Methods & Sampling

The IFCB (Image Flow CytoBot) sampling occurred on February 8 and March 7 2020 at three stations over Palmer Deep Canyon (see Hudson et al., 2021 for station locations). Water samples for the IFCB were collected with a SeaBird SBE-19 Plus V2 CTD and 6 Niskin bottles, which fired at 5, 35, 75, 100, 150, and 200 m on the upcasts.

Sampling was done at 3 stations over Palmer Deep Canyon, with H5 being over the canyon and H1 as the most inshore station.

Data Processing Description

CTD data files were processed using the read.ctd function in the R oce package. Only the downcasts were considered.

Supplied Name: SeaBird SBE-19 Plus V2 CTD

Supplied Description:

SeaBird SBE-19 Plus V2 CTD, factory calibrated July 2019, SN 156.

Instrument Type

Generic Name: CTD Sea-Bird SBE SEACAT 19plus

Acronym: Sea-Bird SEACAT 19 Plus

Generic Description:

Self contained self powered CTD profiler. Measures conductivity, temperature and pressure in both profiling (samples at 4 scans/sec) and moored (sample rates of once every 5 seconds to once every 9 hours) mode. Available in plastic or titanium housing with depth ranges of 600m and 7000m respectively. Minature submersible pump provides water to conductivity cell.
