Abstract
Seamount Jasper rises 1,900 fathoms above the 2,200-fathom ocean floor, about 320 nautical miles SW of San Diego, California. Gravity-anomaly measurements of the seamount and surrounding area show that 1) if an average rock density of 2.3 gm./cc. for the seamount is assumed, there is no anomalous mass beneath the seamount, and 2) a regional mass deficit equivalent to 20 mgal. attraction surrounds Seamount Jasper. Possible explanations are discussed.
