Overview

NASA's Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the Polar Regions with the global climate system. IceBridge uses a specialized fleet of aircraft and the most sophisticated suite of science instruments ever assembled to gather data on sea ice, glaciers, and ice sheets. The data gathered today will allow future scientists

What is it and why do we use it? A CTD — an acronym for Conductivity, Temperature, and Depth — is the primary tool for determining essential physical properties of sea water. It gives scientists a precise and comprehensive charting of the distribution and variation of water temperature, salinity, and density that helps to understand how the oceans affect life

What is it and why do we use it? An Acoustic Doppler Current Profiler, or Acoustic Doppler Profiler, is often referred to with the acronym ADCP. Scientists use the instrument to measure how fast water is moving across an entire water column. An ADCP anchored to the seafloor can measure current speed not just at the bottom, but also at

This short video from national geographic introduces viewers to the biology of a bowhead whale.

Arctic Ocean Biodiversity is a Census of Marine Life project aimed at coordinating research efforts examining the diversity in each of the three major realms: sea ice, water column and sea floor, including fish, mammals & birds. This program will consolidate what is known and fill remaining gaps in our knowledge: it leads the Arctic Ocean diversity cluster within the

NOAA Fisheries, Office of Protected Resources, provides information on bowhead whale status, taxonomy, species, description, habitat, distribution, population trends, threats, conservation efforts, regulatory overview, key documents, more info.

NOAA brochure on Alaska's bowhead whale's population, management, hunting, physiology and behavior.

Some movements and feeding patterns of the western Arctic stock of bowhead whales are poorly understood. The purpose of this project is to use satellite telemetry to identify feeding areas and migration corridors. This poster explains the details of the project.
