Along the coast, waves break with a familiar sound. The gentle swash of the surf on the seashore can lull us to sleep, while the pounding of storm surge warns us to seek shelter.

Yet these are but a sample of the sounds that come from the coast. Most of the acoustic energy from the surf is far too low in frequency for us to hear, traveling through the air as infrasound and through the ground as seismic waves. 

The natural phenomenon of upwelling, which occurs annually in the Gulf of Panama, failed for the first time on record in 2025. A study led by scientists from the Smithsonian Tropical Research Institute (STRI) indicates that the weakening of the trade winds was the cause of this event. This finding highlights the climate’s impact on fundamental oceanic processes and the coastal communities that depend on them

Scientists from an International Council for the Exploration of the Sea (ICES) working group have called for new research to enhance habitat protection for juvenile fish species. Experts from the ICES' Working Group on the Value of Coastal Habitats for Exploited Species (WGVHES), led by Dr Benjamin Ciotti from the University of Plymouth (UK), undertook a comprehensive review to evaluate the approaches being used to assess juvenile habitat quality. Their resulting study highlights a major gap in the evidence needed to evaluate habitat quality which is in turn leading to a mismatch between policy needs and available science, with management decisions often relying on incomplete or indirect indicators.

A landmark review traces 40 years of changes in pelagic sargassum – free-floating brown seaweed that plays a vital role in the Atlantic Ocean ecosystem. The review takes a deep dive into the changing story of sargassum – how it’s growing, what’s fueling that growth, and why we’re seeing such a dramatic increase in biomass across the North Atlantic. By examining shifts in its nutrient composition – particularly nitrogen, phosphorus and carbon – and how those elements vary over time and space, we’re beginning to understand the larger environmental forces at play.
