Phosphorus Distribution and Partitioning In the Chukchi Sea During Summer 2010
<p>Water column samples from the Chukchi Sea were collected during June-July 2010 as part of the NASA ICESCAPE (Impact of Climate Change on the Eco-Systems and Chemistry of the Arctic Pacific Environment1.34) mission to study phosphorus (P) partitioning and distribution. Our results indicate that P …

Lipid Biomarkers of Bering and Chukchi Sea Euphausiids and Their Application to Diet History
<p>In the eastern Bering Sea, <em>Thysanoessa raschii</em> are the most abundant krill species and a keystone trophic member that serve as both an important grazer and link to upper level consumers. In this system krill experience large annual variation in food resources, especially during ice …

Physical control of the distributions of a key Arctic copepod in the northeast Chukchi Sea
… important zooplankton taxa in the Arctic shelf seas where it serves as a key grazer, predator, and food source. Its summer distribution and abundance have direct effects on much of the food web, from blooming phytoplankton to migrating bowhead whales. The Chukchi Sea represents a highly …

Interannual variability of the Pacific Water boundary current in the Beaufort Sea
… Water boundary current in the Alaskan Beaufort Sea near 152° W. Using velocity and hydrographic data from six year-long deployments during this time period, we examine the interannual variability of the current. It is found that the volume, heat, and freshwater transport have all decreased …

Coupling Metaproteomics with Taxonomy to Determine Responses of Bacterioplankton to Organic Perturbations in the Western Arctic Ocean
… within the shallow shelf ecosystem of the Chukchi Sea after rapid fluctuations in algal organic matter availability. Novel bioinformatics tools were collaboratively developed and used together with community proteomics (metaproteomics) to characterize and quantify changes in bacterial …

Examining Melt Pond Dynamics and Light Availability in the Arctic Ocean via High Resolution Satellite Imagery
… light availability are the primary drivers for seasonal progression of water column primary production and warming. Observations of melt pond development and distribution require meter scale resolution and have traditionally been limited to airborne images. However, recent advances in high …

Bio-Optical Properties of the Arctic Waters: Empirical and Theoretical Observations
… were made during August 2000 in the Beaufort and Chukchi Seas. Chlorophyll <em>a</em> concentration (Chl) ranged from 0.068 to 18.51 mg chl m<sup>−3</sup>. Both total particulate and phytoplankton absorption at 443 nm were closely correlated with chlorophyll concentration. There is no strong …

Un-mixing the Ocean: Double Diffusion and Turbulence in Polar Oceans
… observational turbulence data collected in the Chukchi Sea in the marginal seas of the Arctic Ocean. This data shows an oceanographic section of a warm core intrahalocline eddy, where thermohaline layering was observed. We develop a criterion to predict the observed turbulent dissipation rates …

Ocean Tides Modeling using Satellite Altimetry
… interactions between ocean, atmosphere, and sea ice, dissipate their energy in the ocean and solid Earth, and decelerate the Moon’s mean motion. Oceanographic studies and applications, including coastal or continental shelf ocean circulations, also require observations to be ‘de-tided’ using …

Changes in shelf waters due to air-sea fluxes and their influence on the Arctic Ocean circulation as simulated in the OCCAM global ocean model
… that buoyancy fluxes that occur due to air-sea exchanges on the continental shelves are an important driving force for the boundary current in the model.<br/>The formation area of the circumpolar boundary current is found in the Barents Sea, where there is a high pressure area associated …
