Overview

I am an environmental scientist working at the nexus of palaeo- and contemporary ecology. My primary research interests lie in the application of biological and geochemical techniques to address key research questions around past, present and future environmental and climate change. I have a particular interest in the peat-forming systems and palaeoclimatology of the Southern Hemisphere and I am currently working on records from the Antarctic Peninsula, New Zealand and Southern Patagonia.

Most recently, my research has focussed on the provision of longer-term (decadal to centennial) context for contemporary environmental and ecosystem changes, often driven by ongoing climatic change, which cannot be provided by instrumental or historical data alone. I also have a particular interest in the potential of cross-discipline research to provide novel, holistic approaches to future-facing Earth science research questions.

I am also an experienced field scientist having coordinated complex and remote field seasons in New Zealand, Patagonia and Alaska.

Research projects

'Holocene evolution of the Southern Annular Mode using novel peat isotope proxies'

With Dan Charman and Matt Amesbury at the University of Exeter. Funded by the Leverhulme Trust.

This project aims to reconstruct long-term variability in the Southern Annular Mode, a key component of the Southern Hemisphere's climate system. Using peatland records from across New Zealand, we'll employ a range of palaeoenvironmental techniques, including a novel stable isotopic approach recently developed here at Exeter, to look for links between changes in climate in the Southern Hemisphere and the tropics, as well as inter-hemispheric teleconnections.

‘Terrestrial Holocene climate variability on the Antarctic Peninsula’

With Dan Charman and Matt Amesbury at the University of Exeter. Funded by the NERC Antarctic Funding Initiative.

Together with colleagues from the British Antarctic Survey and the University of Cambridge, we aim to provide a longer term context for the rapid environmental changes recently witnessed on the Antarctic Peninsula. This involves the analysis of moss bank records using a multi-proxy palaeoecological and geochemical approach (testate amoebae, stable isotopes), supported by radiocarbon, lead-210 and tephra derived chronologies.

‘Palaeoclimate reconstructions from Tierra del Fuego to detect land-ocean-atmosphere interactions’

With Paul Hughes at University of Southampton. Funded by NERC.

Working with colleagues from the Universities of Aberdeen, Swansea and Plymouth, the PATAGON project aims to develop a new regional network of proxy archives and create quantitative climate reconstructions for southern South America spanning the last ~2000 years, based on the multi-proxy palaeoecological (plant macrofossils, testate amoebae) and geochemical analysis of the Sphagnum-dominated peat deposits of southern Patagonia.

Towards a Holarctic synthesis of peatland testate amoeba ecology: Development of a new continental-scale palaeohydrological transfer function for North America and comparison to European data. Quaternary Science Reviews, 201, 483-500.

Fossil testate amoeba assemblages have been used to reconstruct peatland palaeohydrology for more than two decades. While transfer function training sets are typically of local-to regional-scale in extent, combining those data to cover broad ecohydrological gradients, from the regional-to continental- and hemispheric-scales, is useful to assess if ecological optima of species vary geographically and therefore may have also varied over time. Continental-scale transfer functions can also maximise modern analogue quality without losing reconstructive skill, providing the opportunity to contextualise understanding of purely statistical outputs with greater insight into the biogeography of organisms. Here, we compiled, at moderate taxonomic resolution, a dataset of nearly 2000 modern surface peatland testate amoeba samples from 137 peatlands throughout North America. We developed transfer functions using four model types, tested them statistically and applied them to independent palaeoenvironmental data. By subdividing the dataset into eco-regions, we examined biogeographical patterns of hydrological optima and species distribution across North America. We combined our new dataset with data from Europe to create a combined transfer function. The performance of our North-American transfer function was equivalent to published models and reconstructions were comparable to those developed using regional training sets. The new model can therefore be used as an effective tool to reconstruct peatland palaeohydrology throughout the North American continent. Some eco-regions exhibited lower taxonomic diversity and some key indicator taxa had restricted ranges. However, these patterns occurred against a background of general cosmopolitanism, at the moderate taxonomic resolution used. Likely biogeographical patterns at higher taxonomic resolution therefore do not affect transfer function performance. Output from the combined North American and European model suggested that any geographical limit of scale beyond which further compilation of peatland testate amoeba data would not be valid has not yet been reached, therefore advocating the potential for a Holarctic synthesis of peatland testate amoeba data. Extending data synthesis to the tropics and the Southern Hemisphere would be more challenging due to higher regional endemism in those areas.

Variations in the isotopic composition of precipitation are determined by fractionation processes which occur during temperature- and humidity-dependent phase changes associated with evaporation and condensation. Oxygen stable isotope ratios have therefore been frequently used as a source of palaeoclimate data from a variety of proxy archives, which integrate this signal over time. Applications from ombrotrophic peatlands, where the source water used in cellulose synthesis is derived solely from precipitation, have been mostly limited to Northern Hemisphere Sphagnum-dominated bogs, with few in the Southern Hemisphere or in peatlands dominated by vascular plants. New Zealand (NZ) provides an ideal location to undertake empirical research into oxygen isotope fractionation in vascular peatlands because single taxon analysis can be easily carried out, in particular using the preserved root matrix of the restionaceous wire rush (Empodisma spp.) that forms deep Holocene peat deposits throughout the country. Furthermore, large gradients are observed in the mean isotopic composition of precipitation across NZ, caused primarily by the relative influence of different climate modes. Here, we test whether δ18O of Empodisma α-cellulose from ombrotrophic restiad peatlands in NZ can provide a methodology for developing palaeoclimate records of past precipitation δ18O. Surface plant, water and precipitation samples were taken over spatial (six sites spanning >10° latitude) and temporal (monthly measurements over one year) gradients. A link between the isotopic composition of root-associated water, the most likely source water for plant growth, and precipitation in both datasets was found. Back-trajectory modelling of precipitation moisture source for rain days prior to sampling showed clear seasonality in the temporal data that was reflected in root-associated water. The link between source water and plant cellulose was less clear, although mechanistic modelling predicted mean cellulose values within published error margins for both datasets. Improved physiological understanding and modelling of δ18O in restiad peatlands should enable use of this approach as a new source of palaeoclimate data to reconstruct changes in past atmospheric circulation.

Investigating late Holocene variations in hydroclimate and the stable isotope composition of precipitation using southern South American peatlands: an hypothesis. Climate of the Past, 8(5), 1457-1471.

Ombrotrophic raised peatlands provide an ideal archive for integrating late Holocene records of variations in hydroclimate and the estimated stable isotope composition of precipitation with recent instrumental measurements. Modern measurements of mean monthly surface air temperature, precipitation, and δD and δ18O-values in precipitation from the late twentieth and early twenty-first centuries provide a short but invaluable record with which to investigate modern relationships between these variables, thereby enabling improved interpretation of the peatland palaeodata. Stable isotope data from two stations in the Global Network for Isotopes in Precipitation (GNIP) from southern South America (Punta Arenas, Chile and Ushuaia, Argentina) were analysed for the period 1982 to 2008 and compared with longer-term meteorological data from the same locations (1890 to present and 1931 to present, respectively). δD and δ18O-values in precipitation have exhibited quite different trends in response to local surface air temperature and precipitation amount. At Punta Arenas, there has been a marked increase in the seasonal difference between summer and winter δ18O-values. A decline in the deuterium excess of summer precipitation at this station was associated with a general increase in relative humidity at 1000 mb over the surface of the Southeast Pacific Ocean, believed to be the major vapour source for the local precipitation. At Ushuaia, a fall in δ18O-values was associated with an increase in the mean annual amount of precipitation. Both records are consistent with a southward retraction and increase in zonal wind speed of the austral westerly wind belt. These regional differences, observed in response to a known driver, should be detectable in peatland sites close to the GNIP stations. Currently, insufficient data with suitable temporal resolution are available to test for these regional differences over the last 3000 yr. Existing peatland palaeoclimate data from two sites near Ushuaia, however, provide evidence for changes in the late Holocene that are consistent with the pattern observed in modern observations. © Author(s) 2012.
