Ocean Biology
Ocean Biology
Our ocean is a huge heat sink and absorbs atmospheric carbon dioxide. The ocean plays a central role in mitigating climate change. Researchers from the Marine Biological Association focus on the impact this has on ocean biology, from plankton to sharks. Our research on spatial dynamics of marine life, environmental changes and human impacts provides scientific evidence that can improve our understanding of the marine food web and environment; and help the effective management of the ocean.
Movement Ecology and Conservation of Ocean Predators – Sims Lab
Tracking the movements and behaviour of ocean predators to understand responses to changing environments and human threats
Professor David Sims
We track individual free-ranging sharks and other top predators using advanced telemetry and bio-logging techniques integrated with environmental data to develop models and simulations for understanding movement patterns, behavioural strategies and drivers of distributions. Understanding the complexities of shark movements and distributions with respect to changing environment and anthropogenic threats is crucial for improving conservation.

Continuous Plankton Recorder Survey – Johns
Long-term large-scale plankton monitoring programme tracking impacts of environmental change on ocean health.
David Johns
The CPR Survey is a global leader in assessing the impacts of environmental change on our oceans. Using a mechanical sampling device, a Continuous Plankton Recorder, monthly plankton samples have been collected across vast swathes of ocean since 1931. The Survey has operated in every ocean, covering more than 7 million nautical miles, and in 2021 was awarded a Guinness World Record for the greatest distance sampled by a monitoring programme. CPR data are freely available, driving better understanding of themes including climate change, human health, fisheries, biodiversity, invasive species and ocean acidification, and better management of the marine environment.

I have a lifelong interest in the behaviour, ecology and conservation of ocean predators. My research career began in 1991 with studies on the ecophysiology of feeding in small-spotted catsharks, completed in part at the Marine Biological Association. I embarked in 1995 on what has become a 25 year study of basking shark behavioural ecology. In 2001, shortly after joining the MBA as Research Fellow, we obtained the first long-term satellite trackings of basking sharks showing that they do not hibernate in winter, exhibit regional annual site fidelity, and cross national boundaries frequently, results which contributed to their international protection under CITES (2003) and CMS (2006) listings. Since 2001 I have studied the movement ecology of oceanic sharks and other threatened fish in relation to climate change and fishing. In 2016 I initiated the Global Shark Movement Project, a collaboration of over 150 scientists across 26 countries, aimed at tracking movements and changing habitats of pelagic sharks and quantifying the threats they face. We revealed where large spatial overlaps between sharks and longline fisheries and shipping occurred, demonstrating how threatened populations are most impacted. Awards for our research include the FSBI Medal (2007) and the Marsh Award for Marine Conservation (2019).

I am a marine biogeochemist and the co-ordinator of the Pacific Continuous Plankton Recorder (CPR) Survey. My research covers a range of topics from the marine carbonate system to ocean plastics. I have worked closely with the CPR dataset since my undergraduate project at Swansea University where I analysed changes in copepod abundance and distribution across the North Atlantic. My PhD was based at the University of East Anglia where I investigated how the activity and abundance of plankton may influence the variability of carbon dioxide flux in the North Atlantic. This work led to the development of a method for estimating Net Community Production (NCP) using volunteer ships of opportunity and oxygen optodes and piqued my interest in instrument development and sampling enhancements for the CPR. I have been involved in numerous syntheses reports and working groups, covering topics such as the operationalization of ecological indicators for European marine policy, ocean warming, and ocean acidification. I am an active member in the UK Pelagic Habitat Expert Group, the Global Ocean Acidification Observing Network (GOA-ON), Gulf Watch Alaska and The North Pacific Marine Science Organization (PICES).
