Description

Bottle data from the ODF CTD carousel, GEOTRACES Arctic cruise HLY1502.
ODF CTD BOTTLE file name from the Scripps Oceanographic Data Facility (ODF): 20160119ODF

Note: 'FLAG_W' columns correspond to the WHP (WOCE Hydrographic Program) quality flag scheme.

Methods & Sampling

See the HLY1502 cruise report for more information on data acquisition.

Note: Repeating GEOTRC_SAMPNO indicate samples where multiple smaller sample bottles were used to collect water at the same depth.

Data Processing Description

Version history:
2019-11-25: version 5: changed incorrect LONGITUDE value of sample 11256 (from 180.033.0087 to 180.0000).

2019-07-29: version 4: removed all "placeholder" columns containing no data (-999 only). These columns were included in the original files from ODF to indicate the expected datasets. All data reported from the cruise can by found on the HLY1502 cruise page or on the U.S. Arctic GEOTRACES project page.

2016-09-01: version 3 (ODF file dated 2016-01-19); replaces v2015-10-09-ODF. Updates include:
1) Pressure offset applied
2) Additional polyfits applied to temperature and conductivity
3) Updated non-linear fits to oxygen sensors
4) Updated shore analysis bottles sampled census

BCO-DMO Processing:
- added conventional header with dataset name; PI name; version date;
- added cruise_id column;
- reformatted time as HHMM;
- changed all hyphen, paretheses in parameter names to underscores;
- 2019-07-29: removed all "placeholder" columns containing no data (-999 only); a list of the removed columns available as a tab-separated file: ODF_Bottle_20190729_removals.tsv
- 2019-11-25: version 5: changed incorrect LONGITUDE value of sample 11256 (from 180.033.0087 to 180.0000).

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

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

Niskin bottle

Supplied Name:

Supplied Description:

NIS: Niskins bottles sampled from the the 12-place 30 liter rosette.
GSNIS: Niskins bottles sampled from the 36-place 10 liter GO-SHIP rosette.

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.
