Jacquelyn (Jackie) Hams is an Assistant Professor of Earth Science at Los Angeles Valley Community College where she teaches Physical Geology, Introduction to Oceanography, Environmental Science, and Planetary Science to many first generation college students. Ms. Hams has a scientific background in environmental and subsurface investigations in terrestrial and marine environments and experience working with Fortune 100 companies as an Environmental Consultant and as a petroleum geologist. Ms. Hams holds a masters degree in Geology and enjoys sailing and outdoor photography.
Vicky Lytle is the Associate Director for Education at the Center for Remote Sensing of Ice Sheets (CReSIS) at the University of Kansas. She leads the Center’s educational component, which collaborates with area schools to provide motivation and encouragement to students to pursue careers in science. This objective is achieved through classroom visits, development of curricular activities, and informal science activities and events. She is excited about establishing a long-term relationship with Ms. Hams to further CReSIS outreach activities and use polar research as a tool to engage students.


A team of researchers and technicians from the Center for Remote Sensing of Ice Sheets (CReSIS) will document conditions at the West Antarctic Ice Sheet (WAIS) divide using a variety of techniques, including weather observations, GPS, ice coring, radar, and seismic sensing. The team characterizes the base of the ice sheet by determining, for example, the amount of water and sediments under the ice, which will be used to help interpret ice core data. Similar measurements over time will contribute to an improved understanding of, and ability to predict, the impact of changes in polar ice sheets on sea level and climate. Additional information about this project can be found at the project website. The project hosted PolarTREC teacher Brandon Gillette in 2007.


The research team will be working at the West Antarctic Ice Sheet (WAIS) drill site, in western Antarctica. The WAIS divide sits on top of 3,485 meters of ice, thicker than nine Empire State Buildings stacked on top of one another! The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves. The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea.

-
GPS:
A Global Positioning System (GPS) is a satellite-based navigation system used to track the location or position of objects on the Earth’s surface.
-
Radar:
A method of estimating the distance or travel speed of an object by bouncing high frequency signals off the object and measuring the reflected signal.
-
Remote Sensing:
The scanning of the earth by satellite or high-flying aircraft in order to obtain information about it.
-
Seismic Sensing:
A procedure that allows for the analysis of lower layers of a substrate through measurement and recording of sound waves transmitted below its surface.
