Interactive animation showing the changes occurring to an ice-shelf in relation to the temperature of the surrounding water. The animation has been created on the basis of the most recent models created by the modelling team of the antarctic research called ANDRILL.
What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.
In 1978, scientists predicted that global warming would lead to a disintegration of Antarctic Peninsula ice shelves. Space-borne data indicate that this prediction may be coming true. In these before and after images, note the dramatic change in the apparent shoreline. Scientists captured the first image using the ERS-1 satellite in 1992. As seen in the second image, collected by RADARSAT in 1997, huge changes have come to the coastline. In 1995, a 2000 square kilometer section of the ice shelf collapsed into thousands of fragments that eventually drifted out to sea. Researchers are still debating why the ice shelf broke up so dramatically, and what significance the break up has for interpreting local versus global changes to the environment. Theories include a series of warmer than usual summers which may have caused high levels of surface melting, or an overall climate warming trend.
This video segment adapted from NOVA uses microwave images to reveal how sea ice doubles the size of Antarctica each winter. Rare footage shows how sea ice crushed the famous ship Endurance in 1914.
Beyond Penguins and Polar Bears is an online professional development magazine which focuses on preparing elementary teachers to teach polar science concepts while also integrating inquiry-based science and literacy instruction. The project draws on research showing that an integrated approach can improve student achievement in science, as well as in reading comprehension and oral and written discourse abilities. Ultimately, the project seeks to bring the polar regions “closer to home” for elementary teachers and their students.
The Ohio State University's Library web site notes As a navigational aviator, Byrd pioneered in the technology that would be the foundation for modern polar exploration and investigation. As a decorated and much celebrated hero, Byrd drew popular attention to areas of the world that became focal points of scientific investigation in numerous disciplines.
