Glaciolacustrine varved sediment as an alpine hydroclimatic proxy

The influence of glacier change on sediment yield, Peyto Basin, Alberta, Canada.

“…The climate-glacier-lake sediment system is complex and strong connections among climate, glaciers, and lakes are difficult to demonstrate (Jansson et al, 2005;Hodder et al, 2007). Identifying a relation between just two variables such as glacier activity and lake sedimentation is challenging enough (Leonard, 1997;Loso et al, 2004).…”

“…Globally, the relation between sediment yield and glacier cover has been shown to be poor (Hallet et al, 1996;Hodder et al, 2007). There are a variety o f factors that contribute to this scatter including regional climate and environmental differences (e.g., geology, slope, aspect), as well as, localized changes to sediment storage.…”

“…There are many interacting and complex environmental processes that can influence the sedimentation in a lake (Hodder et al, 2007). Prior to exploring the cause (i.e., environment) and effect (i.e., sediment yield) relation, the interactions among environmental variables are presented.…”

“…In short, SSY for the Peyto watershed are among the highest in western Canada, yet relatively low among other glaciated watersheds around the world. (Hodder et al, 2007).…”

Late Holocene Glacier fluctuations in southernmost Patagonia.

“…Sediments can also be deposited in proglacial lakes during landslides, floods and other extreme events (Hodder et al, 2007). Any non-glacial sediment sources should thus be identified and accounted for before lake sediments are used to infer glacier activity (Souch, 1994).…”
