Northern Alaska Coastal Ecosystems

What Are They Doing?

Water sampling with students from Kaktovik, AlaskaWater sampling with students from Kaktovik, Alaska Coastal ecosystems of the Arctic receive extraordinarily large quantities of terrestrial organic matter through river discharge and shoreline erosion. The fate of this organic matter is of both local and global interest as it relates to biological production in the coastal ocean as well as the global biogeochemical cycle. Terrestrial organic matter has the potential to provide an important source of carbon and energy to support and maintain organisms and food webs in coastal waters during much of the year. The goal of this research was to determine how seasonally distinct terrestrial inputs of water and organic matter influence microbial and animal communities in coastal waters of the Alaskan Beaufort Sea.

Research sites ranged from lagoons to open coastal systems and each site was used to examine linkages between biological communities and organic matter inputs from land. Measurements of water and sediment chemistry, and benthic and water column community characteristics were used to evaluate the importance of terrestrial inputs under different hydrologic/hydrographic conditions.

Understanding the fate of terrestrial carbon in arctic coastal waters is especially important now as the arctic system enters a period of rapid climatic change. Changes in terrestrial organic matter export could influence the productivity and roles of organisms in arctic coastal waters. Such shifts have consequences for local human populations that fish and hunt for subsistence and for the broad scientific community interested in land-sea coupling.

In addition to their research, the team continued their successful K-12 outreach program entitled "Climate Change in the Arctic: An Interactive Program Linking Scientists with K-12 Students". This included the continuation of a summer field science program for native Kaktovik K-12 students. The Village Council has continued to express keen enthusiasm to involve school children in hands-on science activities that support learning of key science concepts.

In addition, PolarTREC teacher Jill Smith learned about the cultural importance of the annual bowhead whale hunt that began while she was in residence at Kaktovik. She had the opportunity to share this information through real-time video connections with her students in her home classrooms in Texas, enabling students from Texas to have direct dialogues with students in rural Alaska.

Where Are They?

Ice on the Beaufort SeaIce on the Beaufort Sea The team was based out of Kaktovik, Alaska, a small village on the shore of Barter Island off the coast of northern Alaska. The team traveled on a 27 foot Boston Whaler to access a set of 12 field sites along the Beaufort Sea coast. Until the late nineteenth century Barter Island was known as a prominent location for fishing and bartering for Iñupiat from Alaska and Inuit from Canada. Fewer than 300 people live in Kaktovik, and due to its relative isolation it is still highly dependent on a subsistence lifestyle that includes fishing and hunting—primarily for caribou, seals, and bowhead whale.

Space weasel puts on his space sombrero.
I spent most of the day at the high school either with the students or preparing journals. The science students were studying states of matter and Mrs. Sobey and I both contributed to today's lesson. I hope to use the activity with our students back home. They started with a reflection of Friday's oil spill clean-up lab. Space weasel puts on his space sombrero to model the difference between mass and weight : ) Liquids take the shape of their container!

Principal Todd invites the whole school to sing Happy Birthday to Mr. Joe
Today I got to visit with students in high school, middle school AND elementary school. We started the day with Dr. Ken sharing some photos and talking with the high school students about his adventures in the Chukchi sea on the Coast Guard Ice Breaker "Healy". The presentation focused on observable changes in the Arctic and their effects on the native populations that are closely tied to and heavily dependent on that environment for subsistence living. Ken has been visiting this area since the late 70's and has worked with many of these students and their families over the years. Mid-...
Ted and John observe Stephanie's Techni-Ice hydration skills.
Today begins with the nerve racking weather monitoring as the team tries to plan for their longest trip in the field. It is a long trip anyway, but adverse weather can make it significantly longer. They have been watching the wind direction and anticipating wind shifts over the next 15-20 hours. The morning started with overcast skies, cool temps and winds out of the east. True story; in the time it took me to walk to the school and talk briefly with a couple of teachers (15-25 minutes) a DENSE fog settled over Kaktovik. That fast! Now, I suppose that they have another set of...
 Carrie Harris separates one DNA sample into two.
We planned a relatively short day in the field today (~4-5 hours) to do some trawling and sediment grabs in the adjacent waters. The whole house sprang into action, as those departing in the boat prepared to do so, those remaining took on projects that could be completed in the bunkhouse. Carrie Harris separates one DNA sample into two using sterile technique. Tara makes ice to help transport all of the samples to Texas and other locations. As we move away from the shore, Kaktovik can be seen in the distance behind the protective snow fence. Dr. Ken Dunton dares to take a bite of the...
Miss Flora, Lucy, Collin and Madeline check out the progress.
The Lab Activity In the high school science classes today, we did an oil spill clean-up simulation lab. I had first done this lab with my GK-12 fellow Chris Wilson in the 2008 school year. I had forgotten how effective it was until today. The students here really got into it as they did in Port Aransas years ago. We "polluted" fresh water with vegetable oil and offered a variety of materials to remove the oil with the goal of reclaiming the original volume of water, unpolluted. We offered sponges, cotton balls, gauze and doggy pads as absorbents and craft sticks, pipe cleaners and nylon...

Dr. Kenneth Dunton is a biological oceanographer whose research is focused on estuarine, coastal, and shelf processes. Although his work spans from the Arctic to the Antarctic, his continuous studies of the arctic coastal ecosystem have spanned three decades. Dr. Dunton became involved with arctic studies involving kelp beds in 1977. His research also includes examining the distribution and biomass of benthic biota and the application of stable isotopic signatures to assess changes in trophic structure. Such measurements can help identify processes that are sentinel indicators of global change.

He has continued this work in the Chukchi Sea under funding from the Bureau of Ocean Energy Management (BOEM) and under a grant from the NSF to examine the linkages between watersheds and the nearshore lagoons of the eastern Alaskan Beaufort Sea. Dr. Dunton has published more than 80 peer-reviewed papers and has supervised over 20 graduate students and 11 post-doctoral fellows. He is active in K-12 outreach, obtaining two NSF grants that partner teachers and graduate students in K-12 classrooms. He implemented the annual summer science field program for kids in 2008 in partnership with the City of Port Aransas and the Port Aransas school district. He also implemented a summer science program for the native school children of Kaktovik, Alaska, on the Beaufort Sea coast in conjunction with the Arctic Refuge (USF&WS) that started in 2007. He obtained his BSc in biology from the University of Maine in 1975, his MS from Western Washington in 1977, and his PhD in oceanography from the University of Alaska-Fairbanks in 1986.

Dr. Dunton is currently a professor in marine science at the University of Texas at Austin. He has lived in Port Aransas since he and his wife Susan arrived from Fairbanks in 1986. They have three grown children, two of whom graduated from TAMU College Station and one from UT-Austin. He routinely cycles, surfs and swims. Learn more about Dr. Dunton here and here.

Dr. James McClelland studies nutrient dynamics in the environment, with a strong emphasis on understanding the role of land-derived carbon and nitrogen in coastal ecosystems. Environmental changes as a consequence of human activity, including changes in land use, land cover, and global warming, provide the context for much of his work. These changes are having a profound influence on transport of water and water-borne material from rivers to estuaries. In turn, changes in river inputs to estuaries are altering fundamental ecosystem properties such as primary production and food web structure. Much of Dr. McClelland's work has focused on the Arctic over the past decade. He co-founded the Arctic Great Rivers Observatory (www.arcticgreatrivers.org), a pan-arctic effort that has greatly improved estimates of river inputs to the Arctic Ocean and established a solid baseline for tracking future changes. His work in the Arctic has also included more focused studies on the North Slope of Alaska, examining nutrient transport and processing at a variety of scales. Dr. McClelland earned a B.S. in zoology from the University of Washington in 1991 and a Ph.D. in biology from Boston University in 1998. He became a faculty member at the University of Texas Marine Science Institute in 2006, where he is currently an Associate Professor.
