Description

CTD data from cruises BIP XII, Shana Rae 2013, and MBB Soledad 2014.

Methods & Sampling

Dataset acquisition description

Data were collected with Seabird SBE19plusV2 (SN 01906222) equipped with the following sensors:
Temperature: ITS-90
Pressure: Strain Gauge
Oxygen:SBE43
Fluorescence: WET Labs ECO-AFL/FL

All sensors (except Fluorescence) are calibrated annually by Seabird Electronics, Inc.

Data Processing Description

Dataset Processing Description

Data were processed by hand to remove unreliable measurements during the initial period of sensor stabilization at the surface before the cast (2 minutes). Binning to 1 m depth bins for the downcast was carried out during conversion from .hex files to ascii text (.cnv) files using the most current .con file provided by Seabird Electronics at the time of annual calibration.

BCO-DMO data processing:
- Re-formatted date and time.
- Replaced commas with semi-colons.
- Replaced blanks with "nd" to indicate "no data".
- Replaced spaces with underscores.
- Changed lon in positive degrees W to negative degrees E.
- Modified parameter names to conform with BCO-DMO naming conventions.

CTD Sea-Bird SBE SEACAT 19plus

Supplied Name: Seabird SBE19plusV2

Supplied Description:

Data were collected with Seabird SBE19plusV2 (SN 01906222).

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.
