This describes the contents of the bottle directory.

There is one file for each cruise (N1-N9).

The files contain the quality-controlled data derived
from Niskin water bottle samples, merged with the CTD
data at the time of bottle closure.  The files also
contain the references to the analytical methods used
to determine the concentrations of the various parameters.

Surface bucket salinities were taken on cruises N5,N6,N7,
N8, and N9 only. They are assigned a depth of 0m (zero).
