Portland Canal - Work Channel to Nass River

These videos are of a coastal aerial video imaging (AVI) survey conducted in northern British Columbia during 1999 from Northeast Of Somerville Island To Nass River Wetlands.The survey was conducted in support of coastal and land-use management initiatives of the Land-Use Coordination Office (LUCO). The entire survey was conducted during extreme low-tides with tidal elevation seldom exceeding 1m above chart datum during the survey. The surveys may have  used both helicopter) and/or fixed-wing aircraft.The shoreline is imaged with the aircraft (a) to the seaward of the shoreline, (b) at elevations of 75-100m and (c) at an air speed of 100 km/hr. The videographer is in direct communication with the pilot during the survey to optimize imaging of the intertidal zone. Synchronous geomorphological and biological narratives are recorded with the imagery but have been removed from these videos.
