SEARCH Activities Spreadsheet

The SEARCH Project Office, ARCUS, is in the process of creating a single SEARCH Project Catalog. The projects in the table below will eventually be incorporated into the new catalog database. These projects come from an initial project assessment, started by the Polar Science Center / Applied Physics Laboratory at the University of Washington. The table below is downloadable as an excel spreadsheet:

SEARCH Project Spreadsheet - Last Updated: 26 April 2005

Entries in the table have been categorized according to the eight activities identified in the SEARCH Implementation Strategy, and also according to nine types of activity. For each entry, an indication of relevance has been assigned, with 1 indicating highest relevance and 3 indicating lowest relevance. A key to areas of activities and activity types is available at the bottom of the page.
