Ecosystem Function, EF-07: Ecosystem Health and Habitat Complexity

The main objective of this project is to quantify the landscape structure of Arctic intertidal habitat for statistical comparison to faunal diversity and geophysical variables. Focus is on the intertidal and shallow sub-tidal zone, obtaining the resolution of landscape features through airborne remote sensing and image classification to resolve habitat features at the landscape or larger scale.

The specific aims of the project are:

1. Map arctic intertidal landscape using aerial photography; collect concurrent sediment and macrofaunal samples

2. Quantify landscape structure through image analysis and multi-scale spatial statistics

3. Explore the relationship between landscape structure, geophysical variables, and benthic community This project responds to DFO Habitat

Management needs for describing the ecosystem at greater than local scales and employing an ecosystem-based management approach to address coastal impacts.
