Tracing plastic from 1,000 rivers to nearly 80% of ocean emissions
A thousand rivers, represented by the red dots on our map, account for nearly 80% of global annual riverine plastic emissions, between 0.8 and 2.7 million metric tons per year. The most polluting among them are small urban rivers. The remaining 20% is spread across 30,000 others, shown in blue. Understanding drives protection; this empirical, peer-reviewed data gives us a measurable starting point for action. For deeper context, see our piece on how ocean data calibrates the energy transition, published with the World Economic Forum.
Arctic LNG 2 Seeks $1 Billion in Arbitration Against Hanwha Ocean
Arctic LNG 2 has filed a $1 billion arbitration claim against Hanwha Ocean in Singapore, a direct consequence of a terminated shipbuilding contract. This legal action underscores the high stakes of Arctic infrastructure development amid mounting geopolitical friction. The claim is a calibrated move, reflecting the measurable financial impact of disrupted supply chains.

Acadia: Pioneering Subsea Rock Installation for Coastal Resilience
The Acadia now holds the title of the first U.S.-flagged, Jones Act-compliant subsea rock installation vessel, a milestone that sharpens our domestic coastal resilience capabilities. Great Lakes Dredge & Dock Corporation's delivery of this SRIV is a measured step forward in protecting shorelines with precision. We see this as a practical expansion of ocean intelligence, not hype. For broader context on the technology's evolution, our coverage of Van Oord's Vindnes and Vestnes offers useful comparison. Understanding drives protection, and the Acadia strengthens that equation.
