Hotter oceans are putting coral reefs in peril worldwide. Scientists are warning that to save them, heat-trapping emissions must fall, and reefs will need more protection and restoration.
Climate change is hitting the oceans hard, both warming and acidifying the water. Ocean scientists are hoping the Biden Administration dives in quickly to address it.
A new study suggests there is far more plastic in the Atlantic Ocean than scientists estimated earlier, especially tiny pieces of plastic that can end up inside fish and other animals.
A drop in shipping traffic is reducing underwater noise, so scientists are listening for how whales and other marine life are responding.
Scientists have found that dolphins learn a neat trick to trap fish by watching their close associates do it. This means that dolphins aren't just motivated to learn from their mothers.
The U.N. Intergovernmental Panel on Climate Change has released its latest report on the oceans, and it's not good. The report also notes a relatively new phenomenon in the oceans: marine heat waves.
Stacy Jupiter works with the people of Fiji to protect the oceans. Two of her most important life lessons came from the Peace Corps: 1) listen and 2) nothing ever goes according to plan.
"The big picture of survival is sometimes so hard to see, but we always know what we can do to make the next best step toward survival," says cave diver, photographer and memoirist Jill Heinerth.
Scientists need to track the history of sea temperatures precisely to model climate change. A newly discovered clue in measurements taken by sailors in the 1930s could have far-reaching implications.
Sea stars along the Pacific Coast are dying in the largest disease epidemic ever documented in a wild marine species. New research suggests warmer water is making the disease even more deadly.
