Oceans

Researchers found evidence of degenerative joint disease, trauma and other health problems.

Whalers Didn’t Just Sing Sea Shanties and Seek Adventure. Proof of Laborers’ Grueling Work Is in Their Skeletons, Buried in the Arctic

Remains buried on Svalbard show the brutal toll whaling took on men in the 17th and 18th centuries. Climate change threatens these kinds of archaeological sites across the Arctic

Tuerkayana hirtipes, a true crab species examined in the study

When Did Crabs Evolve Their Iconic Sideways Scuttle? Scientists Traced It to a Common Ancestor That Lived 200 Million Years Ago

The findings suggest that their famous lateral movement evolved just once. It may have helped the animals rapidly spread and diversify because moving in two directions meant they could easily escape predators

Sweetgrass basket weaving is one of the most enduring cultural traditions of the Gullah Geechee people, descendants of Africans enslaved on the rice, indigo and cotton plantations of the southeastern United States.

From Basket Weaving to Oyster Reef Conservation, Gullah Geechee Women Are Preserving a Living Heritage

Along America’s southeastern coast, descendants of enslaved Africans pass down traditions and knowledge of crafts, ecology and food through generations

Each by-the-wind sailor is made of a community of genetically identical organisms called "zooids" that perform different tasks.

Millions of Bright Blue Blobs Called ‘By-the-Wind Sailors’ Are Littering Beaches Along the West Coast

The strange creatures are washing up on shores across California, Oregon and Washington this spring—and making the coast smell especially fishy

Remoras might dive into manta rays' rear ends when they're scared.

This Fish Hitches Rides in Manta Rays’ ‘Buttholes,’ According to New Research

Scientists suspect that the behavior could harm the manta rays, suggesting a complex relationship between remoras and their hosts that can sometimes be parasitic

The Bering Strait is a narrow waterway between Russia and Alaska that connects the Pacific and Arctic oceans.

Could Building a Dam Across the Bering Strait Save the Planet From Some Effects of Climate Change?

A preliminary study suggests that blocking off the waterway between Russia and Alaska could help the survival of a key system of ocean currents. But there could be potential unforeseen consequences, particularly to marine ecosystems

Scientists used acidic and basic solutions to trigger chemical reactions in algae.

These Marine Algae Glow When Waves Disturb Them. Their Bioluminescence Could Power Electricity-Free Lamps of the Future

The single-celled organisms usually shimmer for mere milliseconds, but researchers figured out how to sustain their illumination. The technology could one day be used to light robots’ ways in the deep sea or space

Sue Schubel hand-paints around 500 a year from her workshop in a converted barn steps from the ocean in Bremen, Maine, a tiny town in the lower third of the state’s craggy coast.

How ‘Seabird Sue’ Blends Art and Science to Attract Birds Back to Lost Habitat

For the past decade, Sue Schubel has been making detailed decoys of terns, puffins and other seabirds to entice real ones to restored or new homes

Chonkers, a Steller sea lion, is much larger than his companions, California sea lions.

Chonkers the Massive Sea Lion Drew Crowds to San Francisco’s Famed Pier 39. Then, a New Chunky Showstopper Stole His Identity

The Steller sea lion was an unusual visitor to the pier, which typically hosts smaller California sea lions. However, he may have moved on days ago, during which time a humongous member of the area’s more common species tricked onlookers

During World War I, the Tampa protected convoys from submarine attacks.

Divers Discover the Shipwreck of a World War I-Era Coast Guard Cutter, Which Vanished With 131 Sailors on Board in 1918

The wreckage of the “Tampa,” which was torpedoed by a German submarine, was found 50 miles off the coast of Cornwall, England. The disaster was the largest single American naval combat loss of life during the war

Members of the rescue team on a barge that later transported the whale to the North Sea

Timmy the Whale Was Released Into the North Sea After Being Stranded Off the German Coast for Weeks. Was That the Right Call?

The humpback whale first entered shallow water at the end of March, but its health deteriorated over the past few weeks. Experts have criticized efforts to rescue the animal, which may have done more harm than good

The MV Hondius, the cruise ship facing a hantavirus outbreak, anchored off the coast of Cape Verde, an archipelagic country near West Africa

A Deadly Outbreak of Hantavirus Has Stranded a Cruise Ship in the Atlantic Ocean. Here’s What to Know About the Rare Contagion

Three people associated with the vessel have died, and health officials have identified a total of two confirmed cases and five suspected cases of the infection. The virus usually spreads via contaminated rodent droppings

What if, rather than coral reef rehabilitation remaining a tedious and difficult manual process, conservationists could harness robotics, artificial intelligence and autonomous vehicles to transform it into an industrial-scale endeavor?

Could Underwater Autonomous Robots Save Coral Reefs?

Reef restoration is a slow process, with divers planting coral fragments one at a time by hand. But roboticists are now developing automated planters that could change the game

Sea ice forms off the edge of the Brunt Ice Shelf in Antarctica’s Weddell Sea.

Warm Waters Are Usually Trapped Deep Within the Southern Ocean. Now, They’re Encroaching on Antarctica, Threatening Its Ice

Two new studies that relied on data from a fleet of diving robots show how climate change is altering ocean movements in ways that jeopardize the stability of the polar ice cap

After researchers aboard the Okeanos Explorer ship couldn't figure out the orb's identity, they sent it to the Smithsonian's National Museum of Natural History for a more thorough investigation.

Cool Finds

Scientists Found This Mysterious Golden Orb on the Seafloor Nearly Three Years Ago. Now, They Finally Know What It Is

After a long, winding road of tests, researchers at the Smithsonian’s National Museum of Natural History and other institutions determined that the strange blob once attached a large sea anemone to a rock

Cool Finds

This Bone-Crunching Octopus Was Nearly the Size of a Semitruck and May Have Feasted on Giant Reptiles 100 Million Years Ago

The massive invertebrates may have been top predators, according to an analysis of their fossilized jaws. The work suggests that ancient oceans weren’t completely ruled by spine-bearing creatures, as previously thought

The two-toned lobster will go on display at the Woods Hole Science Aquarium when it reopens next year.

See the 1-in-50-Million Split-Color Lobster Caught Off the Coast of Massachusetts. It’s Carrying Two Sets of Genetic Information

The unusual-looking crustacean is two-toned, with a line dividing its body into an orange side and a brown side. This can happen when two fertilized, unlaid lobster eggs touch—causing one to absorb the other

The reseachers investigated preserved specimens kept at museums, like this Bufoceratias wedli from the Field Museum in Chicago.

Anglerfish Are Known for Their Built-in Fishing Rods. New Research Sheds Light on How These Lures Evolved in the Strange Creatures

A new study suggests the odd appendages first appeared in the fish’s ancestors around 72 million years ago. Today, females might use them not only to attract prey but also to communicate with potential mates

Fish swim around the Antilla shipwreck.

The ‘Antilla’ Shipwreck Tells the Story of When World War II Came to Aruba

Tourists can learn about this history by snorkeling over the wreck of the German ship in shallow waters just off the island’s coast

The researchers primarily studied California two-spot octopuses.

Octopus Sex Just Got Weirder. In Addition to Depositing Sperm, Males’ Specialized Mating Arm Can ‘Taste’ Female Hormones

The hectocotylus is both a reproductive organ and a sensory organ, a rare combination in animals, new research suggests
