Seismic stratigraphy of Waterton Lake, a sediment-starved glaciated basin in the Rocky Mountains of Alberta, Canada and Montana, USA

Late Pleistocene and Holocene depositional history of sediments in Flathead Lake, Montana: Evidence from high-resolution seismic reflection interpretation

“…In general, the depositional history of Flathead Lake is typical for a lake basin recording the transition from glacial to post-glacial conditions. Thick late-glacial glaciolacustrine sediments are overlain by a thinner package of fine-grained Holocene deposits (Glenn and Kelts, 1991;Eyles et al, 2000). The infill is dominated by a thick succession of glacial till (unit A) and glaciolacustrine sediments (unit B) both immediately related to glacial activity in the lake basin.…”

“…5E). The drape-like geometry of units F and D suggests deposition of very fine-grained sediments by slow suspension settle out (Eyles et al, 2000). Although unit E does not display this drape-like geometry, its acoustic character and internal sedimentology also suggest deposition of fine-grained suspended sediments.…”

Fewer such studies have been conducted in the western and northwestern part of North America (Eyles et al, , 2000Mullins et al, 1990Mullins et al, , 1991Eyles and Mullins, 1997) despite an abundance of glacial lakes. The purpose of this paper is to discuss the late Pleistocene and Holocene syn-and post-glacial history of Flathead Lake in northwestern Montana.…”

Lake bed geomorphology and sedimentary processes in glacial lake Windermere, UK

“…Glacial lakes often occupy these basins, and often contain a comprehensive record of late-glacial and post-glacial sediments (Pennington, 1978;Eyles et al, 2000). Lacustrine sediments further provide a high-resolution record of sediment provenance, biological history, catchment level anthropogenic activity and climatic and environmental change.…”

A side-scan sonar and high-resolution Chirp sub-bottom profile study of the natural and anthropogenic sedimentary record of Lower Lough Erne, northwestern Ireland

“…The remote sensing techniques employed to investigate the geophysical properties of the Lower Lough Erne Basin include highresolution Chirp sub-bottom profiler and a side-scan sonar system. The Chirp sub-bottom profiler is used to record continuous vertical sedimentary sequences of the lake basin, according to their acoustic reflectivity, to depths of approximately 30 m. Assessment of high-resolution sub-bottom data has greatly improved understanding of the evolutionary history of many lakes [8,16,25,31,38,51] and has also proved valuable in underwater archaeological investigations [44,45,46]. Sidescan sonar systems provide a graphic representation of how materials on the lake floor interact with acoustic energy.…”
