Thesis Title

Multiscale analyses of the influence of seabed morphology and environmental conditions on the abundance, distribution, and ecology of cold-water corals and sponges in Canada's three oceans

Research Project Description

In trying to improve the knowledge of coral and sponge habitats at a local scale, my research tests the hypothesis that seabed geomorphology, surficial geology and the near-bottom oceanography play a significant role on coral and sponge distribution and abundance and that this relation is scale-dependant. I will derive terrain parameters from high-resolution bathymetry representing the seafloor morphology, to analyse statistically the relationship between seabed characteristics and biological data. In addition, I will compare high-resolution bathymetric data to intermediate and broad-scale data to understand the influence of scale on those relationships. I will then use the gained knowledge to predict cold-water corals and sponges distribution in unsampled locations of the Canadian continental shelf.

Bathymetric data, video data and oceanographic data of cold-water coral and sponge habitats were collected with the Remotely Operated Vehicle (ROV) ROPOS in my two main study areas, off Newfoundland and Labrador and in British Columbia. ROPOS dived between 1000 and 3000 meters depth in the Flemish Cap and the Orphan Knoll (Northwest Atlantic), and between 100 and 500 m depth in three areas of the Strait of Georgia (British Columbia).

Overall, my research should help improve scientific understanding of the relationships between bathymetric complexity, surficial geology, oceanography, and cold-water benthic biodiversity, and the influence of scale on these relationships.
