What Are They Doing?

Thawing permafrost
Thawing permafrost

Tremendous stores of organic carbon frozen in permafrost soils have the potential to greatly increase the amount of carbon in the atmosphere. Permafrost soils may thaw sporadically, and melting ground ice can cause land-surface subsidence called "thermokarst failures". These failures change the rate and amount of carbon released with the unanticipated outcome being that soil carbon can be mixed-up from a depth and exposed to sunlight as the land surface fails. Sunlight can photo-degrade organic carbon and alter the carbon's ability to support bacterial respiration to produce carbon dioxide. Whether UV exposure will enhance or retard the conversion of newly exposed carbon to carbon dioxide is currently unknown—in this study team is providing the first evidence that this alteration will be amplified by photochemical processes and their effects on microbes.

The research team is trying to understanding exactly how sunlight and bacteria degrade dissolved organic matter by determining how fast these processes convert newly released dissolved organic matter to carbon dioxide, compared to dissolved organic matter already in surface waters. The team will accomplish their research objectives with a series of laboratory experiments to determine rates of photodegradation and microbial processing of dissolved organic matter from different sources, and a series of landscape comparisons and sampling transects to characterize dissolved organic matter degradation in small basins and large rivers extending from the headwaters to the Arctic Ocean. Ultimately, this research will attempt to answer questions such as whether carbon export from tundra to oceans will rise or fall and how reactive the exported carbon will be. The team hopes to be able to measure the ultimate impact of impending disturbances, including climate change, on the net carbon balance of the Arctic and its interaction with the global carbon cycle.

Where Are They?

The research team was based out of Toolik Field Station, an 8-10 hour drive north from Fairbanks, Alaska. Toolik Field Station is operated by the Institute of Arctic Biology at the University of Alaska Fairbanks and has hosted hundreds of researchers and students every year since 1975. From the field station, the team traveled to their sites by foot, truck, boat, and helicopter. The weather near Toolik Lake can be wet, cold, snowy, muddy, buggy, and occasionally sunny and beautiful.

Bruce Taterka - Teacher
Teacher
West Morris Mendham High School

Bruce Taterka teaches environmental science and theory of knowledge at West Morris Mendham High School in Mendham, New Jersey. Bruce is a trustee of the Schiff Nature Preserve in Mendham where he has designed and led after-school environmental education programs for middle and high-school students. In 2009 Bruce won an Earthwatch Fellowship to study trophic relationships in the cloud forest of Ecuador, and in 2010 he was a NOAA Teacher at Sea working aboard NOAA ship Oregon II in the Gulf of Mexico during the BP oil spill. Bruce has rafted and paddled the waters of the Americas from the Tena River in Ecuador to British Columbia's Queen Charlotte Islands to the Colorado, Snake, Allagash, and Passaic rivers in the U.S. In 2011-2012 Bruce worked on federal and state education policy as a U.S. Department of Education Teaching Ambassador Fellow and served on the New Jersey Department of Education's Evaluation Pilot Advisory Committee.

Prior to his career as a teacher, Bruce worked for seventeen years in the environmental industry, first as an environmental consultant and then, after earning his law degree at night from the Pace University School of Law, as an environmental lawyer at the international firm Latham & Watkins. Bruce is currently co-authoring New Jersey's Environmental Literacy Plan with his wife, Tanya Sulikowski, who is an environmental educator working on her MS in ecology at Montclair State University. Bruce has a BA from Vassar College and MS in geology from the University of Massachusetts at Amherst.

Rose Cory - Researcher
Researcher
University of Michigan

Dr. Rose Cory works in the Arctic where climate warming is thawing frozen soil which may release tremendous stores of dissolved organic carbon to the Earth's surface. After having been trapped for millennia in the frozen soils this new carbon then becomes part of the modern carbon cycle. Dr. Cory finds that exposure to sunlight accelerates the return of this dissolved organic carbon to the atmosphere as carbon dioxide, which may further increase the rate of global warming. Because climate change is influencing our planet's evolution, understanding the fate of newly released carbon will help predict our future as a planet and society.

George Kling - Researcher
Researcher
University of Michigan

George W. Kling is a professor in the Department of Ecology and Evolutionary Biology at the University of Michigan. He primarily studies aquatic ecology and biogeochemistry, and his research has focused on carbon and nutrient cycling, on using stable isotopes to understand trophic interactions, and on the integration of lakes and streams in a landscape context. His recent research has examined the role of microbial diversity in ecosystem function. He has worked internationally on arctic lakes and streams for approximately 25 years, and on tropical lakes in Africa.

Kling's scientific outreach to the public through interviews about his research on climate change and on the killer lakes of Cameroon includes articles in magazines and newspapers (e.g., National Geographic, Smithsonian), T.V. and radio broadcasts (e.g., CNN, BBC), and television films (e.g., BBC, Discovery). He has met regularly with U.S. Congress members to discuss issues of climate change and scientific integrity, and was lead author of the Union of Concerned Scientists – Ecological Society of America publication 'Confronting Climate Change in the Great Lakes Region' (2003). Kling is an associate editor for Limnology and Oceanography (2001-), an elected Fellow of the American Association for the Advancement of Science (1997-), and received a National Academy of Science Young Investigator Award (1993), a NSF Presidential Faculty Fellowship (1995), the United Nations Sasakawa Award (Certificate for Disaster Reduction, 2001), and the ASLO Ruth Patrick Award (2007).

If you're a high school or college student and think it might be interesting and fun to do research at a place like the Toolik Field Station for a summer, here's what I want to tell you: You CAN do it. In fact, there are a lot of college students working at Toolik this summer. Two of them are on…
From May 26 through July 17 the sun never sets here at the Toolik Field Station. This is a 1-minute time lapse video showing the midnight sun over Toolik Lake. http://youtu.be/Y0c4MObqF9w Midnight sun over Toolik Lake.
I’ll be leaving Toolik in few days, heading for Fairbanks to meet Tanya and travel around Alaska. Spending 3 weeks here has been an amazing experience and I’m looking forward to bringing the tundra into my environmental science classroom this fall. Molting caribou near Imnavait Creek In the…
