The Polar Science Center Hydrographic Climatology (PHC) merges the 1998 version of the World Ocean Atlas (Antonov et al., 1998; Boyer et al., 1998) with the regional Arctic Ocean Atlas (EWG, 1997; 1998) creating a global climatology for temperature and salinity that contains a good description of the Arctic Ocean and its environs.

Polar Science Weekend is four days of hands-on activities, live demonstrations and exhibits presented by scientists who work in some of the most remote and challenging places on earth.  Polar Science Weekend is supported by a generous grant from NASA.

The focus of this project is to synthesize existing studies and data relating to Arctic Ocean primary production and its changing physical controls such as light, nutrients, and stratification, and to use this synthesis to better understand how primary production varies in time and space and as a function of climate change.

Significant changes in arctic climate have been detected in recent years. One of the most striking changes is the decline of sea ice concurrent with changes in atmospheric circulation and increased surface air temperature.

Through this project, investigators will characterize the seasonal linkages between the land surface greenness and a suite of land, atmosphere, and ocean characteristics, focusing on the Beringia/ Beaufort Sea, where there have been strong positive increases in the Normalized Difference Vegetation Index (NDVI) over the past 25 years, and the west-central Arctic Eurasia region, where the NDVI trends have been slightly negative.
