More than 170 eighth-graders from Boulder's Southern Hills Middle School visited the Institute of Arctic and Alpine Research (INSTAAR) and the National Snow and Ice Data Center (NSIDC) on Tuesday, April 24, for an excursion involving lab tours, talks, science games and a field trip along Boulder Creek. The eighth-graders sampled the aquatic insect life along Boulder Creek during the visit as part of an ecosystem education project coordinated by INSTAAR. They also toured INSTAAR's sediment, radiocarbon, stable isotope, dissolved organic matter, pollen and tree-ring dating labs. The event included talks by INSTAAR faculty on global warming and the Arctic, the archeology of glaciers, life in Russia 40,000 years ago, and volcanoes in Antarctica. The Southern Hills students also toured facilities at NSIDC, which conducts research around the world and archives and distributes data on snow, avalanches, glaciers, ice sheets, sea ice and ice cores.
