Trevor John McDougall is an Australian physical oceanographer specialising in ocean mixing and the thermodynamics of seawater. He is Emeritus Scientia Professor of Ocean Physics in the School of Mathematics and Statistics at the University of New South Wales, Sydney, Australia, [1] [3] and is Past President of the International Association for the Physical Sciences of the Oceans (IAPSO) [4] of the International Union of Geodesy and Geophysics.
After attending Unley High School in Adelaide, South Australia, McDougall went to St Mark's College (University of Adelaide) and graduated from the University of Adelaide in Mechanical Engineering in 1973. [1] He obtained a Doctor of Philosophy in 1978 from the University of Cambridge [1] and a Graduate Diploma in Economics from the Australian National University in 1982. [1]
McDougall undertook his PhD studies in the Department of Applied Mathematics and Theoretical Physics and St John's College, Cambridge of the University of Cambridge where he was supervised by Professors Stewart Turner and Paul Linden. In 1978 he returned to Australia on a Queen's Fellowship in Marine Science at the Research School of Earth Sciences, Australian National University (ANU). [1] After five years at ANU he was appointed to CSIRO in Hobart as a physical oceanographer. [1] Since 2012 he has been Scientia Professor of Ocean Physics in the School of Mathematics and Statistics at the University of New South Wales, Sydney. [1]
McDougall's research in physical oceanography has provided insight to how seawater mixes under different conditions, which is important for understanding climate change. [3] The ocean and the atmosphere play roughly equal roles in transporting heat from the equatorial region to the poles, and McDougall's research is concerned with how the ocean reduces the equator-to-pole temperature differences, thus making Earth habitable.
McDougall is known for developing, together with David Jackett, an algorithm for defining neutral density surfaces. These are the surfaces along which swirling ocean eddies — that are 10–500 kilometres wide and persist for many months — mix. The rate of turbulent mixing in the ocean is a factor of ten million times stronger along "density" surfaces than in the direction across these surfaces. [3] [5] The accurate modelling of the ocean’s role in climate relies on being able to accurately define and evaluate these surfaces. [5] McDougall has also made significant contributions to incorporating the concepts of mixing and heat into ocean models. [3] [6]
He was president of the International Association for the Physical Sciences of the Oceans (IAPSO) [4] of the International Union of Geodesy and Geophysics from 2019-2023 and is past president for 2023-2027. He chaired the working group of SCOR and IAPSO that developed the international standard definitions of the thermodynamic properties of seawater, humid air, and ice (TEOS-10, Thermodynamic Equation of Seawater - 2010), which were adopted by the Intergovernmental Oceanographic Commission in 2009. [1] [7]
McDougall was elected a Fellow of the Royal Society in 2012. He is also a fellow of the Australian Academy of Science (1997), the CSIRO (2007), the Australian Meteorological and Oceanographic Society (2004), the Institute of Physics (UK) (2012), the Royal Society of New South Wales (2015), [8] the American Geophysical Union (2018), [9] and the International Union of Geodesy and Geophysics (2023). His other awards include:
Gordon McBean is a Canadian climatologist who serves as chairman of the board of trustees of the Canadian Foundation for Climate and Atmospheric Sciences. He is a professor at the University of Western Ontario and Chair for Policy in the Institute for Catastrophic Loss Reduction. Previously he was the Assistant Deputy Minister of Meteorological Service of Canada.
John Alexander Church is an expert on sea level and its changes. He was co-convening lead author for the chapter on Sea Level in the IPCC Third Assessment Report. He was also a co-convening lead author for the IPCC Fifth Assessment Report. He is a member of the Joint Scientific Committee of the WCRP. He was a project leader at CSIRO, until 2016. He is currently a professor with the University of New South Wales' Climate Change Research Centre.
Dan Peter McKenzie is a Professor of Geophysics at the University of Cambridge, and one-time head of the Bullard Laboratories of the Cambridge Department of Earth Sciences. He wrote the first paper defining the mathematical principles of plate tectonics on a sphere, and his early work on mantle convection created the modern discussion of planetary interiors.
Matthew England is an Australian physical oceanographer and climate scientist. As of 2024 he is Scientia Professor at the Centre for Marine Science & Innovation at the University of New South Wales, Sydney.
Spice, spiciness, or spicity, symbol τ, is a term in oceanography referring to variations in the temperature and salinity of seawater over space or time, whose combined effects leave the water's density unchanged. For a given spice, any change in temperature is offset by a change in salinity to maintain unchanged density. An increase in temperature decreases density, but an increase in salinity increases density. Such density-compensated thermohaline variability is ubiquitous in the upper ocean. Warmer, saltier water is more spicy while cooler, less salty water is more minty. For a density ratio of 1, all the thermohaline variability is spice, and there are no density fluctuations.
Lynne Talley is a physical oceanographer at Scripps Institution of Oceanography known for her research into the large-scale circulation of water masses in the global ocean.
The Prince Albert I Medal was established by Prince Rainier of Monaco in partnership with the International Association for the Physical Sciences of the Oceans. The medal was named for Prince Albert I and is given for significant work in the physical and chemical sciences of the oceans. The medal is awarded biannually by IAPSO at its Assemblies.

Conservative temperature is a thermodynamic property of seawater. It is derived from the potential enthalpy and is recommended under the TEOS-10 standard as a replacement for potential temperature as it more accurately represents the heat content in the ocean.
International Association for the Physical Sciences of the Oceans (IAPSO) is one of eight associations of the International Union of Geodesy and Geophysics (IUGG), constituted within the International Science Council (ISC). It was founded in 1919 as an oceanographic section of the IUGG and renamed an association in 1931. IAPSO is the primary body responsible for maintaining and improving oceanographic standards and practices. The President of IAPSO is Dr. Hans van Haren.
TEOS-10 is the international standard for the use and calculation of the thermodynamic properties of seawater, humid air and ice. It supersedes the former standard EOS-80. TEOS-10 is used by oceanographers and climate scientists to calculate and model properties of the oceans such as heat content in an internationally comparable way.
