US GEOTRACES will hold a workshop to define the scientific objectives of a cruise in the western Arctic Ocean, tentatively planned for late summer 2015. Investigators interested in conducting research as part of this cruise are invited to attend the workshop, which will take place 13-15 June 2012 at the National Science Foundation. No prior involvement in GEOTRACES is necessary to participate in this workshop.
A framework for planning this cruise is provided in two reports from previous Arctic GEOTRACES planning workshops, posted online at: (http://www.geotraces.org/libraries/documents/Arctic_Report.pdf) and at (http://www.usgeotraces.com/documents/arcticDOC/ArcticWorkshopRpt.pdf).
The purpose of this workshop is to refine the research objectives for the cruise and to devise a strategy to meet those objectives. Members of the US GEOTRACES Scientific Steering Committee (SSC) will participate in the workshop. They will synthesize results from the deliberations and prepare a set of priorities to guide the submission (tentatively 15 February 2014) and evaluation of proposals. The overriding criterion for establishing priorities is the degree to which an activity will enable US scientists to achieve the goals of GEOTRACES as defined in the Science Plan (http://www.geotraces.org/science/science-plan).
The Science Plan defines a number of key TEIs that must be measured on every section. It also identifies a number of complementary parameters that would be desirable. These include other TEIs that are of interest in their own right, for example in illuminating specific processes of interest, or parameters that may be critical for interpreting the distributions of key TEIs (e.g., circulation tracers). The SSC will consider these factors when establishing priorities for the section.
In preparation for the workshop, the SSC requests that those interested in participating submit a brief (one page maximum) statement of interest by 6 April 2012. Statements should (a) define the nature of the work to be done on the cruise, and (b) justify the work in terms of GEOTRACES objectives. Statements can be emailed (preferably as Word documents) to <email@example.com>. Statements will be posted on the US GEOTRACES web site unless the author requests that they be held in confidence.
Although no prior involvement in GEOTRACES is necessary to participate in the Arctic section, new investigators who have not participated in the GEOTRACES intercalibration exercise are obliged to follow the GEOTRACES policy for new investigators. This involves analysis of GEOTRACES reference standards, where applicable, or collection of duplicate samples for analysis by labs that have already demonstrated acceptable performance in the GEOTRACES intercalibration. This policy will be explained at the workshop.
Workshop travel expenses will be subsidized by the US GEOTRACES project office. The project office budget will cover full travel expenses for approximately 45 participants. However, the SSC prefers to limit the level of travel reimbursement rather than limit the number of participants. Therefore, the level of reimbursement may have to be limited if the number of participants exceeds approximately 45.
REMINDER: DEADLINE is 6 April 2012 to submit a statement of interest and a request for reimbursement of travel expenses to participate in the workshop.

Since the inception of the international GEOTRACES Program, a strong interest has developed in carrying out GEOTRACES-related activities in the Arctic Ocean. The Arctic Ocean is at the epi-center of climate change, and changes there will ultimately be felt globally. It constitutes less than 3% of the World Ocean area and about 1% of the volume, but it is unique in several ways. About 10% of the global river run-off is delivered to the Arctic Ocean and about 30% of the world's soil carbon is estimated to be stored in northern ecosystems within the Arctic catchment area. Effects due to a warming climate may have profound impact on the Arctic resulting in increased export of organic carbon and sediments to the Arctic Ocean. Arctic shelves constitute about 25% of the World Ocean shelf area and are among the shallowest in the world acting as an important regulator of the river export of organic carbon and TEIs to the central Arctic Ocean.
This interest has already led to several discussions and deliberations, including a GEOTRACES planning meeting held in Delmenhorst, Germany in June 2009 which recognized the need for international collaboration to make future GEOTRACES efforts viable in this region.
In order to focus these discussions and to generate an action plan for future GEOTRACES activities between US investigators and international collaborators, a U.S. GEOTRACES Arctic Planning Workshop will take place from September 29 to October 1, 2010 in Washington D.C.
