Abstract Large-scale open-pit mining activities have profound impacts on the surrounding landscape and environment. At cessation of mining, rehabilitation large void spaces can be achieved by pit-lake filling, where water body provides a confining pressure mine surfaces, reducing both likelihood slope failure need for ongoing maintenance. Although pit-lakes present range long-term benefits, geo...

Methane ebullition from lakes is an important contributor to atmospheric greenhouse gases. However, typically sampled at intervals greater than the duration of events, limiting our understanding factors controlling this flux. Here, we present high-frequency data a single site in boreal pit lake during open-water season between June 24 and 21 October 2018. We record every 30 min for first 2 mont...

BACKGROUND The Alberta oil sands are an important economic resource in Canada, but there is growing concern over the environmental and health effects as a result of contaminant releases and exposures. Recent studies have shown a temporal and spatial trend of increased polycyclic aromatic hydrocarbon (PAH) concentrations in sediments and snowpack near the Athabasca oil sands operations (i.e., op...

Methanocorpusculum labreanum is a methanogen belonging to the order Methanomicrobiales within the archaeal kingdom Euryarchaeota. The type strain Z was isolated from surface sediments of Tar Pit Lake in the La Brea Tar Pits in Los Angeles, California. M. labreanum is of phylogenetic interest because at the time the sequencing project began only one genome had previously been sequenced from the ...
