Adaptation Strategies in the Face of Climate-Driven Ecological Transformation: Case Studies from Arctic Alaska and the U.S. Great Plains
Climate change is already affecting ecosystems, and will likely trigger significant and permanent changes in both ecological and human communities. Such transformations are already occurring in the Arctic region of Alaska, where temperatures are warming at twice the global average and causing some ecosystems to transition to new states. Arctic warming has led to coastal erosion that has forced human communities to relocate and a loss of sea ice that has forced marine mammals, such as polar bears and walrus, to adapt to a more terrestrial mode of living. Meanwhile, in the Great Plains of the U.S., past interactions between land and water use during the Dust Bowl and recent high rates of depletion of the Ogallala...
Using Automated Identification System (AIS) point data acquired from Alaska Marine Exchange’s station-based networks in the Aleutians and Bering Strait and satellite platforms maintained by ExactEarth to produce monthly and seasonal summaries of commercial shipping intensity by ship type. AIS data evaluation and spatial characterization will be completed by a University of Alaska, Fairbanks PhD student in cooperation with the Wildlife Conservation Society. Final layers will be made available to managers and stakeholders through the Arctic E. Their expanded regional layers will be analyzed by a group of leading NGOs including: Alaska Marine Conservation Council, Audubon Alaska, Oceana and the Wildlife Conservation...
Partners developed a simulation model to better show how various projections associated with increased marine traffic in the Bering Sea might look in the coming decades. These simulations are able to help communities and managers better understand future patterns of traffic in the Bering Sea region as a whole, and look more specifically at possible changes in key areas of concern like the Bering Strait.Following vessel activity analysis and considering vessel type, transit routes, route timing, routing speed, and ports of call, we developed a novel agent-based, spatially-explicit, baseline model of current marine vessel traffic patterns. We then applied projections about changes in traffic volume from a report by...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
