UNUSUAL REFLECTION EVENTS IN OFFSHORE SEISMIC WORK

Abstract

A number of unusual reflections were recorded during a reflection seismograph survey by the Sun Oil Company in the Gulf of Mexico. These reflections are such as to indicate horizontal travel paths. A limited amount of work was done to try to determine the nature of the reflecting sources. Although conclusive evidence as to their exact nature was not obtained, this work indicates the sources are associated with rather small areas of the Gulf floor. Sonic depth finder recordings over some of these areas can be interpreted as indicating they are small silt filled depressions.
