Coastal habitat mapping of Placentia Bay, Newfoundland
Placentia Bay has been recognised as an important coastal area in the province of Newfoundland and Labrador (NL), both for its socio-economic and ecological importance. It supports a traditional commercial and recreational fishery, an aquaculture industry, a growing oil and gas/shipping industry. Due to its ecological and socio-economic value in the NL province, Placentia Bay was selected as the focus region for a new Government of Canada Coastal Environment Baseline Program, helping establish an environmental baseline that could be used to assess future human impacts and environmental changes.
While specific species have been identified as being of particular importance in Placentia Bay, the more general marine habitat that supports marine ecosystems is key when trying to ensure long-term ecosystem integrity and can be a good indicator of future potential changes in this region. This project aims at improving our understanding of the current status of coastal habitats in Placentia Bay using different approaches. First, multibeam bathymetry will be collected at seven key sites, covering a range of sites of known ecological importance in Placentia Bay. Second, ground truthing data will be collected at those same sites in order to map benthic species distribution and produce benthic habitat maps. Third, high-resolution aerial drone imagery of eelgrass will be collected at several sites in Placentia Bay. Together, those activities will help collect baseline data characterizing both coastal habitats and the distribution of key species in the bay.
