Latterly, this work has evolved to consider the impact of glacial solute and debris on global geochemical cycles and the biogeochemistry of subglacial lakes. My research has spanned the geochemistry of the full range of Earth surface waters, from atmospheric precipitation, soil-, stream- and ground-waters, through to estuarine and coastal waters, and has been conducted in environments spanning temperate, Alpine, high Arctic and Antarctic locales. The unifying theme to my research is how water routing and life impact on solute and pollutant transfer. SPECIFIC RESEARCH AREAS: I have three areas of specialism, namely snow and snowmelt chemistry/episodic acidification, biogeochemical processes in the cryosphere, and the impact of cryospheric solute and sediment fluxes on global biogeochemical cycles. a) Snow and snowmelt chemistry/episodic acidification of stream waters Acidic deposition is stored in seasonal snow packs and much is flushed out (or eluted) with the first snowmelt. Hence, there is a concentration of pollutants into the first snowmelt, that may give rise to elevated concentrations of pollutants in stream waters. My research pioneered the notion that there is differential elution of ions from snowcover, and documented how certain types of snowfall exacerbated the release of acids from snowpack. CV: Tranter; p8 Laboratory experiments were undertaken to confirm the mechanisms and processes deduced from field data. Episodic acidification of stream waters during hydrological events occurs throughout the Northern Hemisphere in both pristine and polluted environments, and is stimulated by snowmelt and rainfall. The US Environmental Protection Agency invited me to two Peer Review Meetings, prior to my enlistment as a formal consultant to, first, co-author a comprehensive review of the occurrence and causes of the worldwide, short-term acidification of stream waters which often follows rainstorms and snowmelt, and second, to oversee the data analysis and synthesis of data gathered by a multi-million dollar programme, ERP, the Episodes Research Project. b) Glacier biogeochemistry: microbial life throughout glaciers and ice sheets The routing of snowmelt and ice melt through glaciers is a key determinant of the morphology, dynamics and erosive properties of glaciers. Understanding of subglacial water routing largely arose from the chemical variations in glacial runoff. My research has examined the fundamental chemical weathering processes which operate in subglacial environments and has provided a theoretical basis for interpretation of the chemical signatures in glacial runoff. A new theme for glaciology is the existence of a flourishing microbial life atop, within and beneath glaciers and ice sheets. I have helped to pioneer an understanding of the likely subglacial energy sources for microbial life, and to document the chemical and stable isotopic signatures that life imparts on glacial runoff and accretion ice at the base of the Vostok Ice Core. My current fieldwork is based in the Antarctic Dry Valleys, as part of the NSF-funded Long Term Ecological Research Program, where I am examining how englacial microbial consortia maximise their capacity to extract and recycle nutrients from glacial debris. My current research also includes a large component of work on the biogeochemistry of subglacial lakes. I am a Steering Committee member of the Lake Ellsworth Consortium, which aims to be the first group to sample waters and microbial life from a subglacial lake beneath the Antarctic Ice Sheet. c) Cryospheric fluxes of solute and sediment: impact on global biogeochemical cycles The direct influence of major ion fluxes from glacier and ice sheet runoff to the oceans is likely to be small in terms of influencing atmospheric CO2 concentrations over glacialinterglacial timescales. However, my recent work focussing on the chemical properties of suspended sediment shows that there is great potential for glacial debris to fertilise the oceans. Reactive and bioavailable Fe inputs to the Southern Ocean, via runoff and ice bergs, are likely large enough to perturb the draw down of CO2 by globally significant amounts. Additionally, there is a significant flux of bioavailable P to the oceans via glacial debris, and the magnitudes derived from my recent estimates of glacial sediment fluxes to the oceans have stimulated a raft of new work. The ice sheets that covered the Northern Hemisphere during the last glacial cycles also buried globally significant quantities of organic matter, which is partially converted to CO2 and CH4 over time. My current research is also aimed at quantifying the magnitude and timing of the release of these climate amplifying gases during glacial-interglacial cycles.
