Postdoctoral scholar Liz Douglass (left) and chief scientist Ruth Curry recover a CTD  rosette during a cruise aboard RV Knorr in the North Atlantic in 2011. The cruise was part of the DynaMITE program investigating how cold, dense waters from the Antarctic mix with warmer, more buoyant waters and drive circulation throughout the North Atlantic basin. Rosette samplers like this one are used to measure conductivity (salinity), temperature, and depth (pressure) in the water column and to retrieve samples of water from various depths.(Photo by Carolina Nobre, Woods Hole Oceanographic Institution)
