Abstract
A coarse grid of 480 kilometres of seismic lines was collected in lower Cook Inlet, Alaska between Homer on the north and Cape Douglas on the south. Paper and mylar copies of the seismic sections and shot point maps are available to the public from NOAA in Boulder, Colorado.
The seismic data shows two strong reflections that have been interpreted as returns from erosional surfaces and a third reflection that represents the acoustic basement. From indications in the seismic data, shallow reflectors onlap to the northwest; deep reflectors onlap to the southeast. A 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.
