Newcastle University

Background

Joined the School of Civil Engineering and Geosciences at Newcastle in 2005 as new Professor of Earth System Sciences as part of the Geochemistry Group. His area of teaching includes fundamentals of sedimentary organic matter, reconstruction of paleoclimate and paleoceanography based on geochemical and isotopic proxies, global biogeochemical cycles, petroleum source rock formation, and renewable energies. His research interests covers a variety of aspects addressing the role and functioning of carbon and nutrients in the atmosphere-land-ocean system as primary drivers of environmental and climate change and energy resource under modern and past greenhouse conditions. Key research themes include (1) Anoxic oceans and (2) Soils, Nutrient Cycling, and Hydrology in Continental Watersheds under current and past greenhouse climate conditions.

Industrial Experience

Good connections with petroleum industry complement and extend research on Past Anoxic Oceans. Currently, four active PhD research programs (2 at Newcastle, 2 in Bochum, Germany)  to study unconventional source rocks (oil shale) in Jordan in partnership with Shell.

Research Interests

Broad research themes include (1) Anoxic oceans and (2) Soils, Nutrient Cycling, and Hydrology in Continental Watersheds under current and past greenhouse climate conditions, with a general regional focus on the low latitudes (subtropics and tropics). With a focus on organic carbon production, cycling and burial from continental sources to marine sinks his research directly links with biogeochemical cycles, hydrology and catchment evolution, soils, organo-mineral relationships, ocean redox, (molecular) proxy development and application, and large scale controls on oil source rock formation at orbital time scales. The latter aspect directly connects to petroleum industries, with active research partnerships in unconventional petroleum. More recently he engaged in integrated research of tropical rainforests, combining hydroclimate monitoring with soil and water geochemistry to demonstrate the vulnerability of the forest and the forest-savannah boundaries to land use and climate change.

Current Work

Wagner’s work lies in understanding controls and feedback mechanisms associated with short- and long-term environmental change, and their interaction with dynamic terrestrial and marine carbon systems. To date, major achievements have been made in assessing the role and functioning of Land-Ocean Interaction as a primary driver of carbon and nutrient export and (paleo-)oceanographic change. High resolution inorganic, organic and isotopic records mainly from marine sediments are used to calibrate and develop a quantitative understanding of the rates and mechanisms that have caused climate and environmental change as a consequence of processes governing ocean redox conditions, land ocean interaction, carbon export and burial fluxes, hydrocarbon source rock formation and long-term plate tectonics. Specifically, the source-sink relationships of terrestrial carbon have been addressed in detail using a combination of marine and terrestrial evidence.

Future Research

In a larger context his research aims at contributing to an improved ecosystem-based management of the Earth‘s Surface by development of balanced (global) concepts between use and sustainability. More specific he empathizes his research efforts on "Carbon as a primary driver of (microbial) Ecosystems, Environmental Change and Energy Resource". The overall research is process-oriented and structured in four, closely interrelated principal research themes:
(1) Carbon and nutrients – from continental sources to marine sinks
(2) The microbial biosphere - life sustained in diverse environments
(3) Petroleum Systems – understanding black shale formation and optimising hydrocarbon production from novel sources
(4) Coal – realising the potential of coal as a natural resource with a global future

The integrated programme not only intends to stimulate and catalyse collaborative research at Newcastle and beyond but also points out opportunities and visions how existing expertise in coal geology and mining in the region may be refocused.

Research Roles

Principal investigator and Co-investigator in various international research acticities. Previously, Wagner he was holder of the prestigious Heisenberg-Fellowship of the German Science Foundation (DFG). This enabled him to spend extended periods of time working at three world-leading institutions: Woods Hole Oceanographic Institute (WHOI), Royal Netherlands Institute for Sea Research (NIOZ), and the University of Bremen (where he has worked as Assistant Professor since 1994). He has used the Heisenberg Fellowship to develop a network of research, training, and postgraduate student exchange between these institutions.

Since 1994, Professor Wagner has a success track in acquisition of research funding from national (DFG and ODP/IODP) to international (US-NSF) levels and co-ordinated cross-disciplinary and multi-institutional research at national, European, and international level.
