Biodiversity Research Institute (BRI) announces the publication of the scientific paper Restoration of common loons following the North Cape Oil Spill, Rhode Island, USA, in the journal Science of the Total Environment (now available online). This loon restoration study, conducted in collaboration with the U.S. Fish and Wildlife Service over a 15-year period, resulted in the acquisition or conservation easements of nearly 607,028 ha (1.5 million acres) of Maine forests and waters to support the protection of 119 loon pairs in perpetuity.

ST. PETERSBURG, Fla. (September 12, 2019)- A new study from the University of South Florida St. Petersburg and Eckerd College estimates the waters of Tampa Bay contain four billion particles of microplastics, raising new questions about the impact of pollution on marine life in this vital ecosystem.
The fate of the world's coral reefs could depend on how well the sea creatures equip their offspring to cope with global warming.
Scientists obtained a total of 733 pathogen isolates from 171 individual wild Bottlenose dolphins in Florida and found that the overall prevalence of resistance to at least one antibiotic for the 733 isolates was 88.2 percent. Resistance was highest to erythromycin, followed by ampicillin. It is likely that these isolates from dolphins originated from a source where antibiotics are regularly used, potentially entering the marine environment through human activities or discharges from terrestrial sources.
California is home to 800 square miles of Marine Protected Areas (MPAs) that provide refuge to some of the most iconic and diverse marine species. What began as an effort to conserve and protect the state’s marine ecosystems now has the potential to offer critical reference points for measuring the future impacts of climate change on marine ecosystems. Learn how California State University researchers are working to advance marine knowledge and preserve the state's ocean resources.

Volcanoes are often feared for their destructive power, but a new study reminds us that they can foster new growth.
A recent study of how photosynthetic microbes and ocean bacteria use sulfur, a plentiful marine nutrient, finds similarities with soil ecosystems.
One of the tough realities of commercial fishing is that fishermen and seals sometimes compete for the same fish. And when they do, interactions between the animals and fishing nets can occur, leaving fishermen with ruined catches and damaged fishing gear
New research from conservation biologists at Florida State University and their collaborators suggests that while some loggerheads will suffer from the effects of a changing climate
Three new viruses--including one from a group of viruses never before shown to infect fish--have been discovered in endangered Chinook and sockeye salmon populations.
Late in the prehistoric Silurian Period, around 420 million years ago, a devastating mass extinction event wiped 23 percent of all marine animals from the face of the planet. For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth’s history. Now, researchers from Florida State University have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.
New research finds Arctic Ocean currents and storms are moving bacteria from ocean algae blooms into the atmosphere where the particles help clouds form.
There have been a phenomenal number of whale sightings in the waters off the coast of New York and New Jersey this summer, and those who take the time to look from shore might be lucky enough to spot one. Experts at the New York Aquarium recommend ten locations where people might have the best chance to see a whale from shore–including the roof of its own Ocean Wonders: Sharks!
Irvine, Calif., Aug. 28, 2019 – An international team of Earth system scientists and oceanographers has created the first high-resolution global map of surface ocean phosphate, a key mineral supporting the aquatic food chain. In doing so, the University of California
There has been a flurry of headlines this summer about a "nuclear coffin" leaking radioactive waste into the Pacific Ocean. The coffin—a bomb crater filled with radioactive soil on a tiny island in the Marshall Islands—sits under a 350-foot-wide concrete lid known as Runit Dome. It’s arguably the region’s most visible scar from Operation Crossroads, a series of U.S. nuclear weapons tests that took place off Bikini and Enewetak Atolls between 1946 and 1958.
Acanthocephala are parasitic worms that reproduce in the intestines of various animals, including fish.
July ended with the hottest recorded average temperature since people have been making daily readings. With the warming, climate change is assured. A huge chunk of Greenland has melted, Arctic seas have opened, and the diversity of life on Earth may be threatened. Now, the effects are spreading across the Hawaiian Islands, with some of the most diverse and abundant life under peril due to a massive coral bleaching event underway.
Climate change is altering the ability of the Southern Ocean off the West Antarctic Peninsula to absorb carbon dioxide, according to a Rutgers-led study, and that could magnify climate change in the long run.

"Seeing the pictures appear on the computer screen was the best day at work I've ever had," says Simen Ådnøy Ellingsen, an associate professor at the Norwegian University of Science and Technology's (NTNU) Department of Energy and Process Engineering.
New research from Woods Hole Oceanographic Institution (WHOI) published Aug. 19, 2019, in the Proceedings of the National Academy of Science provides evidence of the formation and abundance of abiotic methane—methane formed by chemical reactions that don’t involve organic matter—on Earth and shows how the gases could have a similar origin on other planets and moons, even those no longer home to liquid water. Researchers had long noticed methane released from deep-sea vents. But while the gas is plentiful in the atmosphere where it’s produced by living things, the source of methane at the seafloor was a mystery.
