   Sampling Methodology
   Sampling Methodology, Optics
 
   PI-Note: To convert Beam C (C(1/m)) to Cp the following
   amount was added to ALL casts:  -0.382
 
   In addition the following casts were adjusted:
 
   98020502        -0.00300
   98021001        -0.01800
 
   AESOPS Investigators, Please note:
   Begin and end parameters for time, latitude and longitude are
   provided in the core CTD and Bottle data.  Investigators
   submitting data related to CTD/Bottle casts are urged to use
   the single lat/lon entry from the Chief Scientist's event log.

Instruments

CTD Sea-Bird 911

Supplied Name: CTD Seabird 911

Supplied Description:

CTD measurements taken, Sea-Bird SBE 9

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.
