Peter Barrett was Founding Director (1972-2007) of the Antarctic Research Centre, Victoria University of Wellington, New Zealand, where he continues as Emeritus Professor of Geology. His early geological studies took him from Auckland University to Ohio State University, where he studied the Late Paleozoic Gondwana strata in the Transantarctic Mountains (1964-69). Since 1974 he has led a series of offshore drilling projects for a history of Antarctic climate and ice sheet behaviour since its inception around 34 million years ago. Recently he has become interested in the perspective that climate change on geological time scales offers on future climate change. From 1998-2004 he was New Zealand’s representative on the Antarctic Treaty System’s Committee on Environmental Protection. In 2006 Peter was inaugural recipient of the SCAR President’s Medal for Outstanding Achievement in Antarctic Science, and in 2011 was elected an Honorary Fellow of the Geological Society of London.



 Kathleen Conlan - Committee Member

Kathleen Conlan studies polar and deep-sea benthic community patterns and responses to change. Recent studies have been on the enrichment effects of deep submarine canyons in Australia, a benthic hotspot for grey whales in the Canadian Arctic and community responses to ice scour, seafloor methane venting, icebergs and sewage treatment in the Arctic and Antarctic. As a scientist at the Canadian Museum of Nature, Conlan actively popularizes science to increase an appreciation of and a desire to conserve the natural world. Conlan has represented Canada at SCAR since 1998 and was Chief Officer of the Standing Scientific Group, Life Sciences over 2008-2012.


 Vazira Martazinova - Committee Member

Professor and Head of the Department of Climate Research and Long-term Forecast, Ukrainian Hydrometeorological Institute, Kiev, Ukraine.  She received her PhD in meteorology from the Hydrometeorological Centre of the USSR, Moscow, Russia and Dr.Sci.  in Physics of Atmosphere from the Usikov Institute of Radiophysics and Electronics, Kharkiv, Ukraine.  Her studies focus on the changes of the large-scale atmospheric circulation in 20th-21st centuries and the development of physical-statistical models of the long-term forecast of weather. The basis of this model of the long-term forecast is a new "floating analogue" approach  that she proposed. For the last ten years  Prof Martazinova has been the scientific head  of National  Antarctic  Scientific  Center  of   Ukraine  in the  study of  climate change and weather over the Antarctic and meteorological studies in the  Ukrainian Antarctic station Faradey-Vernadsky. She has developed the methods of seasonal prediction of temperature and total ozone over the Antarctic. Members of her scientific team have spent several winters at the Ukraine Antarctic station. Prof. Martazinova served as the Expert of the World Meteorological Organization in field of atmospheric sciences and in field of climate research from 1994-2014.


Ronald Buss de Souza Ronald Buss de Souza - Committee Member

Ronald Souza holds a permanent position as a senior researcher at the Brazilian National Institute for Space Research (INPE), heading INPE's Southern Regional Centre for Space Research.  He received his PhD in Oceanography from the University of Southampton / National Oceanography Centre, Southampton (NOCS), UK in 2000.  His experience is concentrated in the field of Physical Oceanography, focusing on mesoscale processes. He acts mainly on the following subjects: ocean remote sensing, South Atlantic and Southern Ocean oceanography, air-sea interaction and fisheries remote sensing.  From 2007 to 2016, he was the head of the Antarctic Program of INPE.  He is the Brazilian representative for the Polar Space Task Group (PSTG) of the World Meteorological Organization (WMO) and the representative of INPE in the Brazilian national committees of GOOS (Global Ocean Observing System) and GLOSS (Global Sea Level Observing System).  He has participated in many cruises onboard research vessels in the Southwestern Atlantic, Indian and Southern oceans.  He is a funding member of the Brazilian National Science and Technology Institute of the Cryosphere and heading the Centre of Ocean-Atmosphere-Cryosphere Interactions of this institute.


 Catherine Ritz - Committee Member

Catherine Ritz, obtained a Phd in geophysics in 1992 at the University of Grenoble. She is senior Scientist (Directeur de Recherche) in the CNRS at LGGE (Laboratoire de Glaciologie et Géophysique de l'Environnement) where she was the head of the ice sheet modelling group. Her research interest concerns ice sheet modelling and she has developed 3D, thermomechanically coupled models that simulate the evolution of ice sheets under various climatic conditions. The time scales of interest ranged from century (for IPCC-like projections) up to 400 kyears (for paleostudies). This model has been applied to present ice sheets, such as Greenland and Antarctica, but also to the past ice sheets that covered part of the northern hemisphere during the glacial periods. She also participated to ice cores interpretation (dating, ice origin) and in continuation of this topic, she is involved in the selection of a very old ice drilling site by both modelling approach and associated geophysical observations.


 Sanjay Chaturvedi - Committee Member

Dr. Sanjay Chaturvedi is Professor of Political Science at the Centre for the Study of Geopolitics, Panjab University, India. He specializes in theories and practices of Geopolitics and IR, with special reference to Polar Regions and the Indian Ocean Region. He was awarded the Nehru Centenary British Fellowship to purse post-doctoral research on the political geography and geopolitics of the Polar Regions at the Scott Polar Research Institute (SPRI), University of Cambridge, England (December 1991 to January 1993), which was followed by highly coveted Leverhulme Research Grant of £55,000 (June 1993 to June 1995). While at the SPRI, University of Cambridge, he visited Antarctica, lecturing on board MS Alla Tarasova (Quark Expeditions, Canada) from 15 November-5 December 1994. Chaturvedi is the Regional Editor of The Polar Journal (Routledge) and Member, International Executive Committee (ex officio) SCAR Antarctic Humanities and Social Sciences Expert Group (Geopolitics). He was invited to deliver the Keynote on ‘Antarctic Science and Policy Advice in a Changing World’, the central theme of the SCAR Open Science Conference at University of Portland, USA, on 16 July 2012. He has recently been invited as a Keynote Speaker at the SCAR Antarctic Humanities and Social Sciences Expert Group Conference, ‘Depths and Surfaces’, to be held at University of Tasmania, Hobart, 5-7 July 2017. He is the author of The Polar Regions: A Political Geography, Chichester: John Wiley & Sons, 1996; Dawning of Antarctica: A Geopolitical Analysis, New Delhi: Segment, 1990. Chaturvedi is a Member of the Core Group of Experts on Antarctica and the Southern Ocean Affairs, constituted by the Ministry of Earth Sciences, Government of India, since its inception in 2004. He has served on the Indian delegation to the Antarctic Treaty Consultative Meetings (ATCMs). Chaturvedi has pursued policy-oriented research on the Polar Regions, especially Antarctica, since early 1980s.
