Research

Professor Stroeve's research has covered Arctic climate change, sea ice decline, atmosphere-ocean ice interactions, remote sensing, and the impact of climate change on native communities. Her recent work has focused on satellite retrievals of Arctic sea ice, and the implications of changing Arctic sea ice on Earth's climate. She has published 162 articles. Her research has shown that

Arctic sea ice decline Arctic sea ice decline has occurred in recent decades due to the effects of climate change on oceans, with declines in sea ice area, extent, and volume. Sea ice in the Arctic Ocean has been melting more in summer than it refreezes in the winter. ...

has happened much faster than models had predicted in recent decades, and that humans may have been the cause of most of this decline. She has also written about the current trend and future predictions of "darkening", or a reduction in

Awards

Professor Stroeve was awarded the EGU 2020 Julia and Johannes Weertman Medal, for her 'fundamental contributions to improved satellite observations of sea ice, better understanding of causes of sea ice variability and change, and her compelling communication to the wider public'. She is an ISI highly cited researcher, regularly listed as one of Thompson Reuters most highly cited scientists, and a Canada 150 Research Chair at the University of Manitoba.
