ABOUT CROSSOVER_TOOLBOX:

This set of m-files was created and developed during the secondary 
quality control of the CARINA data set.

This package allows users to perform consistency control (or secondary 
quality control) of hydrographic data using crossover analysis. The 
package also includes MATLAB routines to read the merged CARINA data files.
Crossover location refers to cruise tracks that crosses each other, or at 
least comes close to each other. For each crossover, comparisons of 
the parameter concentrations were made in the deep part of the water 
column, normally > 1500 meters depth. The result of each cross over 
is an offset and a standard deviation of the offset. These offsets 
(and their uncertainty) were used to generate a set of corrections for 
each cruise with a set of least square models (inversions). Using the 
results from the inversion, the analyst can come up with a set of 
adjustments that should (could) be applied to the data in order to 
make the dataset internally consistent. For more information, see 
Tanhua et al. (and references therein) in the CARINA special issue in 
Earth Systems Science Data, 2009 (in preparation).

For more information, please refer to the PDF file included in this package.



INSTALLING:

Download the zip directory and place the file(s) in a location that 
Matlab can see (or add the location of the file(s) to Matlab's search 
path). You will also need to have m-map installed on your system 
(available at http://www.eos.ubc.ca/~rich/map.html
.
See the attached pdf to get started.
