Description

CTD hydrography data from bottle casts on the MV1008 cruise in the Costa Rica Dome (CRD) region of the Eastern Tropical Pacific Ocean.

These bottle hydrography data correspond to samples collected for chl-a, nutrients, and microbial populations from flow cytometry and epifluorescence microscopy.

Methods & Sampling

Dataset acquisition description

Sampling instruments consisted of a Sea-Bird Electronics SBE9plus CTD with dual pumps (SBE5), dual temperature (SBE3plus), reference temperature (SBE35RT), dual conductivity (SBE4C), dissolved oxygen (SBE43), transmissometer (Wetlabs), fluorometer (Wetlabs CDOM), and PAR sensor (Biospherical).

Data Processing Description

Dataset Processing Description

BCO-DMO assumes dates provided are in local time, based on comparing cast events to the MV1008 event log.

Instruments

CTD Sea-Bird 9

Supplied Name: CTD SBE 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.

Sea-Bird SBE 43 Dissolved Oxygen Sensor

Supplied Name: SBE43

Supplied Description:

The SBE9plus CTD contained an SBE43 dissolved oxygen sensor.

Instrument Type

Generic Name: Sea-Bird SBE 43 Dissolved Oxygen Sensor

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

Sea-Bird SBE-3 Temperature Sensor

Supplied Name: SBE3

Supplied Description:

The SBE9plus CTD contained dual SBE3plus temperature sensors.

Instrument Type

Generic Name: Sea-Bird SBE-3 Temperature Sensor

Acronym: SBE-3 Temperature

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

The SBE-3 is a slow response, frequency output temperature sensor manufactured by Sea-Bird Electronics, Inc. (Bellevue, Washington, USA). It has an initial accuracy of +/- 0.001 degrees Celsius with a stability of +/- 0.002 degrees Celsius per year and measures seawater temperature in the range of -5.0 to +35 degrees Celsius. more information from Sea-Bird Electronics

Sea-Bird SBE-4 Conductivity Sensor

Supplied Name: SBE4C

Supplied Description:

The SBE9plus CTD contained dual SBE4C conductivity sensors.

Instrument Type

Generic Name: Sea-Bird SBE-4 Conductivity Sensor

Acronym: SBE-4 Conductivity

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0417/

Generic Description:

The Sea-Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter. The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops. The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes. Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.
