Protruding sea ice
The blue underside of a slab of sea ice protrudes up through the surrounding ice. Shifting annual sea ice, pushing against the permanent Ross Ice Shelf, creates pressure ridges of uplifted ice.
The National Science Foundation runs the U.S. Antarctic Program (USAP). In addition to maintaining three U.S. research stations 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. (Date of Image: Oct. 16, 2005)
