50,000 years of paleoenvironmental change recorded in meteoric waters and coeval paleoecological and cryostratigraphic indicators from the Klondike goldfields, Yukon, Canada
DownloadFall 2015
A 50,000 year record of meteoric water isotopes (δ2H/δ18O) and paleoenvironmental conditions is presented from syngenetic ice-rich permafrost and macrofossils from eight sites in the Klondike area of central Yukon. Four sedimentary units are recognized based on cryostratigraphy, paleoecological...

Grant, W., Tsui, P., Tripp, D.
The West Interceptor Ditch was constructed to divert water from several small creeks into Bridge Creek, a tributary of Beaver Creek, which eventually flows into the Athabasca River. During the diversion process, a portion of lower Beaver Creek was restructured to accommodate discharge from the...

Exploring the Past, Present, and Future of Predator-Prey Interactions Between Crabs and Their Gastropod Prey
DownloadSpring 2020
Interactions between predators and prey play an important role in structuring their communities and shaping evolution. However, human-induced climate change has the potential to influence both predators and prey and disrupt their interactions. The fossil record provides an enormous resource to...

Observations on the dispersal of saline groundwater in the Beaver Creek Diversion system, 1976-1978
Download1979
Killworth, P.D., Carmack, E.C.
The dispersal of saline groundwater in the Beaver Creek Diversion System is described using data from a two-year physical limnology monitor of the system. Emphasis is placed on processes influencing temporal and spatial patterns in circulation, stratification and saline water distributions....

Response of confined aquatic biota to mine depressurization water in Beaver Creek reservoir
Download1980
Chymko, N.R., Jantzie, T., Noton, L.
Beaver Creek Reservoir was formed as a result of diverting the natural flow of Beaver Creek away from mine and plant areas and southward to the Athabasca River via Poplar Creek. The diversion was initiated in the fall of 1975 with the closure of the Beaver Creek Dam; filling of the reservoir was...

Review and annotated bibliography of stream diversion and stream restoration techniques and associated effects on aquatic biota
Download1978
Stream diversion projects in the Alberta Oil Sands Environmental Research Program study area that have been or will be required in the course of oil sands development are outlined. The effects of stream diversions on aquatic life, natural recovery of stream ecosystems from the effects of...
