Abstract

This survey combines the use of digital video camera technology with real-time GPS mapping to image the shoreline of areas in southeast Alaska: Icy Strait, Lynn Canal, Yakutat, and Sitka, at low tide. The unusual features of the survey are: (a) the survey was conducted during the lowest tides of the year so the entire intertidal zone is imaged; (b) the technique is not weather dependent so imagery can be collected in any conditions under which aircraft can fly and; (c)both a coastal ecologist and coastal geomorphologist were in the aircraft providing real-time commentary on intertidal features that may not be visible on the imagery.
