Table XIV C. — Correction to Sound Velocity, Kis.n.p, for Latitude, AK* 



Table XIV D.— Correction to Sound Velocity, K,j „.„, for Temperature, aV, 



Table XIV E. — Correction to Sound Velocity, Kjj.o.p, for Salinity, A^. 



Table XIV F. — Correction to Sound Velocity, ^si,o.p, for Simultaneous Changes in Salinity, Temperature, 



and Pressure, AV.j„

 Example: 



Given, latitude = 30°, depth = 800 meters, temperature = 4.55° C, salinity = 34.40°/oo. 

 From table XIV A, under 800 meters, p = 808 dccibars 



From table XIV B, under 808 decibars, F35.0.P 1, 460. m./sec. 



From table XIV C, under 30°, aV* 0. m./sec. 



From table XIV D, under 4.55° C, aV , 19. 9 m./sec. 



From table XIV E, under 34.40°/oo, AV, -0. 8 m./sec. 



From table XIV F, under 808 db., 4.65° C, and 34.40°/oo, AF..,.„ 0. m./sec. 



Sound velocity, V,.i.p= (sum of above) 1, 479. 1 m./sec.
