A STUDY OF AEROMAGNETIC DATA, NEW ENGLAND SEAMOUNT AREA,
Abstract
A detailed aeromagnetic survey of a 38,000 square mile area off the coast of New England was conducted by the Oceanographic Office in 1957. The survey area contains the continental shelf, slope and rise related to Georges Bank, and the northwest end of the New England-Bermuda seamount chain. Analysis of the survey data indicates that the features included in the group extending from Kelvin to Bear seamounts are highly magnetized, in the order of 0.01 cgs units, and that the seamounts have little sedimentary cover. The nature of the magnetic anomalies over the seamounts extending from Panulirus to Mytilus indicates that these features are composed of a less magnetic material. Based on the correlation between magnetic anomalies and bottom features, it is probable that the survey area contains several seamounts or seaknolls that are at present uncharted. The anomalies over the continental margins are linear in form and reflect structural trends and possible faulting in the basement beneath Georges Bank. (Author)
