Assessing ice seal abundance and sea-ice characteristics

National Oceanic and Atmospheric Administration (NOAA) - Use of UAS for assessment of both ice seal density and sea ice conditions. Refinement of techniques for automation of detecting & counting seals in large streams of digital photographs (also applicable to photos obtained from manned aircraft). 4 species of ice seals

Arctic coastal ecosystems: Evaluating the functional role and connectivity of lagoon and nearshore habitats

North Pacific Research Board (NPRB) - Recent research efforts aimed at understanding the marine ecosystem in the US Arctic have overlooked the barrier-island lagoon and nearshore systems. Despite this area’s importance for subsistence fisheries and as foraging habitat for protected marine mammals and seabirds it’s contribution to Arctic productivity is unknown. Further, it is unwise to assume that Arctic barrier island systems...

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.

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...

Bering-Aleutian salmon international survey (BASIS): Chukchi Sea Survey

National Oceanic and Atmospheric Administration (NOAA) - Study the effects of climate change (loss of sea ice) on the oceanography and pelagic/benthic fish communities. No survey planned in 2010; hopes for survey in 2011
