Rate My Professor Douglas Tait

Dr. Douglas Tait is a Senior Lecturer in the Faculty of Science and Engineering at Southern Cross University. He holds a Bachelor of Environmental Science (Marine Biology) from James Cook University and a PhD from Southern Cross University. His research examines the influence of groundwater inputs on coastal environments, greenhouse gas cycling in atmospheric and aquatic systems, and the development of novel food production and wastewater systems in developing countries. Dr. Tait is a member of Southern Cross University's research clusters: Reefs and Oceans, and Catchments, Coasts and Communities. Based at the Lismore campus, his work employs natural tracers such as radon to quantify submarine groundwater discharge and associated nutrient and gas fluxes in diverse coastal settings, from mangroves and estuaries to coral reefs.

Dr. Tait has authored numerous peer-reviewed publications advancing knowledge of coastal biogeochemistry. He led the 2023 study 'Submarine Groundwater Discharge Exceeds River Inputs as a Source of Nutrients to the Great Barrier Reef,' published in Environmental Science & Technology, which demonstrated that invisible groundwater seepage delivers more nutrients than rivers, informing reef management strategies. Other significant works include 'Mangrove porewater exchange across a latitudinal gradient' (Geophysical Research Letters, 2016), 'Are mangroves drivers or buffers of coastal acidification?' (Journal of Geophysical Research: Biogeosciences, 2016), 'High porewater exchange in a mangrove-dominated estuary revealed from short-lived radium isotopes' (Journal of Hydrology, 2017), and 'Enrichment of Radon and Carbon Dioxide in the Open Atmosphere of an Australian Coal Seam Gas Field' (Environmental Science & Technology, 2013). With over 2,800 citations documented on ResearchGate across 89 publications, his research has substantial impact on understanding hidden coastal fluxes and greenhouse gas emissions. Dr. Tait supervises doctoral candidates on groundwater discharge modeling, nitrous oxide dynamics from rivers to reefs, and methane processes in coastal microbiomes. He has contributed to public outreach, co-authoring 'Groundwater into Great Barrier Reef' for The Conversation in 2023.
