This week at DaSH we will have Jo Whittaker from IMAS telling us all about how to produce publication-ready maps and figures using the package GMT (http://gmt.soest.hawaii.edu/). GMT is an open source collection of command-line tools for manipulating geographic and Cartesian data sets and producing PostScript illustrations ranging from simple x–y plots via contour maps to artificially illuminated surfaces and 3D perspective views. Jo is pretty keen on GMT, and from what she has shown me so far I may soon be keen on it too. So if you think your usual analysis software is a bit limited and clunky when it comes to figures for publication then GMT may be just what you are looking for.
Coming up in the next week or so we will be holding a session with some experienced operators showing you how to best plot those common figures that we all need from time to time. Examples that I can think of include; maximal or minimal sea ice extent; location of the fronts of the Antarctic Circumpolar Current, bathymetry for somewhere (or everywhere) or climatological sea surface temperature or ocean colour. Where do those data sets come from, and how best to plot them in various packages?
