The Gravity Field and the Magnetic Field On the basis of the relatively irregular gravity field shown by a series of closely spaced pendulum observations in the Bay of Biscay, Browne and Cooper (1950) concluded that there must be large topographic features buried beneath the Bay of Biscay Abyssal Plain. Subsequent studies of the Madeira Abyssal Plain with a continuous-recording Graf sea gravimeter gave further support to this conclusion (Worzel, 1959) (Fig. 31). In the region of the adjacent

The Gravity Field and the Magnetic Field On the basis of the relatively irregular gravity field shown by a series of closely spaced pendulum observations in the Bay of Biscay, Browne and Cooper (1950) concluded that there must be large topographic features buried beneath the Bay of Biscay Abyssal Plain. Subsequent studies of the Madeira Abyssal Plain with a continuous-recording Graf sea gravimeter gave further support to this conclusion (Worzel, 1959) (Fig. 31). In the region of the adjacent continental rise, the free-air gravity curve is by and large a perfect reflection of the topographic })rofi]e. However, on the abyssal plain the gravity field sliows variations of the same amplitude as those observed over the adjacent. 4000.
