Return to the Arctic

Our next group of BioArt students are preparing for their field season in the Arctic! We have 10 students traveling with us again this year, half science majors and half art majors. They will be working together to conduct independent research in Arctic ecosystems and communicate their research through bio-art. We are looking forward to doing that again from Kilpisjärvi Biological Station in northern Finland, our home away from home!

Right now, we are still at Arizona State University getting ready for the trip. We've started by discussing the similarities between science and art, and thinking about the skills that are similar to both fields. We've been using our skills in observation, interpretation, analysis, and creativity to think about both science and art. We've been practicing those skills in the Sonoran Desert with a little bit of field work... which in May is hot enough to make us really appreciate the fact that we'll soon be in the Arctic!
We've also been in the classroom learning some basics of Arctic ecology, so that students can start to plan their research projects and how they will communicate them creatively through art. Even though we're in the Sonoran Desert in the early summer, we've pretended that we're already in the Arctic to learn go over some field safety that we'll use in Finland. We can now successfully use signal mirrors in case we get lost and treat our teammates for hypothermia!
Learning to use signal mirrors... and how to use our cell phones as signal mirrors.
Practicing hypothermia wraps so that we can save Jeremy!
We have another week of class here at ASU, and then we pack up and leave for Finland!

BioArt Exhibition

The goal of the course in Kilpisjärvi was for students to be trained in both independent scientific research, as well as the communication of that research through creative works of art. Science and art students combined their skills and backgrounds to create some amazing work! This week, the official exhibition of their work began. They created research posters explaining their experimental science, which were displayed next to their artistic creations reflecting that science.
Each of the 5 projects are displayed like this. The science poster is hung next to their artistic work, giving both a scientific and a more creative expression of each research project.
The five scientist+artist pairs each have a project on display. I told you a bit about the students' research projects in previous blog posts, while we were in Finland working on them. Now, I can share with you the completed results! Here are the five projects. You can open their research poster to read about the science, and the photo of their art project shows how they also communicated that science in a very engaging way.
Tiff and Guillermo created a clay tile mosaic of the soil microarthropods they studied along the elevational gradient of a mountain fell. The individual depictions of collembola and mites are connected in a mosaic that mimics the Sami flag, an emblem of the native people in Lapland. Read about the soil microarthropods of Saana in their research poster!
Kylie and Gina represented their 3 experimental treatments of natural lake water, increased temperature, and decreased pH on the phytoplankton in Lake Kilpisjarvi through a 3-segment enhanced image of Asterionella taken from their scientific sampling. Read about the impacts of temperature and pH on lake phytoplankton in their research poster!
Stephanie and Diego created paintings representing the current plant community and projected future communities in 2050 and 2100, to show how the abundance and composition of the plant community could change with future climate change. The dots represent individual plants, with each species having a different color. Some plants will become more abundant, and others will decrease, changing the overall composition. Read about the projected change in reindeer-supporting plants in their research poster!

Ezra and Manny created a 3-D installation that recreates the lichen, moss and algae communities growing on rocks in the Arctic. showing just how abundant life on rocks can become. A side-display identified the lichen and showed how they measured the communities on rocks using their grid system. Learn how lichen diversity on rocks changes with elevation in their research poster!
Christina, Andrew, and Brooke created two different creative projects (since they were a 3-person group). On top are collages representing the birds of Kilpisjärvi (titled "Nature", on the left) and the impact humans can have on these bird populations (titled "Encroachment of Man", on the right). They are framed by ribbon hand-woven by Christina using local wool and traditional Sami weaving patterns.The TV is running a short film using footage and sound clips of the birds around Kilpisjärvi, to a reading of the Kalevala (a Finnish folklore poem). Read about the resilience of Kilspisjärvi birds to human disturbance in their research poster!

The exhibit opened this week, with a reception Wednesday night. The student scientists and artists discussed their work with students, faculty, and the public, relieved now that their hard work paid off!
Brooke discusses their bird research with visitors.
Kylie discusses phytoplankton (and photoshop) with visitors. (The two people on the right are her grandparents!)
Their works are on display on the 3rd floor of the Fletcher Library at ASU's West Campus through October 3, 2018. It's free and open to the public!

From Kilpisjärvi to Tromsø

While we were at Kilpisjärvi, we got to enjoy a bit of the local culture and cuisine. The kitchen staff made us a huge batch of pancake batter, that you traditionally make over a fire. We did it in the replica Sami goahti hut that is at the station. Put a little cloudberry jam on it, and mm mm mm!
Brooke and Tiff got good at flipping the pancakes, and even took requests for pancake shape.

Also, on our last night at the station, the cook made us a delicious dinner of local fish. It's hard to find a store here that sells fresh fish, because most people just go catch the fish themselves. (So who would buy it, when it's so easy to get it yourself?) The cook asked her friend to go fishing for us. So our last dinner at Kilpisjärvi was white fish straight out of Kilpisjärvi!

It was a great stay at the research station. Students have done a very good job on their BioArt research and communication projects. And not only that, but throughout the week, we got to learn a lot from local scientists and artists who work in the BioArts. They helped demonstrate just how successfully the sciences and arts can be intertwined. For example, Leena Valkeapää showed us a project at the Pikku-Malla nature reserve where she (an artist) and a scientist are testing the use of two native plant species to re-vegetate damaged soil. The design of the experiment tests whether the two species successfully revegetate the soil, and also whether the geographic origin of the individual plants matters for its success. Leena, the artist, worked with the scientist to design a layout that is both scientific to test the hypotheses, but also visually aesthetic (...once the plants start growing! They are still very small right now.)
Leena shows the students the marking system for the pattern of crowberry and ligonberry plants used in the revegetation experiment.

We left Kilpisjärvi yesterday morning and drove to Tromsø, Norway which is the point of departure for the program. We took the same bus that brought us to the station at the beginning of the program. You can compare this photo to the one from that early trip. The students who are awake are still smiling, but there are a few more sleeping students on this trip. We wore them out!

While we are here in Tromsø, though, we might as well keep learning and experiencing science and art! One of the places we went to is Polaria, an aquarium to learn a bit about marine science, which is not something we got to see up in the mountains. When it was getting close to the time to leave, I didn't see any of our students walking around anymore, so I had to search a bit for them. Of COURSE I found a cluster of them in a corner peppering the seal handler with questions:

We had a good day in Tromsø (though a bit wet and cold... it's been rainy), and ended with a group dinner at a restaurant on the fjord. Now, the students are all on their airplanes headed home. They still have work to do to wrap up their projects, which will be exhibited at the gallery on campus in September. Stay tuned for updates on that!

Take a likin' to a lichen

One of the types of organisms that can survive well in the harsh Arctic climate is lichen. There is quite a lot of it growing all around, on rocks, trees, and just about anything sitting still. A lot of the students on the program have enjoyed inspecting the lichen close up. Ezra and Manny chose to study it for their independent project.

Manny and Ezra measured the abundance and diversity of lichen growing on different sizes of rocks as you go up in elevation on Saana. They want to know how the climate difference with elevation influences lichen communities, but also whether the size of their habitat changes how elevation influences the communities. They hiked up the trail at Saana, and stopped at regular intervals to investigate the lichen on rocks. At each point, they randomly chose 3 small, medium, and large rocks.

Ezra and Manny photographed the community growing on the rock within a 25 cm x 25 cm grid. Back at the station, they are using the images to measure the percent of the area covered by different types of lichen. It is very difficult to identify many lichens to species, often requiring molecular sequencing of the DNA, which is not possible in our short stay. So they are categorizing them by color and growth form to estimate diversity.

They have completed their field work, with 10 intervals over the elevation photographed. They have a looooot of photos to sort through and count before they can determine how the communities change with elevation, and whether the size of their habitat surface matters over elevation.

When their results are complete, they plan to communicate the diversity of these communities through an art installation, where they will create a room-sized replica of Saana, with rocks and water and lichen, so that the viewer can see, hear, and feel like they are standing there with us in the Arctic, learning about the lichen and their habitat.

Reindeer food in Lapland

Reindeer are a common sight here in northern Finland. They are a domesticated livestock that are a well-known part of the livelihood of the Sami people, a native culture here in Lapland. The reindeer are owned and herded by particular families, but are allowed to wander in their designated areas. We see them around the state forest lands here around the research station, and even on the road in town!

Andrew shared this photo of a reindeer he met while doing his field work.
Diego and Stephanie are interested in the plants that provide food for these reindeer. They eat a lot during summer when there is plenty of vegetation available, including quite a lot of the species here around the research station. Stephanie and Diego learned from Rauni, the station's resident plant expert, which species are eaten by the reindeer, and chose to focus on the birch and willow species. They then surveyed the forests around the station to measure the actual abundance of these plants. They measured the abundance using belt transects:
Diego in the distance measuring one of the replicate belt transects.

Diego and Stephanie ran many transects all around the station, to calculate the abundance of birch and willow in all directions from the station. The number of plants in each transect can be used to calculate the abundance per square meter of forest.
Stephanie measuring another one of the replicate transects!

They are most interested in how the abundance of these plants might change in the future, with projected warming from climate change. Would there be more or less of these plants available to feed the reindeer? We don't have enough time at the station to test this ourselves, because it takes years to understand how a species will change with a warming climate. Instead, they are spending a LOT of time looking at published research from other scientists who have already conducted these types of studies. This means a lot of computer time using the library resources!

Stephanie and Diego in the common room, reading and discussing.
Diego and Stephanie are using the data they find to make mathematical projections into the future. They are finding published results of the magnitude of changes in birch and willow species in warming experiments conducted here in the Arctic. Then, they can apply these changes to the abundances that they measured during their field work, to predict what amount of these plants might be available as reindeer food far into the future.

They will communicate their results through a creative mixed-media project. They plan to use aerial photographs of their study region, repeated in a line to represent a timeline from now into the climate future, one for every decade of their projection. They will project colors onto the photographs that represent the species they studied, and the colors will become more or less abundant as you move forward in the timeline.

Phytoplankton bonanza!

One of our student teams, Kylie and Gina, have been studying the phytoplankton that live in the lake next to the station. ("Järvi" means "lake", so Kilpisjärvi is the name of the lake as well as the town.)  They want to know how abundant plankton are in the lake, and how they will respond to warmer temperatures. It is generally known that many types of phytoplankton reproduce more when water is warmer, but this is mostly studied in nutritious waters in warmer regions. Nobody has looked at how plankton will respond in this particular lake. Actually, Gina and Kylie couldn't find any information about plankton in this lake at all!
Some of the phytoplankton that Kylie has photographed. You can see several different types.

To conduct their experiment, they took water samples from the lake in jars.
Gina collecting one of the jars of lake water.
They calculated the abundance of phytoplankton in the bottles from a small subsample, then put the bottles into little greenhouses that they built on the shore of the lake. They built three greenhouses. One was covered and not vented at all, to make the temperature around the bottles a few degrees warmer than it currently is. Another greenhouse had some holes poked in the sides to cool off a bit, and create temperature is only a little bit warmer than it currently is.  The other one was very highly vented, to essentially be the same temperature as the current outside air. (They didn't want to just leave those bottles uncovered, because it's possible that the greenhouse itself interrupts light coming in for photosynthesis. So, it is receiving the same amount of sunlight as the other green houses, but not staying warmer.) They have thermometers in each greenhouse measuring the air temperature.

After a couple days in the greenhouses, Kylie and Gina are busy counting their phytoplankton from each one. If their hypothesis is supported, they will count more plankton in the jars that were sitting in the warmer greenhouse. This takes quite a lot of work, because neither Gina nor Kylie were plankton experts when they got here. They have learned how to recognize the different types of plankton and how to use the big inverted microscope.

Kylie and Gina will be communicating their project through photography. They will be creating what is called a "composite image". The main focus of the image will be a photograph of the phytoplankton they collected, but the background will have other images layered in that represent the environment the phytoplankton were living in. If that doesn't quite make sense, don't worry. I had a hard time picturing it from the description, too, until Kylie showed me an example. It looks cool! That means that they are doing a lot of computer editing of images, along with their microscope work.

Temperature was their initial variable that they studied. Now, they have also acidified the water, to simulate potential impacts of CO2 dissolving in water (which dissolves into carbonic acid and acidifies water) and other forms of pollution. They will again count their plankton at those temperatures to see if they are impacted by both temperature and acidification. They will be microscope pros by the end of the course!

Birds galore

Today I helped one of the student teams with their research project. Andrew, Brooke, and Christina (the ABC, as we call them), are looking at how bird behavior might be impacted by human activity in Kilpisjärvi.

Kilpisjärvi is actually a fairly new town, only about 10 years old. We also have a fairly main road running by the station, the E8 that goes into Norway. Of course, the traffic on a "main road" in Lapland is very different from a "main road" in Phoenix! But many cars and trucks, and their associated noise, are a factor here. Brooke, Christina, and Andrew wonder how that impacts the birds who live in the otherwise undisturbed habitat here around the research station.

For the past several days, they are counting birds at regular intervals from the E8 road to see whether birds avoid being near the road. They also then create disturbances at each of those regular distance intervals to see if the birds near the road deal with disturbance better than birds further from the road.

To count the birds, all three of them spread out along the road, then walk to their first 50-meter stopping point. I was one of the three counters today. We sat still at our marked spot to let the birds forget we're there, then created a disturbance using the horn sound on our phones. We then counted how long it took for birds to come back, and how many of them we saw of different species. Then, we moved to the next spot and repeated the process.

Because the three counters are spread out, they are able to count the birds over a fairly large area. I was on the end, at transect "C". Here, you can just barely see Brooke on transect "B", beyond the end of my finger. And you will maybe notice the blue flagging, marking my spot to stop and count.
I enjoyed helping, because it meant I could sit quietly and observe. I saw a bluethroat, pied flycatchers, and house sparrows. I also happened to see a vole and some bees!

Christina, Andrew, and Brooke are also working on collages that will communicate what they learn about how birds react to the human disturbances. They have been collecting natural materials that they will use and making castings of bird sculptures. Andrew will be making his collage in video format, which is his favorite format. You can find him around the station in the evenings getting his recordings. Near the bird feeder is a great place to record the redpolls and bramblings!

So, students today have continued to work a bit on their projects, even though technically they had the day off from classes. (They just work THAT hard!) We did plan one activity for them today, which was to go to the "3-Country Cairn". It's the point that marks the corner where Finland, Norway, and Sweden meet. It represents how the borders have fluctuated  over history when Finland was ruled by the Russians, the Swedes, and fought for their independence. At the end of WWII, they celebrated the departure of the Nazis by raising a flag over this cairn. Since we've learned a bit about WWII history as we walked along or by remnants during our field work, it was interesting to visit this historic location built in 1926 (to replace the one built in 1897 that eroded). So, we're learning a little history, along with our BioArt!
