SEEP GAS PLUMES MAPPED WITH SONAR
Figure 1 of Quigley et al. (1999). Offshore Coal Oil Point study area. Fault locations and anticline-syncline pairs in Monterey and Sisquoc Formations of northern Santa Barbara Channel shelf determine seep distribution. Mapped distribution of seepage is from a 3.5 kHz sonar survey during August 1996. Area of seepage comparison is boxed 13 km2 area surrounding Platform Holly. Arrow points to sonar profiles in Figure 2 in Quigley et al., (1999).
