One of my more popular posts, based on site stats, is this one highlighting a nice image of the seafloor in the region of the Puerto Rico trench. This week’s Sea-Floor Sunday image shows a new bathymetric image of this region that I found on the USGS Woods Hole Science Center website.
Click on the image above (or here) to read the description from the researchers who acquired the data.
Below is another image from this dataset – this one is zoomed in a bit and also reoriented (north is to the lower right).
Click on the image to go to the page that describes the features shown here and a key to the annotation. The ‘amphitheaters’ refer to areas of geologically recent submarine landslides (note the possible debris fans at the base of slope; one of them outlined with a black dashed line).
