Retrospective Study of Walrus Foraging and Movement Patterns During a Major Ecosystem Shift in the Bering and Chukchi Seas
|
North Pacific Research Board (NPRB)
-
Recent work suggests that anthropogenic climate change has caused a shift from arctic to subarctic conditions in the Bering Sea, which has resulted in replacement of ice-dominated benthic ecosystems with pelagic-dominated ecosystems. This has occurred in areas that support the largest breeding colonies of Pacific walrus (Odobenus rosmarus divergens). Some have hypothesized that this northward...

Sea-ice thickness measurement off Barrow
|
Alaska Ocean Observing System (AOOS)
-
At two locations off Barrow, ice thickness and velocity are measured along with water velocity profile, temperature and salinity. The nearshore site is within the footprint of the UAF sea-ice radar in Barrow. The offshore site is within a frequently occurring coastal polynya and its data will be used to validate estimate of thin ice thickness from satellite microwave sensor.

Extending marine mammal acoustic tracking ranges in the Beaufort Sea using a vertical array
|
North Pacific Research Board (NPRB)
-
The ability to localize marine mammal sounds is a key step in establishing population density estimations and evaluating subtle responses to anthropogenic activities. While numerous passive acoustic systems in the Arctic can detect marine mammal sounds, only a few systems localize biologic sounds, and require multiple deployments of widely separated instruments; a cumbersome, expensive process...

Assessing Arctic Sea Ice
|
US Geological Survey (USGS)

This project uses a variety of satellite remote sensing imagery and algorithms to study long-term changes and trends in Arctic sea ice. Arctic sea ice plays a significant role in Earth's climate system, and is critical habitat for numerous arctic marine mammal species. Decadal oscillations in Arctic atmospheric circulation have shown strong linkages with observational changes in sea ice...

One of BOEM’s target science interests is to learn more about the current spatial use patterns in the Beaufort Sea by potentially sensitive organisms, such as the epibenthics. Currently little is known about the epibenthic communities in the central Beaufort Sea. This proposed project is piggybacking an existing BOEM project that will characterize fish communities in the targeted area of the...

The Effect of Sea Ice Mobility on Shelf Basin Exchange in the Alaskan Beaufort Sea
|
North Pacific Research Board (NPRB)
-
The Alaskan Beaufort shelf (ABS) is fed by Pacific water emanating from Bering Strait and is strongly wind-forced in fall and winter due to the passage of synoptic storms. Because this Pacific derived water flowing along the northern boundary of the ABS is nutrient rich, upwelling of these Pacific waters onto the ABS is an important source of nutrients to the shelf. Thus understanding upwelling...

Because of its abundance, wide distribution and foundational ecosystem role, Arctic Cod (Boreogadus saida) is arguably the most important fish found in Arctic waters. This small gadoid fish which at times can be locally very abundant, is found as far south as Norton Sound in the Pacific and the Gulf of St. Lawrence in the Atlantic. In spite of the ecological importance and a possibility of...
