British Columbia Coastal Anchor Marks

The marks left in the seabed by the commercial anchoring process can be seen as linear features in high-resolution multibeam bathymetry data. These features have been digitized to polylines for individual marks and polygons for anchor scour zones for British Columbia's (BC) commercial anchorages. They are made available via the Federal Geospatial Platform (FGP) for use in a Geographical Information System (GIS). This feature dataset is complete for published BC commercial anchorages and the multibeam bathymetry data available in 2021. It does not represent features produced since the collection of each multibeam bathymetry survey nor any features infilled since. The data are intended to be used for scientific research to better understand the cumulative impacts to the seabed from commercial anchoring at a 1:5000 scale or greater.

Description: Title: Digitization -- Description: The anchor scour lines were digitized from available high-resolution bathymetry data. Anchor scour zones were digitized around bathymetry areas that present evidence of seabed disturbance but are not of high enough resolution to delineate individual scours. Please note that not all scours are located within zones of high scouring. See accompanying file for more detail on dataset process steps and methodology.
