 Change history: YYMMDD
    070302: received bottle salinity data files (salt_oc415_4) from L. Anderson;
    070315: added to OCB database by Cyndy Chandler (OCB DMO)
 
 OCB DMO Note: used SID_salts to determine cast, Niskin bottle numbers,
    and depth_n.  event number is from the event log and CTD data were 
    contributed with the calibration data.

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.
