Diamond-bearing kimberlites are enigmatic deposits due to their complex volcanic plumbing systems and variable preservation. Diamond concentrations will vary greatly with deposit-type, however, it is often difficult to effectively distinguish between types (without drilling) due to alteration or poor preservation. Furthermore, while geophysical methods are well established and effective techniques for kimberlite exploration, they require independent and costly constraints (e.g., drill hole data) to limit the number of geologically plausible targets.
Grizzly bears represent a valuable economic, ecological, cultural and symbolic resource for British Columbia. In order to preserve this resource the current population of brown bears needs to be monitored to ensure the health of the population. One marker of health is the genetic health of the population. Genetic monitoring can also tell us important information about how related different bear populations are and how well these populations are adapted to their ecosystem.
Modern weather forecasts are made by computers that solve the complicated equations for air motion, heat, and moisture. Different computer codes, called weather models, use different atmospheric approximations, creating slightly different forecasts. This forecast diversity is good, because the average of all forecasts is often the most accurate, and the spread between forecasts measures uncertainty.
This unique research project, undertaken by Master of Northern Governance and Development (MNGD) students, contributes significantly to our understanding of the North. The research focuses on community-based responses to rapid economic, social, and environmental changes and the development of the local capacity to respond. The analysis is collaborative, involving key stakeholders at the community and multi-community levels, and is informed by their values and interests.
Professionally practicing Civil Engineers and Earth Scientists engage in stream restoration actions in order to enhance freshwater habitats for salmon, trout, and a variety of other species. There is a wealth of procedures and standards available to help practitioners develop design plans. However, there is a lack of specific guidelines to help identify stream reconstruction details that will give the overall effort a greater likelihood of meeting performance expectations and criteria after the project has been constructed.
The Salish Sea is a highly productive, dynamic coastal ocean with substantial temporal and spatial variability at lower trophic levels (e.g. phytoplankton and zooplankton). This variability, in turn, may directly impact resident and migratory fish populations that are of major economic importance in the region. The main goal of this research is to investigate the level of synchronicity between phytoplankton and zooplankton phenology in the Salish Sea.
Reliable measurements of carbon cycling are challenging. Eddy covariance is the technique used by a global network of researchers that measures the net fluxes of gas to and from an ecosystem. However, there are issues with gaps in data under certain environmental conditions. Eosenses eosFD forced diffusion chamber technology allows for long-term, remote and off-grid deployments to measure soil respiration with low power consumption.
Informed decisions on resource management and development require an understanding of how projects will impact the resource, other resources, and the ecosystem. Because the ocean and land are intricately connected along coastal areas, development projects in either will invariably affect the other. However, Ecological Risk Assessments do not consider the two in tandem because the connections between the land and ocean are not well defined and an analytical tool does not currently exist to predict those connections for areas where they have not yet been measured.
Hydrocarbons are hosted in porous sedimentary rocks which were deposited several million years prior to the ingress of hydrocarbons. Once these sedimentary rocks are deposited, other physical, chemical and biological, all termed diagenetic, processes act to modify their original properties. A major product of this diagenesis is cementation. The cement (minerals) occludes (plugs) the pore spaces in the sedimentary rock thus, in general, reducing its capacity to host hydrocarbons. This project, among others will seek to understand the types of cement and their origin in Terra Nova field.
Sedimentary rock formations are currently under consideration for the placement and long-term storage of used nuclear fuel originating from nuclear power generation. A thorough understanding of the long-term geochemical stability in these rock formations is important to prove that future interactions of the waste material with aquifers as well as flora and fauna at the land surface can be ruled out for time periods exceeding 10,000 years.
