Data Processing Description

 Change history: YYMMDD
    070402: downloaded original data from SOFeX project data web site;
            added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
            event date, time, lon and lat are from Melville event log; 
            event_SFX is from the multi-ship event log

02 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.

Contact: Craig Hunter

Metadata were taken from the Melville cruise event log when the original data were added to the OCB database.

all event, time, lon and lat data for events are from Melville cruise event log
event_SFX (the SOFeX multi-ship event number), patch day data (pDay_N and pDay_S) are from the multi-ship event log contributed by Michael Hiscock

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.

Trace Metal Bottle

Supplied Description:

Instrument Type

Generic Name: Trace Metal Bottle

Acronym: TM Bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

Trace metal (TM) clean rosette bottle used for collecting trace metal clean seawater samples.
