Controls on Methylmercury Concentrations in Lakes and Streams of Peatland-Rich Catchments Along a 1700 km Permafrost Gradient
Resource
Permafrost thaw may increase the production of neurotoxic methylmercury (MeHg) in northern peatlands, but the downstream delivery of MeHg is uncertain. We quantified total mercury (THg) and MeHg...
Effects of Elemental Sulfur on Soil pH and Growth of Saskatoon Berry (Amelanchier alnifolia) and Beaked Hazelnut (Corylus cornuta) Seedlings
Resource
The land disturbed by open-pit oil sands mining must be restored to support the survival and growth of native boreal plants. Because tailings sand and sodic shale overburden are commonly used as an...
Large Stocks of Peatland Carbon and Nitrogen are Vulnerable to Permafrost Thaw
Resource
Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine...
Microtopography Matters: Belowground CH4 Cycling Regulated by Differing Microbial Processes in Peatland Hummocks and Lawns
Resource
This resource is available on an external database and may require a paid subscription to access it. It is included on the CCLM to support our goal of capturing and sharing the breadth of all...
The Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
Translating the Closure Plan into an Operational Reclamation Programme at Canadian Natural’s Horizon Oil Sands Mine
Resource
Horizon Project reclamation goal is to achieve self-sustaining ecosystems with capability equivalent to predevelopment conditions using locally common boreal forest communities as a guide for reveg
Video - COSIA Design of Experimental Study in Support of Development of a Standard for Fines Measurement in Oil Sands
Resource
Dr. Ron Currie was project lead for a study conducted at NAIT Applied Research Centre for Oil Sands Sustainability (NARCOSS) to help develop a standard for Alberta's oil sands producers to measure...
Video - Flooding of In-line Flocculated Tailings After Thin Lift Drying
Resource
Dr. Aref Najafi is a Technology Development Engineer with Canadian Natural Resources Limited. He described the tailings research at CNRL as they develop an open-pit oil sands mine in NE Alberta. The...
