Wang, far right, and his students and lab members (clockwise from far left, Elliott Roberts, Kelly Knorr, Katherine Hoering, Sophie Chu, and Nick Tuttle) at sea around a CTD rosette. CTDs measure conductivity or salinity, temperature, and depth and are a common tool of oceanographic research. Water samples are collected in each of the rosette’s canisters at various depths and then chemically analyzed in the lab. (Photo by Taylor Crockford, Woods Hole Oceanographic Institution)
