SIMIP co-chairs
Patricia DeRepentigny
Patricia is an Assistant Professor at the University of Ottawa. Her research interests broadly cover climate projections of Arctic sea ice in Earth System Models, with the goal of improving our understanding of the multiple drivers of sea ice retreat on seasonal to centennial time scales in the context of forcing uncertainty and the internal variability of the climate system. Before her appointment at uOttawa, she was a postdoctoral researcher at UCLouvain and an ASP fellow at the National Center for Atmospheric Research (NCAR).
François Massonnet
François is a F.R.S.-FNRS Research Associate at the Université catholique de Louvain (UCLouvain). His main research interests lie in the predictability and prediction of Arctic and Antarctic sea ice at sub-seasonal to decadal time scales. He takes active participation to climate-related dissemination activities in the media and frequently engages with the general public.
Martin Vancoppenolle
Martin is a sea ice scientist at LOCEAN lab, Sorbonne Université, in Paris. His research focuses on sea ice and its interactions with climate, ocean, continental ice and marine biogeochemistry. He uses models, observations and theory. He is co-leading the development of SI3 sea ice model and participates in climate model projections by the IPSL Group. Martin is editor at Journal of Geophysical Research-Oceans and lectures on sea ice in several European universities.
SIMIP Scientific Steering Group
Edward Blanchard-Wrigglesworth
EBW is a research associate professor in the Department of Atmospheric and Climate science at the University of Washington, Seattle, USA. His areas of interest are sea ice variability and predictability, climate trends, and atmosphere/ocean/coupling, including how the polar regions interact with other regions. He uses observations and models to further our understanding, and is currently co-chair of NCAR CESM’s Polar Climate Working Group.
Ed Blockley
Ed manages the Polar Climate Group of the Met Office Hadley Centre – a group with considerable experience developing and evaluating coupled climate models and a focus on understanding climate change in polar regions. Ed has experience of ocean and sea ice modelling and assessment within the framework of the Met Office’s global climate models and operational short-range and seasonal forecasting systems. Ed is also currently co-chair of the NEMO Sea Ice Working Group and co-lead of NEMO’s SI3 “Sea Ice modelling Integrated Initiative” sea ice model.
Clare Eayrs
Clare is a Postdoctoral Researcher at the Korea Polar Research Institute. Her research focuses on the interaction between ice, the ocean, and the atmosphere and how changes in the cryosphere affect the global climate. Focusing on West Antarctica, Clare is particularly interested in the Antarctic sea ice seasonal cycle, the marginal ice zone, and the interactions between sea ice and ice sheet margins.
Alexandra Jahn
Alexandra is an Associate Professor at the University of Colorado in Boulder, studying Arctic and Paleo climate processes with a focus on the role of sea ice and the ocean in the climate system. She is especially interested in improving comparisons between climate models and observations, and was a co-chair of SIMIP between 2014-2023. In 2022/23, she was an Alexander von Humboldt Fellow in Germany.
Dirk Notz
Dirk is a Professor at Universität Hamburg, Germany. His research focuses on a broad range of topics related to sea ice, including the response of sea ice to climate change, the microstructure of sea ice, internal variability of the polar sea ice cover etc. For his research, he uses and develops a broad range of methods, ranging from in situ and remote sensing observations to conceptual model and Earth System models. Dirk is a lead author on sea ice for the recent IPCC AR6 report. He is very active in the dissemination of climate-change knowledge to the general public and stakeholders.
Alek Petty
Alek is a polar climate scientist based at the University of Maryland with a background in sea ice model development (e.g. CICE) and remote sensing data analysis (e.g. NASA’s Operation IceBridge and ICESat-2 missions). His current research is focused on improving future projections of polar sea ice using sea ice freeboard and thickness observations as well as data assimilation investigations for assessing current and potential observing systems.
Lettie Roach
Lettie is an Associate Research Scientist at the Center for Climate Systems Research, Columbia University based at NASA Goddard Institute for Space Studies (GISS) in New York City. She is broadly interested in Earth’s climate system, with a focus on the polar regions. Her research aims to better understand the physics of coupled interactions between ice and climate. She typically works with climate models of varying levels of complexity, in combination with observations, aiming to improve climate projections.
Bruno Tremblay
Bruno is a Professor in McGill’s Department of Atmospheric and Oceanic Sciences. His research focuses on sea-ice dynamics, short-term to seasonal forecast and decadal projection of Arctic ice. He has received several scientific awards including the Storke Doherty Lectureship from Columbia University, the National Oceanic and Atmospheric Administration Postdoctoral Fellowship in Climate and Global Change and the Landolt Chair “Innovations for a Sustainable Future”.
