   PI:              Diane Stoecker
   of:              Univ. of Maryland, Horn Point Lab.
   dataset:         Microplankton counts and carbon biomass, one liter samples
   dates:           October 02, 1992 to October 20, 1992
   location:        N: 0.013  S: -0.007  W: -140.1523  E: -139.9753
   project/cruise:  EqPac/TT012 - Fall Time Series
   ship:            R/V Thomas Thompson
 
   PI-Notes:
   Samples obtained by drawing a one liter sample of water from Niskin bottles.
   Samples preserved with 20% buffered formalin.  Samples concentrated by
   sedimentation prior to microscopy.  Ciliate counts and carbon
   biomass corrected for cell loss during fixation.
 
   All organism counts are for size class greater than 20 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.
