520 |a"This illustrated map depicts acoustic backscatter strength, in shaded relief view, part of a three-map series of Lunenburg Bay at a scale of 1:25 000. Backscatter is derived from 2004-06 sonar surveys and displayed as a blue (coarse) and beige (finer) colour spectrum. Sample, grainsize and geophysical control is summarized in a map insert as is a summary of the bay's oceanographic conditions. Although there is no simple relationship between backscatter amplitude and surficial sediment type, together with grainsize, it is the primary guide for mapping seabed sediment type. Bedrock and bedrock with gravel cover is abundant while sand is common in bedrock crevices. Sand and mud is common the central mid-bay and the more energy-sheltered innermost bay. Tidal currents dominate at the head of the bay but wind, waves and associated currents, paralleling the coastline, are capable of sand transport, sometimes in small dunes. Coastal erosion contributes to harbour-filling muds, but storms also flush sediment to deeper waters"--Summary provided by publisher.
