The Arctic Ocean may have crossed a dangerous tipping point. Scientists say the rapid disappearance of sea ice is triggering a hidden chemical shift that is stripping the ocean of nitrate — a nutrient essential for the tiny plankton that support Arctic life. As nitrate levels plunge, the entire foodContinue Reading

Proposed new regulations from the EPA would loosen requirements for protecting groundwater near power plants where the toxic residue from burning coal is stored. EPA Administrator Lee Zeldin calls the changes “commonsense” moves to maintain American energy dominance. By Arcelia Martin At a virtual public comment hearing hosted by theContinue Reading
Scientists have solved the mystery of the Seychelles’ vanished crocodiles using DNA from historic museum specimens. The reptiles were not a unique species after all, but an isolated population of saltwater crocodiles that likely drifted thousands of kilometers across the Indian Ocean., Read MoreContinue Reading
We are what we eat. And in the ocean, most life-forms source their food from phytoplankton. These microscopic, plant-like algae are the primary food source for krill, sea snails, some small fish, and jellyfish, which in turn feed larger marine animals that are prey for the ocean’s top predators, includingContinue Reading
