P16N-2015

A hydrographic survey was conducted in the Pacific Ocean aboard the NOAA ship Ronald H Brown from 10 April - 25 June 2015. A total of 207 rosette/CTD/LADCP stations were occupied on a transect running roughly along longitude 152°W. CTD casts extended to within 10 meters of the seafloor and up to 24 water samples were collected throughout the water column. CTDO (conductivity, temperature, pressure, oxygen), transmissometer, fluorometer, and LADCP (lowered acoustic Doppler current profiler) electronic data; rosette water samples; and underway shipboard ADCP and carbon dioxide (CO2) measurements were collected during the survey.
