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?

 

A new study found that cultivating seaweed species alongside marine finfish in integrated multi-trophic aquaculture (IMTA) operations, where seaweeds receive nutrient-rich effluent from fish production, can significantly reduce—and even eliminate—key waste products from marine finfish farming.

A new study published in the journal npj Climate and Atmospheric Science, shows that electronically tagged sharks can serve as mobile sensors, collecting ocean climate data in regions that are difficult to observe using conventional methods.
