Plot Antarctic Circumpolar Current Fronts

by

 

Plot the locations of the major fronts associated with the Antarctic Circumpolar Current.

plot_ACC_fronts.m
% Plot the meridional extent of fronts associated with the Antarctic 
% Circumpolar Current as described by Alex Orsi and others in their 
% landmark work, "On the meridional extent and fronts of the Antarctic 
% Circumpolar Current, Deep-Sea Res. I, 42, 641-673, 1995".  
% 
% This script downloads data from the World Ocean Circulation Experiments 
% Southern Ocean Atlas, which can be found online at 
% http://woceatlas.tamu.edu/Sites/html/atlas/SOA_DATABASE_DOWNLOAD.html.
% 
% Requirements: Matlab, Mapping Toolbox, an internet connection, and the 
% ncpolarm function found here: 
% http://www.mathworks.com/matlabcentral/fileexchange/30414

%% Initialize Antarctica map, argument is northern latitude:
% This step requires the ncpolarm function available on the Mathworks 
% File Exchange website.
