Salinity Processes in the Upper Ocean Regional Study (SPURS)

A Rosette water sampler system that will be used during the Salinity Processes in the Upper Ocean Regional Study (SPURS) is seen onboard the Woods Hole Oceanographic Institution's research vessel Knorr on Tuesday, Sept. 4, 2012, in Woods Hole, Mass. Knorr is scheduled to depart for the NASA-sponsored expedition on Sept. 6 and will head into the North Atlantic's saltiest spot to get a detailed, 3-D picture of how salt content fluctuates in the ocean's upper layers and how these variations are related to shifts in rainfall patterns around the planet.
