Stream Communities and Ecosystems Monitoring in Alaska's Arctic Network
O'Donnell J. Stream Communities and Ecosystems Monitoring in Alaska's Arctic Network. 2012. National Park Service
Streams and rivers are important components of and critical resources within arctic watersheds. Recent climate change in the Arctic has altered the magnitude and seasonality of stream discharge, stream temperature, the chemical composition of stream water, and stream habitat. Still, large uncertainties exist regarding the spatial extent of these changes and the timing of stream ecosystem responses to projected climate change. The Stream Communities and Ecosystems vital sign is one of 19 vital signs within the National Park Service’s (NPS) Arctic Inventory and Monitoring Network (ARCN). The ARCN is comprised of five NPS park units, including Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, and Noatak National Preserve. The overarching goal of our monitoring program is to detect long-term change in physical, chemical, and biological components of arctic stream ecosystems.
