The Bay of Fundy contains a variety of sandbodies with large-scale bedforms impressed upon them. One of the most striking of these is the Cape Split sand body of the Minas Channel (Figure 1), the body of water which serves as an anteroom separating the Minas Basin from the main Bay of Fundy. It is partitioned off from the Minas Basin by a parabolic, synclinal cuesta of Triassic basalt, with Cape Blomidon at the elbow and Cape Split at the tip of the cuesta. Pleistocene subaerial erosion and Holocene tidal scour have cut a trench through the glacial outwash flooring the Minas Passage (Figure 2), into the underlying Carboniferous sandstones and shales. The trench is locally as deep as 150 metres below sea level. The sandbody occurs on the flat floor of Scot's Bay on the 30-metre-deep lip of the trench, 3.7 km west of Cape Split.

NOAA (National Oceanic and Atmospheric Administration) is the arm of the United States Government charged with environmental research and mapping of the continental margin. Its.. response to the recent and growing public concern with management of the marine environ ment has been the formation of the MESA (Marine Ecosystems Analysis) Program. MESA is a NOAAwide task force. Its administrators are attached to NOAA headquarters in Washington,, D.C., but its staff consists of scientists and engineers from NOAA Laboratories across the country. Participating units include at pres ent Atlantic Oceanographic and Meteorological Laboratories, Miami; the Middle Atlantic Coastal Fisheries Center, Sandy Hood, New Jersey; Engineering Development Laboratories, Miami; the NOAA ship FERREL, and the Environ mental Data Service, Washington, D.C. These in-house investigators and support personnel serve as a cadre for a larger body of academic, governmental and industrial investigators.
