Earth’s Dynamic Surface as Viewed From Space: Using Space Shuttle and International Space Station photographs to observe earth system interactions and environmental changes Joseph F. Reese Department of Geosciences, Edinboro University of Pennsylvania, Edinboro, PA 16444; jreese@edinboro.edu; 814-732-2814 Looking out the window of Space Shuttle Columbia, 1/03 1 Space flight allows humans to view the Earth and the large-scale systems operating on its surface. “Houston, Apollo 11… I have the world in my window.” -- Michael Collins, NASA astronaut 2 Space Shuttle and International Space Station photographs are excellent observational data that document large-scale earth-system processes and interactions. They also show natural and humaninduced environmental changes and hazards working on short time scales. 3 FOCUS ON: GEOSPHERE – Solid Earth PEDOSPHERE – Soils EARTH SYSTEMS, SYSTEM HYDROSPHERE – Water INTERACTIONS, and CRYOSPHERE – Ice ENVIRONMENTAL CHANGES ATMOSPHERE – Air as observed from Space Shuttle BIOSPHERE – Life and International Space Station ANTHROSPHERE – Humans photographs. 4 (All photos used are from NASA Space Shuttle Earth Observations Photography database) GEOSPHERE HYDROSPHERE ATMOSPHERE ANTHROSPHERE BIOSPHERE 5 What do you see? Identify as many features as you can on this International Space Station photo of the San Francisco Bay area! Look for: • San Andreas and Hayward faults • forests, beaches, mountains • urban areas • Alcatraz! • parks, bridges, roadways • internal waves in the Pacific Ocean • tidal channels in the bay • salt collection areas • outflow from bay • what else? 6 Riyadh, Saudi Arabia PROCESSING OF PHOTOGRAPHS -- STEPS: 1.

As regional uplift occurred, river systems such as the Colorado River were rejuvenated, resulting in stream erosion and highly dissected plateaus. Argentina EROSION Glaciated terrains reveal modification of the geosphere by a channelized, flowing (and retreating!) cryosphere. 25 Malaspina Glacier (piedmont glacier) and Yakutat Bay, SE Alaska The Seward Ice Field in the St. Elias Mountains is the main source of ice for the glacier. The glacier moves in surges that internally deform the ice, crumpling medial moraines. 26 EFFECTS OF PLEISTOCENE GLACIATION Fjords along coastline, southern tip of Greenland (drowned glacial valleys) 27 Raised shorelines, James Bay, Canada (isostatic rebound) Iceberg, South Atlantic Ocean, southeast of the tip of South America This iceberg, ~43 mi long and ~21 mi wide, broke away from the Antarctic ice sheet.

With reduced fresh water quantities and constant evaporation, the sea has become more saline and shrunk drastically. It has also become polluted with pesticides and fertilizers. 46 Aral Sea, bisected, 2002 (top to northeast) 47 Pivot irrigation, Saudi Arabia, is leading to groundwater depletion from deep aquifers and to further desertification. Water reserves are finite. Center pivot irrigation systems are ~0.6 mi (1 km) in diameter. 48 Mono Lake, Sierra Nevada, CA Water drawn to supply LA has resulted in lowered lake levels, increased salinity, and an endangered ecosystem.

Are excellent observational data to observe Earth’s dynamic surface and its systems. 2. Document large-scale earth-system processes and interactions. 3. Show natural and human-induced, short-term environmental changes and hazards. 4. Reveal the effects humans have on the Earth’s environment. 5. Are readily accessible and easily downloadable from various NASA websites. 55 56 By using Space Shuttle and International Space Station photographs in the classroom… 1. Increases our understanding of how remote sensing is used to document, interpret, and monitor the surface of the Earth. 2. Incorporates a vast, impressive visual resource under-utilized in geoscience education. 3. Provides a valuable, alternative electronic data set that enhances student learning, especially in technology based activities.
