Dataset-specific description

Transmissometer - WET Labs C-Star

SIOR/30L-Niskin Rosette/CTD casts were performed with a package consisting of a 12-bottle rosette
frame (SIO/STS), a 24-place carousel (SBE32) and 12 30L General Oceanics bottles with an absolute
volume of 30L each. Underwater electronic components consisted of a Sea-Bird Electronics SBE9plus
CTD with dual pumps (SBE5), dual temperature (SBE3plus), reference temperature (SBE35RT) dual
conductivity (SBE4C), dissolved oxygen (SBE43), transmissometer (WET Labs C-Star), fluorometer
(Seapoint SCF) and altimeter (Tritech LPRA-200 or Simrad 807). A second dissolved oxygen plus oxygen
temperature sensor (JFE Advantech RINKO-III) was incorporated into the data stream for future sensor
evaluation; it was not processed for this cruise
