Description

Methods & Sampling

Dataset acquisition description

CTD casts were conducted on R/V Sally Ride cruise, SR1805. Two different rostte/CTD systems for were used for the casts. Casts CTD2, -24-26, -62-69 and -103-108 were done with a 24-place rosette with 10L Niskins. All the other casts were done with a 12-place rosette and 30-L Niskins. Both rosettes deployed a Sea-Bird SBE 9 CTD.

Known Problems/Issues:
For casts CTD29, -62, -62.b, -65, -68, -107, the date and time data were wrong. The CTD automatically reset to January 01 2000 and we did not catch this every time. These incorrect dates and times have been replaced with 'nd' (no data) in this dataset. The elapsed times are correct, and the true date, an approximate time of each cast, can be found in the overall event file for this cruise (see Supplemental Files).

Data Processing Description

Dataset Processing Description

CTD data were processed with Seasave V7.26.7.107.

BCO-DMO Processing:
- renamed fields to comply with BCO-DMO naming conventions;
- replaced incorrect dates and times with "nd" (no data);
- changed date format to YYYY-MM-DD;
- created ISO8601 date/time field (UTC).

Instruments

CTD Sea-Bird 9

Supplied Name: Sea-Bird SBE 9 CTD

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 Name: 10L Niskins and 30L Niskins

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.
