Dataset acquisition description

   PI:             Brent Lewis and George Luther
   of:             University of Delaware
   dataset:        Dissolved manganese concentrations from CTD casts
   dates:          March 15, 1995 to April 08, 1995
   location:       N: 22.4858  S: 9.9993  W: 58.0005  E: 68.7302
   project/cruise: Arabian Sea/TTN-045, Process cruise #2 (Spring Intermonsoon)
   ship:           R/V Thomas Thompson
 
   Lewis Note regarding 9/98 re-submission of data:
   Data for dissolved and total dissolvable Mn have been corrected to
   account for a prior error in calibration.  Current values have been
   verified by comparison to the NASS-4 SRM and by DDDC/APDC extraction
   with GFAAS analysis.

Brent Lewis notes and methods for manganese concentrations

Notes:

    1. Dissolved manganese (Mn) concentrations are in nmoles/liter.

    2. Filtered (Mn_filt) samples were passed through a 0.45 micron
    membrane filter.

    3. Samples were acidified with Q-HCl to pH

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

CTD/Niskin Rosette bottles.

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.
