decibar2depth: decibar2depth

In AtlanticR/bio.utilities: Package that interacts with bio providing base-level generic routines to make your life easier.

Description

This function calculates depth in meters from pressure in decibars using Saunders and Fofonoff's method

Usage

decibar2depth(P, lat, Del = 0, method = "default")

Arguments

P	= pressure, in decibars
lat	= degrees latitude
Del	= geopotential anomaly (defaults to 0)
method	= valid values include"default", "seabird", and "unesco", although they all appear to be treated the same

Value

DEPTH = depth in M

Note

/ UNITS: // PRESSURE P DECIBARS // LATITUDE LAT DEGREES // DEPTH DEPTH METERS // DTN. HEIGHT DEL DYN. METERS (geopotenial anomaly in J/kg:: assume 0) // CHECKVALUE: // 1.) DEPTH = 9712.653 M for P=10000 DECIBARS, LAT=30 DEG, DEL=0 // ABOVE FOR STANDARD OCEAN: T=0 DEG CELSIUS; S=35 (PSS-78) // ———————————————————- // Original fortran code is found in: // UNESCO technical papers in marine science 44 (1983) - // 'Algorithms for computation of fundamental properties of seawater'
