Video and audio monitoring of the Arctic seafloor captures rarely seen phenomena: fish swimming backwards, narwhal calls nearby, and a beautiful array of deep-sea dwellers and tide-driven "marine snow”

Simon Fraser University researchers have received nearly $1 million in special funding from the Digital Research Alliance of Canada to develop an artificial intelligence–powered system that forecasts whale movements in busy shipping corridors.

The Humans and Algorithms Listening for Orcas (HALLO) project aims to help the Port of Vancouver and vessel pilots make more informed decisions about when and where to slow down for the Salish Sea’s endangered Southern Resident killer whales.

The system integrates real-time acoustic and visual data, vessel tracking, and citizen-scientist whale spotting reports to track not only where the Southern Resident J, K, and L pods currently are, but forecast where they’ll be over the next few hours. 

A new study reveals how responsive the Greenland ice sheet is to climate change – more so than models predict. Methane has been detected at retreating glacier margins worldwide, but this is the first time that a study has investigated the margin of an entire ice sheet. 

A consortium led by the University of Vaasa, Finland, has been awarded significant Horizon Europe funding for a major research and innovation project that moves long‑distance shipping closer to a zero‑carbon future. The H4PERION – Hydrogen FOR Performance Enhancement and Reliable Ice OperatioN – project will, for the first time, demonstrate in practice how a large vessel can operate with a hydrogen‑capable internal combustion engine (ICE). This marks an important milestone in clean maritime technology.

For 350 million years, ammonites were the resilient masterpieces of the ancient seas. They survived the Great Dying of the Permian-Triassic, an event that wiped out 96% of marine life, only to vanish during the end-Cretaceous extinction that claimed the dinosaurs. Meanwhile, their less-diverse cousins, the nautiloids, sailed through the catastrophe and still inhabit our oceans today.

Why did the invincible ammonites fail while the nautiloids endured?
