Could the High Seas Be Closed to Fishing?

Oceans Deeply – Momentum is growing for a radical yet potentially realistic proposal to close international waters to commercial fishing. The idea first began to snowball in 2014, and since then more and more scientists and conservationists have joined the call to transform the high seas – the ocean beyond the national jurisdiction – into an enormous marine reserve. Fishing interests Read More…

Magnets Help Keep Sharks Out of Fish Traps

Smithsonian – Sharks are having a rough go of it. It’s estimated that humans kill 100 million sharks of all species each year, many hunted for shark-fin soup while others are killed as bycatch when fishermen accidentally hook or trap them. While there’s a lot of work to be done to save sharks, Ben Millington at the Australian Broadcasting Network reports that researchers have come up Read More…

Researchers may be on brink of solving deadly red tides

CBS News – Researchers in southwest Florida think they've found a solution to the red tides that have killed millions of sea animals, CBS Miami reports. Scientists from Mote Marin Laboratory are testing a system in a canal near Fort Myers. Two pumps installed on the canal mix water with ozone, which removes toxins. The system, which can process 300 gallons of water a minute, is already Read More…

A Collaborative Approach to Mapping Marine Megafauna Movements

Journal of Animal Ecology – The understanding of the interplay of movement, behaviour and physiology that biologging offers has applied relevance for a range of fields, including evolutionary ecology, wildlife conservation and behavioural ecology. In recognition of this, the Journal of Animal Ecology has an upcoming Special Feature on Biologging  (submissions due 20th September). One Read More…

Robots with lasers could help explain ‘mysterious’ spotted sharks…

The Charlotte Observer – Sand tiger sharks swerve slowly, sinuously around a shipwreck among schools of hundreds of glittering silver fish, video gathered by a robot shows. They don’t appear fazed by a swimming robot pointing laser beams in their direction. Avery B. Paxton is the lead researcher on a project using marine robotics and lasers to study sand tigers — a species of shark Read More…

Island south of Tokyo could hold clues to future acidified oceans

The Asahi Shimbun – An underwater carbon dioxide (CO2) vent site near an island 160 kilometers south of central Tokyo could provide vital information for University of Tsukuba researchers who are studying the impact of ocean acidification. The ocean is being acidified with the rising CO2 concentration in the atmosphere, and there is a growing interest in the scientific community in how Read More…

Most Marine Mammals Are Missing One Mysterious Gene

National Geographic – Millions of years ago, ancient land-dwelling mammals returned to the sea. Their bodies became streamlined for swimming, articulated fingers turned into flippers and fins, hypnotic songs slowly filled the oceans—and, somewhere during the evolutionary process, the newly evolving marine mammals lost a particular gene called Paraoxonase 1, or PON1. Perhaps that Read More…

Good News for These Hawaiian Dolphins (That Look an Awful Lot Like…

NRDC – False killer whales are cetaceans with an identity crisis. They may resemble Shamu in some ways, but the blimp-shaped, spiny-toothed predators are actually dolphins. A small population of them in the waters off Hawaii is facing a conservation crisis, too. Just around 150 remain. But there’s hope yet: The population can now say aloha to new habitat protections. Responding to Read More…

Scientists search for ‘smoking gun’ in the dead zone of…

CNN – On a good day, a beach trip to Sarasota or a boat trip out of Fort Myers can be a sun-kissed adventure filled with relaxation and anticipation. These are not good days. The infamous "red tide" has turned southwest Florida into a tragic dead zone with miles of deserted beaches and boatfuls of dread. The worst toxic algae bloom in recent memory is plaguing paradise and no one has Read More…

Deglacial Changes in Western Atlantic Ocean Circulation

Lab Manager – A new study carried out by an international team of researchers, using the chemistry of ocean sediments, has highlighted a widespread picture of Atlantic circulation changes associated with rapid climate change in the past. The new integrated dataset, published today in the journal Nature Communications, provides new insights into the interactions of melting ice, ocean Read More…
