Over the coming weeks we will introduce members of each team working on the iGlass consortium project. Today we will introduce the team from the National Oceanography Centre in Liverpool.
Dr Mark Tamisiea
Mark Tamisiea is a geophysicist that studies the motion of the Earth’s crust and variations of water depth in the oceans caused by past and present changes of the ice sheets. This collective response of the crust ond oceans is typically called glacial isostatic adjustment (GIA). His Ph.D. in physics from the University of Colorado at Boulder examined how solid-solid phase transitions in the Earth’s mantle might affect observations of GIA. Starting with his post-doc at the University of Toronto, his work has focused on the regional sea level changes caused by GIA. Understanding the regional differences is vital to interpreting the causes of past and present sea level change. Mark has been at the National Oceanography Centre (formally the Proudman Oceanographic Laboratory) since 2007 and prior to that was at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.
Dr Svetlana Jevrejeva
Svetlana Jevrejeva is a physical oceanographer who works for NOC Liverpool since 2002. Her main research interests are in the variability of global and regional sea level change and development and application of advanced statistical methods. She had contributed to the development of the wavelet coherence method and is author of the unique sea level reconstruction since 1700. She has major publications in the field of time series analysis and the application of novel statistical methods to earth science problems. During the Fifth Assessment report of Intergovernmental Panel of Climate Change (IPCC) she was a Lead Author of the Working Group 1 chapter on Sea level changes. Recent work has focused on sea level projections by 2100, changes in extreme sea levels in the past and their link to climate change.
Dr André Düsterhus
André Düsterhus is a meteorologist specialised in statistical data analysis. He is part of iGlass since 2013 and is working on the connection between GIA modelling and observations of the sea-level variations in the past interglacials. This is done by using verification and data assimilation techniques with a focus on Bayesian statistics. Prior to his appointment at NOC Liverpool, André had received his diploma and PhD in meteorology at the University of Bonn and worked within the climate dynamics workgroup of Andreas Hense. His PhD thesis covered the development of quality assurance procedures within data publication processes. A focus was set therein on the development of statistical quality assurance tests on general data and data peer review schemes.
Over the coming weeks we will introduce members of each team working on the iGlass consortium project. Today we will introduce the Durham University team.
Professor Antony Long
Antony holds a Chair in Physical Geography at Durham University. His research interests are Quaternary environmental change, especially past and future sea-level change and coastal evolution around Greenland and the North Atlantic. He is particularly experienced in the use of isolation basins, estuarine and salt marsh sediments to reconstruct past sea level, and has, most notably, produced key relative sea-level datasets for Greenland, along with reconstructions of the former position of the ice sheet since deglaciation, constraining the ice load over a range of timescales. Alongside this he has worked around the wider North Atlantic using salt marsh sediments to reconstruct sea level over decadal to millennial timescales; on buried estuarine sediments in the Irish Sea that record late glacial sea-level changes; and Holocene sea level and coastal evolution in England and north west Scotland. Antony is Head of the Department of Geography at Durham University. He is currently a co-leader of PALSEA2, Editor in Chief of Journal of Quaternary Science, and sits on the Executive Committee of the Quaternary Research Association.
Dr Natasha Barlow
Natasha is a postdoctoral researcher on the iGlass project, having done her PhD at Durham. Her interest is reconstructing Quaternary environments, and in particular relative sea-level change on both active and passive coasts. Natasha is particularly experienced in the use of diatoms to quantitatively reconstruct relative sea-level change from coastal sediments, along with developing chronological frameworks. This has led her to apply these techniques to salt marsh sediments from around the North Atlantic that act as ‘geological tide gauges’ for the last 2000 years (her previous postdoc) and reconstructions of land-level changes associated with great earthquakes in Alaska. She also has some experience in glacial isostatic adjustment modeling and continues to work on questions regarding the impact of mass balance changes on sea level in Alaska, Iceland and South Georgia.
Last night a couple of iGlass members attended the Geological Society of London Special Lecture given by Prof. Kurt Lambeck. Prof. Lambeck was presented with the Society’s highest award, the Wollaston Medal and gave an overview of his research career that spans more than 50 years. We were treated to an overview of his work with a focus on: what we have learnt about past ice sheets from geophysical inversion models, the mantle’s response to loading on timescales of thousands of years and lessons from the past that may be relevent in understanding present (and future) sea level change.
