Fin Island & K'yel - 2020 - Airborne Coastal Observatory Data

Fin Island & K'yel # 20-3015-00

The airborne survey covered three sites on the north coast, near Hartley Bay, BC. Collaborators are Bryn Letham, Dana Lepofsky, and the Gitga’at FN. These sites represent important village sites in Gitga’at Territory. Lidar and imagery will be part of an interdisciplinary research program with ecologists and marine biologists studying long-term intertidal harvesting patterns as they relate to resilience and sustainability. The archaeologists (Bryn and Dana) are interested in continuing/expanding the postglacial sea level and paleoshorline study, as well as making beautiful maps for modern beaches, shorelines, and other geomorphological features. Low tide is preferred as there are intertidal features that would be valuable to capture. The project was successfully flown on September 1st, 2020.
