After the researchers identified it as a subterranean river and gathered at the site in Antarctica, they drilled down 1640 feet below the ice's surface using a hot water hose to melt the ice.

Hidden Life Found Far Beneath World's Largest Ice Shelf

Hundreds of shrimp-like creatures were found living 1640 feet beneath Antarctica's Ross Ice Shelf

These Salt Flats in Puerto Rico Are Cotton-Candy Pink

The distinct color of Las Salinas comes from a combination of algae, bacteria, salt and water

Blue holes, like the Great Blue Hole in Belize, are vast caverns that descend into the seafloor. Sediment accumulates at the bottom of a blue hole, giving researchers a way to gauge historical hurricane activity.

Blue Holes Show Hurricane Activity in the Bahamas Is at a Centuries-Long Low

Many more powerful storms battered the region in the past

What Are Scientists Learning About the Deepest Diving Creatures in the Ocean?

Animals-turned-oceanographers are helping biologists find out what they do when they get to the cold, dark depths

The seagrass Posidonia australis.

World’s Largest Plant Is a Seagrass That Clones Itself

The 4,500-year-old plant lives off the coast of Australia

The House of Slaves on Senegal’s Island of Gorée is one of 284 significant African coastal sites included in a recent assessment of climate risk.

Climate Change Threatens Important African Coastal Sites

Dozens of important cultural, social, and ecological places are already at risk from climate hazards.

A 2015 expedition found two species of sharks living in the hot, acidic water near Kavachi, thus earning it the nickname "Sharkcano."

NASA Snaps Photos of Underwater 'Sharkcano' Erupting

Kavachi, a submarine volcano in the southwest Pacific Ocean, is home to several species of sharks and fish that can withstand the extreme environment

When a group of 360 dolphins visited corals located in the Northern Red Sea, reseachers noticed that calves under one year old would watch adults brush themselves against the coral.

Dolphins May Use Coral and Sponges as Skin Care Items

The mammals rub on invertebrates, possibly to contact substances that might work like antibacterial creams

Whale sharks are the largest fish on Earth.

Cargo Ships Are Killing Whale Sharks

New research shows these gentle giants are often on a collision course with large ocean vessels

Researchers keep finding dolls and doll body parts off the coast of Texas, where ocean currents push debris and garbage onto the beach.

Why Do Creepy Dolls Keep Washing Up on Texas Beaches?

Ocean currents push the unsettling toys—and tons of other trash—onto state shores

Over the past decade, vaquita numbers plummeted from 576 to just ten individuals because of a rise in the illegal totoaba trade.

The Population of Vaquita Porpoises Has Dwindled to Ten, but a Rebound Isn't Out of the Question

If protected from illegal fishing, scientists say the critically endangered species has enough genetic diversity to recover

Marine biologists suspect that the dragonfish can use its tiny fins to detect vibrations and alert them of nearby predators and prey.

Rarely Seen Torpedo-Shaped Dragonfish Spotted Off California's Coast

The copper-colored fish has only been seen four times in more than three decades of deep-sea research

Some seagrasses are linked to lower levels of gastroenteritis-causing pathogens in the water. 

Seagrass Can Work as a Sanitation Service

Millions of cases of potentially deadly gastroenteritis are prevented each year because of the pathogen-reducing powers of the plant

Black turban snails are small marine snails that make tasty prey for crabs. Failed crab attacks leave scars on a snail’s shell. By analyzing the rate of scarring and the size of the snail when it was attacked, researchers can learn important details about crab populations.

Scars on Snails Offer a 100,000-Year Record of Crab Populations

A surprisingly simple technique for studying marks on shells shows how California’s crab population has changed over millennia

A snorkeler comes face to face with a humpback whale. If humans work to halt climate change, that may help prevent another mass extinction event in the oceans.

Without Action on Climate, Another Mass Extinction Event Will Likely Happen in the World's Oceans

Marine species at the poles will face increasing pressure if warming isn’t curbed

Mapping out where these RNA viruses are found globally can help scientists understand how they interact with organisms driving the planet's ecological processes.

Virologists Identify More Than 5,000 New Viruses in the Ocean

The new study focused on under-researched RNA viruses, which often infect animals and humans

This mural outside of an outfitter's office illustrates the snaking mouth of Mosquito Bay.

Puerto Rico's Bioluminescent Bays Are Brighter Than Ever

The nightly light shows have rebounded from Hurricane Maria's devastating blow

It’s shocking how many everyday inventions we use without acknowledging the inventors that helped bring them to us.

Five Women Inventors You Didn't Learn About in History Class

These innovators pioneered word processing, launched Americans into space and more

When corals are stressed, they will expel their algal partner in a process called coral bleaching.

Mass Coral Bleaching Hits Australia's Great Barrier Reef

Unusually warm waters are stressing sensitive corals, causing the fourth major bleaching event in the last seven years

Eileen McSaveney (left) and Terry Tickhill (right) use a hand augur to drill Lake Vanda, Wright Valley, Antarctica, during the 1969-1970 field season. Water collected during this effort was used to date the lake.
