Warming seas fuel spread of harmful algal mega-blooms in the Bering Sea

Scientists have uncovered new evidence that climate change is driving toxin-producing harmful algal blooms (HABs) in the Pacific Arctic, raising concerns for marine wildlife, fisheries and the coastal communities that depend on the region’s resources. The Marine Biological Association (MBA) led research focuses on the Pacific Arctic region, which is warming faster than almost any … Read more

UK seas face major food chain disruption as plankton shift, scientists predict

Marine scientists warn that continued warming of UK waters is likely to cause major changes to plankton, the tiny drifting plants and animals that form the foundation of marine food webs and feed the fish that end up on our plates.

UK ratification of landmark Biodiversity Beyond National Jurisdiction Agreement strengthens protection for ocean biodiversity

The Marine Biological Association has welcomed the UK’s ratification of the Biodiversity Beyond National Jurisdiction (BBNJ) Agreement, a landmark international agreement designed to strengthen the protection of marine biodiversity across areas beyond national jurisdiction, which cover nearly two-thirds of the global ocean.

MBA-led study advances whale shark tagging techniques to support global conservation

International MBA-led study is helping to transform how researchers study the world’s largest known living fish species, offering practical guidance to improve whale shark tagging techniques and strengthen conservation efforts.

Decline in plankton across North East Atlantic sends warning for ocean health

New study has used more than six decades of data to show that plankton abundance is declining across vast swathes of the North East Atlantic – a region covering the Atlantic Ocean from Portugal to Norway, and the entirety of the North Sea.

MBA team launches whale shark tagging mission in Mexico

The MBA’s Sims Group team of researchers have travelled to La Paz, Baja California Sur, Mexico for a whale shark tagging expedition. The aim of the ERC-funded research expedition to the oxygen minimum zone (OMZ) in the Gulf of California (GoC) is to attach custom-made oxygen, temperature, deep-depth, and body movement-sensing tags to adult female … Read more

Bloomin’ Octopus! New film explores the science behind the octopus surge in the southwest

Filmmaker and diver David Palfrey expected a routine dive off the Cornish coast—but instead encountered something extraordinary: octopus after octopus, gathered in open water and observing him in return. These surprising encounters inspired Bloomin’ Octopus! A Tentacular Spectacular, a new short film exploring the remarkable ‘octopus bloom’ in southwest England in 2025.
