Researchers in the Arctic have recorded audio data of narwhals hitting deep-sea hydrophones. Although they aren’t entirely sure what might be causing them to investigate the microphones so closely, the findings could raise questions around whether marine animals are disturbed by underwater acoustic monitoring in some way.  The ocean is a huge place and it’s impossible for researchers to find ways of …

Antarctica’s bays look calm from the surface. Down below, that calm hides scars. When large vessels stop in shallow Antarctic waters, many of them still drop heavy anchors attached to long chains. Wind and currents nudge a ship around, and the chain drags arcs across the bottom. A new study documented what that looks like in Antarctic waters and why …

In the world of stratigraphy, or rock layers, superficial sediments are usually younger than the deeper ones they settle upon. The North Sea, however, has revealed giant mounds of sand that defy this geological principle on a scale scientists have never seen before. Researchers from Norway and the UK have identified hundreds of sand bodies under the North Sea that …

A marine biologist has shared a glimpse into how epaulette sharks get around – using their pectoral and pelvic fins to walk along the seafloor.  “And that is why they are called ‘walking sharks’,” says Jacinta Shackleton on Instagram. Shackleton captured the remarkable video of a juvenile epaulette shark (Hemiscyllium ocellatum) exploring the reef while she was working at Lady Elliot Island eco resort on …
