Data 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: POWOW2 CTD Plots (44.3 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 file named "POWOW2-ctdfilelist.txt" included in the original data submission.

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

Supplied Name: LI-COR Biospherical PAR

Supplied Description:

Instrument Type

Generic Name: LI-COR Biospherical PAR Sensor

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/

Generic Description:

The Environmental Characterization Optics (ECO) series of single channel fluorometers delivers both high resolution and wide ranges across the entire line of parameters using 14 bit digital processing. The ECO series excels in biological monitoring and dye trace studies. The potted optics block results in long term stability of the instrument and the optional anti-biofouling technology delivers truly long term field measurements.

WET Labs {Sea-Bird WETLabs} C-Star transmissometer

Supplied Name: WL CSTAR Trans

Supplied Description:

Instrument Type

Generic Name: WET Labs {Sea-Bird WETLabs} C-Star transmissometer

Acronym: WL CSTAR Trans

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0160/
