Note: These files were originally part of the oceanography toolbox compiled by R. A sonar signal is sent from a ship at a point just below the water surface and 18s later the reflected signal is detected. Sndspd – Computes the speed of sound in seawater using any one of 5 (user selectable) formulations.Pressure – Computes pressure given the depth at some latitude.93, 255275 (1993) J Acoust Soc Am (May 1994) Further evidence that the sound-speed algorithm of Del Grosso is more accurate than that of Chen and Millero. Potentmp – Computes potential temperature from in-situ measurements. Comments on ‘‘On equations for the speed of sound in seawater’’ J.Depth – Computes depth given the pressure at some latitude.Adiabat – Computes the adiabatic temperature gradient.Shell-scripts that I have collected and modified/optimized for use on a PC (see note below): Vsnd_un95 – Calculate the speed of sound in seawater using the UNESCO 1995 sound speed equation for seawater as determined by Wong and Zhu (1995).Vsnd_stp2 – Calculate the speed of sound in seawater using the van ‘t Hoff equation with coefficients fitted to a data matrix calculated using the TEOS-10 complete EoS for seawater.Vsnd_stp1 – Calculate the speed of sound in seawater using the van ‘t Hoff equation with coefficients fitted to a data matrix calculated using the UNESCO 1995 speed of sound equation for seawater as determined by Wong and Zhu (1995).vapprs – Calculate the vapor pressure of water as a function of (S,T,P) according to Weiss and Price (1980).sbec2sal – Calculate the salinity (pss) of seawater from conductivity (mS/cm), T and P. salinity – Calculate the salinity (pss) of seawater from conductivity (S/m), T and P.pH_total – Calculate pH of the total scale, plus all of the CO 2 system parameters from S, T, P, phosphate, silicate, alkalinity, and total CO 2.o2satv2b – Calculate oxygen saturation (umol O2/kg) as a function of S and T according to Garcia & Gordon (1992).My teacher gave us the speed in water at 20C which 1482m/s. What is the wavelength of such a wave in seawater at 25C i know how to solve this one, all i need is the speed of sound waves in seawater at 25 degrees Celsius. o2satv2a – Calculate oxygen saturation (ml O2/L) as a function of T and S according to Garcia & Gordon (1992). Dolphins emit ultrasonic waves with a frequency as high as 5.5 x 105Hz.o2sat – Calculate oxygen saturation as a function of S and T.n2satv2 – Calculate nitrogen saturation as a function of T and S according to Hamme & Emerson (2004).
