Read a World Ocean Atlas NetCDF File

Supports the analysis of Oceanographic data, including 'ADCP'
measurements, measurements made with 'argo' floats, 'CTD' measurements,
sectional data, sea-level time series, coastline and topographic data, etc.
Provides specialized functions for calculating seawater properties such as
potential temperature in either the 'UNESCO' or 'TEOS-10' equation of state.
Produces graphical displays that conform to the conventions of the
Oceanographic literature. This package is discussed extensively by
Kelley (2018) "Oceanographic Analysis with R" <doi:10.1007/978-1-4939-8844-0>.

<dt>name</dt>
<dd>of variable to extract. If not provided, an
error message is issued that lists the names of data in the file.</dd>
<dt>positive</dt>
<dd>logical value indicating whether <code>longitude</code> should
be converted to be in the range from 0 to 360, with <code>name</code>
being shuffled accordingly. This is set to <code>FALSE</code> by default,
because the usual oce convention is for longitude to range between -180
to +180.</dd>

Arguments

<pre><code>
# Mean SST at 5-degree spatial resolution
tmn &lt;- read.woa("~/data/woa13/woa13_decav_t00_5dv2.nc", "t_mn")
imagep(tmn$longitude, tmn$latitude, tmn$t_mn[, , 1], zlab="SST")
