SPVOL, DSPVOL LANGUAGE - FORTRAN IV-H 



COMPUTER - SDS SIGMA 7 



SUBROUTINE COMPUTES THE SPECIFIC VOLUME OF SEAWATER AT A GIVEN TEMPER- 

 ATURE, PRESSURE, SIGMA-0 AND SIGMA-T, USING THE FORMULA BY V.W. EKMAN, 

 REWRITTEN BY FQFONOFF AND TABALA (P.O.G. MANUSCRIPT SERIES NO. 25). 

 DSPVOL IS A FORM OF SPVOL USING DOUBLE-PRECISION VARIABLES. 'ALPHA', 

 THE OUTPUT FROM THE SUBROUTINE, IS THE SPECIFIC VOLUME IN MILLIlITRES 

 PER GRAM. THE USE OF SUBROUTINE SI6MAT WOULD BE REQUIRED BEFORE CALL- 

 ING SPVOL, AND DSIGMT WOULD BE REQUIRED BEFORE CALLING DSPVOL. STOR- 

 AGE REQUIREMENTS — 239(10) LOCATIONS FOR SPVOL, 204(10) LOCATIONS FOR 

 DSPVOL. WRITTEN IN FORTRAN II FOR THE GE 225 BY J. WEBSTER, CONVERTED 

 TO FORTRAN IV-H BY M. HUNT (APRIL 1968).

PRESS LANGUAGE - FORTRAN IV-H 



COMPUTER - SDS SIGMA 7 



SUBROUTINE COMPUTES A SERIES OF PRESSURES FROM A GIVEN SERIES OF 

 DEPTHS, TEMPERATURES, SALINITIES, AND THEIR LATITUDE. THE EQUATION 

 FOR PRESSURE IS INTEGRATED BY SUCCESSIVE APPROXIMATIONS.
