New research finds that Marine Protected Areas can boost the recovery of globally important kelp forests following marine heatwaves. The findings are published in the British Ecological Society’s Journal of Applied Ecology.
A new study, led by University of Hawai‘i at Mānoa oceanographers, revealed that the ocean is acidifying even more rapidly below the surface in the open waters of the North Pacific near Hawai‘i.
The shipping industry has long relied on fossil fuels, contributing significantly to global pollution. With stricter environmental regulations like the International Maritime Organization’s (IMO) greenhouse gas reduction strategy, the shift toward electric ships powered by lithium-ion batteries (LIBs) is now unstoppable. These battery-powered vessels promise cleaner, more efficient maritime transport—but there’s a catch: the harsh marine environment poses unique challenges for battery performance and safety.
The next time you breathe, consider this: photosynthesis of algae, powered by iron dust in the ocean, made it possible. Now, a new Rutgers University study published in the Proceedings of the National Academy of Sciences pulls back the curtain on this vital process.
Iron is a critical micronutrient for marine phytoplankton, the microscopic algae that form the foundation of the ocean’s food webs. It is deposited into the world’s oceans as dust from deserts and arid areas as well as from glacial meltwater.
