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.
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.
UK researchers, including from the Marine Biological Association and the University of Plymouth, have shown how the distributions of two phytoplankton groups known to produce natural toxins that can halt shellfish harvesting have changed in the North East Atlantic over the last six decades.Â
The Marine Biological Association (MBA) proudly marks its 142nd birthday, celebrating more than a century of world‑leading marine research, pioneering discoveries, and a growing international community dedicated to understanding and protecting our ocean.
December always brings with it one of the highlights of our calendar, the Annual General Meeting, and with it an invaluable moment to reflect on our science, our community and our impact. Despite what has been an undeniably challenging period for the wider world, the ocean and the academic sector, the MBA has continued to … Read more
Earth’s natural defences are losing strength as temperatures rise, major new report warns. The planet’s natural carbon sinks – the ocean, forests and soils – are reaching their limits, absorbing less carbon than expected and risking a major setback to global climate targets, according to a major new report launched today ahead of COP30. The … Read more
Scientists at the Marine Biological Association (MBA) were invited to step aboard the RRS Sir David Attenborough on its visit to Plymouth this week, as the state-of-the-art polar research vessel made a short stop at His Majesty’s Naval Base Devonport ahead of its next Antarctic mission. The RRS (Royal Research Ship), operated by the British … Read more
Populations of animals and plants – even those separated by thousands of miles – can fluctuate in synchrony, driven by shared environmental influences. This striking phenomenon, known as spatial synchrony, is the subject of a new synthesis study published in Ecology Letters, led by researchers at the University of Kansas and co-authored by Dr Lawrence … Read more

This prestigious accolade recognises Professor Thompson’s pioneering work in marine environmental science, particularly his world-leading research on marine litter and microplastics. Professor … Read more
Plankton may be among the smallest creatures in the ocean, but their significance is anything but small. These microscopic organisms, from tiny fish larvae to single-celled algae, hold key insights into the health of our ocean and the broader impacts of climate change. Through the Continuous Plankton Recorder (CPR) Survey, a collaboration led by the … Read more
