   PI note:  Biomass is calculated using a constant carbon density factor of 220
   femtograms C per um^3 of biovolume, and is expressed in units of
   micrograms of carbon per liter.
   Biovolume is defined as average cell size.

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.
