   Sampling Methodology
   DMO note on calculated depth
 
   PI Note:  PROBLEMS WERE ENCOUNTERED WITH THE AMMONIUM ANALYSIS
   AT THE BEGINNING OF THIS CRUISE.  THUS, AMMONIUM DATA
   ARE NOT REPORTED UNTIL STATION 4, CAST 3.
 
   AESOPS Investigators, Please note:
   Begin and end parameters for time, latitude and longitude are
   provided in the core CTD and Bottle data.  Investigators
   submitting data related to CTD/Bottle casts are urged to use
   the single lat/lon entry from the Chief Scientist's event log.

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.
