Dr Will Hobbs is a Physical Oceanographer and Sea ice Project Co-Lead for the Australian Antarctic Program Partnership (AAPP). His primary work is on ocean-sea ice interactions, with a particular focus on Antarctic sea ice's connection to the global climate.

Biography

Will gained his PhD in 2009 from the University of California, Los Angeles (UCLA), where he studied the role of the atmosphere in driving large-scale variability of Southern Ocean sea ice. Following his PhD, Will was a post-doctoral researcher in the Ocean Circulation group at the NASA/Caltech Jet Propulsion Laboratory. His work at JPL involved combing satellite data with Argo float data to estimate the strength and heat transport of the Atlantic Meridional Overturning Circulation (AMOC). This ground-breaking time series is regularly updated and is widely used in the AMOC community.He came to Hobart in 2012 to take up a position in Ocean Detection and Attribution with the Institute for Marine and Antarctic Studies (IMAS), before moving to ACE CRC in March 2015.

Expertise

  • Climate analysis of satellite retrievals, in situ observations, hydrographic data, reanalysis data and climate model output.
  • Model-observation intercomparison
  • Climate change detection and attribution
  • Circulation of the atmosphere and ocean in the Southern Hemisphere high latitudes
  • Management and analysis of large ensemble climate model experiments

Research Themes

Will's work is aligned to the UTas research themes of Antarctic and Maritime and Environment. The Southern Ocean may seem very far away, but the ocean circulation around Antarctica is responsible for absorbing about 30% of the CO2 emitted into the atmosphere by humans, and about 75% of heat trapped on the planet by that CO2. There is a trade off for this invaluable service – namely sea level rise and ocean acidification – but without this service climate change would be an even bigger problem. Understanding how the Southern Ocean 'works' and is changing now is essential to understanding how much the climate will change in the future. Will's work is driven by the need to know how much heat the ocean can absorb, and how much it will absorb in the future.Sea ice is an essential part of the heat uptake. Each year an area of the Southern Ocean 2-3 times the size of Australia freezes over, and then melts away 4-6 months later. This staggering seasonal cycle – the largest on our planet – is partly responsible for the deep vertical ocean convection that moves heat and carbon into the deep ocean, where it can remain for many centuries.

Collaboration

Will has ongoing collaborations with scientists at the UK Met Office, working on global energy balance in coupled climate models. He also works extensively with colleagues in the US at UCLA, UC Boulder, NASA and Caltech JPL in the fields of Southern Ocean sea ice change, and ocean heat content.

Building Australia's next-generation ocean-sea ice model (2021 - 2024)$1,161,512
Description
Ocean and sea ice models are used for predicting future ocean and climate states, and for climate processresearch. This project aims to bring the next generation of ocean and sea ice models to Australia and configurethe models for our local priorities, with the ultimate goal of creating a new ocean-sea ice model for Australia thatwill include coupled surface waves and biogeochemistry. The models will be optimised and evaluated onAustralian facilities, and will be released to the community under an open-source license. These developmentsunderpin future operational needs, including ocean state forecasting, sea ice forecasts, wave forecasts, decadalclimate prediction, future climate projections and climate process studies.

Understanding spread in sea level rise projections (2016 - 2018)$290,000
Description
Sea level rise projections for this 21st century largely disagree in magnitude and spatial changes between climatemodels, particularly in hotspots. This project aims to investigate changes in water properties and ocean circulationmechanisms leading to intermodel spread in sea level projections. The expected outcomes will contribute towardsmore rigorous constraints on the likelihood of future warming and sea level rise projections, and are aligned withscientific deliverables required to address key questions in support of Australias climate change policy. They arealso aligned with international scientific deliverables in support of the World Climate Research Programme GrandChallenge on Regional Sea Level Change and Coastal Impacts.

Ocean forced evolution of the Antarctic Ice Sheet (2015)$50,365
Description
Preparing for the impacts of sea level rise needs an improved understand of the response of the Antarctic Ice Sheet to changing ocean conditions. Over the last decade it has become clear that more ocean driven melting beneath ice shelves is causing the Antarctic Ice Sheet to lose ice at an increasing rate, contributing to sea-level rise. This project will explain the role of the ocean in controlling this dynamic behavior of the Antarctic Ice Sheet. We will use state-of-the-art numerical modelling and available observations to determine the key processes that govern how the Antarctic ice flows into the oceans, together with the assessment of possible future change. This proposal will provide improved understanding of the processes controlling ice sheet and sea level and will help to provide realistic estimates of freshwater and heat transport in a global ocean context.

Research Supervision

Will currently supervises one PhD student, Serena Schroeter, who is investigating the representation of Southern Ocean sea ice trends and variability in climate models. He has also supervised some very good undergraduate students through the ARC Centre of Excellence for the Climate System Science Summer Research Scholarship program.
