Toward a Predictive Model of Arctic Coastal Retreat in a Warming Climate, Beaufort Sea Alaska

US Bureau of Ocean Energy Management (BOEM) - The long-term goal of this project is to quantify the environmental drivers of extremely rapid coastal erosion in the Arctic, and to begin developing predictive models of future rates of coastal erosion resulting from climate change. Our study is focused on the Beaufort Sea coast within the National Petroleum Reserve – Alaska (NPR-A), approximately halfway between Barrow and Prudhoe Bay. ...

Greenhouse gas mitigation can reduce sea-ice loss and increase polar bear persistence

US Geological Survey (USGS) - Polar bears live only in marine regions of the Northern Hemisphere where sea-ice cover persists for long enough to allow them sufficient opportunity to access their marine mammal prey. Recent declines in summer Arctic sea ice have coincided with declines in some polar bear populations, and a US Geological Survey report in 2007 projected that with 'business as usual' emissions, polar bears could...

Global Tundra Vegetation Change

Canadian Cryospheric Information Network (CCIN) - These data were collected in conjunction with two International Polar Year (IPY) synthesis projects, looking at 1. Vegetation responses to warming in sites worldwide and 2. Long-term changes in unmanipulated control plots. Plot-based data was collected on vegetation abundance (cover, point-frame hits, biomass, subplot frequency, stem-counts) from permanently marked plots, transects, and...

Survival and breeding of polar bears in the southern Beaufort Sea in relation to sea ice

US Geological Survey (USGS) - 1. Observed and predicted declines in Arctic sea ice have raised concerns about marine mammals. In May 2008, the US Fish and Wildlife Service listed polar bears (Ursus maritimus) – one of the most ice-dependent marine mammals – as threatened under the US Endangered Species Act. 2. We evaluated the effects of sea ice conditions on vital rates (survival and breeding probabilities) for polar...

Arctic Report Card

National Oceanic and Atmospheric Administration (NOAA) - The Arctic Report Card (www.arctic.noaa.gov/reportcard/) considers a wide range of environmental observations throughout the Arctic, and is updated annually. A major conclusion of the 2011 Report is that there are now a sufficient number of years of data to indicate a shift in the Arctic Ocean system since 2006. This shifted is characterized by the persistent decline in the thickness and summer...

Evaluating the bottom up effects of changing habitats: climate changes, vegetative phenology, and the nutrient dynamics of ungulate forages in the Alaskan Arctic

US Geological Survey (USGS) - For northern ungulates, such as caribou, the high seasonal variation in plant abundance and quality accentuates the need to replenish body stores during a short growing season that is critical for reproduction and winter survival. Consequently, the predominant nutritional effects of climate changes to populations of northern herbivores are likely to be mediated through vegetative changes...

Assessing the Western Arctic Boundary Current and its role in the Arctic ecosystem and climate change

Woods Hole Oceanographic Institute (WHOI) - The Western Arctic Boundary Current, which flows out of Barrow Canyon onto the continental slope of the Beaufort Sea. A multi-disciplinary mooring is located at 152o W in the center of the current, and is maintained as part of the Arctic Observing Network (AON). The AON mooring measures the physical properties of the boundary current (temperature, salinity, turbidity, velocity, ice...

Sea Ice Index

National Snow and Ice Data Center (NSIDC) - The monthly Sea Ice Index provides a quick look at Arctic-wide changes in sea ice. It is a source for consistent ice extent and concentration images and data values from 1978 to the present. Monthly images show sea ice extent with an outline of the median extent for that month (magenta line). Other monthly images show sea ice concentration and anomalies and trends in concentration.

Chukchi Sea Environmental Studies Program: Chemical Oceanography

Alaska Ocean Observing System (AOOS) - The primary objective of the ocean acidification program is to describe spatial, seasonal and interannual variability in the marine carbon cycle to assess the extent and potential impacts of ocean acidification. Secondarily, data are obtained via CTD (conductivity-temperature-depth) casts that will better characterize how much of a sink the Chukchi Sea provides for atmospheric CO2. This data...

Benthic lower trophic level food webs in the Chukchi and Beaufort Seas – baselines and relevance of sea ice algal production

North Pacific Research Board (NPRB) - This project seeks to investigate NPRB’s Arctic Focus Section Priority: Climate change effects on Arctic lower trophic food webs. Warming trends in the Arctic and increasing loss of sea ice and its associated primary production are thought to have profound effects on the energy flow on Arctic shelves. Based on information from other recent projects, we plan to fill specific gaps in our existing...

PHOTOGRAMMETRIC ANALYSIS OF COASTAL EROSION ALONG THE CHUKCHI COAST AT BARROW, ALASKA

University of Colorado (UCOL) - A variety of empirical and modeling approaches are being taken to assess the history and risk of erosion and flooding along the Chukchi Sea coast near Barrow, Alaska. Part of a broad assessment of climate impacts for the North Slope (nome.colorado.edu/HARC), this study utilizes softcopy photogrammetry and GIS to quantify coastal erosion over the last five decades. Barrow was also...

The Role of Lichens, Reindeer, and Climate in Ecosystem Change on a Bering Sea Island

Institute of Arctic Biology UAF (IAB) - Archived reports from an international controversy in the early 1890s over management of the harvest of fur seals, Callorhinus ursinus, on the Pribilof Islands in the southeastern Bering Sea provided an unanticipated record of observations on the growth of lichens in association with the prevailing climatic conditions. The abundance of lichens observed in plant communities on the Pribilof...

Enhancing forecasts of polar bear response to a rapidly changing Arctic ecosystem (Enhanced polar bear habitat models)

US Geological Survey (USGS) - Satellite radio telemetry has been an important tool for assessing distribution, activity levels and habitat use patterns polar bears. This information is necessary for development of polar bear energetic profiles. Since 1985, these data have been derived primarily from Doppler satellite telemetry. Doppler satellite telemetry provides relatively course-grained data on polar bear movements....

Lidar-based biomass and structure mapping in the Yukon River Basin

US Geological Survey (USGS) - Current climate predictions indicate that high northern latitude ecosystems will experience significant change over the next century and beyond. This is expected to have an impact on forest structure, including aboveground biomass (AGB), and therefore on the flux of carbon in the boreal forests that contribute to these ecosystems. Also, fire frequency and severity are both expected to increase,...
