TL;DR: In this paper, simple insights from the physics of ice, water and sediment place constraints on the possible sediment-transport behavior of glaciers and ice sheets, and several sediment-entrainment mechanisms may be active beneath a single glacier, but one process is likely to be dominant at any place and time.

TL;DR: In this paper, a synthesis of traditional and recently published work regarding the origin and evolution of the Great Lakes is presented, focusing on three topics critical to the development of the great lakes: the glaciation of the watershed during the late Cenozoic, the evolution of lakes since the last glacial maximum, and the record of lake levels and coastal erosion in modern times.

TL;DR: In the case of the Matanuska Glacier as discussed by the authors, sediment is trapped by this growing ice, forming stratified debris-laden basal ice, and the large sediment fluxes that this mechanism allows may have implications for interpretation of the widespread deposits from ice that flowed through other overdeepenings, including Heinrich events and the till sheets south of the Laurentian Great Lakes.

TL;DR: Bermuda is a stable, mid-oceanic carbonate platform for which a particularly complete record of Late Pleistocene eustatic sea-level fluctuation has been reconstructed from a detailed study of geological field relationships combined with an extensive programme of U-series and amino-acid racemization geochronology as discussed by the authors.

TL;DR: It is found that the long profiles of beds of highly erosive glaciers tend towards steady-state angles opposed to and slightly more than 50 per cent steeper than the overlying ice–air surface slopes, and that additional subglacial deepening must be enabled by non-glacial processes.
