   EqPac bottle quality review summary from DMO
 
   DMO cautionary note:
   The DMO suspects that event number 03040605 should be changed to
   03040702.  Doing so would correct for bottle number and depth
   misalignments.
   
   Notes:
   Samples preserved with 1% paraformaldehyde, frozen in liquid nitrogen
   and stored at -85 deg C.  Analysis by dual-beam flow cytometry according
   to Monger and Landry, (1993).

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.
