VARIOUS PROPERTIES OF SEA WATER ARE CALCULATED FROM THE SETS up READ- 

 INGS OF PRESSURE (OR DEPTH), TEMPERATURE AND SALINITY TAKEN AT A STA- 

 TION. SOME RESULTS ARE GIVEN AT OBSERVED, AND SOME AT STANDARD, PRES- 

 SURES. THERE ARE SEVERAL VERSIONS OF THIS PROGRAM DEPENDING UN WHETH- 

 ER PRESSURE OR DEPTH IS INPUT. AUTHOR — JAMES CREASE. REF. N.I.O.

INTERPOLATION OF SPECIFIC VOLUME ANOMALY LANGUAGE - FORTRAN 



COMPUTER - IBM 7074 

 (COPY ON FILE AT NODC) 



COMPUTES SPECIFIC VOLUME ANOMALIES AND DYNAMIC DEPTH ANOMALIES AT OB- 

 SERVED LEVELS. FIELDS OCCUPY THE SAME POSITIONS AS ON THE NODC FORMAT 

 STANDARD CARD AND REPLACE SOME CHEMISTRY FIELDS. AT STANDARD DEPTHS 

 SPECIFIC VOLUME ANOMALIES ARE INTERPOLATED FROM THE OBSERVED LEVELS 

 RATHER THAN COMPUTED FROM INTERPOLATED TEMPERATURE AND SALINITY AS HAS 

 BEEN DONE PREVIOUSLY. DYNAMIC DEPTH ANOMALIES AT THESE STANDARD 

 DEPTHS ARE THEN COMPUTED FROM THESE INTERPOLATED SPECIFIC VOLUME ANOM- 

 ALIES. AN OUTPUT LISTING MAY BE MADE WHICH COMPARES THE TWO FIELDS AT 

 STANDARD DEPTHS WITH THE SAME TWO FIELDS APPEARING ON THE INPUT DATA 

 TO SHOW THE RESULTANT DIFFERENCES. OS NO. 52232. AUTHOR — ROBERT VAN

INTERPOLATION FOR OCEANOGRAPHIC DATA LANGUAGE - FORTRAN 



COMPUTER - CDC 3200 AND

INTERPOLATES THE VALUES OF DEPTH, TEMPERATURE, AND SALINITY AT ISEN- 

 TROPIC LEVELS (CONSTANT VALUES OF THE DENSITY FUNCTIONS). USES A FOUR- 

 POINT LAGRAN6IAN POLYNOMIAL, EXCEPT MODIFICATIONS ARE MADE WHERE COM- 

 MON OCEANOGRAPHIC CONDITIONS DISTORT THE POLYNOMIAL. A DETAILED TECH-

AN OCEANOGRAPHIC DATA PROCESSING SYSTEM DESIGNED TO ACCEPT THE DATA 

 FROM THE ORIGINAL LOG SHEETS. COMPUTES OBSERVED TEMPERATURES AND 

 PRESSURES FROM THERMOMETER READINGS, SALINITIES FROM THE CONDUCTIVITY 

 RATIO READINGS, THE DISSOLVED OXYGEN FROM THE TITRES AND THE REACTIVE 

 SILICA CONCENTRATIONS FROM THE OPTICAL DENSITIES. THE DATA INPUT MAY 

 BE PUNCHED PAPER TAPE FROM THE PDP-8 SYSTEM (B.I. COMPUTER NOTE 68-5- 

 C) OR PUNCHED CARDS. THE FINAL PROGRAM IN THE SYSTEM COMPUTES DEPTH,
