Biogeochemistry Research Group

Mission

Research carried out by the Biogeochemistry Research Group includes the study of processes affecting the transport, fate and impact of chemical species, including contaminants, in aquatic ecosystems. These studies aim to increase, for example, our understanding of carbon and nutrient transport, bioavailability and reactivity in the aquatic environment.  Our goal is to comprehend ecosystem functional plasticity in response to anthropogenic pressure, climate change and biological activity, leading to increased knowledge on the resilience of coastal systems to environmental change. Lately, our main research effort has focused on submarine groundwater discharge (SGD) as a pollutant transport pathway linking human activities on land to marine ecosystem health.

Dr Jean Wilson, TCD, 37k jpeg

Jean Wilson is a Research Fellow funded by the Environmental Protection Agency (EPA) under the STRIVE Water Research Programme 2012 (2012-W-MS-13). Jean’s research project “CONNECT” (COmbiNed Earth ObservatioN and GEochemiCal Tracing for Groundwater Detection and Evaluation in Ireland) is being undertaken within the Biogeochemistry Research Group headed by Professor Carlos Rocha. Professor Catherine Coxon completes the research team and more details on the CONNECT project are available here. Jean’s research interests lie in environmental applications of remote sensing, GIS and spatial analysis. She graduated from Trinity College Dublin (July 2008) with a PhD in Geography specializing in digital change detection techniques for landscape monitoring in data-poor areas using New Providence Island, The Bahamas as a case-study. Prior to that Jean completed her undergraduate studies in Geography and Mathematics and postgraduate studies in Geographical Analysis (MA in Environmental Resource Management) and Remote Sensing and GIS (Postgraduate Diploma) at NUI Maynooth. More recently, Jean completed an EPA-STRIVE funded Research Fellowship (2009-2012) supervised by Professor Carlos Rocha on developing remote sensing as a tool for detection, quantification and evaluation of submarine groundwater discharge (SGD) to Irish coastal waters. Through her research she has gained considerable experience in the use of remote sensing and geochemical tracing techniques for groundwater detection and evaluation both at home and internationally.

Inges de Rio, TCD 20k jpeg

Both Liliana and Ines are funded by the NITROLINKS project - NITROgen loading into the Ria Formosa through Coastal Groundwater Discharge (CGD) - Pathways, turnover and LINKS between land and sea in the Coastal Zone. The NITROLINKS proposal was drafted with the major scientific goal of determining fluxes and turnover rates of nitrogen in permeable beds at groundwater seepage sites in the Ria Formosa. The working programme is designed to close a significant gap in our understanding of N processing in coastal ecosystems, eventually leading to the implementation of a revised view of ecosystem functioning. It focuses on the least understood of coastal ecotones: coastal sand sediments site of Coastal Groundwater Discharge (CGD). Specifically we seek to answer the questions: (1) How important are sandy permeable sediments located on the borderline between inland groundwater inputs and productive marine ecosystems as sources or sinks of nitrogen? (2) How important is the discharge of groundwater containing NO3- into the Ria Formosa and what are its main forcing agents, and finally, (3) Do coastal managers need to take into account this contrasting interface while implementing water and land-use policies in the littoral zone?

Juan is funded by the EU (FEDER), National Science & Technology Foundation (FCT) and the Portuguese Government. Project - Nitrogen reduction in marine systems: in-situ study of alternative metabolic pathways linked to Coastal Groundwater Discharge. The objectives of this proposal are to identify, quantify and parameterize key biogeochemical processes of Nitrogen inside permeable sediments under laboratory controlled conditions and correlate these processes with in-situ flux measurements in the Ria formosa lagoon, where heavily contaminated groundwater discharges into a productive coastal lagoon, while using selected representative N molecules as proxies.
