Oil residues can travel over 5,000 miles on ocean debris, study finds #ocean

Oil residues can travel over 5,000 miles on ocean debris, study finds
When oily plastic and glass, as well as rubber, washed onto Florida beaches in 2020, a community group shared the mystery online, attracting scientists' attention. Working together, they linked the black residue-coated debris to a 2019 oil slick along Brazil's coastline. Using ocean current models and chemical analysis, the team explains in Environmental Science & Technology how some of the oily material managed to travel over 5,200 miles (8,500 kilometers) by clinging to debris.

A silent ocean pandemic is wiping out sea urchins worldwide
A sudden, unexplained mass die-off is decimating sea urchins around the world, including catastrophic losses in the Canary Islands. Key reef-grazing species are reaching historic lows, and their ability to reproduce has nearly halted in some regions. Scientists suspect a pathogen but haven’t yet confirmed the culprit. The fate of these reefs may hinge on solving this unfolding pandemic.

Calm seas can drive coral bleaching, research reveals
New research by Monash University and the ARC Center of Excellence for the Weather of the 21st Century analyzed close to three decades of weather data during the coral bleaching season and identified the prevalence of "doldrum days," and the absence of the trade winds, as a key factor in the mass bleaching events threatening the Great Barrier Reef.

Norway's Deep Sea Mining Ban Strengthens Global Movement for Ocean Protection | Happy Eco News
Norway's deep sea mining ban will protect Arctic waters until 2029 after environmental pressure and green party negotiations. The decision ends public funding for mineral mapping and strengthens global resistance to ocean floor extraction. Over 40 countries now support pausing deep sea mining while recycling alternatives could provide needed minerals without environmental destruction.
