At some 4,700 feet beneath the sea, marine scientists filmed a shrimp spew glowing matter, or bioluminescence, from its mouth.
Whale watching is generally regarded as innocent fun. Unlike an aquarium park, whale watching boats take you to see majestic animals that remain free in their natural habitat.
The data available to produce the definitive map of the world’s ocean floor has more than doubled, just two years after the launch of an international effort to produce a complete map by the year 2030. Following the efforts of The Nippon Foundation-GEBCO Seabed 2030 Project, coverage of the world’s ocean floor has now increased from 6% to 15%.

The numbers are bananas. Or, to be more accurate, they’re turtles. Or still, embryos. Regardless, as of noon Friday the best-available statistics showed 1,857 sea turtle nests with more than 70,700 estimated eggs laid on the Georgia coast — a staggering number for this point in the nesting season.
It all started here at the historic Scripps Institution of Oceanography Pier at La Jolla, the long long-term carbon dioxide (CO2) level monitoring program, like so many other oceanographic, atmospheric and biological studies they have conducted over the many decades.

In the Canadian Arctic, layers of permafrost that scientists expected to remain frozen for at least 70 years have already begun thawing. The once-frozen surface is now sinking and dotted with melt ponds and from above looks a bit like Swiss cheese, satellite images reveal.
Scientists at London Zoo are investigating after a rare pygmy sperm whale was found washed up on a Welsh beach on Wednesday.
With significant coastal populations and property at stake, two new studies by NOAA’s National Centers for Environmental Information (NCEI) and its research partners focus on the behavior of tropical cyclones.

The tube anemone Isarachnanthus nocturnusis only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923?base pairs. The human mitochondrial genome (mitogenome), for example, comprises 16,569 base pairs.
This map by researchers at Dalhousie University, in Halifax, Nova Scotia, predicts the coverage of Gulf Coast waters by low-oxygen conditions on July 27. The thick black line shows the limits for the most probable areas showing hypoxic conditions. The university’s forecast actually calls for the hypoxia zone to expand to more than 10,000 miles in August, if no tropical weather causes mixing.
Narratives help frame our thinking and action. On the eve of World Oceans Day and in anticipation of the United Nations Decade of Ocean Science for Sustainable Development (2021–2030), a new narrative for the ocean is warranted—one that reflects current scientific knowledge and inspires new science and effective action.

Every spring, millions of ducks touch down on Yukon Flats National Wildlife Refuge, a spread of muskeg and dark water the size of Maryland. These days, more ruddy ducks seem to be among them. Recent sightings of this handsome, rust-colored bird — the males with a teal-blue beak — suggest ruddy ducks are moving farther northward.

Wind has shaped the face of Mars for millennia, but its exact role in piling up sand dunes, carving out rocky escarpments or filling impact craters has eluded scientists until now.
Tiger sharks have a reputation for being the 'garbage cans of the sea' -- they'll eat just about anything, from dolphins and sea turtles to rubber tires. And in a new study, scientists just discovered that baby tiger sharks eat birds. And not seabirds like gulls or pelicans -- familiar backyard birds like sparrows, woodpeckers, and doves. In short: Baby sharks, doo doo doo doo doo doo They eat birds, doo doo doo doo doo doo
In this study, two 50 m segments of dune on an intermediate beach were monitored monthly with a terrestrial lidar scanner. Topographic changes and vegetation coverage were quantified at high spatial resolution (0.1 m in the alongshore and cross-shore dimensions) and used to investigate dune response to a series of major tropical and extratropical storm events.

Officially, of course, the Atlantic hurricane season does not begin until June 1.
Future sea level rise (SLR) poses serious threats to the viability of coastal communities, but continues to be challenging to project using deterministic modeling approaches. Nonetheless, adaptation strategies urgently require quantification of future SLR uncertainties, particularly upper-end estimates.
ANCHORAGE (KTUU) - A second gray whale has been found dead, making it the third whale found in just a few weeks in Alaska. This time the carcass was found near Cordova. At least 60 gray whales have been reported stranded dead along the west coast, during their spring migration from Mexico to Alaska. Of those necropsied, many were found to be skinny and malnourished.

In the world’s deepest diving operational submersible, the 'Limiting Factor', Victor Vescovo and his team completed the fourth mission of the expedition to reach what is commonly known as the deepest point on planet Earth: Challenger Deep within the Mariana Trench. Victor Vescovo set a new deep-diving record with this achievement.

Ryan Lawler saw the dorsal fin in the distance, swaying slowly side to side, and assumed it was a great white shark. As his boat got closer, he saw the massive fish's snout sticking out of the water, its mouth wide open.
It was another cold season full of records in Alaska, mostly of the abnormally warm kind. The state is in the midst of a five-plus-year onslaught of extreme warmth, only infrequently broken by the customary cold. This year’s warm season has begun on the same foot.
The Arctic sea-ice decline is among the most emblematic manifestations of climate change and is occurring before we understand its ecological consequences. We investigated future changes in algal productivity combining a biogeochemical model for sympagic algae with sea-ice drivers from an ensemble of 18 CMIP5 climate models.
