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 eubing 
in the basement beneath Georges Bank.
