name of equation of state to be used, either <code>"unesco"</code> or
      <code>"gsw"</code>.

Compute $\sigma_t$, a rough estimate of
  potential density of seawater, minus 1000 kg/m$^3$.

misc

Supports the analysis of Oceanographic data, including ADCP
 measurements, CTD measurements, sectional data, sea-level time series,
 coastline files, etc.  Handles dozens of specialized functions for calculating
 seawater properties such as potential temperature and density, as well as
 derived properties such as buoyancy frequency and dynamic height. Map projections
 are calculated using PROJ.4 functions included within the oce.
