The Surfrider Foundation organized a beach cleanup in Miami Beach the day after Independence Day to address pollution. Hundreds of volunteers collected thousands of pounds of litter, aiming to protect marine ecosystems and gather data to influence waste reduction legislation.

Shark sightings near U.S. beaches have increased during the Fourth of July weekend, but experts confirm shark bites remain rare. Marine biologist Mike Heithaus advises avoiding murky water and fishing areas while highlighting that sharks typically ignore humans. Regions like Florida's New Smyrna Beach, North Carolina's Outer Banks, and Cape Cod see higher shark activity due to migration, warming waters, and prey availability.

Global leaders emphasize the ocean's critical role in climate action as scientists warn of a perilous tipping point. Warming oceans are altering marine ecosystems and increasing climate risks, including dying coral reefs, biodiversity loss, severe floods, and threats to food security.

Women leaders from coastal Kenya gathered in Mombasa to share community stories, discuss challenges, and explore locally led solutions for marine ecosystem protection and livelihood strengthening.

Data centres are being classified to bypass public hearings and environmental impact studies, according to activist Bolisetty Satyanarayana. He warned that the projects' water and power demands could harm marine ecosystems, fishermen's livelihoods, and the power grid.

Fish are a key solution to food insecurity in Africa, with millions relying on fisheries for nutrition and livelihoods. Marine ecosystems face threats from pollution, climate change, and overexploitation, prompting calls for urgent action to protect ocean health and communities.

The Trump administration's plan to dismantle a US ocean observation system has been criticized by scientists for severely degrading weather predictions and El Niño forecasts. The system, part of a global network, is critical for understanding the climate crisis and marine ecosystems, with its decommissioning expected to increase errors in ocean heating rate estimates.

The Trump administration is dismantling a $368 million deep-ocean observation system established a decade ago to monitor coastal environments, marine ecosystems, and global climate currents. The National Science Foundation will begin removing over 900 deep-sea instruments off Oregon in June.

A study reveals that giant octopuses, comparable in size to sperm whales, existed in Earth's oceans 72 million years ago. This discovery sheds light on ancient marine ecosystems and the diversity of prehistoric cephalopods.

A new AI-driven method called GOFLOW uses weather satellite images to create detailed maps of previously unobservable ocean currents, aiding in understanding climate, marine ecosystems, and carbon storage. The method leverages existing satellites, offering a cost-effective solution.

More than 15 million juvenile oysters will be released into the North Sea as part of a UK rewilding project aimed at repairing marine ecosystems and sequestering carbon. The initiative, using a unique rearing process, seeks to re-establish a large oyster bed around Orkney, triggering a 'trophic cascade' of ecological benefits.
