Grounding of sea ice on high latitude continental shelves represents potential threat to maintenance of subsea industrial installations. SCOURBASE system created to store major parameters relevant to engineering design in comprehensive data base format.

Grounding of sea ice on high-latitude continental shelves of the world represent a geologic constraint to safe installation of subsea petroleum faciliaties. To faciliate assessment of seabottom ice scouring on marine design criteria, computerized data-management system has been established for Canadian Beaufort Sea. Side-scan sonar, bathymetric, and sub-bottom profile acoustic data are digitized and computer processed to produce various scour parameters that are incorporated into a compreshensive, location-reference data file.

"In 1990, the ESRF awarded a contract to Canadian Seabed Research Ltd. of Halifax to undertake a large repetitive mapping program in the Beaufort Sea. This program included: designing the survey network, carrying out the survey field work, identifying new scours on the geophysical records, and updating the data base of new scour events."--Introduction.

Presents proceedings of a workshop held to update knowledge of current work and recent achievements in the area of seabed ice scour research. Topics of papers presented include: marine pipeline design in ice environments; engineering aspects of ice gouging; ice scour studies in specific geographic areas; iceberg stability; ice scour models; dynamics of iceberg grounding; seabed dynamics and response to ice forces; ice scour terminology; regional ice scour distribution; ice scour data bases; estimation of ice scour frequency and risk; iceberg scour dating; and ice scour mapping.

This bibliography includes 379 annotated citations to works on ice scour, defined as the disturbance of the bottom sediments of a water body by floating ice. Works describing ice scour conditions in specific locations are arranged geographically by region. Other works are assigned to the following subject categories: theory or modelling of ice scour; and protection of sea-bed structures such as pipelines from ice scour. Includes subject, geographic, author, title, and serial indexes.

Describes a study carried out in 1984 in the southern Beaufort Sea to determine the frequency of ice scour events and to examine the physical changes in a number of selected scours. To identify new ice scours and to determine scour impact rates, a baseline network of good-quality side-scan sonar information was developed for different areas of the Beaufort Sea shelf, incorporating control areas and corridors having the highest degrees of petroleum industry activity. Where overlap occurred with areas surveyed before 1984, interim scour impact rates were calculated. Echo sounding traverses across a given ice scour event at several locations provided data from which transverse and longitudinal scour profiles were constructed. The relationship of scour depth and water depth was also examined, as well as the length, width, and orientation of specific ice scours.
