Patagonia ice sheets thicker than previously thought, study finds

Written on June 3, 2019.

UCI, South American glaciologists characterize protected region with new methods Irvine, Calif., June 3, 2019 – After conducting a comprehensive, seven-year survey of Patagonia, glaciologists from the University of California, Irvine and partner institutions in Argentina and Chile have concluded that the ice sheets in this vast region of South America are considerably more massive than expected. Through a combination of ground observations and airborne gravity and radar sounding methods,...

Ice loss in Antarctica is increasingly contributing to global sea level rise

Written on June 13, 2018.

UCI scientists are part of international team conducting 25-year assessment Irvine, Calif., June 13, 2018 – Loss of ice in Antarctica has caused global sea levels to rise by 7.6 millimeters since 1992, with 40 percent of the increase happening in just the past five years, according to a team of 84 scientists, including discipline-leading experts from the University of California, Irvine. Their assessment of conditions in Antarctica is based on combined data from 24 satellite surveys and...

UCI Earth system scientist joins international team studying Thwaites Glacier in Antarctica

Written on May 1, 2018.

Mathieu Morlighem, UCI assistant professor of Earth system science, is contributing his expertise in ice sheet numerical modeling to the newly launched International Thwaites Glacier Collaboration. The five-year, $25 million project, co-sponsored by the National Science Foundation and the U.K.’s Natural Environment Research Council, aims to provide answers to some of the most pressing inquiries about ice mass loss near the South Pole and the impact it will have on global sea level rise. “Thwaites,...

UCI Researchers Look at Compounding Effects of Ocean- and Land-based Flooding

Written on August 28, 2017.

Aug. 28, 2017 – Coastal areas are threatened by both oceanic and terrestrial flooding, and the combination of these factors is especially concerning as sea levels continue to rise. Untangling how oceans and rivers interact – their so-called compounding effects – is a challenge for scientists and engineers trying to estimate the current and future risk of flooding. UCI researchers have developed a new method to characterize this dual flood threat, finding that in a warming...

UCI and JPL find melting of Greenland’s glaciers worse than previously thought

Written on April 22, 2016.

New seafloor mapping techniques help scientists identify high-risk areas Carol Rasmussen / NASA Earth Science News Team Irvine, Calif., April 22, 2016 – Many large glaciers in Greenland are at greater risk of melting from below than previously thought, according to new maps of the seafloor around Greenland created by an international research team. Like other recent research findings, the maps highlight the critical importance of studying the seascape under Greenland’s coastal waters to...

NASA Awards ESS Professor Eric Rignot $2.6 Million to Continue Mapping Antarctic Ice Motion

Written on April 3, 2013.

Tatiana Arizaga, School of Physical Sciences Communications UC Irvine Earth system science professor Eric Rignot, along with associate project scientists Jeremie Mouginot and Bernd Scheuchl have been awarded $2.6 millionby NASA to continue mapping ice motion in Antarctica and to generate and distribute research data. “Our team is tremendously excited to be given by NASA the opportunity to continue our exploration of the Antarctic continent with satellite radar interferometry...

Measuring melting ice sheets

Written on March 26, 2009.

Global climate change – especially as it relates to glacial melting and rising ocean levels – is the subject of much debate and research. Eric Rignot, Earth system science professor, studies ice sheet melting in Antarctica and Greenland. He will talk about his work March 31 as part of the 2008-09 Discover the Physical Sciences Breakfast Lecture Series. Jennifer Fitzenberger, University Communications Global climate change – especially as it relates to glacial melting and rising...
