Description

Methods & Sampling

Dataset acquisition description

Standard station CTD profiles were conducted (down casts) with water sampling conducted during the up casts.

This dataset is comprised of the down cast data from station numbers 1-118, except for stations #2 and #100 in which the down casts failed, and thus the upcast data are included instead. Note the CTD fluorescence and oxygen data have not been adjusted using the bottle data for chlorophyll and oxygen as a calibration in the final CTD data.

Please disregard station #51 primary oxygen profiles - both voltage and ml/L measurements. This was a single cast test comparison, and measurements were taken from another sensor.

Data Processing Description

Dataset Processing Description

Data were processed using the Sea-Bird Software SBE Data Processing, version 7.21k. Data acquisition used SBE Seasave, version 7.14e.

CTD Sea-Bird SBE 911plus

Supplied Name: CTD Sea-Bird 911

Supplied Description:

SeaBird 911+ Rosette 24-position, 10-liter bottle Rosette with dual T/C sensors At each station, CTD casts measured temperature, salinity and PAR. Water samples collected at depths of 500, 300, 250, 200, 150, 120, 100, 80, 60, 40, 30, 20, 10 m, and the surface were filtered, processed or preserved for further analysis.

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

Acronym: SBE-43 DO

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0036/

Generic Description:

The Sea-Bird SBE 43 dissolved oxygen sensor is a redesign of the Clark polarographic membrane type of dissolved oxygen sensors. more information from Sea-Bird Electronics

Wet Labs ECO-AFL/FL Fluorometer

Supplied Description:

Instrument Type

Generic Name: Wet Labs ECO-AFL/FL Fluorometer

Acronym: ECO AFL/FL

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0172/

Generic Description:

The Environmental Characterization Optics (ECO) series of single channel fluorometers delivers both high resolution and wide ranges across the entire line of parameters using 14 bit digital processing. The ECO series excels in biological monitoring and dye trace studies. The potted optics block results in long term stability of the instrument and the optional anti-biofouling technology delivers truly long term field measurements.
