Earth is currently experiencing an occurrence of the El Niño climate pattern.

Could We Mitigate Super El Niños by Artificially Changing the Climate? A New Study Indicates Yes

Researchers used computer models to see what would have happened had scientists caused marine cloud brightening in the face of strong past El Niños

Scientists analyzed about 25 years' worth of data from the Fram Strait, a passageway where the Arctic and Atlantic oceans meet.

The Arctic Ocean May Have Passed a Crucial Tipping Point That Could Harm Food Webs and Worsen Climate Change

Sea ice loss seems to have triggered a decline in the nutrient nitrate, affecting the tiny organisms that form the foundations of marine food chains and absorb atmospheric carbon dioxide, according to a new study

Scientists think sperm whales entered the Mediterranean Sea via the Strait of Gibraltar roughly 20,000 years ago, then began to spread east.

Sperm Whales Living in the Eastern Mediterranean Sea Seem to Have Developed a Distinct Dialect From Those in the West

All Mediterranean sperm whales were thought to be part of one cultural group, identifiable by a unique pattern of clicks, or a coda. But sound recordings suggest that eastern creatures use a sped-up version of the western whales’ coda

Strange, metallic-looking spheres recently washed ashore in Queensland, Australia.

Strange Spheres Washed Ashore on an Australian Beach. Authorities Say They’re Probably ‘Space Balls’—Empty Fuel Vessels From a Rocket

The shiny objects—each roughly twice the size of a basketball—began to appear on July 3. Authorities initially worried that they were hazardous but have since determined that they’re likely safe bits of space junk

Two dolphins swim up to the camera. The recognized images from this year's Ocean Conservancy Photo Contest all feature animals.

These 11 Wildlife Images From the Ocean Conservancy’s Photography Contest Showcase the Wonder of Earth’s Waters

Ernest Shackleton, Robert Falcon Scott and Edward Adrian Wilson on the British National Antarctic Expedition, also known as the Discovery Expedition, on November 2, 1902.

A New Expedition Will Create 3D Digital Twins of Polar Shipwrecks Tied to Voyages of Rival Explorers Who Raced to the South Pole

Robert Falcon Scott led an expedition aboard the ship ‘Terra Nova’ and Ernest Shackleton led one from the ship ‘Quest’—but neither explorer got to plant the first flag in the heart of Antarctica

The "cold blob," shown in blue near the top, is also called the Atlantic "warming hole."

As the Ocean Warms, a ‘Cold Blob’ in the Atlantic Has Puzzled Scientists. It Might Be a Warning Sign About a Key Current System

A patch of water south of Greenland and Iceland has cooled by nearly 1.8 degrees Fahrenheit since 1900. A new study suggests that it shows a crucial system of ocean currents is weakening, which could alter Earth’s climate

A North Atlantic right whale swims with dolphins around its head in the Stellwagen Bank National Marine Sanctuary east of Boston.

Speed Limits for Ships Protect Endangered Right Whales From Vessel Strikes. Could the Animals Survive Without Them?

Since 2008, rules requiring ships to slow down to avoid collisions with North Atlantic right whales have reduced fatalities of the critically endangered animals. Now, NOAA is calling the regulations into question, raising concerns for the mammals’ future

The technology uses thermal cameras and artificial intelligence to detect whales based on the water spewed from their blowholes, which is slightly warmer than the surrounding water.

Gray Whales Are Getting Struck by Ships in San Francisco Bay. Could This New A.I.-Powered Tech Save Them?

The recently launched system involves two thermal cameras that can detect gray whales up to four miles away, giving ships enough time to slow down or change course—and avoid running into the marine mammals

A coral reef in the southern Andaman Sea, in Southeast Asia

Scientists Identify Swaths of Coral Reefs That Might Be Able to Withstand Climate Change, Offering New Avenues for Conservation

New research has mapped more than 64,000 square miles where the crucial habitat seems to be somewhat protected from the impacts of the warming ocean

Animation showing the surface water temperature changing in the Pacific Ocean from January 1 through June 8.

The ‘Super’ El Niño Has Arrived. Here’s How It Might Affect the World’s Weather and Economy

The naturally occurring climate pattern, characterized by warm surface water in the Pacific Ocean, that has just started could be one of the strongest ever recorded, according to experts

Goblin sharks have elongated snouts and extendable jaws, which they use to snatch prey.

‘Ugliest Shark on the Planet’: See the Elusive Goblin Shark, Filmed for the First Time in Its Deep-Sea Habitat

Scientists spotted the enigmatic creatures in 2019 and again in 2024, marking the first times they’ve been observed alive in the wild. The sightings drastically expand the animals’ known geographic and depth range

Scientists explored a tiny portion of the site during more than 30 dives with a submersible.

Scientists Discover the World’s Largest, Deepest Whale Graveyard, Where Cetacean Remains Have Been Piling Up for Five Million Years

The massive necropolis, located deep in the southeastern Indian Ocean, is teeming with marine life supported by the whale carcasses, including many suspected new species

The new species was named Microeledone galapagensis ​​​​​​in honor of the location where it was collected.

Cool Finds

‘Cute Little Guy’: Scientists Discover a Tiny Blue Species of Octopus by the Galápagos Islands

The palm-size creature was spotted and collected during a research expedition more than a decade ago, but scientists have just identified it as a previously undescribed species

Many of the delicate ceramics are still intact.
