Abstract:

Elson Lagoon is a key site in the Arctic Coastal Dynamics (ACD) program. There are 14 shoreline transects that run perpendicular to the coast which are used to assess annual and inter-annual rates of change. These transects are marked on the ground with labeled benchmarks. The transects are used to cross-check Differential GPS surveys of the shoreline sections A, B, C and D (note corresponding shoreline change polygons available as GIS shapefiles.) This Excel Spreadsheet summarizes field data measurements collected. Since 2002, the distance from fixed markers along these linear transects to the coastal bluff and thaw depths have been measured. GPS waypoints are used to navigate to the benchmarks which mark each ACD line transect. Distances are measured from the inland benchmark to the edge of the coastal bluff using a measuring tape. The tape is set on top of the inland benchmark and aligned with the interim markers (or stakes) which extend toward the bluff. The total distance from the inland benchmark to the edge of the coast is recorded. Thaw depth is probed every 10 meters from the inland benchmark (meter 0) to the bluff edge. Measurements are taken twice along each side of the tape. Photographs are taken from the inland benchmark looking across the transect to the bluff edge. Photographs are also taken from the bluff edge looking back toward the inland benchmark. Fixed locations for photo documentation along the lagoon have been problematic due to erosion, but should be established in the future. These could be offset from the 14 transects for comparative change analysis.

Purpose:

Mapping is performed to monitor shoreline erosion along Elson Lagoon which is a key site of the Arctic Coastal Dynamics (ACD) program and Arctic Circum-polar Coastal Observatory Network (ACCO-Net).
