This contains information about the underway CTD data collected on monthly
cruises from the Southern California Marine Institute (SCMI) to the Wrigley Institute (WI)

For more information, see: http://www.icess.ucsb.edu/iog/uCTD/

(This data represents the downcasts averaged into 1db bins)

These *.csv (comma separated value) files should be easily opened in any
spreadsheet program.

--------------------

The filename is in the following format:

uctdyyyymmdd.csv

Where;

'uctd' designates this as 'underway CTD' data
'yyyy' is four digit year
'mm' is two digit month
'dd' is two digit day of month

--------------------

There are sixteen columns of data:

1)  Matlab serialtime  (see: http://www.mathworks.com/access/helpdesk/help/techdoc/ref/datenum.html )
2)  year
3)  month
4)  day
5)  hour
6)  minute
7)  second
8)  'leg', where 1 = SCMI->WI and 2 = WI->SCMI
9)  distance from WI (km)
10) latitude of cast (N)
11) longitude of cast (W)
12) pressure (db)
13) conductivity (Siemens m^-1)
14) temperature (deg C)
15) salinity
16) density (kg/m^3)
17) Brunt-Vaisala (or buoyancy) frequency (cycles per hour)
18) potential temperature
19) potential density anomaly
