Egg cases of sharks and rays can be found washed up on the shore. Citizen science data helps scientists understand the life cycles of these marine animals and how to best conserve them.
Artificial reef stars have been added to damaged coral reefs in Sulawesi, Indonesia. A new study shows that within just four years, restored reefs are thriving as much as healthy reefs.
The toll on wildlife from illegal fishing, bycatch and entanglement in fishing gear is likely underestimated, because it doesn’t account for ‘dark’ fishing vessels, a new study finds.
The ‘20°C effect’ could give us new insights into how temperature controls ecosystems and influences evolution – as well as how species might adapt to climate change.
Photogrammetry, a technique where 3D information is extracted from photographs, is reducing the guesswork in counting – and understanding – the world below the ocean surface.
A new initiative is pinpointing areas in the world’s oceans that are key habitats for sharks and their relatives, so that governments can consider protecting these areas.
South of Cape Cod, fiddler crabs and marsh grass have long had a mutually beneficial relationship. It’s a different story in the North, where the harms can ricochet through ecosystems.
Scientists found PFAS hot spots in Miami’s Biscayne Bay where the chemicals are entering coastal waters and reaching the ocean. Water samples point to some specific sources.
A climate overshoot that creates warmer oceans with lower oxygen levels will reduce the suitable habitat for many marine species long after CO₂ levels have peaked and declined.
Rip currents are a leading cause of near-shore drownings, but there are effective ways to survive one. And these phenomena also play important ecological roles that are an emerging research area.

Water temperatures in the 90s off Florida in July are alarming, a NOAA coral scientist writes. Scientists in several North American countries have already spotted coral bleaching off their coasts.
