all units information taken from bottle .BTL header records

</pre>

10 February 2006: Prepared for OCB data system by and Cyndy Chandler, OCB DMO (WHOI).

Data were processed using the standard set of Seabird utilities,
to generate final 1-decibar pressure sorted downtrace files for all CTD casts.
All final processed *.asc CTD files were downloaded by the OCB DMO
in February 2006 from the SOFeX web site at MBARI: 
http://www.mbari.org/SOFeX/Melville_Data/CTD/Melville_CTD.htm

The date, time, latitude
and longitude position information were taken from the CTD header records in the *.BTL files,
and therefore disagree slightly with the entires for those CTD cast events in the
cruise event <a href="http://ocb.whoi.edu/jg/serv/OCB/SOFeX/Melville/log.html0">Activity Log</a>

Final CTD cast header record from a .BTL file: 
<a href="http://ocb.whoi.edu/SOFeX/PI-NOTES/SIO_MV_002.BTL">SIO-CTD cast 2
</a>

Note: Temp is T90 (ITS-90 scale confirmed from .BTL file headers) 
only data from the primary temperature and conductivity sensors was kept for the final CTD data

Final CTD cast configuration (con report) files were not provided with .ASC files.

Instruments

CTD Sea-Bird 911

Supplied Name: CTD Seabird 911

Supplied Description:

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.). More information from Sea-Bird Electronics.
