AOSC student Kelsey Malloy named UMD undergraduate researcher of the year

AOSC Senior Kelsey Malloy has been named a 2017 University of Maryland Undergraduate Researcher of the Year for her work on improving forecasts of rapid cyclogenesis and hurricane force-wind events. For the past two year, Kelsey has been working with a team of researchers at the NOAA Ocean Prediction Center, led by Dr. Michael Folmer and Lt. Joseph Phillips, to use the latest data from the Himawari-8 satellite combined with analysis techniques developed for use with the GOES-16 satellite. Kelsey's work will be used be used by forecasters to improve the safety of mariners at sea.

This has been a great year for Kelsey as earlier this year, she became a Phillip Merrill Presidential Scholar. This fall, Kelsey will enroll in the University of Miami's PhD. program working on climate variability and subseasonal to seasonal predictions with Dr. Ben Kirtman.

Prof. Ross Salawitch discusses the Paris Agreement.

Flooded and in the midst of a strong Pacific storm system, the audience of KCAL was looking for some clarity as to what type of progress has been made in the fields of weather prediction and climate modeling. Professor Ross Salawitch was there to provide the answers. On February 18, Salawitch appeared on the CBS Los Angeles affiliate, KCAL-9, to discuss his new book, “Paris Climate Agreement: Beacon of Hope,” and explain prevalent misconceptions in the climate system. He explained the different reduction targets countries had set in the agreement, highlighting the fact that the U.S. under the agreement is currently committed to a 27 percent reduction in carbon emissions. Salawitch commended Jerry Brown and California for their efforts in reducing carbon emissions. The hosts brought up the prevalent misconception that because winters are still cold and wet in California, climate change cannot be a pertinent issue. Salawitch used this segueway to explain the fundamental difference of climate and weather, conveying to audience members that no conclusion about our current climate state could be derived from a mere observation in the weather.

Honors for AOSC Faculty and Alums

This week faculty member Tony Busalacchi is formally being inducted into the National Academy of Engineering. Tony has also, as you know, taken on Directorship of UCAR.

This month distinguished alumnus Dr. Curtis Mobley (*77) will be presented with the 2016 Oceanography Society Jerlov award for his work on applying radiative transfer theory to optical oceanography and ocean color remote sensing, and his hydrolight software.

In January Professor Zhanqing Li is adding to his already crowded award collection, by being appointed as a 2017 AMS fellow, to match his Fellow appointments in the AAAS and AGU.

Glaciology Summer Camp

A local Terp will be found in the unlikeliest of places this summer, McCarthy, Alaska. Casey Cavanagh, a first year graduate student in the Department of Atmospheric and Oceanic Sciences, was selected to participate in the Glaciology Summer Camp, managed by the University of Alaska-Fairbanks and sponsored by NASA, The International Glaciological Society (IGS), The International Association of Cryospheric Sciences (IASC), and the International Union of Geodesy and Geophysics (IUGG). McCarthy is small village (with a handful of inhabitants remaining during the winter months) that is located at the base the Wrangell Mountains near the Canadian border, where large mountain glaciers terminate at the edge of the town. Out of the over 100 applicants, approximately 25 students will participate in the field camp offered every other year. The course is intended to provide glaciology graduate students with a comprehensive overview of the physics of glaciers and current research frontiers in glaciology with a focus on quantitative glaciology, modeling and remote sensing of glaciers and ice sheet dynamics. The students will also get to participate in field expedition work on the terminating glaciers. In addition, each student will present an AGU-style poster presentation on his or her present work in glaciology. Casey’s research will focus on the effects that draining saturated crevasses have on localized velocity changes of Jakobshavn Isbrae in Western Greenland.

Greenland Ice Sheet

Numerous and extensive changes have been observed over the Greenland Ice Sheet in response to regional warming. The coupling of surface melt and ice dynamics has an important impact on ice sheet mass loss to the ocean and sea-level rise. This summer, Dr. Derrick Lampkin has been involved in several efforts aimed at understanding these processes better. During the month of May, Dr. Lampkin participated in a field expedition to the Greenland Ice Sheet as part of his involvement in using Global Positioning Systems (GPS) to continuously monitor ice movement. Dr. Lampkin was involved in collecting data and maintaining an array of five GPS receivers that are permanently embedded into the ice. These embedded antennas collect data on the displacement of ice in three dimensions, particularly during the summer months when copious amounts of surface melt water infiltrate into the ice sheet and accelerate ice movement. Dr. Lampkin collaborated with Dr. Jay Zwally (ESSIC, AOSC) and Konrad Steffen (ETH) to retrieve and process the previous seasons data.

Additionally, Dr. Lampkin has been involved in the recent discovery of a new process involved in the Greenland Ice Sheet’s supraglacial hydrology. Dr. Lampkin co-authored a work published in the Journal Cryosphere, ‘Wintertime storage of water in buried supraglacial lakes across the Greenland Ice Sheet’, detailing the discovery of water buried and persisting throughout the winter months in frozen-over supraglacial lake basins. “It was surprising for us to find water sticking around in these basins through the winter. This single phenomena could be an important organizing factor in the way surface water gets down into the ice”, said Dr. Lampkin. The persistence of buried water in the lake basins has important implications for the evolution of the supraglacial hydrology. Lake basins with persistent melt water resident throughout the winter result in a positive water balance at the start of the melt season, resulting in easily overfilling these basins and the formation of supraglacial channels that enhance the magnitude of surface melt water infiltration into the ice sheet. This work was supported through the extraordinary contributions of two our department’s undergraduates, Casey Joseph and Lynn Montgomery.

Obituary for Eugene Rasmusson
Eugene (Gene) Rasmusson, member of the National Academy of Engineering and highly regarded Research Professor Emeritus of Atmospheric and Oceanic Science was best known for his pioneering study of the observed structure of ocean-atmosphere variations in the tropical Pacific that underpin El Niño. However, his interests encompassed many other environmental problems as well. Indeed, Gene was an interdisciplinary scientist long before it was fashionable to be one. Gene started his professional career at NOAA, but joined the University of Maryland in 1986 as a Senior Research Scientist in what is now the Department of Atmospheric and Oceanic Science. He was appointed Research Professor, with an emeritus rank in 2000. During his years at the University of Maryland he played an important role in fostering the growth of the Atmospheric and Oceanic Science department.
