US Exits Search for ARA San Juan

The U.S. Navy said it has begun to wind down operations as part of the international search for the still-missing Argentine submarine A.R.A. San Juan that vanished in the South Atlantic in mid November. The U.S. joined the Argentina-led multinational search efforts within 24 hours of learning of the missing submarine on November 17, and is now drawing down, having twice swept the search areas assigned by the Argentine Navy with advanced sensors.

The conference program gets under way on Tuesday…

Scientists Study Largest Underwater Volcanic Eruption

In July 2012, airline passengers flying over the Southwest Pacific Ocean spotted a large and unusual object floating on the water’s surface. That object, which turned out to be a giant raft of pumice, was evidence that an underwater volcanic eruption had occurred. And as the raft continued to grow to roughly the size of Philadelphia, scientists observed that the eruption was extraordinarily large.

Biofouling Foiled: UV Light Harnessed for Biofouling Control

Since the first deployment of in-situ monitoring instrumentation, biofouling has been a problem. Without an effective solution, people have historically had to accept the limits biofouling imposes on ocean sensing work, with significant repercussions. When instrumentation is deployed in-situ, the value of the data taken during the deployment corresponds with the longevity: information gleaned from a longer deployment is often more useful than information from one of a shorter term.

UN Oceans Conference: The High Seas Treaty

While many countries have agreed to take steps to protect the vast, ungoverned swathes of the world's oceans, they have yet to see their High Seas Treaty go into effect. This week's U.N. Oceans Conference in the French city of Nice hopes to change that.WHAT IS THE HIGH SEAS TREATY?The treaty, signed in 2023, provides a legal framework for creating marine protected areas on the "high seas", or the ocean areas that lie beyond any national jurisdiction.Currently…

Soil Research Unearths Collecting Point for Plastics

Collaborative research team, led by KAUST scientists, reveals a history of plastic sequestration in mangrove ecosystems.Global plastic production began to rise precipitously around 1950. Since that time production has grown at around 8.5% annually. Unfortunately, due to poor recapture and recycling globally, much of that plastic has ended up in the world’s oceans.Strangely, locating plastic with surveys of the world’s oceans has proven difficult.

Magnetic Fossils May Reveal Eels’ Internal GPS System

Microscopic magnetic fossils found in North Atlantic seafloor sediments may represent components of an internal "GPS system" for an ancient marine creature that used Earth's magnetic field to navigate long distances, according to scientists.The researchers said the fossils - about 50 times smaller than the width of a human hair - are made of a strongly magnetic iron-bearing mineral called magnetite.
