Preliminary visualisations of the Global Ocean as a volume. Derived from the CARS 2009 data (Jeff Dunn, CSIRO), massaged by Paul Bourke (WASP), for a current project I am working on to visualise the world's oceans using a new synthesis of scientific datasets, for fulldome display. The objective is to map as many types of datasets as possible into a spherical volumetric visualisation of the world's oceans. Hopefully something interesting will emerge - it's blue sky stuff.
