Monkfish Sits on Geometric Columnar Basalt
ROV Hercules captured this footage of stunning deep sea columnar basalt while diving on ancient volcanos around 1,700 meters deep in a canyon North of Molokai. Basalt is an igneous rock that, as lava, cools in a particular way that creates these unique hexagonal columns. Keep watching, and you’ll even glimpse a monkfish (also known as a goosefish) sitting on these geological wonders. These anglerfishes in the family Lophiidae are always crowd-pleasers due to their “grumpy” looking facial expressions.
The Hawaiian Islands are part of the oldest, longest, and most remote island chains on Earth, and have been a key natural laboratory for many important scientific discoveries. This 14-day telepresence-enabled expedition (NA156) is conducting ROV surveys across some of the most dramatic deep-sea habitats surrounding the Main Hawaiian Islands, and testing a new wide-field camera array system across a wide range of complex topographical features.
In October, we return to ROV dives continuing our work to advance technology use in the deep sea. Experimenting with deploying a new camera technology, we will explore using a new wide-field camera array on ROV Hercules to capture three-dimensional stereoscopic imagery from the seabed.
