Details onstation location in PIB are shown in Fig. 2During NBP0901, 160 CTD casts measuring Conductivity, Temperature and Depth were made with the Sea-Bird SBE 9/11+ system on a 24 bottle SBE32 rosette in support of the O-274, B-244, and O-261 projects.Temperature, conductivity, and dissolved oxygen were measured with dual sensor systems, primary andsecondary. The sensors and pumps were mounted vertically on a horizontal frame connected to the rosetteframe near the bottom. A single pressure sensor, rated to 6,000 dbar (10,000 psia), provided pressureinformation for conversion to depth. Additionally, single chlorophyll fluorometer, transmissometer, andPAR sensors were attached to the rosette in support of the DynaLife operations (B-244).
