Summary: | In coastal subarctic environments such as the fjords of Southeast Alaska, tidewater glaciers can control local hydrology, climatic patterns, ecology, and geologic hazards like landslides and consequent tsunami waves. Documenting and studying glacial retreat in fjords can help scientists understand the dynamic systems that are intrinsically tied to glacial ice processes and forecast changes in these systems. Detailed inventories of glacial retreat have been produced using satellite images and other remote data spanning back to the mid-1900s. However, compiling data on ice positions from before the availability of remotely sensed data requires the existence of historical observations and surveys; oral or written accounts; or geomorphic interpretations using dating techniques such as tree rings or radiocarbon ages. In Glacier Bay National Park and Preserve, Alaska (GBNPP), a rich history of exploration and scientific research has provided us with three centuries? worth of documentary evidence for glacier ... |
