Key research
My research involves the geochemical study of marine biological archives (massive corals) from the Indian Ocean as recorders of environmental and climate change over the past 300 years and during the Holocene. In most cases, I have worked on western Indian Ocean coral records. This work is motivated by the need to produce reliable, long-term observations of sea surface temperature, ocean currents and the hydrological cycle over the tropical/subtropical oceans.
Major research interests:
- Geochemical proxies in coral carbonate
- Indian Ocean climate change
- Global climate teleconnections
- Human impact on coral reefs
- Coral Reefs and Climate Change

Current projects
Towards a synthesis of the resilience of corals to thermal stress across Western Australian reefs and the western Indian Ocean

Mortality from thermal stress and global climate change is one of the major threats to the future of coral reefs. Understanding the spatial variability in corals’ response to thermal stress and predicting areas of susceptibility to future impacts are required to make informed decisions on the conservation of reef ecosystems. A framework for this approach exists for coral reefs in the western Indian Ocean, which we propose to apply in a workshop to Western Australian (WA) reefs. There has been an apparent increase in thermal stress and coral bleaching on WA reefs in recent years, but the existing data have not been synthesised. The proposed workshop will bring together experts across multiple disciplines and organisations to synthesise information on coral bleaching in Western Australia and identify regions of susceptibility according to the framework established for western Indian Ocean Reefs. The outputs will be used to map future impacts to WA’s coral reefs and inform management of its marine environment.

Climate change of Australia’s NW marine environment: 200-300 year records from geochemical proxies in massive corals and its implications for Australian rainfall patterns

This study proposes to examine the spatial and temporal environmental and climatological changes affecting coral reef ecosystems across the northwestern shelf of Australia over the past 300 years. To meet this goal I will examine several biological (growth rate, density, calcification) and environmental parameters (luminescence, trace elements, stable isotopes) in massive coral skeletons of the species Porites sp. which continuously grow for up to 300 years. As an overarching objective, I aim to determine how basin-wide Indian Ocean (IO) climate phenomena affect Australian and circum IO climate, i.e. Indian Ocean Dipole Mode (IOD), Subtropical Dipole Mode (SDM), by combining my previous and ongoing research on corals from the western Indian Ocean with those newly obtained off Australia from the eastern Indian Ocean.

CLIMATCH - Climatic and anthropogenic change in seasonal river runoff and impacting cyclones resolved by novel spectral geochemistry of giant corals in Indian Ocean catchments (Dutch NWO-ALW project)

Changing river runoff into marine catchments is recorded by giant corals that incorporate soil-derived humic acids in their carbonate skeleton. We developed novel, rapid techniques of spectral geochemistry to fingerprint skeletal growth banding in cores taken from giant, centuries old Porites with unprecedented, weekly resolution. As a primary objective, CLIMATCH will determine the climatic baselevel changes in runoff due to multi-decadal climate variability and extreme erosion events along the path of cyclones over the past 350 years and for Holocene time slices. As a second objective, CLIMATCH will assess anthropogenic impacts on river runoff in Indian Ocean catchments as offsets from these climatic baselevels in hotspots of land degradation, i.e. Mauritius, iconic Madagascar and Mozambique.

Coral reefs and global change – a historical perspective spanning the western Indian Ocean (Western Indian Ocean Marine Science Association (WIOMSA) – MASMA grant)

This study proposes to examine the spatial and temporal environmental changes affecting coral reef ecosystems in the Western Indian Ocean. In this multi-disciplinary project, environmental geochemists dealing with the direct data acquisition on biological archives (corals), will work in partnership with climate scientists, environmental modellers and ecologists. This will allow direct comparison of the geochemical data obtained by the geochemist with models of river discharge and pollution and ecological changes. Integration of these data should provide a far better understanding of the entire ecosystem in the region investigated and lead to improved sustainable management of the coastal environment.

Evaluating current responses and projecting the effects of climate change on WIO coral reef ecosystems from historical environmental variability (Western Indian Ocean Marine Science Association (WIOMSA) – MASMA grant)

Projecting and predicting the future effects of climate change is the first step in preparing a response that can evaluate the potential impacts on coral reef social-ecological systems. The opportunity to improve future projections is based on the accumulating information contained in coral cores and satellite data that have been collected during the past decade, which can form a basis for determining the temporal and spatial variability and how this is likely to change in the coming years. These data can, in principle, be priors in Bayesian predictive models that can be used to make predictions on future states of the environment. Additionally, the ability to predict current temperature stresses and bleaching has improved such that the probabilities of bleaching can be predicted for certain places at periods of 2 to 3 months before the impact. The proposed work will use these sources of information to develop a map of the projected changes in environmental conditions and to undertake field research in areas prior to and after the temperature anomalies to determine the impacts of current stresses on key metrics of the coral reef ecosystem including coral health, symbionts, reproduction, recruitment, and fish populations. These two studies, when combined, can be used to parameterize an existing coral reef ecosystem model to generate projections of regional ecosystem responses to future climate change scenarios.
