Summary(Plain Language Summary, not published)
The nature of the seabed and the subsurface of the Minas Basin is poorly understood; the only known geophysical profiles date to the mid-1960s. The ultimate objective of the research program is to map the entire seabed of Minas Basin using multibeam sonar either from a surface vessel or from an autonomous underwater vehicle. However, in this hypertidal setting, any vessel/AUV mapping campaign requires an upper bathymetric limit to which to survey. Thus, the first step in reaching complete seabed coverage was to map to the lowest possible "depth" (i.e. exposed seabed) during periods of low tide.
