Sea-Floor Sunday #61: Kolumbo submarine crater
This week’s Sea-Floor Sunday image is of a submarine volcanic complex in the Aegean Sea. This image and much, much more about the geology of this area can be found on this page of the NOAA Ocean Explorer website.

I like this image because it combines bathymetric contours, color, and shaded relief all into one beautiful map. Make sure to check out the rest of the images on this page — there is also a seismic-reflection line showing the submarine pyroclastic flow deposits on the flank of the volcano.
