Description

Bottle data from CTD rosettes deployed on the WS1010 and AT18-02 cruises in the Gulf of Mexico.

Methods & Sampling

Dataset acquisition description

CTD casts in the vicinity of the Macondo Wellhead were complicated by the presence of oil on the sea surface. A saltwater hose was used to spray the sea surface, parting the oil to create a clean area for the CTD to be dropped through; a similar procedure was used for deployment and recovery.

Data Processing Description

Dataset Processing Description

WS1010 bottle data was processed using Seasave software v. 7.18.
AT18-02 bottle data was processed using Seasave software v. 7.20f.

Parameter names have been changed to conform with BCO-DMO conventions. month_utc, day_utc, lat_start, and lon_start were added from the header information in the original bottle data files.

BCO-DMO made the assumption that the WS1010 file named '6.01' was actually for cast '6.02' and the file named '16.01' was actually cast '16.02', based on the dates and station numbers in the headers of those files. It was also assumed that the AT18-02 file named '12.04' was actually for cast '12.05' based on the event log.

Instruments

CTD Sea-Bird 9

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird 9

Acronym: CTD SBE 9

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

The Sea-Bird SBE 9 is a type of CTD instrument package. The SBE 9 is the Underwater Unit and is most often combined with the SBE 11 Deck Unit (for real-time readout using conductive wire) when deployed from a research 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, fluorometer, altimeter, etc.). Note that in most cases, it is more accurate to specify SBE 911 than SBE 9 since it is likely a SBE 11 deck unit was used. more information from Sea-Bird Electronics

Niskin bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
