   PI:              Dennis Hansell and Craig Carlson
   of:              Bermuda Biological Station for Research
   dataset:         Total organic carbon (TOC) from CTD casts
   dates:           December 04, 1997 to December 26, 1997
   location:        N: -53.0292  S: -64.7418  W: -174.7295  E: -168.8325

   Methodology
 
   PI Note: Polar Front samples were not filtered, therefore these analyses
   are of total organic carbon and not dissolved organic carbon.

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

CTD clean rosette (Niskin) bottles were used to collect water samples.

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.
