Lena River, Siberia - Research Project
Biogeochemical Fluxes in Arctic Rivers, Lena River, Siberia
21 May - 12 June 2004

In June 2004, a group of participants in the PARTNERS (Pan-Arctic River Transport of Nutrients, Organic Matter, and Suspended Sediments) project will travel to the Lena River in Siberia to sample river water chemistry as a means to study the origins and fates of continental runoff. The PARTNERS project is a 5-year project funded by the US National Science Foundation's Arctic System Science Program. Understanding sources and fates of river discharge is important because rivers make an enormous contribution to the freshwater budget of the Arctic Ocean. General Circulation Models predict river and freshwater changes with continued global warming, with major consequences for global ocean circulation and climate. Already, large-scale changes in the arctic hydrologic cycle are evident, including increasing discharge in major Eurasian arctic rivers.

The Lena River is located in the Sakha Republic (Yakutia), in Siberia. It is one of the longest rivers in the world and flows from its source in the Baikal Mountains into the Arctic Ocean via the Laptev Sea. The Yakutia region of Siberia is situated in north-east Eurasia, and is known for the lowest temperature ever recorded in the northern hemisphere - 96°F (-71°C)!

Meet the Teacher:
Amy Clapp teaches 4th, 5th, and 6th grade science and 5th grade writing at Salisbury Community School in Vermont. She is a student in the Vermont Science Initiative, a graduate program intended to create a cohort of science teacher-leaders, and has been awarded several grants and awards in recognition and support of her integration of scientific inquiry in the classroom. Amy is looking forward to participating in TREC to give her valuable experience to grow as a teacher leader and to give her an exciting and interesting perspective to share with colleagues and students. Her hope is to draw students and teachers into the process of scientific discovery as well as to show the many ways that scientists use literacy in their work. Learn more about Amy and her TREC experiences through the "Teacher\'s Journal," "Ask the Teacher," and "Photo Album" links in the "Lena River, Siberia" menu to the left.

Meet the Researcher:
Max Holmes is a staff scientist at the Marine Biological Laboratory in Massachusetts and is interested in watershed biogeochemistry and hydrology, particularly as influenced by climate change. Most of his current work is in the Arctic, focusing on investigation of land-ocean linkage by large rivers in Russia, Canada, and Alaska. Max is looking forward to linking the PARTNERS project to K-12 educators and classrooms through the TREC program. Click here to learn more about Max and his research.
