oce (version 0.5-1)

Analysis of Oceanographic data

Description

Supports the analysis of Oceanographic data, including ADP measurements, CTD measurements, sectional data, sea-level time series, coastline files, etc. Provides functions for calculating seawater properties such as potential temperature and density, as well as derived properties such as buoyancy frequency and dynamic height.
