Aquatic carbon.
Living systems.

We study how aquatic organisms shape carbon cycling—and how that knowledge can support more sustainable aquaculture.

From coastal habitats to aquaculture systems.FIELDWORK IN TIANJIN, CHINA

Carbon stocks. Greenhouse gas fluxes. Life-cycle footprints.

Different measures, connected questions.

01 / RESEARCH

From organisms
to carbon budgets.

Field observations, controlled experiments and environmental assessment help us understand where carbon is stored, how it moves and when it is released.

Coastal carbon & bivalve habitats
01

Coastal carbon & bivalve habitats

We investigate sediment carbon stocks and burial in oyster reefs and other bivalve habitats, with attention to tidal position, season and sediment properties.

Low-carbon aquaculture

We combine life-cycle assessment with greenhouse gas research to identify emission sources and evaluate management options across aquaculture systems.

Bivalve–algae interactions

We study how bivalves and microalgae influence carbon exchange and water quality, linking controlled experiments with integrated aquaculture.

02 / HIGHLIGHTS

Questions in focus.

A closer look at recent work, from coastal sediments to experimental co-culture and farming-cycle emissions.

Oyster reef habitat in Tianjin
Tianjin oyster reef field study

CONFERENCE PRESENTATION · iCoMB 2026

What does an oyster reef store beneath the surface?

Our Tianjin case study examines sediment organic and inorganic carbon across tidal zones and seasons. Presented at iCoMB 2026, it connects habitat structure, sediment properties and carbon deposition.

Measured carbon stocks and burial are assessed separately from a complete net greenhouse gas balance.

MARINE ENVIRONMENTAL RESEARCH · 2024

Carbon dynamics in bivalve–microalgae co-culture

Controlled co-culture experiments examine the links between biological interactions, carbon dynamics and water quality.
