Summer Intern Working On Mobile App

Emme Wiederhold, a rising junior undergraduate student at Washington University in St. Louis who is pursuing a degree in Computer Science with minors in Architecture and Design, will be interning at the lab this summer. Under the supervision of Valerie Casasanto, Wiederhold will be working on HoloGLOBE, a mobile application that combines different data sets to help users visualize and understand Earth from a new perspective: as a hologram. Emme is developing a HoloGLOBE module specific to the upcoming ICESat-2 mission.

“As the application is geared towards elementary school children and older, I am planning to integrate our ICESat-2 character, Pho the Photon, into the app to teach users about the mission in a fun new way,” Wiederhold says. She will also work on integrating some of ICESat-2’s elevation data into the app and she will participate in ICESat-2 outreach events.

ICESat-2 at Awesome Con

Two members of the ICESat-2 community participated in the 2018 Awesome Con, the Washington, DC version of Comic Con. The conference includes a section referred to as Future Con, which explores the area where science and science fiction meet.

ICESat-2’s science writer, Kate Ramsayer, organized a NASA panel for Future Con/Awesome Con entitled “NASA Science at Earth’s Extremes”. The panelists included Jacob Richardson, who discussed lava flows in Hawaii and Iceland, Lola Fatoyinbo, who talked about mangrove studies in Gabon, and lab member Kelly Brunt, who discussed her recent trip to the South Pole in support of validation of ICESat-2. Overall, the panel discussion and the questions that followed were very well received by the audience, which included many participants dressed as their favorite comic-book heroes.

New Face In the Lab: Isabel Nias 

Isabel Nias joined the Cryospheric Sciences Laboratory in March 2018 as a postdoctoral associate, working with Sophie Nowicki on a multidisciplinary sea level change project as part of the NASA Sea Level Change Team. Isabel comes from the University of Bristol in the United Kingdom, where she completed her PhD in glaciology. There, her research involved modeling the ice streams of the Amundsen Sea Embayment in West Antarctica, with a particular focus on grounding line dynamics. At Goddard, Isabel will be using Ice Sheet System Model to constrain the committed sea level contribution from the Greenland Ice Sheet.


 2018 Arctic Sea Ice Maximum Is Second Lowest On Record

This year's Arctic sea ice annual maximum extent has joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center and NASA.

On March 17, the Arctic sea ice cover peaked at 5.59 million square miles (14.48 million square kilometers), making it the second lowest maximum on record, at about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached on March 7, 2017.

New Member of the Lab: Thomas Overly

Thomas Overly has joined the Cryospheric Sciences Laboratory as a post-doctoral associate, working with Brooke Medley and Nathan Kurtz on a firn densification project. Overly comes from the Earth Sciences Department at Dartmouth College, where he used GPS, ground-penetrating radar, kite aerial photography, and CryoSat-2 data to examine surface elevation, snow accumulation, and surface roughness across the Greenland Ice Sheet. At Goddard, Thomas will use Operation IceBridge data to better understand radar interaction with the ice sheet surface.

2017 Arctic Sea Ice Minimum Extent Is Eighth Lowest on Record

Arctic sea ice appeared reached its yearly lowest extent on Sept. 13. Analysis of satellite data by NSIDC and NASA showed that at 1.79 million square miles, this year’s Arctic sea ice minimum extent is the eighth lowest in the consistent long-term satellite record, which began in 1978.

“The weather conditions in the Arctic have not been particularly noteworthy this summer," said Cryospheric Sciences Laboratory member Claire Parkinson. "The fact that we still ended up with low sea ice extents is because the baseline ice conditions today are worse than the baseline 38 years ago.”
