Depth, temperature, oxygen, salinity, and fluorescence from 0-4500m depth CTD profiles conducted during the R/V Kilo Moana cruise KM1427 in the North Pacific Ocean in December of 2014

Abstract:

CTD profiles were conducted during the R/V Kilo Moana cruise KM1427 in the North Pacific Ocean in December of 2014. Profiles ranging from 0-4500 meters measured depth, temperature, oxygen, salinity, and fluorescence.

Methods & Sampling

Samples were collected using a CTD rosette with Niskin bottles and immediately transferred into acid rinsed carboys (20 L). Samples were then filtered through a 0.2 um maxi capsule filter (Pall Corporation) prior to the acquisition of measurements.

For more information see Cartisano et al., 2018.

Data Processing Description

These data were analyzed with the software available on board the research vessel (software: Seasave v7.22.5). The data were then exported into Excel for further analysis.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* rounded depth to four decimal places. It was between 5-9 decimal places long.

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: SBE 911plus / 917plus CTD

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

Fluorometer

Supplied Name: WET Labs ECO-AFL/FL

Supplied Description:

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.
