   PI:              Robert Olson and Heidi Sosik
   of:              Woods Hole Oceanographic Institution
   dataset:         Picophytoplankton abundance and biomass
   dates:           January 13, 1997 to February 08, 1997

   Method Note: 5-ml preserved samples were analyzed using a modified version of
   the flow cytometer in which each optical signal was split and
   measured by two photomultipliers at different gain settings, which
   increased the dynamic range of the measurements (allowing cells
   ranging in size from 1 to 40 micrometers to be analyzed
   simultaneously).
 
   DMO note regarding parameter names:
   In the parameter names listed below, lt40 indicates
   cells ranging in size from 1 to 40 microns.

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.

Trace Metal Bottle

Supplied Description:

Trace metal (TM) clean rosette bottles were used to collect water samples.

Instrument Type

Generic Name: Trace Metal Bottle

Acronym: TM Bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

Trace metal (TM) clean rosette bottle used for collecting trace metal clean seawater samples.
