Data Processing Description

Dataset Processing Description

Refer to individual platform deployments for details on CTD data processing.

Deployment-specific processing description

The data were processed using SeaBird Electronics' processing with their standard, 
recommended parameters. The procedure used for quality control and calibration post 
processing follows that developed at NOAA's Pacific Marine Environmental Laboratory 
in the Eco-FOCI (Fisheries and Oceanography coordinated Investigations). Each cast 
was then inspected for reasonableness and for spikes using the criterion that for 1-m 
bin data, sigma-t inversions > 0.02 were unacceptable. Temperature or conductivity 
values causing such inversions were removed and the result data gaps were linearly 
interpolated. 
 
Water samples, taken approximately every third station, were analyzed for salinity using an autosal 
aboard the vessel. The results were compared to data measured by the CTD sensor to determine the 
calibration correction for the salinitiy values. The resulting corrections were applied to all the 
profile data.

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.).
