The University of Rhode Island will lead a new $94 million consortium to support ocean exploration, responsible resource management, improved scientific understanding of the deep sea and strengthen the nation's Blue Economy, the National Oceanic and Atmospheric Administration (NOAA) announced May 6.

Artificial intelligence (AI) could help scientists shed new light on the variety of species living on the ocean floor, according to new research led by the University of Plymouth.

When saltwater inundates coastal forests as sea levels rise, it kills salt-sensitive trees, leaving "ghost forests" of bare snags behind. A new study from North Carolina State University explores how changes in vegetation affect coastal bird species.

Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, new research finds.

Last week, the first Global Planning Meeting ended after three days of lively discussions with over 200 participants from science, academia, policy, communication and private sector organizations brainstorming on how to achieve the six key Decade outcomes by 2030: a clean ocean, a healthy and resilient ocean, a safe ocean, a sustainable and productive ocean, a predicted ocean and a transparent and accessible ocean.

A survey of plastic pollution on Australia's Cocos (Keeling) Islands has revealed the territory's beaches are littered with an estimated 414 million pieces of plastic debris.
