In the last several years evidence has mounted that a series of abrupt changes in sediment
delivery and palaeoceanography effected the North Atlantic; they are recorded in a variety of …

This text, written by a leading researcher in the field, describes the origin and formation of
lakes in order to give context to the question of how lacustrine deposits form. It explains the …

Fluvial erosion of bedrock occurs during occasional flood events when boundary shear
stress exceeds a critical threshold to initiate incision. Therefore efforts to model the evolution …

Deposits left by continental ice sheets are characterized by sedimentological complexity and
stratigraphic heterogeneity, but stratigraphic descriptions of such deposits, and resulting …

Shortly after 14,500 ybp during the deglaciation of the Laurentide Ice Sheet in eastern North
America, the 80 km wide Seneca-Cayuga paleo ice stream occupied the overdeepened …

Publisher Summary This chapter discusses the advances in the understanding of the
southern Laurentide Ice Sheet (LIS) and its deposits since the publication of the Quaternary …

A succession of elevated ridge deposits on the south Florida margin was mapped using high-
resolution seismic and side-scan sonar imaging in water depths ranging from 50 to 124 m …

Recent advances in the chronology and the palaeoclimatic understanding of Antarctic ice
core records point towards a larger heterogeneity of latitudinal climate fluctuations than …

In south-central Ontario, a Late Wisconsinan regional unconformity consisting of tunnel
channels and drumlinized till crops out north of Lake Ontario. The tunnel channels are …
