Aquatic PAR Biospherical Instruments s/n QSP-200L4 s/n 4550 Calibrated 13 March 2008

Channel 2 is used for most profiles as there were problems with the pump for channel 1
on some stations. Oxygen is taken from channel 1, however there are some bad values
which are not yet flagged.

Data Processing Description

The data have not yet been processed to include hand salinity and oxygen samples.

BCO-DMO Processing Notes
- Awk written to reformat original .avg.btl.csv files contributed by Victoria Coles
- AWK: ANACONDAS_CTDbtl_2_bcodmo.awk
- Header data for bottle data generated from .avg.btl.csv files
- comma delimited reformatted to tab delimited
- I/P header rec with parameter names and units skipped
- BCO-DMO header o/p from routine modeled after original header rec
- First parameter in each original record removed. Artifact of preliminary processing
- Text Date (Jun032010) reformatted to YYYYMMDD
- Time reformatted from HH:MM:SS to HHMMSS
- Decimal places reported for each parameter provided by Victoria Coles

- Two files without Anconda.Num. Replaced with "nd"

19708085.btl.avg.csv

BCO-DMO Processing Notes/17June2011

Data re-submitted after corrections by Victoria Coles, et al
This version of the bottle data corrects an error in a few stations
that resulted in an incorrect average depth for the surface bottles
(e.g. in 09708054.btl.avg.csv) . Other parameters were correctly
averaged. The files are also renamed to include event number, and the
standard deviation columns have been dropped.

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 Description:

WetLabs Model FLNTU s/n FLNTURD-304 Calibrated 10 March 2008

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.

Photosynthetically Available Radiation Sensor

Supplied Description:

Surface PAR Biospherical Instruments QSR-240 s/n 6294 Calibrated 13 March 2008

Aquatic PAR Biospherical Instruments s/n QSP-200L4 s/n 4550 Calibrated 13 March 2008

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

Generic Description:

A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.

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

Supplied Name: Wet Labs CSTAR Transmissometer

Supplied Description:

WetLabs Model CSTar s/n CST - 1117DR Calibrated 30 April 2008

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/

Generic Description:

The C-Star transmissometer has a novel monolithic housing with a highly intgrated opto-electronic design to provide a low cost, compact solution for underwater measurements of beam transmittance. The C-Star is capable of free space measurements or flow-through sampling when used with a pump and optical flow tubes. The sensor can be used in profiling, moored, or underway applications. Available with a 6000 m depth rating.
