Light
There’s no light in the deep sea, so we have to bring our own. New lighting on remotely operated vehicles Deep Discoverer and Seirios will enable better illumination of marine life and seafloor features. Here, the lights on Deep Discoverer shine on a spectacular bow-shaped, headwall scarp during Océano Profundo 2015: Exploring Puerto Rico’s Seamounts, Trenches, and Troughs expedition.
