| Abstract |
This paper results from a high-frequency, seismic-reflection survey of Lake Superior sediments and delineates the general pattern of late and postglacial sedimentation within much of the lake. The seismic profiles reveal where sedimentation has been most rapid during the past 10,000 yrs and where bottom currents and other factors presently affect sedimentation in the deep-water environment. |
