    Shallow reef species may not find refuge in deeper water habitats

    Deep water reefs are unlikely to be safe harbors for many fish and coral species from shallow reefs threatened by climate change and human activity. Shallow water creatures may have trouble adapting to conditions in the deep, scientists report in the July 20 Science. Plus, deep reefs are facing the same threats that are putting shallower ones at risk.

    The study deals a blow to the “deep...

    New ‘Poké Ball’ robot catches deep-sea critters without harming them

    Like a submarine Poké Ball, a new robotic device gently captures and releases deep-sea creatures without a scratch. This critter catcher could be decked out with cameras and other sensors to give scientists an unprecedented view of life in one of Earth’s most mysterious environments. 

    The contraption, designed to be mounted on a remotely operated underwater vehicle, folds into a 12-sided...

    An ancient swimming revolution in the oceans may have never happened

    About 540 million years ago, the oceans were an alien landscape, devoid of swimming, or nektonic, creatures. Some scientists have hypothesized, based on fossil evidence, that swimmers suddenly dominated in the oceans during the Devonian Period, between 419 million and 359 million years ago. But an in-depth study of marine fossils now suggests that this so-called Devonian Nekton Revolution...

    Bird poop helps keep coral reefs healthy, but rats are messing that up

    When invasive rats chow down on island seabirds, coral reefs suffer.

    Researchers studied islands with and without the rodents in the Chagos Archipelago in the Indian Ocean. On rat-free isles, there were on average 1,243 birds per hectare compared with about two birds per hectare on rat-infested islands, the team found. And these rodentless islands had healthier coral reef ecosystems. The...

    Underwater fiber-optic cables could moonlight as earthquake sensors

    The global network of seafloor cables may be good for more than ferrying digital communication between continents. These fiber-optic cables could also serve as underwater earthquake detectors, researchers report online June 14 in Science.

    “It’s a very exciting proposition,” says Barbara Romanowicz, a seismologist at the University of California, Berkeley and the Collège de France in...

    Here’s what narwhals sound like underwater

    Narwhals are among the most elusive of whales. But for the first time, researchers have been able to eavesdrop on the creatures for days at a time as these unicorns of the sea dove, fed and socialized.

    Biologist Susanna Blackwell and colleagues listened in on the clicks, buzzes and calls of the East Greenland narwhal (Monodon monoceros). The team’s findings, published June 13 in PLOS ONE...

    Antarctica has lost about 3 trillion metric tons of ice since 1992

    Antarctica is losing ice at an increasingly rapid pace. In just the last five years, the frozen continent has shed ice nearly three times faster on average than it did over the previous 20 years.

    An international team of scientists has combined data from two dozen satellite surveys in the most comprehensive assessment of Antarctica’s ice sheet mass yet. The conclusion: The frozen...

    Tropical cyclones have slowed over the last 70 years

    Tropical cyclones don’t move as fast as they used to.

    The fierce, swirling storms move 10 percent slower, on average, than they did nearly 70 years ago, a new study finds. Such lingering storms can potentially cause more damage by dumping even more rainfall on land beneath them.

    Atmospheric scientist James Kossin examined changes in how quickly tropical cyclones, known as...

    The Chicxulub asteroid impact might have set off 100,000 years of global warming

    After a giant asteroid hit Earth about 66 million years ago, the planet’s climate went on a roller coaster ride.

    The space rock’s impact set off tsunamis and wildfires before climate-chilling clouds of sulfur gas engulfed the planet for decades, wiping out most life (SN: 11/25/17, p. 14). As these clouds dissipated, billions of tons of carbon dioxide, which spewed into the atmosphere...

    Bull sharks and bottlenose dolphins are moving north as the ocean warms

    Far from their usual tropical waters, some 200 bottlenose dolphins and about 70 false killer whales have been spotted off the western coast of Canada’s Vancouver Island. Over on the Atlantic coast, bull sharks have turned a North Carolina estuary into a nursery — a sight more familiar in Florida, until now.

    Two new studies highlight the unusual northern sightings of these three ocean...
