R: Standard Oceanographic Depths

standardDepths {oce} | R Documentation

## Standard Oceanographic Depths

### Description

This returns a vector of numbers that build upon the shorter lists provided in Chapter 10 of reference 1 and the more modern World Ocean Atlases (e.g. reference 2). With the default call, i.e. with `n=0`, the result is `c(0, 10, 20, 30, 40, 50, 75, 100, 125, 150, 200, 250, seq(300, 1500, by=100), 1750, seq(2000, 10000, by=500))`. For higher values of `n`, progressively more and more values are added between each pair in this sequence. See the documentation for `sectionGrid()` for how `standardDepths` can be used in gridding data for section plots.

### Usage

    standardDepths(n = 0)

### Arguments

`n` | Integer specifying the number of subdivisions to insert between each of the stated levels. For exmple, setting `n=1` puts a 5m level between the 0 and 10m levels, and `n=2` puts 3.33 and 6.66 between 0 and 10m.

### Value

A vector of depths that are more closely spaced for small values, i.e. a finer grid near the ocean surface.
