The GLOBE Cave Protocol Field Guide utilizes existing GLOBE protocols to explore an extreme environment. Caves provide an opportunity to utilize GLOBE protocols to investigate underground environments and compare them to surface environments. Outside the cave, students record elevation, MUC, latitude and longitude, air temperature, relative humidity and air pressure. Inside the cave, students record ... Full description.
