A new study finds that warming temperatures are causing Antarctic penguins to breed earlier, threatening some species with extinction by century's end.

On Wednesday, the Aquarium of the Pacific in Long Beach opened an exhibit where visitors for the first time can watch sick and injured sea turtles go through rehabilitation, including "Porkchop," who had a flipper amputated.

More than 500 green sea turtles were rescued in Corpus Christi, Texas, after nearly freezing to death. The animals were brought to a shelter and assessed if they needed medical care. The turtles will be released once the temperatures rise to the upper 50s.

Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying expectations. Powerful monsoons and ocean circulation appear to have delayed oxygen loss in this region compared to the Pacific. The discovery suggests future ocean oxygen levels may not follow a simple warming-equals-deoxygenation rule.

Sharktober is real in Hawaii — and it's down to the reproductive pattern of predatory tiger sharks, an analysis of 30 years of data reveals.

The National Oceanic and Atmospheric Administration (NOAA) has announced a major hydrographic survey of federal waters off American Samoa to map and characterize potential critical mineral deposits mo

Ten of us plus a crew of three set out around 7:30 on a recent morning on our Orca Quest from Channel Islands Harbor aboard the Tern, a 30-foot zodiac

California regulators will soon decide on a water plan for the Sacramento-San Joaquin River Delta. Environmental advocates warn that the proposal on the table will harm the ecosystem.

A fast-aging fish is giving scientists a rare, accelerated look at how kidneys grow old—and how a common drug may slow that process down. Researchers found that SGLT2 inhibitors, widely used to treat diabetes and heart disease, preserved kidney structure, blood vessels, and energy production as the fish aged, while also calming inflammation. The results help explain why these drugs protect kidneys and hearts so reliably in people, even beyond blood sugar control.

Scientists say grooves on a rock face overlooking the Adriatic Sea may have been made by sea turtles fleeing an earthquake.

Some of these ‘forever chemicals’ are toxic at very low levels. They can get into water systems and bioaccumulate in fish, ultimately posing risks to people.

NOAA has issued a final rule revising the permitting process for deep seabed mining exploration and commercial recovery under the Deep Seabed Hard Mineral Resources Act (DSHMRA), establishing a consol
