   Methodology:
   Peltzer, Edward T. (1993).  Shipboard determination of total
   organic carbon by a high temperature combustion/direct
   injection technique.  U.S. Joint Global Ocean Flux Study -
   Equatorial Pacific Protocols, 1993, section 21A.
 
   DMO cautionary note:
   Dr. Peltzer has corrected his data to reflect the bottle cast
   tripping problems reported by Dr. Murray.  Events 02180600 and 02261720
   report bottles 24 and 1 tripped at the same depth.

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.
