lots of little paper bags. Nonetheless, we only saw Porsild’s Bryum at the one spot where someone had recorded it in the past—in northern B.C., where we laboured up a steep talus to confirm that it persists where Nathalie Cleavitt found it in 2003.

It was difficult to know what we’d find when we selected these hikes from the road: sometimes there was no water in the creek at the highway, but once we got higher up there were falls, seeps, and even deep snow. Image: Jennifer Doubt © Canadian Museum of Nature.

But ask us instead if we found Porsild’s granddaughter! One morning, a call arose in the truck for a coffee stop. Knowing a place with magnificent cinnamon buns nearby, Syd pulled in at Johnson’s Crossing, where we were welcomed with refreshments and friendly conversation. We soon learned that the person operating the mixer—that day only, for old time’s sake—was none other than a smiling Ellen Davignon, the author who was ready to share some stories with four travellers on the trail of a plant named for the granddad she remembered so fondly. I love that kind of luck.

My 700 paper bags of moss are now fully dried and (thanks to our fabulous summer student, Emilie Viau!) sorted into batches for identification and accession into the National Herbarium of Canada. The information gleaned from them will become part of the growing territorial biodiversity database managed expertly by the Yukon Conservation Data Centre.

One of the waterfalls in northern BC where Porsild’s Bryum was first recorded in 2003. It was a steep climb! None of the team was game to climb to the topmost falls, which is where the nimble grad students that were there a decade ago reported seeing the largest number of colonies.

Both public resources support countless projects for research, resource management, and education, and will continue to do so long after we are pushing up daisies … and moss, too!

Thinking Back, Looking Ahead: The 2014 Palaeobiology Field Season in Alberta

We’re back!

Having spent the better part of June tromping around Alberta in search of fossils, my team (Margaret Currie and Scott Rufolo) and I are home again. And as much as we spent time out there belly-aching about the weather, the insects, the lack of amenities, and so on, we miss it dearly. Same story every year.

The good news is that we had another great field season, which is reason enough to return next year. Aside from the finds I wrote about previously, we made a number of other cool discoveries.

Scott found a third, extensive microsite, which we took time to sample carefully for small vertebrate fossils, as we did at the other two. A microsite is a dense accumulation of small vertebrate fossils, which includes the smallest bones and teeth of the largest animals, as well as various parts from the smaller fauna. Together, these sites should give us a good idea about the biodiversity of the South Saskatchewan River area about 75 million years ago.

We also collected some bits and pieces of a small meat-eating (theropod) dinosaur eroding out of a hillside. Small theropod bones, like those of their avian descendants, tend to be very fragile and, unfortunately, erode quite readily. I think we got enough, though, that we should be able to tell which species we found. (Interesting side story: while collecting the theropod, we had a close encounter with a Northern Scorpion!) We were sure to nab the soft-shelled turtle mentioned in my previous blog post, too.

Surprise! While collecting the theropod, we came face-to-face with a Northern Scorpion (Paruroctonus boreus). Image: Jordan Mallon © Canadian Museum of Nature.

Did I mention the two new horned dinosaur bonebeds that we found? These are sites where we find numerous, disarticulated individuals mixed together, probably a result of their remains having been reworked by an ancient river channel.

From what we could tell, the bonebeds appear to be fairly extensive—somewhere on the order of tens of metres wide, where exposed. Uncovering these sites would have been far too much work, given our limited time and resources, but I hope to return with some students next year to develop them properly.

Bonebeds can tell you all sorts of interesting things about herding behaviour, population structure, and predation. I’m all ears

If I have one disappointment about this field season, it’s that we weren’t able to find a nicely articulated dinosaur skeleton—something to really rally around. I suppose I shouldn’t be too upset, though—at last count, it takes about 66 person-days to search out a good specimen in the ideal setting of the well-studied Dinosaur Provincial Park in Alberta. By my estimation, we’re now at about 70 days, including last year’s expedition. That means we should be due for a big find next year! I can’t wait to get back…

Curiouser and Curiouser: Our Discoveries in 2013

by Mark Graham and Lory Beaudoin

Have you made any discoveries lately? If you answer “yes” to that question, it is in keeping with one of our most dependable features as a species: our immense curiosity. We are surrounded by an ever-developing, complex world with lots of moving parts, so there are endless possibilities to discover what things are, how they work, and where and when to find them.

At the Canadian Museum of Nature, our stock-in-trade is all about discovery—species discovery. Across the broad landscape of “-ologies” that reside with our scientific experts, and throughout the 150+ years of research and collection development at the museum, we have an impressive record of finding and describing plants, animals, fossils and minerals.

Two Liropus minusculus specimens.

The identification of this species is one of the top 10 discoveries in the world for 2013, according to the Institute for Species Exploration. Above, the smaller specimen is female and the larger one is male. Image: SINC (Information and Scientific News Service; and J.M. Guerras-García, used under licence (Creative Commons BY 3.0)

The year 2013 was no exception, with 12 new discoveries! The defining achievement of these discoveries is a thorough description of the new species, presented to and accepted by the scientific community in a publication. (A full list of our publications is compiled each year in our annual report).

More specifically, in 2013 our museum scientists and their collaborators discovered five new mineral species, five new animal species and two new plant species. Bob Anderson’s work in Central America and the Caribbean uncovered three new species of weevils, like Metamasius planatus, which is found amongst the fallen palm fronds of Dominica.

In the case of Ed Hendrycks, his two discoveries were crustaceans from California, U.S.A., and Korea. One is a cave-dwelling skeleton shrimp, Liropus minusculus, that is also counted amongst the top 10 discoveries in the world for 2013 by the Institute for Species Exploration. These interesting creatures are like the baseball outfielders of the ocean, standing up tall, waving their arms to catch passing morsels of food. (Watch a video of shrimp feeding).

Michel Poulin teamed up with his European colleagues to discover two new species of diatoms (microscopic plants) from the Red Sea and the South Pacific Ocean, including Mastogloia stellae, which is found on eelgrass near Egypt.

Joel Grice was busy describing new minerals from Canada, Norway, Russia and Bolivia, such as bussyite-(Y) from the famous quarries at Mont Saint-Hilaire, Quebec.

The discovery of new species is really a starting point in science: being able to find and designate something allows for a huge range of dependable, carefully referenced inquiries and the sharing of information. We keep careful records of our discoveries because each one involves a piece of evidence, an object that becomes a part of the collection (you can rummage through our digital collection holdings at any time, or you can visit the collection in person during one of our open houses in autumn 2014).

Regular and detail views of a specimen of bussyite-(Y).

We keep these objects because the science community continues to use them in other research, over and over again. We not only share our discoveries with the scientific and professional communities, we tell our stories to the public too. Check out our latest blog posts and videos on, visit Creatures of Light at the museum, and find out about one of our travelling exhibitions coming to a town near you.

One of the most insightful things about our discoveries, and about museum collections in general, is brilliantly stated in the Many Minds Principle: “The coolest thing to do with your data will be thought of by someone else” (attributed to Rufus Pollock, Open Knowledge

Working with Bioluminescence: Firefly Replica

When I first began my internship with the Canadian Museum of Nature in early May, I was unaware of how fundamentally important creativity is to the museum. I did not expect how much I would be able to apply my experiences of visual arts to this museum setting.

My main objective of my internship thus far has been to create two replicas: one of a firefly (Photinus pyralis) and one of a bioluminescent mushroom (Omphalotus olearius). Both will be used in presentations on bioluminescence that will be offered at the museum until mid-July.

And so, in early May the brainstorming began. My original idea was to sculpt the body of the firefly out of Styrofoam. However, knowing how much I hate the sound of scraping Styrofoam, I was quick to scrap this idea. Thinking more about what materials I could use, I decided that chicken wire would work best because it is both lightweight and easily manipulated.

As someone who is math-illiterate, the beginning steps were the most difficult. With multiple trips to the Creatures of Light: Nature’s Bioluminescence exhibition and numerous searches for fireflies in Google I ultimately decided to create a firefly replica that was 50 times the actual size. Forgetting to add a few numbers here and there a couple weeks into the project, I realized that I was making a firefly 60 times actual size—evidently math will never be my strong suit.

After a few weeks of bending wires and trying to be as patient as possible, I finished the skeleton form of the firefly model. The next step in the process was to papier-mâché over the wire skeleton to create a hard outer shell that I would be able to apply paint to.

After creating the skeleton form of the firefly, I attached all the pieces together. The next step (as shown here) was to prep for the papier-mâché by covering the replica in tape. Image: Stephanie Hachey © Canadian Museum of Nature

You would think that mixing up a batch of papier-mâché would be very simple. However, given that I have non-existent cooking skills and a short attention span, it was more difficult than it should have been. After adding, removing, and then adding more water and flour to a bowl, I finally had the ability to discern how much of each ingredient was needed: one part flour and two parts water was the final working result. For those of you out there who want to create your very own papier-mâché project: don’t forget to add salt—it helps prevent mould!

After the papier-mâché process, I applied a few layers of Gesso to the replica to act as a base paint. I am currently working on applying detail and colour with acrylic paints—attempting not to get it all over my clothes, which is impossible. I hope to also add lights to the end of the firefly so that visitors will be able to see first-hand how fireflies “speak” to one another through their bioluminescent flashes.

The end-result firefly replica, as well as the mushroom replica, can be seen at the museum’s bioluminescence presentations. Don’t forget to visit the museum and check it out!

And if my experience has seemed fun to you, join me at the museum on Sundays and Wednesdays starting on July 6: I will be creating another giant mushroom with the help of the public until August 13. The experience I gained while creating the firefly will surely come in handy!

From foothills to badlands—fossil discoveries in Alberta

My team and I have been in the field in Alberta for two weeks now, so I thought I would pass along a summary of our findings so far.

As mentioned previously, I spent the first few days in the foothills of Alberta, near Bottrel and Sundre. The intent was simple: to prospect the local Brazeau Formation for signs of otherwise rare Late Cretaceous dinosaurs. I’m happy to say that we weren’t skunked— my guide, Sue Marsland, turned up a fragmentary dinosaur bone from a spot near the Little Red Deer River. It’s difficult to say just what it is from the little that remains, but it appears to be a small limb bone from an ornithischian dinosaur.

Otherwise, we found lots of leaf and marine invertebrate fossils, which are quite common in the Brazeau Formation. It’s obvious that we’re going to have to put in a lot more time exploring this area to get a better idea of what the dinosaurs of the Albertan foothills were like.

In contrast to the foothills, my time in the southeast end of Alberta has been productive so far. My team (Margaret Currie and Scott Rufolo) and I have made a number of interesting finds. Our first prospect was a horned dinosaur (ceratopsid) leg, which we didn’t collect because it was too poorly preserved.

We’ve also turned up two microsites, which contain abundant fragmentary remains of fossil vertebrates such as fish, turtles, crocodiles, and dinosaurs. These sites are ideal for getting a handle on the local biodiversity of the time. We found a ceratopsid bonebed, which has so far produced some limb bones and vertebrae, and a small brow horn.

We also collected a forward-curving ceratopsid nose horn, probably of a Centrosaurus, which are common to this area. The complete carapace of a soft-shelled turtle was also uncovered; we will return to collect it closer to the end of our trip (read about the collecting of a turtle shell found last year). We will also be bringing home some bones for the kids’ fossil prep station in the Talisman Energy Fossil Gallery.

All in all, I’m quite happy with our efforts so far. We’ve got a number of finds on the go, despite the difficult and often steep nature of the badlands terrain out here. Still, I hope the best find awaits us yet. I’ll be sure to post a debriefing of our field season following our return next week from Alberta. Until then, keep up on our progress on Twitter by following me (@Jordan_Mallon) or via the hashtag #CMNPalaeo.

Collecting on the Coppermine 100 Years after the Canadian Arctic Expedition: A Long Overdue Follow-Up Appointment

In a few short days, Canadian Museum of Nature botanists Dr. Jeff Saarela, Roger Bull and yours truly will depart Ottawa, bound for the Arctic hamlet of Kugluktuk, where adventure and new plant discoveries surely await us. For the next month, we will be documenting and collecting the vascular plants along the Coppermine River—a Canadian Heritage River and paddling hotspot—from the tree line to the coast, a roughly 40 kilometre-long transect of Arctic-plant biodiversity.

A map showing relevant locations.

Located in the western mainland of Nunavut (the Kitikmeot region), Kugluktuk is a vibrant community of 1500, and serves as the hub for our travels along the Coppermine River.

From Kugluktuk, a helicopter dispatched by the Polar Continental Shelf Program—Canada’s Arctic logistical support group—will take us to Sandstone Rapids, the first of three camps that we will establish along the river. Here, the favourable microclimate (warmth and shelter from the wind) provided by the Coppermine River Valley coaxes the tree line to its northernmost point in Nunavut.

These spruce groves hosted a Canadian Arctic Expedition camp in the winter of 1915, and we are hoping to find these historic trees and sample them for the National Herbarium of Canada. Unfortunately, as the CAE passed through this area in winter, there are very few collections from that location and that era in our herbarium—a gap that we will soon fill!

From Sandstone Rapids, we will move north along the Coppermine, travelling by helicopter and collecting on foot until we reach Kugluk/Bloody Falls Territorial Park, a place known for both its infamous past, and for its present as “the” park for the residents of Kugluktuk. There, we will document the flora of the park—data that will contribute to the understanding and management of the park’s ecosystems for years to come.

Finally, we will boat back into the community of Kugluktuk and spend a week collecting the plants within and around the town. We will cap off the trip with a big community presentation, giving the citizens of Kugluktuk the first chance to learn about our findings along the river.

This “spruce-to-shore” expedition allows us the unique opportunity to collect plant species along an ecological gradient from boreal forest through to low Arctic tundra. In particular, a complete assessment of the floristic diversity at the tree line will allow for (relatively) rapid assessment of climate change impacts in the future, as the taiga-tundra ecosystem is projected to be amongst the first impacted ecosystems.

As with our previous trips, we will live lightly on the land: camping in remote areas, eating delicious dehydrated food (cooked by our “chef extraordinaire” Roger), and aiming to collect over 1000 plants for the herbarium. Unlike our previous expedition, a paddling trip on Baffin Island, we’ll leave the boats at home; the rapids on the Coppermine are a bit too extreme for us, and it wouldn’t do to lose our collections down the river!
