Supporting documentation:


Operations Area: Eastern North Atlantic

Lat/Lon: 25° 0.0′ N / 38° 0.0′ W

Depth Range: 2000 / 5800m

Will the vessel be operating within 200 NM of a foreign country? none
Are visas or special travel documents required? no

Science objectives

SPURS (Salinity Processes Upper-ocean Regional Study) is designed to improve our understanding of how the salinity maximum of the North Atlantic is maintained.  A variety of autonomous instruments will be deployed along with three moorings, and hydrographic and microstructure surveys performed.

Science Activities

Deploy three surface moorings in the North Atlantic salinity maximum at 25N, 38 W.  Deploy floats, gliders and other AUV's.  Perfom microstructure and mixing measurements with free profilers.  Perform CTD casts and log underway thermosalinograph data in the region of teh surface salinity maximum.

Pre-cruise planning meeting: Visit WHOI

Media personnel on board: Scientists will maintain a blog
