AMEC Earth & Environmental is a company that provides assessments and potential solutions for environmental issues. The intern will assist AMEC by creating mathematical models for several environmental projects including the Northumberland Strait ecosystem. A mathematical model will provide AMEC with a tool for assessment of proposed indicators of ecosystem health and forecasting that can be adapted to future environmental projects. Her work is expected to provide direct and immediate benefit to AMEC through improvements to statistical models and computational methods.
The propagation of sound underwater is influenced by variations of the environment in range, depth and azimuth. Many sound propagation models ignore the azimuthal dependence and solve two-dimensional (2D) problem in range and depth. In this project, various mathematical techniques for applying azimuthal dependence into a full 3-D sound propagation model will be investigated. The techniques will be evaluated for computational efficiency when modelling large areas.
