Pacific Ocean

The health of corals on the Great Barrier Reef is routinely being threatened by hot water temperatures. The Australian government is investigating a range of techniques to try to protect the corals and stave off warming.

Could Flushing Cold Water Over the Great Barrier Reef Save Corals?

Lack of action on climate change is forcing scientists to devise ever more elaborate ways to stave off damage

An oceanic whitetip shark swimming in the open ocean. This species was common in the 1970s but its population has since declined by 98 percent, according to a new study.

New Research

Oceanic Sharks and Rays Have Declined 70% Since 1970

Fishing fleets have indiscriminately slaughtered sharks for decades and a new study catalogues the environmental damage done

Three adult gray whales photographed via drone in 2017, 2018 and 2019 in Laguna San Ignacio off the coast of Mexico. The three shots show increasingly skinny whales, a bad sign for an animal that needs to make a 10,000-mile return trip to reach its feeding grounds.

New Research

Nearly 400 Gray Whales Have Died Off the West Coast Since 2019

Scientists say the die-off, which is entering its third year, is likely due to a scarcity of food in the animals’ cold water feeding grounds

The Schmidt Ocean Institute’s submersible SuBastian, which was responsible for several discoveries in 2020, is retrieved from the water.

The Top Ten Ocean Stories of 2020

From the discovery of a giant coral reef pinnacle to a shocking estimate of plastics on the seafloor, these were the biggest marine moments of the year

A small hike in the water temperature triggers corals to dispel the algae, causing them to bleach and turn a ghostly shade of white.

Some Corals Can Survive Through Relentless Heat Waves, Surprising Scientists

The organisms can recover during a heat wave instead of afterwards, and scientists call it a ‘game changer’ for conservation of the species

The study suggests that the island is built from sediment generated by the surrounding coral reef, such as from crushed up dead coral, weathered shells and dried-up microorganisms.

This Pacific Island Is Both Sinking and Growing

Sediment produced by surrounding coral reefs has helped Jeh Island outrace rising sea levels

A team of scientists on board a research vessel were on a year-long expedition to map the seafloor surrounding Australia when they discovered the reef about 80 miles off the coast of Cape York, Queensland.

A team of scientists mapped the underwater landscape and its bustling sea life using a robot

For "Overboard," artist Andy Yoder created more than 200 Nike Air Jordan sneakers using garbage.

Artist Fashions Nike Air Jordan 5s From Trash

Sculptor Andy Yoder’s latest exhibition is a nod to the Great Shoe Spill of 1990 and the advances in ocean science that came from it

Bar-tailed godwits spend their summers in the Arctic, where they breed and build up their energy reserves before flying south for the winter.

Bird Flies 7,500 Miles, a New Record for Longest Nonstop Bird Migration

After summering in the Arctic, a bar-tailed godwit soared across the Pacific Ocean like a “jet fighter” to winter in New Zealand

Blue whales are the world’s largest animals, and they can grow to the length of three school buses in a row.

Blue Whales Sing All Day When They Migrate and All Night When They Don’t

Their mysterious songs could be an ‘acoustic signature of migration’

Giving a whole new meaning to doing the “bare minimum”

This beluga whale was spotted off the coast of San Diego, California in late June. The sighting was the farthest south the normally polar species has ever been seen.

In a Rare Sighting, Wayward Beluga Spotted Off San Diego

The whale was seen thousands of miles south of its usual habitat, the farthest south the species has ever been seen

A North Atlantic right whale off the coast of Cape Cod in 2015

North Atlantic Right Whales Now Listed as ‘Critically Endangered’

Just about 400 of the whales survive in the wild, and they continue to die at an alarming rate

Biologists and local beachgoers who have encountered the decapitated marine mammals suggest humans may be to blame

During atomic bomb testing at Bikini Atoll, military equipment was placed onboard the USS Nevada to help assess the damage doled out by the nuclear blasts. This is one of four tanks that survived a 23-kiloton surface blast and a 20-kiloton underwater blast.

Researchers Locate Wreck of Battleship That Survived Pearl Harbor and Nuclear Bomb Tests

The USS Nevada was scuttled in 1948 after decades of service

A deep-sea starfish attached to what is called a polymetallic nodule. These nodules are being targeted by the burgeoning deep-sea mining industry for their mixture of valuable metals including manganese, cobalt, copper and nickel.

Deep-Sea Mining’s Environmental Toll Could Last Decades

A study of microbial communities at the site of a 1989 deep-sea mining test suggests the fragile ecosystem may take half a century to fully recover

A rock samples collected during a 2010 drilling expedition in the South Pacific that found microbes in the sea floor.

Microbes Living in Deep Sea Rocks Spawn More Hope for Life on Mars

Starved of resources, these hardy bacteria still eke out a living, suggesting life forms could survive in the harsh habitats on other planets
