Moose River

Cretaceous coal-bearing sequences from the Moose River basin in northern Ontario and the Peace River basin in northeast British Columbia were analysed for trace- and major-element contents. Modes of occurrence of the trace elements are proposed on the basis of Pearson correlation coefficients and scanning electron microscopy coupled with energy-dispersive X-ray analysis.The Moose River basin lignite was deposited in an alluvial floodplain environment, and the restricted mineralogy, dominated by quartz and kaolinite, reflects derivation from a highly weathered terrain. The bituminous coal from the Peace River basin was deposited in an alluvial to deltaic environment, with a dominant mineralogy including quartz, illite, kaolinite, mixed-layer clays, carbonates, barite, feldspar, and pyrite.Trace-element contents in both deposits are comparable to the average concentration in United States coals. Modes of occurrence of trace elements in the coals are extremely variable and depend on local conditions both during deposition and subsequently. Association with the organic matter is the most common mode of occurrence of trace elements in the Moose River basin lignites, whereas clay minerals are important trace-element sites in the Peace River basin coal.Factors including coal rank, clay mineralogy, nature of the surrounding rocks, and composition of the groundwaters appear to have important influences on the concentrations of the trace elements and their siting in the coals.

Hydroclimatic Change

Abstract This study analyzed potential hydroclimatic change in the Peace River basin in the province of British Columbia, Canada, based on two structurally different approaches: (i) statistically downscaled global climate models (GCMs) using the bias-corrected spatial disaggregation (BCSD) and (ii) dynamically downscaled GCM with the Canadian Regional Climate Model (CRCM). Additionally, simulated hydrologic changes from the GCM–BCSD-driven Variable Infiltration Capacity (VIC) model were compared to the CRCM integrated Canadian Land Surface Scheme (CLASS) output. The results show good agreements of the GCM–BCSD–VIC simulated precipitation, temperature, and runoff with observations, while the CRCM-simulated results differ substantially from observations. Nevertheless, differences (between the 2050s and 1970s) obtained from the two approaches are qualitatively similar for precipitation and temperature, although they are substantially different for snow water equivalent and runoff. The results obtained from the five Coupled Global Climate Model, version 3, (CGCM3)-driven CRCM runs are similar, suggesting that the multidecadal internal variability is not a large source of uncertainty for the Peace River basin. Overall, the GCM–BCSD–VIC approach, for now, remains the preferred approach for projecting basin-scale future hydrologic changes, provided that it explicitly accounts for the biases and includes plausible snow and runoff parameterizations. However, even with the GCM–BCSD–VIC approach, projections differ considerably depending on which of an ensemble of eight GCMs is used. Such differences reemphasize the uncertain nature of future hydroclimatic projections.

Sediment Data

Very few data are available on the sediment yield of Alberta watersheds especially in the northern portion of the province. In the 175 000 km2 Peace River basin, which covers about 25% of Alberta, sediment data are collected regularly at only four stations. One of these is the 112.7 km2 Spring Creek watershed. In 1977 a pipeline was installed near the mouth of Spring Creek, disturbing an area of about 5000 m2 near the stream channel. The effects of this were to increase local sediment yields by over 1600 Mg in a 4 month period. This compares with regional averages for the Peace River basin of 18–88 Mg∙km−2∙year−1. The study indicates the magnitude of spatial variation of sediment production and shows some effects of geotechnical activities on sediment yields.
