   EqPac bottle quality review summary from DMO
 
   DMO cautionary note:
   The DMO suspects a misalignment of bottle numbers with corresponding
   depths/pressures for event number 02041830.  In question are the values
   reported for bottles 17 and 14 at nominal depths of 60 and 90 meters.
   These depths align correctly with bottles 18 and 15.  Bottles 17 and 14
   should have depths of 70 and 100 meters.
 
   These correlations are based on the event/bottle number/depths reported
   by Murray in his final bottle cast file.

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.
