Annually, large number of tailings samples are collected by operators and sent to laboratories for measurement of Methylene Blue Index (MBI). This procedure is costly, time-consuming, and results are a function of the methods used and personnel expertise. In prior research we developed predictive models for the quick and consistent estimation of tailings MBI from hyperspectral measurements using a limited number of dry samples.
Grizzly bears are an iconic species and the focus of a growing eco-tourism industry in First Nations communities in coastal British Columbia, Canada. Monitoring the effects of eco-tourism and other human activities on bear population health is essential to establish practices that minimally influence bears. This project aims to investigate a novel, rapid approach for monitoring bears using trace amounts of DNA collected from carcasses of salmon chewed on by bears in comparison with the more traditional approach for monitoring bears using hair samples.
Salmon are inarguably one of the most culturally, ecologically, and economically important fish in British Columbia, however, their stocks have been declining since the 1990âs. The Cohen Commission of Enquiry expert panel emphasized that juvenile mortality during the first months at sea was the most likely cause of fishery declines. The two leading agents of mortality are hypothesised to be food availability for growth and pathogen / parasite infection. The Hakai Institute Juvenile Salmon Program is explicitly addressing these two hypotheses.
Diamond-bearing kimberlites are enigmatic deposits due to their complex volcanic plumbing systems and variable preservation. Although geophysical methods are well established and effective exploration techniques, they require independent and costly constraints (e.g., drilling) to limit the number of plausible targets. There is thus a clear need to enhance interpretation of geophysical data to optimize target determination.
The vein-hosted gold deposits in the Bissett area of SE Manitoba have long produced significant amounts of gold and the area has the potential for future substantial discoveries. Given the strong structural control on ore formation, a concerted research effort has been conducted on the structural geology of the deposits. However, there are several outstanding questions, including the genetic relationship between the host rock and the ore.
The efficient monitoring of soil and crop parameters is essential for crop stress evaluation and yield forecast in agriculture, yet most remote sensing studies focus on regional-scale soil and crop parameters estimation using satellite data. Satellite remote sensing is difficult to obtain both high spatial and temporal resolution data with a low-cost in field-scale. Currently, UAV-based remote sensing is a flexible and reliable approach could provide proper data for intra-field monitoring.
Copper and palladium (Cu-Pd) mineralization at the Marathon Deposit are associated with gabbro rocks. It is fundamentally important to be able to distinguish among the different types of gabbros, because only those of the Marathon Series are host to mineralization. This is accomplished through logging drill core, whole rock geochemistry and mineralogy.
Sudbury represents the site of a meteorite impact structure originally greater than 200 km in diameter and that formed 1.85 billion years ago. Despite the proven and potential economic benefits of resource development at Sudbury, there are still major outstanding questions concerning our understanding of the structure and its ore deposits. A series of objectives have been composed concerning the origin of Sudbury Breccia, host to footwall vein deposits, and Offset Dykes at the Post Creek locality and their mineralization.
One of the major issues facing potash mining in Saskatchewan is the potential for water to enter
the mine from water-bearing rocks above mining operations. Rocks near-mine are normally
considered dry and low risk. However, under some conditions, in localized areas, there is the
potential for unsaturated water to have been introduced into the rock formations near the potash
Over the past 25 years researchers at the UBC Geophysical Inversion Facility (GIF) have generated forward modelling and inversion codes that deal with most types of data of interest to a consortium of mining companies. This proposal moves the research to applications in their corporate environments, and to advance the tools and understanding about how to use the research to date in an efficient manner to extract maximum information from their geophysical data. GIFtools, the computing software for carrying out advanced inversion, was developed for this purpose.
