Please note, the processing methods described use SIO-CalCOFI-developed software (DECODR & BtlVsCTD) to merge and correct Seabird 911+ CTD data with bottle samples. The Seasoft portion of our data processing protocol follow their recommended settings for our 911+ v2 CTD & deck unit. “Sta.csvs” are bottle data collected at each station cast combined with 1m binavg…

Setting up and using the ISUS with Seabird CTD 1). Connect the ISUS Analog Out port to a 6-pin CTD port – we use voltage channel 6 on a universal Y-cable, allowing pH to occupy channel 7.  Map that port in Seasave as user-polynomial; under the user-polynomial, enter: A0 = – 7.1168, A1 = 27.155. …

A Sea-Bird Electronics 911plus V2 CTD collects vertical profile data at every CalCOFI station. In addition to being a dual TCO (temperature, conductivity, and oxygen) system, the CTD also interfaces with a transmissometer, fluorometer, PAR/SPAR meters, altimeter, nitrate, and pH sensor. Connected to a shipboard data-acquisition computer through an electronically-conductive winch wire, sensor data are…
