sw.depth: Water depth

Description

Compute depth from pressure and latitude.

Usage

d <- sw.depth(p, lat, degrees=TRUE);

Arguments

p

Pressure [dbar].

lat

Latitude in $^\circ$N or radians north of the equator.

degrees

Flag indicating whether degrees are used for latitude; if set to FALSE, radians are used.

Value

• Depth [m].

which is where this R code came from.

Depth in meters from pressure in decibars using Saunders and Fofonoff's method, with the formula refitted for 1980 equation of state

Checkvalue: depth = 9712.653 m for p=10000 decibars, latitude=30 deg above for standard ocean: t=0 deg. celsuis ; s=35 (ipss-78)
