The MBARI Eel River Basin survey is just west of a region that has been the focus of a large integrated program to study the formation of sedimentary strata on continental margins known as the STRATAFORM program. The program website has additional mapping data for this area and links to related sites. Much of the work in the area has been presented in a special issue of the journal, Marine Geology (1999), vol. 154, edited by C.A. Nittouer. The region we surveyed shows the head of a small submarine canyon starting at about 600 meters depth. Several areas with high backscatter are carbonate pavements associated with cold seeps, some still active. At the outer edge of the survey, at about 750 meters depth, the 100-meter tall hill is probably a breached anticline. It may also be associated with low-temperature fluid flow, since the bottom has high backscatter characteristic of carbonate pavement.
