Environmental Processes and Change

This research theme concerns itself with the processes that either drive or are affected by environmental change. The understanding of these processes leads to proxies that are used to reconstruct past environmental change over a range of spatial and temporal scales. Key research areas in this theme include Biogeochemistry, Catchment System Science Quaternary Science and Geochronology and Climate Adaptation.

In Biogeochemistry we study the biological and (geo)-chemical processes that are part of the earth system. We focus on earth system-climate interactions from Quaternary to contemporary timescales using a range of techniques including carbon and nitrogen fluxes, stable isotopes and organic geochemical lipid biomarkers.

Research in Catchment System Science (CSS) focusses on the transfer of sediments and solutes in catchments as they directly influence river morphology, water quality, habitat conditions and biogeochemical cycles. Research is undertaken using a variety of field, experimental and modelling methodologies.

Given concerns over human-induced changes to the world’s climate over the next century our research in Quaternary Science and Geochronology (QSG) seeks to understand the causes of major climatic fluctuations throughout geological history in terms of the complex interactions and feedbacks between the atmosphere, oceans and terrestrial land surfaces. Our focus is the low-latitudes since the redistribution of heat from this zone to higher latitudes is a critical driver of global climatic change.

Climate Adaptation and building resilience to extreme weather events is a research theme driven by the need for sustainable responses to current and future environmental challenges. Our research in this area focuses on understanding the climate risk, impacts, opportunities and resilience associated with sensitive environments, using a variety of field-based, geospatial and modelling approaches.
