CTD profiles from 2012 to 2019 in the Gulf of Maine

Abstract:

CTD profiles from 2012 to 2019 in the Gulf of Maine.

Expand/Collapse All

Acquisition Description

Sea-Bird SBE 9 CTD data measurements using Sea-Bird Software SBE Seasave at standard CTD stations: profiles (down casts) with water sampling (up casts).

Processing Description

Sea-Bird Software SBE Data Processing. All CTD profiles have been binned using 1db pressure bin.

Station numbers ending with .2 are station named with with "a" at the end (usually this is second cast at the same location when primary cast failed for some reason).

BCO-DMO Processing notes:

Adjusted station numbers (everything ending with .0 to integer) to join with location file
Concatenated all ctd files, added file names as Cruise IDs
Adjusted headers to comply with database requirements
Rounded fields to 3 and 4 decimales
Converted dates to ISO format

CTD Sea-Bird SBE 911plus

Supplied Name: SeaBird 911+ Rosette 24-position, 10-liter bottle Rosette with dual T/C sensors

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 300, 250, 200, 150, 120, 100, 80, 60, 40, 30, 20, 10 m, and the surface were filtered and preserved for nutrient 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 911plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911plus 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 9plus and SBE 11plus is called a SBE 911plus. The SBE 9plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3plus and SBE 4). The SBE 9plus 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

Generic Name: Seapoint Turbidity Meter

Acronym: Seapoint Turbidity

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0104/

WETStar CDOM Fluorometer

Supplied Name: WET Labs WETstar Fluorometer

Supplied Description:

These low cost, low power optical sensors provide comparable performance to other fluorometers at a fraction of their cost, power requirements, and size.

The WETStar uses a novel optical flow design that allows for both pump-through and flow-through applications. It is easily mated with CTD packages.

Provides calibrated, high-resolution (60 Hz signal and 1 Hz average) chlorophyll-a measurement of mechanically stimulated bioluminescence to assess water column ecosystem dynamics. The potted optics block results in long term stability of the instrument and the optional anti-biofouling technology delivers truly long term field measurements. more information from Wet Labs

Acronym: WETStar CDOM Fluor

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

Generic Description:

The WETStar CDOM fluorometer measuring fluorescence as a proxy for dissolved matter absorption.
