Methods & Sampling

 dates:           21 January 2002 to 21 February 2002  (20020121-20020221) 
 location:        N: -52.3853  S: -66.6115  W: -175.2212  E: -166.9392 
 project/cruise:  SOFeX/MV

PI note: All of these samples were run at sea and data are considered preliminary.

Data Processing Description

Change history:
    070501: downloaded original data (MelvilleStationDataNuts.xls) from SOFeX project data web site.
            data prepared by Dave DuBois (OCB DMO, WHOI)
    080814: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
  
 PI note: All of these samples were run at sea and data are considered preliminary.
 
 OCB DMO Note: 'CRM' and 'TM' type casts were reported in one worksheet called 'Total'. Data are
            presented as sorted in the contributed Excel file, with records sorted first by
            cast type (CRM or TM) and then by time. Date, time and position are from the
            original data file and not the cruise event log. The 'bot' parameter (bottle number)
            could be used as a proxy for depth, or used to retrieve depth data from the SIO_bottle 
            data object.
            
            The latitude in the original Excel file for station 7 CTD cast 19 was reported as
            a different value for each bottle sample.  Those values ranged from -0.0470 to 0.4720.
            The DMO replaced those values with a single latitude from the cruise event log.

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.

Parameters
