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.
standardDepths(n = 0)
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.
A vector of depths that are more closely spaced for small values, i.e. a finer grid near the ocean surface.
