Description

This dataset includes temperature, salinity, pressure, depth, sigma-theta density, PAR, fluorescence, and dissolved oxygen associated with CTD bottle samples collected during the R/V Point Sur cruise PS13-12 between 2013-06-27 2013-07-05.

The data are available by clicking the "Get Data" button on this page.

Original .btl files submitted to BCO-DMO are available for download as a zip file:
Sea-Bird .btl files (186 KB ZIP, 648 KB uncompressed)
* The "BCO-DMO Data Manager Processing Notes" do not apply to these .btl files.
* The .btl files contain sensor calibration information for each cast.

Methods & Sampling

Dataset acquisition description

Bottle samples were collected during hydrocasts conducted at stations using a SeaBird CTD with redundant sensors for temperature and conductivity; the instrument package was owned and operated by the R/V Point Sur (Moss Landing Marine Laboratories, Moss Landing, California). Prior to the cruise, the transmissometer was not calibrated and many data anomalies were observed; therefore, these data are suspect and not reported with this dataset.

Data Processing Description

Dataset Processing Description

All hydrocast data was processed to1-m bins.

Originally submitted .btl files generated by Sea-Bird Seasave V 7.22.

BCO-DMO Data Manager Processing Notes (what was done to the original .btl files):
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values replaced with no data value 'nd'
* processed using scripts to convert .btl to .csv to import into BCO-DMO system (originals available as .zip download)
* original files included two parameters names concatenated together so these were split 'CStarAt0Sbeox0Mm/Kg' to CStarAt0 and Sbeox0Mm/Kg
* special characters in data parameter names replaced
* precision %.3 except Spar %.2f lat lon %.5f
* added ISO DateTime UTC which was generated from Date and Time values
* 0 prepended to single digit cast numbers for consistency with other datasets in project

Instruments

CTD Sea-Bird 9

Supplied Name:

Supplied Description:

Sensor and calibration information for all casts can be found in the original .btl file zip file available on the dataset landing page: https://www.bco-dmo.org/dataset/701430

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

Fluorometer

Supplied Name: Fluorometer, 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.

LI-COR Biospherical PAR Sensor

Supplied Name: PAR/Irradiance, Biospherical/Licor

Supplied Description:

Instrument Type

Generic Name: LI-COR Biospherical PAR Sensor

Acronym: LI-COR Biospherical PAR

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0074/

Generic Description:

The LI-COR Biospherical PAR Sensor is used to measure Photosynthetically Available Radiation (PAR) in the water column. This instrument designation is used when specific make and model are not known.

Sea-Bird SBE 43 Dissolved Oxygen Sensor

Supplied Name: Oxygen, SBE 43

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE 43 Dissolved Oxygen Sensor

Acronym: SBE-43 DO

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0036/

Generic Description:

The Sea-Bird SBE 43 dissolved oxygen sensor is a redesign of the Clark polarographic membrane type of dissolved oxygen sensors. more information from Sea-Bird Electronics
