How fossil corals can shed light on Earth's past climate

Researchers have used radiocarbon measured in deep-sea fossil corals to shed light on carbon dioxide levels during Earth's last deglaciation. Fossil corals have the unique advantage that they can be precisely dated by radiometric uranium-series dating, giving an age scale that can be directly compared to the ice core records.

Could global warming lead to bigger, badder crocodiles?

Since they arrived on the scene nearly 85 million years ago, crocodiles and their relatives have often suffered when things got cool or sea levels fluctuated. The changing climatic conditions cause scores of species to go extinct. So with the world warming up, could this be a renaissance for crocodiles, reptiles that date back to the time of the dinosaurs?

Reef Watch

Check out another great citizen science project: Reef Watch. Reef Watch in South Australia provides free training to community volunteers to monitor temperate marine environments using non-destructive, internationally recognised techniques. Volunteers generate valuable scientific data that informs adaptive management for conservation of the marine environment.

Starfish Wasting Disease May Be Tied to Warming Waters

"I don't know what you would call it other than catastrophic," says Drew Harvell, a biologist at Cornell University, describing what is widely regarded as one of the worst marine disease events ever recorded. "It's staggering, really, the millions of stars that have died. It is not apocalyptic or extreme to say that." Read the full story in Discovery Channel News.

Scholarships are now being offered in dive medicine, marine conservation, marine biology, underwater archaeology, marine education, journalism, graphic arts, or photography. Training grants provide funding for diver and related underwater training and, for some awards, scuba equipment. Applications ...

Will Climate Change Bring an Invasion of the Octopuses—Or Halt It?

Climate change is bad news for many species. Environments are changing more rapidly than plants and animals can adapt to—or move out of—them. Octopuses, however, reproduce so quickly (and multitudinously) and have such short generation times, they are generally well primed to adapt and move. The common Sydney octopus (Octopus tetricus), for one, is expanding its range poleward as the surrounding oceans warm. But could a shift south ...
