 OCEANOGRAPHIC DATA 



Cruises Listed 



Table I — University of Washington, May 1969 



Table II— USCGC SOUTHWIND, August 1969 



Table III— USCGC WESTWIND, September-October 1969 



Codes Utilized 



A complete description of the codes utilized in the tabulation of oceanographic station data can be 

 found in National Oceanographic Data Center publication M-2, Processing Physical and Chemical Data 

 from Oceanographic Stations. (Rev. August 1964, supplement issued May 1966.) 



To facilitate use of the oceanographic station data listing, entry headings which are not self-explan- 

 atory are described below. 



Depth to bottom Corrected or uncorrected sounding in meters. 



Max. depth of samples Depth of deepest sample to nearest multiple of one hundred meters. 



Wave observations: 



DIR Rounded to nearest multiple of ten degrees. 



HGT In increments of }4 m. Sum of 5 meters plus increments of }^m if 50 is added to direction. 



PER If numerals 2 through 9 are entered, period in seconds is twice the numeric entry or 2X 



(numeric entry) + 1. For other entries see WMO Code 3155. 



SEA Sea state according to WMO Code 3700. 



Weather code If preceded by X, weather according to WMO Code 4501. If a two-digit entrj', weather 



according to WMO Code 4677. 

 Cloud code: 



Type Cloud type according to WMO Code 0500. 



Amount Cloud amount in eights. Entry of the numeral 9 indicates cloud amount could not be 



estimated. 

 Water: 



Color code Color according to Forel-Ule scale. 



Trans Transparency in whole meters as determined by Secchi disc. 



Wind: 



Dir Rounded to nearest multiple of ten degrees. 



Speed or force If preceded by letter S, wind speed in knots ; if preceded by letter F, wind force according 



to Beaufort scale. 



Barometer Barometric pressure given in tens, units and tenths of millibars. 



Air temp., °C Air temperature to tenths of a degree centigrade. 



Vis. code Visibihty according to WMO Code 4300. 



No. obs, depths Number of observed levels associated with the station. 



Messenger time Entered in hours and tenths of an hour GMT. For Nansen casts, indicates time of release 



of messenger applicable to the observational level. For STD casts, incicates the starting 

 time of lowering the sensor. 

 Card type OBS designates observed levels. STD indicates the values at this standard level were in- 

 terpolated by a modified 3-point LaGrange formula. 



Depth (m) Depth to nearest meter. A postscript T indicates depth was obtained thermometrically; 



Z indicates uncorrected "wire out" depth. Postscript Q indicates value was marked 

 doubtful by originator; P indicates value was considered doubtful by NODC. Post- 

 scripts P and Q retain this meaning throughout the following entries. 



T°C Temperature to hundredths of a degree Centigrade. 



S °/oo Salinity in parts-per-thou.sand. 



SIGMA-T Entered to hundredths. 



Specific-volume Multiply entry by 10^' to obtain specific-volimie anomly in cubic centimers per gram.
