The Sigsbee Abyssal Plain is probably fed in part by canyons leading from the east coast of Central Mexico and out of the Bay of Campeche (Ewing, Erieson and Heezen, 1958). Over 10 m of fine silt was deposited on the Sigsbee Abyssal Plain during Wisconsin time (Ewing et al., 1958). Rates of sedimentation exceeded 60 cm/ 1000 years during the Wisconsin but have averaged less than 8 cm/1000 years in Recent time. A number of small topographic prominences of about 6 fm
