<div><p>The CTD rosette was provided by the Knorr Shipboard Science Support Group (SSSG) and was prepared for initial deployment by the SSSG representative on our cruise, Catie Graver. The system was a SBE9+ CTD with a depth limit of 6000m. The investigators used the dual SBE3T/SBE4C sensor system for temperature and conductivity. The rosette was also equipped with a SBE43 oxygen sensor, a Benthos/Datasonics PSA-916 altimeter, a Wet Labs FLNTURTD combination fluorometer and turbidity sensor, and a WetLabs C-star transmissometer (operating at a wavelength of 660 nm with a 25cm pathlength). For hydrocasts less than 1000m deep, the investigators attached a Biospherical Instruments QSP-200L4S underwater PAR sensor. This sensor was linked to a surface PAR sensor on the ship (QSR-240).</p></div>
Processed CTD data from all sensors mounted on rosette.

<div><p>After the cruise, Krista Longnecker used SBE Data Processing to convert the data files, filter the data, remove wild edits, and bin average the data into 1-m bins. These processed data were exported to MATLAB and the SBE43 oxygen data were calibrated based on the discrete water samples analyzed during the cruise by Evan Howard (WHOI). Fluorescence values from the WET Labs ECO-AFL/FL have been converted from volts to milligrams per cubic meter using calibration values from WETLabs. The chlorophyll concentrations have not been further calibrated with discrete samples.</p>
<p>BCO-DMO Processing Notes:<br />
- Parameter names were modified to conform with BCO-DMO naming conventions.<br />
- lat_start and lon_start were added by joining the data to the event log and matching on the unique event number.<br />
- Replaced 'NaN' and '-9.99E-29' with 'nd' to indicate 'no data'.</p></div>
