Description

Hydrographic measurements from discrete water bottle samples collected at Hydrostation S located 25 km SE of Bermuda (32°10' N, 64°30' W). Measurements have been collected since 1955 at the Panulirus hydrographic stations and include salinity, temperature, sigma theta, oxygen, and dissolved oxygen anomaly.

Methods & Sampling

Dataset acquisition description

CTD profiling was introduced to the Panulirus project in October 1988 (station #643) and the methodology used for collection of CTD data and integrated water samples has been consistent with those used on the Bermuda Atlantic Time series Study (see Knap et al., 1997). Prior to using a CTD all samples were collected from Hydrocasts using Nisken bottles and reversing thermometers for temperature and thermometric depth. Further information on the data collection from 1954-1984 can be obtained in the Joint WHOI and BBSR data report Station S off Bermuda , Physical measurements 1954-1988 (WHOI contribution No. 6894).

Ship information:
- R/V Panulirus I (June 1954-May 1967)
- R/V Panulirus II(June 1967-December 1982)
- R/V Weatherbird I (Jan 1983 - September 1989)
- R/V Weatherbird II (October 1989 - February 2005)
- R/V Atlantic Explorer (May 2006 - Present)

Data Processing Description

Dataset Processing Description

Data was processed, evaluated, and flagged using the following Quality Flag definitions:

Bottle (Niskin or Go-Flo) quality flags: -3= suspect, 1= unverified, 2= verified/acceptable
Parameter data quality flags: 1= unverified, 2= verified acceptable, 3= questionable, 4= bad, 9= no data

Instruments

CTD Sea-Bird 911

Supplied Description:

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.

GO-FLO Bottle

Supplied Name: Go-FLo bottle

Supplied Description:

Go-Flo bottles are made by General Oceanics, and they allow water to flow through them once past the initial top layer of water, and up until they are triggered to close. The tubes are made of stout PVC that can be sent to depths of 500m or more.

Instrument Type

Generic Name: GO-FLO Bottle

Acronym: GO-FLO

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

GO-FLO bottle cast used to collect water samples for pigment, nutrient, plankton, etc. The GO-FLO sampling bottle is specially designed to avoid sample contamination at the surface, internal spring contamination, loss of sample on deck (internal seals), and exchange of water from different depths.

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.

Salinometer

Supplied Name: Guildline salinometer

Supplied Description:

Instrument Type

Generic Name: Salinometer

Generic Description:

A salinometer is a device designed to measure the salinity, or dissolved salt content, of a solution.
