Mapping the Ocean Floor

The School of Geosciences at Sydney University has released the first interactive map of seafloor geology. Seafloor Lithology allows you to explore seafloor lithologies based on nearly 14,500 samples taken from the world's seas and oceans.

Seafloor Lithology includes three different map views: an interactive 2d map, an oblique map projection (which allows you to view seafloor elevation) and a 3d Cesium globe view. The 3d globe view also allows you to explore the topography of the seafloor (use ctrl & the left mouse button to rotate the camera view around a point).

The map key explains the colors used for the seafloor's different geologies. The map key is a little small but if you click on the key it will open in a legible size in a separate window.
