  Sampling Methodology

  DMO note on calculated depth

  AESOPS Investigators, Please note:
  Begin and end parameters for time, latitude and longitude are
  used in the core CTD, Bottle and TM bottle data.  Investigators
  submitting data related to CTD/Bottle/TM casts are urged to use
  the single lat/lon entry from the Chief Scientist's event log.

  DMO note (020409): add several events to facilitate bottleTM merge:
      added events: 04121818, 04141658 and 04201924
      For these events ONLY, depth is nominal depth (depth_n) and pressure
      was calculated from depth_n
 
  DMO note (020513): add depth calculated from pressure

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.
