We are a group of marine scientists who investigate biogeochemical processes in the ocean, from the sea surface to the sediments. Starting near the ocean surface, we study the distribution of microscopic plants (phytoplankton) in space and time, and how their activity contributes to determining the rate at which CO2 enters and leaves the ocean at the air-sea interface. Most of the carbon fixed by phytoplankton returns to the atmosphere, but a fraction sinks into the deeper water where it may be converted back into CO2 by the biological communities living in the ocean’s “twilight zone”. A lot of our work focuses on quantifying the type of sinking particles, the processes that fragment or consume particles, and the depth in the ocean that the carbon penetrates to, as this determines how long it can be stored out of contact with the atmosphere and so contribute to mitigating climate change.

We are a multidisciplinary team of scientists who aim to build an understanding of seafloor ecosystems through the characterisation and quantification of spatial patterns and temporal variability in their structure and functioning. We combine expertise in taxonomy, biodiversity, benthic ecology, marine biology, geomorphology, sedimentology, hydrography, habitat mapping, image analysis, multivariate & spatial statistics, and the application of machine learning techniques. Our research is based on a combination of sea-going observational work and numerical modelling approaches, and covers all water depths, from the continental shelf and margin to abyssal plains and hadal trenches. We study a wide range of marine ecosystems, mainly, but not exclusively, in deeper waters: submarine canyons, seamounts, abyssal plains, tropical and cold-water coral reefs, seagrass beds, polymetallic nodule fields, and chemosynthetic systems (cold seeps and hydrothermal vents).
Marine Ecosystem Processes
Leader: Dr Anna Lichtschlag
The Marine Ecosystem Processes Group consists of a vibrant mix of researchers with expertise from across a variety of disciplines. We are collectively interested in understanding the consequences of organism-environment interactions, e.g. for carbon and nutrient cycling, and how these are influenced by human activities. Our research approach combines laboratory and field experiments, often involving sea-going research expeditions. It also involves theoretical and numerical approaches to help develop global ecosystem models that are used to predict the future climate on Earth. We work closely with environmental regulators and policy makers to ensure that our research provides the evidence-base for responsible management policies.
Research within the Marine Ecosystem Processes group includes:
- Phytoplankton and zooplankton ecology and physiology
- Molecular microbiology
- Nutrient cycling
- Organic matter characterisation
- Marine snow biogeochemistry
- Environmental pollution and ecotoxicology
- Environmental forensics
- Earth system science
- Ecological and biogeochemical and modelling
Leader: Dr Mike Clare
We are a multi-disciplinary team of researchers who study active physical processes at and beneath the seafloor, using cutting-edge geophysical, sonar, optical and geochemical technologies for imaging, measuring, monitoring and sampling, to understand global impacts of a dynamic seafloor environments, and to enable the sustainable use of marine resources in the future. We combine expertise in geohazards, sedimentology, high resolution seismic imaging, rock physics and geomechanics, geochemistry, petrology and economic geology and work across the world’s oceans, from the poles to the tropics, from the coast to the deepest trenches. Our aim is to spatially and temporally understand dynamic processes that shape our planet and translate world-class results of societal and economic relevance to a broad range of stakeholders.
