Arctic Whale Ecology Study (ARCWEST)
Use passive acoustics, oceanography, satellite tagging, and visual surveys to investigate the source of cetacean prey and its influence on distribution and abundance. Focusing... -
Arctic Fish Ecology Catalogue (AK-07)
The marine fishes in waters of the United States north of the Bering Strait have received new and increased scientific attention over the past decade in conjunction with... -
Chukchi Offshore Monitoring in Drilling Area (COMIDA)
The November 2006 COMIDA workshop described the importance of benthos and chemical monitoring to evaluate the health of the Chukchi ecosystem. The BOEM Scientific Committee (SC)... -
Surface Current Circulation High Frequency (HF) Radar Mapping in the Chukchi Sea (AK-09-06)
The shallow (50 m) Chukchi shelf extends 800 km northward from Bering Strait to the shelfbreak along the 200 m isobath. The Chukchi Sea flow field is influenced by the winds;... -
Epifaunal Communities in the Central Beaufort Sea (AK-08-12-07)
There is a growing need to increase our understanding of the species composition, abundance and biomass across the Alaskan Beaufort Sea shelf. This stems from a severe lack of... -
Satellite-Tracked Drifter Measurements in the Northeast Chukchi Sea (AK-08-12-08)
This study was initiated to better understand the surface circulation in the Chukchi Sea, which is not well-measured by subsurface moorings. The overall goal of this program was... -
Abundance Estimates of Ice-Associated Seals: Bering Sea Populations that Inhabit the Chukchi Sea (AK-12-x10b)
Aerial surveys were conducted in spring 2012 and 2013. In the United States and Russia combined, more than 47,000 nautical miles (nmi) (87,000 km) of survey track was flown. The... -
Trophic Links: Forage Fish, Their Prey, and Ice Seals in the Northeast Chukchi Sea (AK-08-12-05)
The goal of this research was to examine the feeding ecology of Arctic fishes and ice seals in the Northern Chukchi Sea to provide a baseline for assessing how trophic structure... -
Aggregate Effects Research and Environmental Mitigation Monitoring of Oil Industry Operations in the Vicinity of Nuiqsut (AK-08)
Over the years, agencies, industry, and local residents have adopted measures from documented studies or worked to develop new mitigation measures intended to lessen the impacts... -
Migration and Habitat Use by Threatened Spectacled Eiders in the Eastern Chukchi Near and Offshore Environment (AK-09-03)
Spectacled Eiders (Somateria fischeri) are sea ducks that spend 9 to 12 months of the year in marine habitats of the East Siberian, Chukchi, Beaufort, and Bering seas where sea... -
Chukchi Offshore Monitoring in Drilling Area (COMIDA): Factors Affecting the Distribution and Relative Abundance of Endangered Whales and Other Marine Mammals in the Chukchi Sea
The Chukchi Sea shelf is a bathymetrically complex region where air-sea-ice interactions govern ecosystem structure and function. CHAOZ used a combination of autonomous moored... -
Dispersal Patterns and Summer Ocean Distribution of Adult Dolly Varden from the Wulik River, Alaska, Evaluated Using Satellite Telemetry (AK-08-12)
In northwest Alaska near the Chukchi Sea, Dolly Varden charr Salvelinus malma is highly valued as a subsistence fish and local residents harvest thousands of these fish each... -
Chukchi Sea Environmental Studies Program: Seabirds
The seabird ecology component collects data on the distribution and abundance of seabirds in the northeastern Chukchi Sea in the vicinity of several oil and gas lease areas and... -
Chukchi Sea Environmental Studies Program: Acoustic Buoy
The acoustics monitoring program is designed to measure underwater ambient and industrial noise levels, and to detect and classify species of vocalizing marine mammals over a... -
Gas Hydrate Dynamics on the Alaskan Beaufort Continental Slope: Modeling and Field Characterization
The goal of this research is to assess the contemporary state of the upper continental slope in the Alaskan Beaufort Sea to determine if gas hydrates are in equilibrium with... -
Dispersant in Ice
Chemical dispersants enhance natural dispersion by reducing the surface tension at the oil/water interface, making it easier for waves to create small oil droplets (generally... -
Marine Mammal Monitoring
Objectives: Determine species composition, temporal and spatial abundance, density and distribution of marine mammals in the Klondike and Burger areas. Also identify important... -
Synthesis of Arctic Research
Our goal is to increase scientific understanding of the relationships among oceanographic conditions, benthic organisms, lower trophic prey species (forage fish and... -
Chukchi Sea Physical Oceanographic Measurements
The objective of this task is to describe spatial and seasonal charcteristics of the water masses and circulation in the two study areas (Klondike and Burger prospects).
