High primary productivity. Update on SPURS-2 (‘Fresh SPURS’) and SPURS-1 synthesis. Update from Dr. Eric Lindstrom. SPURS main question: What . is controlling the upper ocean . salinity?. Will . be addressed with interagency and international collaboration using measurements from satellites, ships, drifters, floats, gliders, AUVs and modeling.. Density Controls. Controlled by:. 1.) Temperature. 2.) Salinity. 3.) Pressure. Density increases with increasing salinity. Density increases with decreasing temperature.. Density increases with increasing pressure.. Actual Percentages.
