Data Processing Description

 
 Change history: YYMMDD
   061215: original data received from Susan Brown (UH Manoa);
   070129: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
   070328: update metadata from new version of cruise event log
   070503: data is now considered final following PI review
 
 OCB DMO Note: event, date, time, lon, lat and ev_type taken from event logs
 
 PI note:

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.
