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.
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.
Sediment cores · Carbon stocks · Coastal ecology
02
Low-carbon aquaculture
We combine life-cycle assessment with greenhouse gas research to identify emission sources and evaluate management options across aquaculture systems.
Life-cycle assessment · Field monitoring · Carbon budgets
03
Bivalve–algae interactions
We study how bivalves and microalgae influence carbon exchange and water quality, linking controlled experiments with integrated aquaculture.
Co-culture · Water quality · Experimental ecology
04
Physiology & environmental stress
Our work examines how temperature, salinity, acidification and metal exposure affect marine organisms, alongside research on hybrid performance and resilience.
A closer look at recent work, from coastal sediments to experimental co-culture and farming-cycle emissions.
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.
A synthesis of shrimp-pond greenhouse gas emissions examines temporal variability across farming and non-farming periods, informing the design of more complete assessments.
