The Bjarni Development Study (Petro-Canada, 1983) indicated a very high iceberg scour risk for gas export pipelines from the Makkovik Bank to landfall on the Labrador coast. Re-analysis of the available data identified conservative elements in the 1983 work (King, 2002). Subsequent seabed surveys conducted to define the iceberg scour regime have resulted in over 5,800 km2 of high resolution multibeam on, or near, the Makkovik Bank. This data set contains more than 27,000 analyzed scour features with depth and geometry measurements at over 260,000 cross-sections. Limited repetitive mapping to estimate the iceberg scour formation rate has also been performed.
