 Methodology: see CTD methodology for this cruise
 
 Change history: YYMMDD
    050906: downloaded original data from EDDIES data web site;
            added to OCB database by Cyndy Chandler, OCB DMO
    070302: added depth_n (matlab) and Nis to enable data merge
    070309: OCB DMO corrected bottle numbers (bot, Nis) for cast 1
    070524: units confirmed via email by Larry Anderson (WHOI)
 
 DMO Note: data were recovered from Seabird *.btl bottle files; 
           and only data from the primary sensors were retained; 
           Niskin bottle number is that which was reported by SeaBird, and
           not the N# recorded on the CTD cast log sheets. The Nis 
           Niskin bottle order number should match the number recorded 
           on the CTD cast log sheets.

Instruments

CTD Sea-Bird 911

Supplied Name: SeaBird 911+ CTD

Supplied Description:

SeaBird SBE 911/917 plus CTD

Instrument Type

Generic Name: CTD Sea-Bird 911

Acronym: CTD SBE 911

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0035/

Generic Description:

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.).

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

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.
