About the Project

Position Reference: 02STEM2020

Keywords: carbon, littoral zone, high alkalinity, humic lakes, biogeochemistry

This project aims to address the gap in the global literature on carbon fluxes in the littoral zones of both high and low alkalinity lakes.

Although lakes occupy a comparatively small area in the global landscape, they nevertheless have a disproportionally important role in global carbon cycling owing to their importance in carbon transport, processing and storage and are considered to be a significant source of carbon dioxide (CO2) to the atmosphere. These emissions are widely understood to be linked to microbial breakdown of terrestrially derived carbon (heterotrophic oxidation). However, the majority of studies that directly link CO2 supersaturation to heterotrophy are based on relatively low alkalinity lakes with high dissolved organic carbon inputs from the catchment, and amongst these studies the emphasis has been placed on the open water zone of a lake. However, the shallower waters of the littoral zone surrounding the edge of lakes have received less attention. Recent studies have also pointed to the possible role of calcite precipitation and dissolved inorganic carbon (derived from the weathering of rock in the surrounding catchment) in high alkalinity lakes as major drivers of CO2 emissions and offers a potentially alternative, although poorly studied, mechanism for CO2 fluxes in freshwater lakes. This project aims to address the gap in the global literature on carbon fluxes in the littoral zones of both high and low alkalinity lakes. This will be done though a targeted research programme to examine processes in carbon cycling in the littoral zone of both a high and low alkalinity lake in Ireland and examine mechanisms responsible for these fluxes and their interaction with nutrient dynamics and littoral zone biological communities.
