Integrating bathymetry, weather, and diverse oceanographic data sets with your own data opens up new realms of discovery and helps to reveal unexpected relationships in the systems you study. But do you know where to find the right data for your analyses? This directory contains links to free, open source and public domain geospatial data sets to augment your work.
