A better way to study ocean currents      (via sciencedaily.com)     Original source 

Computer scientists and oceanographers developed a machine-learning model that generates more accurate predictions about the velocities of ocean currents. The model could help make more precise weather forecasts or effectively predict how oil will spread after a spill.

Is it an ant? Is it a plant? No, it's a spider!      (via sciencedaily.com)     Original source 

A species of tiny, colorful jumping spider employs two lines of defense to avoid being eaten: camouflaging with plants and walking like an ant. Researchers report that this combination of camouflage and movement mimicry helps the spiders evade spider-eating spiders but does not deter hungry praying mantises.

About 13,000 years ago, the water outflow from the Mediterranean to the Atlantic Ocean was twice that of today’s      (via sciencedaily.com)     Original source 

About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across the Mediterranean basin, which had a major impact on terrestrial and marine ecosystems. But what do we know about the impact of this climate change on water circulation in the Mediterranean?

Joro spiders aren't scary: They're shy      (via sciencedaily.com)     Original source 

Despite their intimidating appearance, the giant yellow and blue-black spiders spreading across the Southeastern U.S. owe their survival to a surprising trait: They're rather timid. The Joro spider may be the shyest spider ever documented.

We now know exactly what happens in nature when we fell forests      (via sciencedaily.com)     Original source 

Deforestation is the biggest threat to the planet's ecosystems, and new research has now mapped out exactly what happens when agriculture replaces forestry.

Global warming puts whales in the Southern Ocean on a diet      (via sciencedaily.com)     Original source 

In the autumn, when right whales swim towards the coasts of South Africa, they ought to be fat and stuffed full. But in recent years, they have become thinner because their food is disappearing with the melting sea ice.

Hammerhead sharks hold their breath on deep water hunts to stay warm      (via sciencedaily.com)     Original source 

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.

Researchers discover a cause of rapid ice melting in Greenland      (via sciencedaily.com)     Original source 

While conducting a study of Petermann Glacier in northwest Greenland, researchers uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could mean that the climate community has been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration.

Plastic can drift far away from its starting point as it sinks into the sea      (via sciencedaily.com)     Original source 

Discarded or drifting in the ocean, plastic debris can accumulate on the water's surface, forming floating islands of garbage. Although it's harder to spot, researchers suspect a significant amount also sinks. In a new study in ACS' Environmental Science & Technology, one team used computer modeling to study how far bits of lightweight plastic travel when falling into the Mediterranean Sea. Their results suggest these particles can drift farther underwater than previously thought.

Vanishing glaciers threaten alpine biodiversity      (via sciencedaily.com)     Original source 

With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.

Indo-Pacific corals more resilient to climate change than Atlantic corals      (via sciencedaily.com)     Original source 

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.
