Data Processing Description

Dataset Processing Description

The processed data files submitted to BCO-DMO include 2 plots for each cast: plot 1 contains temperature, oxygen, PAR, and density vs. pressure; plot 2 contains fluorescence, salinity, beam attenuation, and density vs. pressure. Plots have been compiled into a single PDF file: POWOW3 CTD Plots (58.9 MB PDF)

BCO-DMO obtained the processed .cnv files (binned profiles) and replaced values of '-9.990e-29' with 'nd' to indicate 'no data'. Parameter names were modified to conform with BCO-DMO convention. month_utc, day_utc, year, time_start, lat_start, lon_start, and depth_w were taken from the .cnv file headers and the scanned CTD cast logs.

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

Wet Labs ECO-AFL/FL Fluorometer

Supplied Name: ECO AFL/FL

Supplied Description:

Instrument Type

Generic Name: Wet Labs ECO-AFL/FL Fluorometer

Acronym: ECO AFL/FL

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0172/
