public OceanModel()

Method Details

pressure

public static Real pressure(Real depth)

Hydrostatic pressure at depth. P = P_atm + rho * g * h

Parameters:

depth - depth meters (positive downwards)

Returns:

Pressure (Pa)

speedOfSound

public static Real speedOfSound(Real tempCelsius,
 Real salinityPPT,
 Real depthMeters)

Speed of sound in seawater (Chen-Millero-Li approximation, simplified). C ~ 1449.2 + 4.6T - 0.055T^2 + ... + 1.39(S - 35) + 0.016z

Parameters:

tempCelsius - Temperature in Celsius

salinityPPT - Salinity in parts per thousand (e.g. 35)

depthMeters - Depth in meters

Returns:

Speed of sound (m/s)
