 Change history: YYMMDD
    070308: downloaded original data from EDDIES data Web site 
            (200609 DM FINAL_corrected.xls);
            prepared for OCB database by Nancy Copley, OCB DMO
    070313: added to OCB database by Cyndy Chandler, OCB DMO
            event number is from cruise event log
    070405: per Jason Perl, units for all pigment concentrations  
            changed from microgram/kilogram to microgram/liter 
 
 PI note: 080317: Recalibrated data are expected from NASA during the second half of 2008.

Technician notes:
note 1: Did not have a signal for Chl_a @ 450nm (sample too dilute to get a chromatogram peak)
note 2: Did not have a signal for Chl_a @ 450nm or 436nm (sample too dilute to get a chromatogram peak)
note 3: no ancillary data; default volume filter set to 4000mL

chl_a_fluor and pheo_fluor are values from a Turner Fluorometer. Each HPLC extract is run on the Fluorometer as a second measure of Chla. Chla, MVa, DVa using the C18 HPLC method, yield a single peak for Chla, measured at 436nm and 450nm. A regression equation, between the 2 wavelengths (based on calibration curves of 100% MVa and 100% DVa), is used to give values for each pigment within a single peak. Chla @436nm is reported for comparison with legacy data (that are often only listed simply Chla).

Original Excel file downloaded from EDDIES Web site: copy of original Excel file

The comments in the data object were taken from the 061127 version of file readme_jason_notes.txt.
SID_Filter and SID_PI were identical but some samples were also included another sample designation that was a consecutive SID_PI. In these cases, the consecutive SID replaced the SID_PI.

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
