CTD Data for SOIREE Cruise in Matlab Format

There is one Matlab binary .mat file for each down cast and one
for each up cast. File names are of the form t1101_1.mat for the
down cast and t1101_1u.mat for the up cast; where t is the station
register; 1101, the station number; and 1, the cast number.

Each file contains the following Matlab variables:

	Circumstances
ca         1x1  double array  Cast Number
cr         1x4  char array    Cruise Number - always 3052
end_time   1x20 char array    End Time [UTC]
lat        1x1  double array  Start Latitude []
lon        1x1  double array  Start Logitude []
reg        1x1  char array    Station Register - always T
st         1x1  double array  Station Number
start_time 1x20 char array    Start Time [UTC]
up         1x1  double array  1 for up cast, 0 for down cast

	2-decibar bin-averaged data
f          nx1  double array  Fluorescence [Volts] (*)
p          nx1  double array  Pressure [decibars] (*u)
par        nx1  double array  PAR [Volts] (*)
s          nx1  double array  Salinity [PSS-78] (*u)
t          nx1  double array  Temperature [C, ITS-90] (*u)
tr         nx1  double array  Transmission [%] (*)

All circumstances or metadata have been quality controlled.

All 2-decibar bin-averaged data have been calibrated and quality
controlled, with the exception of:

*	Fluorescence, Transmission and PAR for both down and up
	casts.

*u	Pressure, Temperature and Salinity for up casts.

The up cast data are included for completeness and are inherently
limited as a source of high-accuracy hydrographic data because
of the location of the temperature and conductivity sensors in
the wake of the underwater package.

NaNs in the 2-decibar bin-averaged data indicate data that are
missing or flagged as bad.
