Collecting igneous rock samples in Antarctica

Johns Hopkins graduate student Karina Zavala breaks up a sample of igneous rock for study

Johns Hopkins graduate student Karina Zavala breaks up a sample of igneous rock from the McMurdo Dry Valleys, Antarctica. Zavala's research group, led by Bruce Marsh, brought more than 1,000 pounds of rocks back to the U.S. from Antarctica for further study.

The National Science Foundation runs the U.S. Antarctic Program (USAP). In addition to running three, year-round U.S. research stations--McMurdo Station, Amundsen-Scott South Pole Station and Palmer Station--on the continent, USAP supports research projects in an array of scientific disciplines including, for example, aeronomy and astrophysics, biology and medicine, geology and geophysics, glaciology, and ocean and climate systems. Outreach such as the Antarctic Artists and Writers program and education programs are also supported. For more information about USAP, visit the program's website Here.
