Data Processing Description

SOFeX 2002 Multi-ship POM data

01 April 2007: Prepared for OCB data system by Cyndy Chandler, OCB DMO (WHOI).

OCB DMO Processing Notes:

The Particulate Organic Matter (POM) data were contributed as a collection of tables in an Excel spreadsheet file.
No documentation was contributed with the data. View or download original POM data file as an:
Excel file or converted to PDF file.

Mark Altabet and David Timothy also contributed a Microsoft Word document with two figures of POM data showing
concentrations of POC and PON for selected stations at different locations with respect to the South patch.
View the POM figures (converted from MS Word to PDF format; dates were not corrected - see OCB DMO note below).

Some metadata were altered when the original data set was added to the OCB database.

date was changed to January 29 (from February 29) for Melville station 4 CTD011 S_in
original dates for Melville CTD034, CTD058 and CTD068 events all disagreed with data in cruise event log and multi-ship
event log, so dates in this POM data set were changed to match the event logs
all event, time, lon and lat data for events from both cruises are from individual cruise event logs
event_SFX (the SOFeX multi-ship event number) is from the multi-ship event log contributed by Michael Hiscock

A comment in the original Excel data file notes that depth reported for
Revelle station 28 (type SIO4 and patch_loc S_in) is approximate due to a hydrocast failure during that sampling event.

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.

Parameters
