Awards were announced in July and August 2009 for the Arctic System Science (ARCSS) Program's most recent solicitation, Changing Seasonality in the Arctic System (CSAS). NSF received 71 individual proposals in response to the solicitation, representing approximately $30 million in requested funding—40 awards totaling $14.3 million were made. More than 85% of the funding for the 17 projects was provided through funds from the American Recovery and Reinvestment Act. Information on these projects is listed below.

Awards were also recently announced for ARCSS research funded through the Arctic Research Opportunities solicitation. A total of 19 awards were made totaling $5.6 million—all of the funds for these awards were provided through the American Recovery and Reinvestment Act. Information on these projects appears in the next article, "2009 ARCSS Projects Funded through Arctic Research Opportunities Solicitation," and more information about the Arctic Research Opportunities solicitation is available at:

Other recent ARCSS activities include discussions with the Study of Environmental Arctic Change (SEARCH) Science Steering Committee about improved integration between ARCSS and SEARCH activities.
