Study Director:


Julienne Stroeve - (Chair)
National Snow and Ice Data Center

Dr. Julienne Stroeve is a Senior Research Scientist at the National Snow and Ice Data Center (NSIDC) within the Cooperative Institute for Research in Environmental Sciences (CIRES). She received a Ph.D. in geography from the University of Colorado, Boulder for her work in understanding Greenland climate variability. Subsequently her Arctic research interests have focused on the sea ice cover and include sea ice predictability, climate change and associated local and large-scale impacts. She has conducted several Arctic field campaigns. Julienne?s work has been featured in numerous magazines, news reports, radio shows, and TV documentaries. She has given keynote addresses around the world on Arctic climate issues and briefed former Vice President Al Gore. Julienne has published more than fifty articles in peer-reviewed journals and contributed to several national and international reports on Arctic climate change.


Marika Holland
National Center for Atmospheric Research

Dr. Marika Holland is a Senior Scientist in the Climate and Global Dynamics Laboratory at the National Center for Atmospheric Research. Her research interests are focused on the role of sea ice in the climate system, including secular sea ice change, sea ice predictability, and polar climate variability. Dr. Holland has extensive experience using coupled climate models to study polar climate variability and change, and has been active in the development of improved sea ice models for climate simulations. She has served as co-chair for the Polar Climate Working Group of the Community Earth System Model, and Chief Scientist for the Community Earth System Model project. She has been a contributing author on the Intergovernmental Panel on Climate Change third, fourth, and fifth assessment reports, contributed to numerous other national and international assessments on the changing Arctic climate, and is an author on over 80 peer-reviewed publications. Dr. Holland received her Ph.D. in Atmosphere and Ocean Sciences from the University of Colorado in 1997 and held a Postdoctoral fellowship at the University of Victoria in British Columbia before joining the scientific staff of NCAR in 1999.


Xiaojun Yuan
Lamont-Doherty Earth Observatory of Columbia University

Dr. Xiaojun Yuan received a bachelor?s degree in physical oceanography from Shangdon College of Oceanography, China, in 1982. After spending four years at the National Research Center for Environmental Forecast in Beijing, she came to the United States and worked with the Scripps Institution of Oceanography studying the persistence of sea surface temperature anomalies in the North Pacific and its influence on the climate variability of the Northern Hemisphere. She then enrolled in the Ph.D. program at Scripps under the supervision of Professor Talley where she investigated oceanic fronts in the North Pacific using historical conductivity-temperature-depth (CTD) measurements together with surface fluxes. Upon receiving her Ph.D. in 1994, she moved to New York and started postdoctoral studies with Dr. Martinson at Lamont-Doherty Earth Observatory of Columbia University where she then focused on Antarctic sea ice and its relationships with global climate. She was then promoted to Doherty Associate Research Scientist in 1998, to Doherty Research Scientist in 2004, and to Lamont Research Professor in 2013.


Susan Solomon
Massachusetts Institute of Technology

Dr. Susan Solomon is internationally recognized as a leader in atmospheric science, particularly for her insights in explaining the cause of the Antarctic ozone "hole". She and her colleagues have made important contributions to understanding chemistry/climate coupling, including leading research on the irreversibility of global warming linked to anthropogenic carbon dioxide emissions, and on the influence of the ozone hole on the climate of the southern hemisphere. Her current focus is on issues relating to both atmospheric chemistry and climate change. Dr. Solomon received her PhD in Chemistry from the University of California, Berkeley in 1981, and served as Senior Scientist at the Aeronomy Laboratory of the National Oceanic and Atmospheric Administration before becoming a Professor of Atmospheric Chemistry & Climate Science at MIT in 2012.


Ted Makysm
Woods Hole Oceanographic Institute

Dr. Ted Maksym is an Assistant Scientist at the Woods Hole Oceanographic Institution. His research interests include processes driving seasonal sea ice formation and decay, ice-ocean-atmosphere interactions, and distribution of sea ice thickness and its snow cover. A particular focus is the use of autonomous platforms for observing the ice cover, including the use of autonomous underwater vehicles (AUVs) to assess the state of the ice cover. He is a veteran of twelve research expeditions to the Antarctic and Arctic, including leading the British IceBell expedition which was the first to coordinate aircraft and UAV observations of ice thickness distribution in the Antarctic. He received his PhD from the University of Alaska in 2001.


David Holland
New York University

David Holland is a Professor of Mathematics in the Center for Atmosphere Ocean Science at New York University. His research interests include geophysical fluid dynamics, computational fluid dynamics, climate system dynamics, and ice-ocean interaction. He has published more than 60 peer-reviewed articles on polar environmental science, many regarding tidal influence on the melting and freezing of glaciers and ice shelves. Dr. Holland received his Ph.D. in Atmosphere-Ocean Science from McGill University in 1993.


Marilyn Raphael
University of California, Los Angeles

Marilyn Raphael is a professor and former Chair of the Department of Geography at the University of California, Los Angeles. She is also co-Chair of the SCAR expert group Antarctic Sea ice Processes and Climate (ASPeCt) and co-Lead of the WCRP?s Polar Climate Predictability Initiative (PCPI). Her research interests are in climate variability and change particularly in the high latitude Southern Hemisphere. Her research focuses on understanding the interaction between Antarctic sea-ice variability and the large-scale atmospheric circulation using both largescale observational databases and global climate models. Her current projects focus on understanding the recent trends in the west Antarctic sea ice zone with an emphasis on improving the simulation of sea ice and the atmosphere in the Southern Hemisphere. Dr. Raphael also does work on the Santa Ana Winds of California. Dr. Raphael has served on two NRC committees ? Future Outlook for Antarctic Science and Carbon Dioxide Stabilization. Dr. Raphael received her Ph.D. in Geography from The Ohio State University.
