Historically high sea temperatures are damaging coral reefs around the world. Very high heat stress leads to coral bleaching, and prolonged bleaching can lead to coral colony death. But now scientists have found a simple method that can help protect the most vulnerable Caribbean corals: the installation of temporary shades, which protect against UV and irradiance damage, over particularly delicate corals. In an experiment in the Florida Keys, carried out in 2024 — the second-hottest summer on record in those waters — they found these shades minimized bleaching and even helped corals recover some of their color, indicating improved health.  

Researchers at SUTD have built a robotic platform that can be dropped from the air onto remote waters and sail autonomously using wind energy, pairing rapid aerial deployment with the potential for long duration marine monitoring.

New research has shown that a “floating scarecrow” developed by UK-based scientists and a repurposed bird-scaring kite can help save threatened seabirds from getting caught in fishing nets.

Dinos might have been beachcombers that dined on washed-up seafood, a new study has found. Marine plants have higher carbon isotope values than land plants and these reflect in the bodies of the animals that eat them. Researchers showed that carbon isotope traces in fossilized teeth and bones from coastal assemblages were consistently higher than the carbon isotope values of fossils from land-locked assemblages – a signature that could be linked to the consumption of seafood. The authors said the study highlights the connections terrestrial and marine ecosystems have and have had for millions of years.

UC Santa Cruz researchers adapted a new technique to measure chemical “alarm cues” from marine predators and forecast toxic algal blooms up to seven weeks in advance. This monitoring approach could be integrated into existing programs, providing coastal managers and shellfish growers with more than a month of extra warning time. The results contribute a new, top-down perspective on harmful algal bloom monitoring to help protect marine wildlife from fatal neurotoxin poisoning and prevent costly emergency shutdowns of California’s coastal fisheries.

Where are the great marine animals of the Mediterranean, such as the fin whale, the sperm whale or the bottlenose dolphin? How does their distribution change over the course of a few weeks? All indications suggest that these species shift between marine areas in a remarkably short time and over relatively small spatial scales. Some species, such as the striped dolphin, maintain a relatively stable presence in certain areas, while others, such as the fin whale, move and concentrate in different areas between one observation campaign to the next.

The U.S. National Science Foundation (NSF) awarded DRI’s Alison Murray, molecular microbial ecologist and biological oceanographer, $18.4 million to lead a project that will pave the way for the next generation of Antarctic research. Titled “Genome Infrastructure catalyzing next Generation Antarctic Data, Access, Tools, and Analytics” (GIGA DATA), the work will produce an extensive database of genetic information. More than 250 Antarctic species’ genomes will be sequenced (including algae and mosses, terrestrial and marine invertebrates, birds, fish and marine mammals) alongside 600 ecosystem samples representing tens of thousands of microbial and viral genomic datasets. This project will unite these new data together with existing Antarctic sequencing efforts under a new, artificial intelligence-enabled cyberinfrastructure. The resulting digital platform will serve as an open, accessible data science gateway to Antarctic life.
