Areas of Research

Environmental Earth Science

The Department of Environmental Sciences is a leading centre for the study of earth surface processes and geomorphology in river, wetland, coast, desert and polar environments. Our academic and postgraduate student research (MRes and PhD) is concentrated in four main, interrelated areas;

  • Geomorphology and landscape evolution,
  • Quaternary environmental change,
  • Human impacts on the environment.
  • Environmental Management

We place a strong emphasis on fieldwork and laboratory work and have cross-departmental and cross-institutional research collaborations with colleagues in the fields of biology, climate science, geochronology and earth system science.

Our research also relates to key aspects of environmental management, and collaborative research and student supervision is carried out with industry in addition to domestic and international scientists.

Staff members active in this field of research include:

Environmental Earth Science research is supported by an extensive array of field and analytical facilities including:

  • state-of-the-art drill rigs, surveying gear (structure from motion and terrestrial laser scanning),
  • sediment analysis including grain sizing (Laser, X-ray, settling tube)
  • physical, chemical (particularly surface and down-borehole water quality), mineral magnetic instruments and dating facilities (Optically Stimulated Luminescence)

Environmental quality and contaminants

The Department of Environmental Sciences is a leading centre for the study of environmental quality and contaminants resulting from mining, industrial and agricultural activity. This research includes;

Increasingly, this research is leading to new technologies including:

  • carbon capture and sequestration (CCS) - toxic emissions from post-combustion capture (Professor Nelson),
  • gas quality and gas cleaning in oxy-combustion of fuels (Professor Nelson),
  • fugitive emissions of methane (Professor Gore, Dr Grant Edwards), in collaboration with the department of Earth and Planetary Sciences), and
  • produced water quality and treatment (Professor Gore, Dr Peter Davies, Dr Shuaifei Zhao).

Research in mature and developing technologies underpins decision making and risk assessments, but also the promotion of innovative and sustainable solutions. This includes beneficial use of waste materials in agriculture and biofuels (Professors Strezov, Professor Nelson), the catalytic removal of organics and CO2 from process and waste streams (Jiang), and solutions to the environmental impact of produced water spills (Professor Taylor).

The contaminants research theme is supported by a range of facilities and equipment including:

  • X-ray fluorescence spectrometry, Total Reflection XRF (TXRF) spectrometer, X-Ray Diffractometry,
  • mercury analysis
  • a mobile laboratory as part of the Environmental Quality laboratory

  • Inner Continental Shelf-Shoreface sediment exchanges
  • East Australian Current shelf upwelling and sand transport
  • East Australian longshore sand transport system
  • Headland sand bypassing processes
  • Large-scale coastal response to wave climate change and sea-level change
  • Coastal wetland responses to sea-level rise
  • Tidal inlet dynamics – forced vs unforced behaviour
  • Ocean wave measurement arrays and nearshore coastal modelling
  • Coastal engineering impacts on sand transport and estuarine inlets
  • Evolution of the eastern Australian coast over the past 2000 years
  • Fusion of geohistorical and instrumental coastal data for coastal hazard risk assessment
  • Role of extreme storms in multi-decadal coastal behaviour
  • Tasman Sea Extreme Storm Climatology over the past 1000 years
  • Subtropical Ridge and Latitudinal Climate Variability, impacts on coasts

Coastal and marine research is supported by equipment which includes boats, a jet ski, ground penetrating radar and a range of current monitoring equipment.

The Department’s areas of research are supported by specialist expertise in the cross-cutting themes of:

Spatial Information Science

Spatial information science is the science of geographic information systems (GIS) and remote-sensing for data storage, visualisation (mapping), and the provision of information to support decision making. It is concerned with the interpretation and analysis of geographical information from a variety of sources and in a range of application fields.

The Spatial Information Science team at Macquarie University are led by Dr Michael Chang and Dr Maina Mbui.

Research in Spatial Information Science

The Department of Environmental Sciences undertakes research using geospatial technologies, including remote sensing (both passive and active sensors) and geographic information systems, spatial modelling and multi-objective (conservation planning) decision support systems. Our goal is to inform the management of Australia’s environment through innovative and interdisciplinary research. Major themes of Michael and Maina’s research are:

Multispectral and Hyperspectral remote sensing for vegetation mapping

Radar remote sensing for land surface monitoring and terrain modelling

Spatial predictions of coastal and marine features

Cumulative impact and risk assessments in geographic information systems (GIS)

Cross-cultural participatory mapping

Conservation planning
