Humans have been on a quest to understand our planet through the ages. How is the planet changing? What is causing the change? What do those changes mean for us? In the late twentieth century we launched precision satellites. These satellites have provided the greatest insight into those questions ever gained... and incrementally we've been piecing together the puzzle.

Sea level rise and its trajectory for the future

Dr Christopher Watson is one of the scientists helping to inform our understanding of the earth system. He is a geodesist, an expert in a field that studies the changing size, shape and gravity field of Earth.

'The earth system is fascinating – all parts of the system are constantly in motion; mountains are still being formed, continents are being reshaped, and the oceans are transporting heat all over the globe.'

'The sheer magnitude of water exchange between the oceans, atmosphere, continents and cryosphere– ice and snow–is incredible; the response of this system to ongoing warming is particularly fascinating.'

Dr Watson's research is focussed on understanding sea levels and improving the accuracy of space geodesy techniques.

'Space geodesy involves the use of satellite data to monitor changes at the earth's surface. My focus is sea level and tracking its change over time.'

Sea level change is an issue of global significance. Dr. Watson, along with other University of Tasmania and Hobart based scientists, has used space geodetic data to produce a refined sea level record over the satellite era, which spans the last 20 years.

'We know without doubt that sea levels are rising. We're now getting a sense that sea level rise is accelerating over the satellite period. We're eagerly awaiting more data to see how this is expressed.'

The Intergovernmental Panel on Climate Change (IPCC) projections of sea level forecast a rise of between 28-98 cm by 2100, depending on greenhouse gas emissions. Greenhouse gas emissions are significant because they influence the amount of heat in the earth system.

Understanding the rate and extent of sea level rise is important for society as a whole, and specifically for policy makers.

'There will be a broad spectrum of impacts across the coastal zone. In Australia, it is estimated that around $226 billion of infrastructure lies within reach of the upper bound of sea level rise forecast by 2100. Current 'once in a lifetime' coastal flood events will occur much more often. Coastal ecosystems will need to adapt, and in some regions, populations will be displaced. I want to contribute to understanding the data we have, so we can plan ahead.'

Sea level rise estimates derived by Dr Watson and his colleagues can be compared with other observations that measure the different contributions to the overall sea level change signal.

'Understanding for example the contributions from the earth's ice sheets is really important – the collaborations available here in Hobart on this topic are really exciting.

'It is now clear that as a society on this planet, we have tweaked one of the controlling inputs into the earth system–heat. This has given the system a kick and the different components of the system are responding.

'There are many unanswered questions in this field and we need answers to best underpin mitigation and adaptation strategies'

One goal is to determine the regional impact of sea level rise. The rise won't be consistent across the globe. Some places will experience more sea level rise than others. Different coastal landforms will respond in very different ways. 

'I enjoy trying to provide the most accurate data possible to allow us to make intelligent and informed decisions. For society to respond to the challenge ahead, we need to be informed about what we're facing.'

Dr Christopher Watson is fascinated by understanding the changing Earth, and in particular, the response of sea level to a warming climate using satellite based sensors. He is a Senior Lecturer at the School of Land and Food in the Faculty of Science, Engineering and Technology.

Biography

Following the completion of his doctorate in 2005, Christopher joined the University of Tasmania to take up a role including teaching into the Surveying and Spatial Sciences programs, and research across the field of space geodesy and sea level change. In 2008, he was chosen as a Visiting Research Fellow at Newcastle University (UK) to further his research into space geodetic estimates of land motion with UK collaborators. 

The University of Tasmania is at the forefront of marine and Antarctic research, with the Institute for Marine and Antarctic Studies, CSIRO Wealth from Oceans Flagship and the Australian Antarctic Division all located in Hobart, providing the ideal environment to pursue research interests that seek to further understand the dynamic Earth.

Research Themes

Christopher's research is aligned with the University's research theme of Marine, Antarctic and Maritime. His research interests have an emphasis on global climate change and sea level studies, with a particular focus on improving the interpretation of geophysical signals such as sea level rise using space geodetic tools including GNSS, satellite altimetry and space gravity.

Christopher's research has emerged from an interest in historical sea level studies that investigate changes in relative sea level using benchmarks placed during the 19th and early 20thCenturies. Interpretation of such data requires investigation of sea-level and land-level change, leading to improved geophysical interpretation of these very different signals. More recently, a large part of Christopher's research is derived from contributions to the NASA/CNES Ocean surface Topography Science Team that oversees the Jason-series satellite altimeter missions. Here his research focuses on the ongoing validation and further understanding of the satellite altimeter climate data record. He is also working in the Antarctic domain to further understand the ice sheet contributions to sea level rise. His background in space geodetic research also sees Christopher collaborate with researchers involved with Unmanned Aerial Vehicles (UAVs), and their use across various environmental remote sensing applications.

Quantifying sea-level trends and extremes along Australia's coastal margin (2015 - 2017)$435,500
Description
Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from the coast and also suffers from regionally correlated biases. Here we propose to address these problems through re-tracking radar altimetry waveforms to derive new data in the coastal margin - enabling us to produce new inferences on sea-level change and extremes at dramatically improved spatial resolution around Australia.

Earth's response to ice unloading: a unique GPS measurement from Antarctica (2015)$252,500
Description
This proposal aims to deploy geophysical equipment within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660km). It exploits a globally unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice Shelf and which was followed by large-scale ice-mass unloading and rapid surface deformation. New broadband passive seismic and geodetic deformation measurements offer the promise of resolving a dichotomy between laboratory and millennial-scale determinations of Earth rheology through uniquely studying a time-scale midway between these extremes, whilst further strengthening Australia's emerging expertise in polar geophysics.

Outlet glacier dynamics in Princess Elizabeth Land (2015)$0
Description
The proposed research aims to initiate a program of observations of East Antarctic marine-terminating outlet glaciers, focussing over a three-year period on East Ranvik and Sorsdal Glaciers near Davis Station. We plan to determine to what extent processes known to enhance ice margin sensitivity to environmental forcing in Greenland and West Antarctica are at work at these two glaciers, which are logistically appealing due to their proximity to an Australian station.

ICECAP II (2015)$0
Description
This airborne geophysics and oceanography project explores the Antarctic ice sheet structure, bedrock and changing ice volume to answer key questions about Antarctica and current and future sea-level rise. Primarily, we will investigate one of the key drivers of rapid Antarctic Ice Sheet change: interaction between the ice shelves and the surrounding ocean. We will also investigate the stability of the interior for regions of enhanced basal force, factors leading to this enhancement, and conversely for areas particularly susceptible to rapid retreat of the ice sheet.

The project will synthesize geophysical information, astrometric and space-based observations to improve the definition of the coordinate system used on Earth. The study will undertake fundamental new science using the AuScope radio telescopes and will characterise the inconsistencies that currently exist in defining the terrestrial reference frame, leading to a resolution of known problems and hence to more accurate geophysical studies that depend upon spatial observations (e.g. sea level rise, glacial isostatic adjustment, crustal deformation). Key reference frame and climate-change related science problems will be resolved simultaneously to deliver outcomes that will inform and prepare our society for future policy and research requirements.

Geophysical, Galactic, and Extra-galactic Science with the AuScope and ASKP Arrays (2010 - 2013)$556,800
Description
This research will determine the scale of the Milky Way Galaxy and the structure of its interstellar gas. It will generate a catalogue of primary reference radio sources for the extension of the International Celestial Reference Frame to the Southern Hemisphere. The project will extend this to the earth by linking the celestial reference frame to the terrestrial reference frame. This will fulfil the mission of the AuScope array by setting the Global Positioning System on a solid foundation in Australia and other Southern Hemisphere nations to measure changes in the Earth.
