Methods & Sampling

Dataset acquisition description

Samples were collected onboard the R/V Kilo Moana between 8/7 and 9/5 2013. Water property data were collected using a Niskin rosette equipped with a Seabird CTD package and auxiliary sensors, specifically: Seabird 911 CTD, SBE 43 Dissolved Oxygen Sensor, Biospherical/Licor PAR/Irradiance Sensor, WETLabs ECO Chlorophyll Fluorometer, WETLabs C-Star Transmissometer, Seapoint Chlorophyll Fluorometer. Discrete samples for nutrients, oxygen, and prokaryotic cells were collected using a Niskin rosette attached to the sensor package. All CTD sensors were factory calibrated within 1 year of deployment. Nutrient samples were filtered onboard, frozen immediately at -80 degrees C, and subsequently processed at the University of Washington Marine Chemistry Lab using the US-JGOFS protocols. Discrete oxygen samples were analyzed on board using the Carpenter modification of the Winkler method. The bottle data includes the CTD data from each Niskin event, as well as nutrients, oxygen, and prokaryotic cells.

CTD Sea-Bird SBE 911plus

Supplied Name: CTD SBE 911plus

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

Instrument Type

Generic Name: CTD-fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

A CTD-fluorometer is an instrument package designed to measure hydrographic information (pressure, temperature and conductivity) and chlorophyll fluorescence.

Fluorometer

Supplied Description:

Seapoint Chlorophyll Fluorometer

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.

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.

Photosynthetically Available Radiation Sensor

Supplied Name: PAR sensor

Supplied Description:

Biospherical/Licor PAR/Irradiance Sensor

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

Generic Description:

A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.
