Salinity Working Group Meetings

US CLIVAR Salinity Workshop
8-10 May 2006
Woods Hole Oceanographic Institution

The salinity field of the global oceans is attracting increasing attention, due to its influence on ocean-atmosphere exchanges, its role as an indicator of the water cycle and its potential for improved climate forecasting. New sources of salinity data are now available (The Argo Project profiling float array: http://www.argo.ucsd.edu/) and others are on the horizon (The Aquarius satellite mission to be launched in March 2009 will measure sea surface salinity: http://aquarius.gsfc.nasa.gov ).

All investigators (PIs, post-docs and students) working toward the understanding of the regional and global processes linked to the variability and trends of salinity in the coupled climate system were invited. Also those able to address the technical challenges of long-term salinity measurements were invited to attend. The goal of the workshop was to produce a “white paper” articulating the significance of salinity measurements to the advancement of understanding, and ultimately predicting, climate; outlining the necessary measurements; and describing additional activities to enable the full utilization of these measurements. To this end the meeting forma entailed invited presentations, and an emphasis on group discussions, with poster space available to all attendees.

The Workshop was held in the Redfield Auditorium of the Woods Hole Oceanographic Institution, May 8-10, 2006. It was followed immediately by the Aquarius/SAC-D Third Science Workshop (May 10-12), given the strong connection between the workshop goals and the satellite mission's surface salinity measurement capabilities.
