MIT’s search and rescue algorithm could quickly find those lost at sea

Posted on by

The MIT team set out to develop an improved method for tracking lost objects at sea by focusing on what it refers to as hidden “traps

The ocean can be a ferociously wild place, which makes locating lost people and objects a tall order for first responders. Researchers at MIT have developed a new algorithm that takes stock of ocean conditions to determine in real-time where these missing items and people are likely to appear, which could give the efficiency of search and rescue operations a big boost.

Plankton-seeking oceanographic probe plunges to the inky depths

Posted on by

As everyone knows, marine life near the surface of the ocean is much different than that which lives in the deeps. In order to get a better understanding of how those regions differ, scientists have created a biological probe that free-falls through th… Continue reading Plankton-seeking oceanographic probe plunges to the inky depths→

Why one part of the ocean bucked the trend and cooled last century

Posted on by

For the last century or more, much of Earth’s land and ocean surfaces have been steadily warming, which we now understand is a product of climate change. But in parts of the Southern Ocean around Antarctica, sea surfaces cooled considerably since the e… Continue reading Why one part of the ocean bucked the trend and cooled last century→

Deep sea expedition uncovers 30 new species, plus longest-known animal

Posted on by

Forget space – the oceans are Earth’s final frontier. Even after centuries of exploration we’re still only just scratching the surface of what lives down there. The latest case in point is a diving expedition off the coast of Western Australia, which h… Continue reading Deep sea expedition uncovers 30 new species, plus longest-known animal→

Study suggests the ocean is soaking up twice as much CO2 as we thought

Posted on by

The world’s oceans play an important role in regulating the amount of carbon dioxide in the atmosphere by absorbing billions of metric tons of it each year. A new study suggests we may have been greatly underestimating the effectiveness of this vast ca… Continue reading Study suggests the ocean is soaking up twice as much CO2 as we thought→

Underwater avalanches drive microplastic waste into the deep ocean

Posted on by

Millions of tons of plastic waste washes into the world’s oceans each year, but a new study has revealed that it doesn’t all move through the water in the same way. Scientists investigating the movement of submarine sediment have found that so-called u… Continue reading Underwater avalanches drive microplastic waste into the deep ocean→

Extremophile microbes found thriving half a mile beneath the seafloor

Posted on by

Every time we think we’ve figured out the limits of where life can exist, we discover extremophile organisms thriving under conditions we’d previously ruled out. The latest example comes from studies of rock cores drilled from the floor of the Indian O… Continue reading Extremophile microbes found thriving half a mile beneath the seafloor→

Wave-powered AUV stations could replace crewed support ships

Posted on by

Although autonomous underwater vehicles (AUVs) are electrically-powered, they’re typically launched from fuel-burning surface support vessels. A new system is being designed to replace those ships with more environmentally-friendly wave-powered underwa… Continue reading Wave-powered AUV stations could replace crewed support ships→
