Preliminary Interpretation of Seismic Data from Lower Cook Inlet, Alaska

Michael A. Fisher


Marine seismic data from lower Cook Inlet, Alaska show two strong reflections that have been interpreted as returns from erosional surfaces and a third reflection that represents the acoustic basement in these data. From indications in the seismic data, shallow reflectors onlap to the northwest; deep reflectors onlap to the southeast. The major structural feature in lower Cook Inlet is an east-trending transbasin arch here informally named the Augustine-Seldovia arch. Anticlines smaller than the arch trend approximately northeast and may offer good structural traps for petroleum where they intersect the arch.
