APL-UW has produced a video about Polar Science Weekend, an annual public outreach event centering around polar research. Watch APL-UW scientists, including veteran PSW participants PSC’s Ben Smith and Wendy Ermold, explain their research in ways that apply the principles of physics via hands-on activities to the community.
Recent years have seen extreme changes in the Arctic sea ice cover and adjacent open ocean – reduced ice extent, record sea surface temperatures, thinner and younger ice, and loss of ice in areas that had been ice-covered throughout human memory.Particularly striking are changes within marginal ice zones (MIZ) – areas that are becoming increasingly covered by low concentration, diffuse sea ice.The proposed work, referred to here as the “Marginal Ice Zone Ocean and Ice Observations and Processes Experiment (MIZOPEX)”, brings to bear the capabilities of unmanned aircraft systems (UAS) in concert with in-situ observations and satellite remote sensing to…

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.

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.

This project supports the design, development, and implementation of a component of an Arctic Ocean Observing System in the Switchyard region of the Arctic Ocean (north of Greenland and Nares Strait) that serves the scientific studies developed for the IPY (International Polar Year), SEARCH (Study of Environmental ARctic Change), and related programs.
