Ocean News: Mercury Levels Rising in Surface Waters, Penguin Species Threatened by Habitat Degradation, and More
- According to a new study, mercury levels in many of the world oceans’ surface waters have tripled due to human activity. Because mercury drains into the ocean from mines, coal-fired plants, and sewage, mercury levels are higher in surface waters compared to the deep ocean. The Guardian

It appears that some marine mammals are certainly welcoming the presence of offshore wind farms.
Satellite tags on grey and harbor seals reveal that these apex predators are frequenting two offshore wind farms in the North Sea to forage for prey. According to a study recently published in Current Biology, 11 seals showed evidence of foraging at the Alpha Ventus wind farm off Germany and the Sheringham Shoal wind farm off the United Kingdom, moving in a grid-like pattern as they swam from turbine to turbine.
Earlier this month, Spain’s Ministry of Agriculture, Food, and Environment (MAGRAMA) approved a proposal to add four marine areas as Sites of Community Importance to the Natura 2000 Network—the backbone of marine protection in the European Union. These four areas—the western system of submarine canyons in the Gulf of Lions, the Channel of Menorca, the mud volcanoes of the Gulf of Cádiz, and the Bank of Galicia—stemmed from LIFE+ INDEMARES, a project Oceana is a partner on.
- Researchers recently found that the bumphead parrotfish can benefit but also harm coral reef ecosystems in the Pacific. Bumpheads help coral reefs reproduce and reduce-fast growing algae that compete with corals, but since bumpheads do eat coral, they can reduce its abundance and diversity. Red Orbit
When you’re out swimming or surfing at the beach, have you ever wondered which ocean animals surrounding you have teeth? It turns out that sharks aren’t the only marine animals with teeth—a tool in some marine animals may be more widespread than you thought.
From hundreds of sharp, razor-blade-like teeth in great white sharks to the singular long, spiraled tooth on narwhales, teeth come in all shapes in sizes in marine ecosystems. This diversity is for good reason—some use their teeth to shred and slice prey, while others use their teeth more as a harpoon.
It’s that wonderful time of year again on the East Coast: sea turtle hatching season! Turtle nests—from green sea turtles to loggerheads, Kemp’s ridleys, and even more species—are starting to hatch from Virginia to the Gulf of Mexico. If you’re a sea turtle lover and haven’t made it to the beach to catch a nest hatch, don’t worry—the Florida Keys Turtle Cam has got you covered.
