Methodology 
 
 Change history:  YYMMDD
    060123:  Added by Cyndy Chandler (cchandler@whoi.edu), OCB CDMO
    060905:  remove O2, T, C and derived params from station 20 per Chief Scientist request; 
             sensor caps left on during deployment
          
 DMO note: event, date, time, latitude and longitude are from the CTD cast 
           NMEA header lines; T_local (local time at study area) was computed 
           by adjusting GMT time by +11
           
           As of January 2006, oxygen, fluorescence, turbidity, transmissivity
           and PAR had not yet been compared with in-situ data and should
           be used by others with caution until finalized.

           PIC sensor: voltage 0 - 5: WET Labs PIC 001 (4th build)
           POC sensor: voltage 0 - 5: WET Labs CST-DR 391 - tranmsissometer
           scattering sensor: voltage 0 - 5: Seapoint scattering sensor

Instruments

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.
