Methods & Sampling

Standard hydrographic measurements of temperature, salinity, oxygen, and chlorophyll (Chl) fluorescence were made using a Seabird SBE 911 conductivity-temperature-depth (CTD) unit combined with a fluorometer and an oxygen sensor mounted to a rosette sampler equipped with 12 ten-liter Teflon-coated Niskin bottles during a cruise from August 6 to 16, 2016, aboard the R/V Hugh R. Sharp.

Instruments

CTD Sea-Bird 911

Supplied Name: Seabird 911 CTD

Supplied Description:

Standard hydrographic measurements of temperature, salinity, oxygen, and chlorophyll (Chl) fluorescence were made using a Seabird SBE 911 conductivity-temperature-depth (CTD) unit.

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.

Fluorometer

Supplied Name: Fluorometer (ECO-AFL/FL, WET Labs)

Supplied Description:

Fluorescence measurements were made using a Seabird SBE 911 conductivity-temperature-depth (CTD) unit combined with a fluorometer and an oxygen sensor mounted to a rosette sampler.

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.

Oxygen Sensor

Supplied Name: Oxygen sensor

Supplied Description:

Oxygen measurements were made using a Seabird SBE 911 conductivity-temperature-depth (CTD) unit combined with a fluorometer and oxygen sensor mounted to a rosette sampler.

Instrument Type

Generic Name: Oxygen Sensor

Acronym: Dissolved Oxygen Sensor

Generic Description:

An electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed
