Oceans

Quebec’s Magdalen Islands in the Gulf of St. Lawrence are at the mercy of rising sea levels and increasing storm surges. The fragile dunes, lagoons, marshes, and sandstone cliffs are all at risk of being lost.

The Sea Is Slowly Consuming Quebec’s Magdalen Islands

Those living in the doomed paradise face a stark choice: resist, adapt, or give in to the ravenous ocean

On Calvert Island, British Columbia, the subtle rock line of an extant clam garden is a reminder of how Indigenous peoples turned the sea into a shellfish garden.

How Indigenous Sea Gardens Produced Massive Amounts of Food for Millennia

Communities created bountiful food without putting populations at risk of collapse

Satellite image of the “milky seas” event that occurred near the coast of Java in August 2019.

First Images of Mysterious ‘Milky Seas’ Captured

Bioluminescent bacteria are likely responsible for this rare luminous event covering thousands of square miles of ocean

Researcher David Webster of the University of North Carolina Wilmington prepares the bones of an Atlantic gray whale for transfer to the National Museum of Natural History.

Scientists Find Most Complete Atlantic Gray Whale Skeleton Ever

The fossil, uncovered in North Carolina, shows signs of butchering

Sea turtles, such as olive ridleys and loggerheads, spend most of their time just below the ocean’s surface—the perfect place to collect data for tropical cyclone forecasting.

Tagged Turtles Are Helping Scientists Predict Cyclones

In the southeast Indian Ocean, turtle-borne sensors are filling in the gaps researchers need to forecast storms

Manx shearwaters breed on islands in the North Atlantic where they make nests in underground burrows.

This Seabird Species Dives Deeper When the Water is Clearer

Scientists suggest that cloudier waters, caused in part by climate change, could make it harder for Manx shearwaters to catch fish

Brooding requires a significant sacrifice for a mother Bathyteuthis berryi. Though she can't feed or quickly escape from predators while carrying her eggs, she can ensure her young stay in water that has the right temperature, salinity and oxygen levels.

Watch a Deep-Sea Squid Carry Hundreds of Pearl-Like Eggs

Footage taken 56 miles off California’s coast documents rarely-observed brooding behavior

A model of an oarfish

Rare Oarfish Caught on Video on Great Barrier Reef

This is the first record of the species on the eastern seaboard of Australia

Researchers say photo recognition could help scientists learn more about how seals move around.

Introducing Facial Recognition Software for Seals

A neural network, trained using thousands of photos of harbor seals, offers a noninvasive way of telling the pinnipeds apart

Struvite is a nuisance for wastewater treatment plants, as it can clog pipes and lines. But the crystal, which is high in phosphorous, nitrogen, and magnesium, makes an excellent slow-release fertilizer for seagrass.

Human Pee Might Just Be the Key to Saving Seagrass

Treating wastewater creates struvite—a nutrient-rich crystal that bolsters struggling seagrass beds

Women Who Shaped History

Mary Sears’ Pioneering Ocean Research Saved Countless Lives in WWII

Allied victory in the Pacific depended on strategy, bravery and military might. It also depended on a brilliant marine scientist from Massachusetts

Glowing green waters surrounded a boat in the Arabian Sea.

What Causes Swaths of the Ocean to Glow a Magnificent Milky Green?

A sailor who witnessed the rare phenomenon in person and a scientist who saw it from the sky team up to learn about the ghostly light

The bacterium, roughly the shape and size of an eyelash, was first discovered in 2009 in the mangrove swamps of Guadeloupe, an island in the Lesser Antilles. The bacteria appeared as long translucent centimeter-long strings on decaying leaf matter in the water.

World’s Largest Bacterium Discovered in Caribbean Mangrove Swamps

The bacterium is the size of an eyelash and visible to the naked eye

A skeleton of the giant Triassic ichthyosaur Shonisaurus popularis hangs in the Nevada State Museum.

Whale-Sized Marine Reptiles Once Ruled the Seas

Paleontologists are beginning to learn how and why ichthyosaurs evolved into giants

Royal kombu (aka sugar kelp) harvested from the Netherlands’ first organic seaweed farm enriches and flavors the Dutch Weed Burger’s soy-chip-based patty.

Innovation for Good: Game Changers

Is Seaweed the Next Big Alternative to Meat?

From kelp burgers to bacon of the sea, sustainable food entrepreneurs are innovating to charm hungry omnivores

Fish like Epinephelides armatus, also known as breaksea cod, tend to be rated as uglier than fish like Holacanthus ciliaris, or queen angelfish.

Ugly Fish Need Love, Too

New research finds that less attractive reef fish are more likely to be threatened

The Thwaites Glacier in Antarctica

Antarctica’s ‘Doomsday Glacier’ Melting at Fastest Rate in 5,500 Years

Researchers used penguin bones and shells to track ice loss in the Thwaites and Pine Island glaciers

The Earth’s oceans have risen and fallen over the millennia. But they have, on average, been relatively stable over billions of years. The balance of the deep water cycle—the exchange of water between the Earth’s surface and its interior—has an important role to play in maintaining that stability.

How the Earth’s Mantle Sends Water Up Toward the Surface

A new model suggests “mantle rain” ensures we will always have a surface ocean

Korora, the world’s smallest living penguin

Hundreds of Little Blue Penguins Are Turning Up Dead in New Zealand

Rising ocean temperatures are likely causing the flightless birds to starve to death

New research shows how seals use their whiskers to aid them as they hunt. 

Seals Use Their Whiskers to Help Hunt in the Deep Ocean

New video footage shows rhythmic whisker movements that have never been observed before in seals in the wild
