Changes in sea-level are attributable mainly to crustal deformation, changes in global ocean volumes (eustasy) and the response of the Earth's crust to glaciation (isostasy). On the British Columbia coast, sea-level history is complex owing to regional differences in these factors. A geographic data gap exists in our understanding of Holocene (past 10,000 years) sea-level change and landscape evolution along the central coast. The proposed research will help close this gap, by studying post-glacial sea-level and landscape response on Calvert Island.
Recent advancements in TEM sample preparation techniques using the latest generation of dual focused ion and electron beam (FIB-SEM) instrumentation allows for high-resolution examination of textures, elemental composition and structures of minerals at unprecedented resolution. These instruments enable the extraction of FIB-prepared TEM foils at any desired location of the sample (Wirth, 2004, 2009).
When using geophysical methods to gain insight into the structure of earth, large geophysical data sets are collected. Since the earth is a 3D structure, the data must be interpreted and processed in 3D to be of the most value in the exploration process. This research will develop the capability to invert large gravity, magnetics, and airborne EM datasets accurately and in a reasonable timeframe. This requires the research and development of inversion software, data visualization and QC software, and inversion setup scripts.
Features identification and extraction from remotely sensed (RS) image is an ongoing research endeavor and has wider applications. Traditionally it has been based on pixel-based image analysis which has proved to be inefficient and ineffective especially for very high resolution (VHR) data. More recently object-based image analysis (OBIA) has gained a wider recognition because of its potential for accurately extracting objects from RS data corresponding to real-world features.
Carbonate hosted hydrothermal ore deposits commonly develop narrow mineral alteration (i.e. visible) haloes, complicating exploration targeting. In contrast, hydrothermal modification of the country rock’s stable isotope composition usually extends far beyond visible alteration. Hence, stable isotope “mapping” is an effective tool to aid exploration for carbonate hosted deposits. However, widespread utilization of stable isotope data has been hampered by its high cost and long turn-around times.
A lack of physical infrastructure and the corresponding fear of harm are a significant barrier to urban cycling, and an impediment to the expansion of Curbside Cycle’s target demographic. Using outreach and education through a collaborative process involving partners Curbside Cycle and Cycle Toronto we will empower local experts, enlist local businesses as powerful community stakeholders, and foster coalitions of community support for improved bicycle infrastructure.
Les feux de forêts naturels sont les perturbations majeures à la base de la dynamique végétale boréale. Les changements climatiques induiront une augmentation des régimes de perturbations. Les régimes de perturbations, la structure et la composition forestière pourraient se diriger vers une variabilité naturelle différente de celle connue précédemment.
This project will carry out original research of a prospective lode gold system located on the western shore of Hudson’s Bay. The location is near the hamlet of Whale Cove. The gold mineralization is intrusive-related, very similar to that of the well known deposits of the Porcupine and Kirkland Lake camps of the southern Abitibi. The research specifically addresses the timing of gold mineralization within the context of related host rock alteration. Currently, there is considerable debate over a Neoarchean or Paleoproterozoic age of mineralization.
There are however, a range of GCMs, future climate scenarios and downscalingtechniques that can be used and each yields different results. Due to this uncertainty, itis regarded as best-practice to use a collection of individual projections to develop“ranges” that characterize future climate conditions. The aim of this internship is toconduct this analysis for the variables of precipitation and temperatures, which will beused directly by the HCA in their assessment of impacts and hydrologic modeling
