Seafloor stability study, inner scotian shelf

Describes a measurement program designed to monitor the behaviour of sea floor sediments on the Scotian Shelf under winter storm conditions. Four measurement sites were spaced along a transect line running seaward from Martinique Beach, Nova Scotia, on a bearing of approximately 156 degrees. One site was located on gravel in 30 metres water depth, and the other three were on sand in depths of 20 to 37 metres. The main measuring device used was a rod driven into the sea bottom onto which was placed a specially designed washer assembly to monitor changes in sea floor elevation with time. Other equipment included video and time lapse cameras, chain-type scour detectors, current meters, and a box corer. Results are presented regarding sea floor scour and accretion, bed form measurements, sediment grain size analyses, oceanographic conditions, and anomalous sea floor depressions.
