calc_fixed_depth_var_bt: Estimate value of a profile variable at a fixed depth

In afsc-gap-products/gapctd: Process CTD data from bottom trawl surveys

Estimate value of a profile variable at a fixed depth

Description

Algorithm used since 2013 to estimate temperature at 1-m (RACE_DATA.TEMPERATURE_METHOD.TEMPERATURE_METHOD_ID = 14) from temperature-depth recorders deployed on RACE bottom trawl surveys. Returns the variable value corresponding with the first depth value at or shallower than the reference depth. If no depth values are equal to the reference depth, the variable value is estimated by interpolating from the variable values above and below the reference depth.

Usage

calc_fixed_depth_var_bt(depth, var, ref_depth)

Arguments

depth	Numeric vector of depth values
var	vector of variables
ref_depth	Reference depth for estimating 1L numeric vector
