Methods & Sampling

CTD casts were performed using the ships CTD rosette every 4 hours to survey the water column down to a depth of 500 meters.

The CTD used for this study had redundant/ replicate sensors for measuring many of the parameters.

Data Processing Description

The data is converted from its raw form using the “convert” program in the SBEDataProcessing software. The data then got binned based on depth with a bin size of 1 using the “Bin Average” program within the same software suite. BCO-DMO processing notes: * Did not serve cast InVirTC1 (test cast) * Removed PAR and SPAR columns due to uncertain values * Renamed fields to comply with database requirements * Joined CTD files with dates
