stable isotopes

Stable Isotopes

Stable isotopes provide information on the trophic transfer, assimilation and fluxes of carbon, nitrogen and phosphorus within, and between, ecosystems. Read more on the facilities and research projects for Stable Isotopes.


process measurements

Process Measurements

We commonly use process measurements in our work. For benthic processes we have a selection of cores and chambers of various sizes that are used in field and/or laboratory incubations to measure processes such as benthic production, respiration, N-fixation, denitrification, anammox, DNRA and dissolved inorganic and organic carbon, nitrogen and phosphorus fluxes. Examples of cores and chambers.


field instruments

Field Instruments

The Centre has a range of field instruments for automated continuous high-temporal resolution measurements in the field.


manipulative experiments

Experimental Manipulations

Our manipulative experiments utilise mesocosms and/or chambers in the laboratory and the field to investigate global change impacts such as nutrient enrichment, temperature, ocean acidification, grazing pressure and hypoxia etc. on biogeochemical processes. The experiments can include use of stable isotope tracers to assess the impact of global changes on the trophic transfer, assimilation and fluxes of carbon, nitrogen and phosphorus within, and between, ecosystems.


material mass balances

Material Mass Balances and Ecosystem Modelling

We commonly use material budgets as a tool for studying the flow of carbon, nitrogen and phosphorus in coastal systems.


Comparative Studies

Comparative Studies

We commonly use comparative studies as a tool to better understand the cycling of C, N and P in coastal systems. In some studies we substitute 'space' for 'time' to better understand how a system will respond to global change. For these studies we will use systems of similar structure, but with different levels of disturbance. In other studies we are interested in how the structure of a system influences its function. These studies will use systems with different structure, but similar levels of disturbance .
