Description

AE1918 was a cruise of opportunity on which two oceanographic sampling activities were conducted: a CTD cast and a MOCNESS net tow. These are the processed, binned CTD data.

Methods & Sampling

Dataset acquisition description

The CTD was run using standard operating procedures. Bottles were triggered to check for reliability of the system within the NSF inspection procedure, not for science. Bottle file then not included.

Data Processing Description

Dataset Processing Description

Data was processed with provided config file (AE1918C1.XMLCON). Data was processed (included all data) and then binned in 1 m intervals using SBEDataProcessing software.

BCO-DMO Processing:
- added parameter names (using names from file header).

Instruments

CTD Sea-Bird 911

Supplied Name:

Supplied Description:

Seabird 9/11 unit attached to a 24 bottle rosette

Instrument Type

Generic Name: CTD Sea-Bird 911

Acronym: CTD SBE 911

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0035/

Generic Description:

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). More information from Sea-Bird Electronics.
