Southern Ocean Frontal Distributions (Orsi)

A data set package with the "Orsi" and "Park/Durand" fronts as 'SpatialLinesDataFrame' objects. The Orsi et al. (1995) fronts are published at the Southern Ocean Atlas Database Page, and the Park et al. (2019) fronts are published at the 'SEANOE' Altimetry-derived Antarctic Circumpolar Current fronts page, please see package CITATION for details.

Orsi and Park/Durand fronts in Spatial form

The “Orsi fronts” are a commonly used climatological map of Southern Ocean frontal distributions, published on the Southern Ocean Atlas Database Page after Orsi et al (1995).

(This page once was at an old link now listed in this package CITATION file as a note).

The “Park/Durand” fronts are a recent update on the locations of the fronts from altimetry data, at the SEANOE Altimetry-derived Antarctic Circumpolar Current fronts page.

See the package vignette/s for more details, and use citation("orsifronts") for information on the sources.
