The ocean is vast and full of sounds. Many are naturally occurring, while others are anthropogenic. When these anthropogenic sounds are unwanted, they are called noise. The U.S. Bureau of Ocean Energy Management (BOEM) manages energy and mineral resource development on the Outer Continental Shelf subject to environmental safeguards, and noise is high on the list of issues to protect ocean life. BOEM has launched the Center for Marine Acoustics to further understanding of noise

New research led by the U.K. National Oceanography Centre (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behavior of submarine channels. These underwater channels are the offshore equivalents of rivers, but can be much larger. Submarine channels can extend for tens to thousands of kilometers offshore, providing an important conduit for the transfer of sediment,

After intense R&D investment, underwater acoustics specialist RTSYS has released the long-lasting and cost-effective SYLENCE-LP acoustic recorders. Two recorders were developed: a smaller one named SYLENCE-LP 220 (22 cm high, 35 days of autonomy), with one fixed hydrophone; and a longer one named SYLENCE-LP 440 (44 cm high, up to 180 days of nonstop recording), with one fixed or loose hydrophone. These recorders

A hybrid ROV developed by Woods Hole Oceanographic Institution (WHOI) took the first known automated sample performed by a robotic arm in the ocean. Last month, an international team of researchers used one of WHOI’s underwater robots, Nereid Under Ice (NUI), to explore Kolumbo volcano, an active submarine volcano off Greece’s famed Santorini island. “For a vehicle to take a

By Kayla Matthews Drones that fly above the ground are commonplace today. This technology is bought by hobbyists, deployed by the military and used for crop monitoring by farmers, for example. Drones in the water, on the other hand, are extremely valuable but often overlooked in the public eye. Here are four likely trends and applications for maritime drones in
