Resources may be incorporated into lectures, labs, or other activities.
Postglacial Flooding of the Bering Land Bridge
This geospatial animation shows sea level rising across the land bridge between Siberia and Alaska. During the last Glacial Maximum (~21,000 years ago), the Bering Land Bridge was a vast tundra plain connecting Asia and North America. At that time, the global sea level was 120 meters lower than it is today. Melting ice sheets and glaciers caused the sea level to rise and flood the land bridge. A QuickTime file of this animation can be viewed or downloaded for analysis, education and outreach. Th
Rocky Coastlines and Erosional Landforms

Liberty Ships and Victory Ships, America's Lifeline in War
tells the story of two World War II ship-building efforts. In 1941, with war raging in Europe, President Roosevelt authorized the production of 441-foot cargo ships. These Liberty ships proved too slow and small, so in 1943, a new effort began building Victory ships, which cruised at 18.5 mph, compared to the Liberty's 12.5 mph. By the war's end, the Maritime Commission had built 2,751 Liberty and 531 Victory ships.
