Paleo Slide Set: Low Latitude Ice Cores: High Resolution Records of Climatic Change and Variability in the Tropics and Subtropics International team of scientists involved with research. Low latitude, high altitude ice core programs such as Quelccaya and Dunde require international cooperation with individuals from several nations working together to achieve a common goal: increased understanding of Earth's climatic system. Putting politics aside, researchers operate in a truly international scientific community, one whose only boundaries are those of knowledge.
