Towfish (sidescan and video) and echo sounder surveys were utilized to examine bottom type and macrophyte cover within the area of two coastal marine finfish aquaculture sites, one in New Brunswick (Welch Cove) and one in Nova Scotia (Jordan Bay). Both towfish and echo sounder data could be used independently of one another. However, the towfish data were very useful for ground truthing echo sounder based classifications. All survey data were placed into a GIS which could be used to answer management questions such as the placement of cages at sites, benthic impacts and baseline conditions to determine long term changes.

Dataset includes 8 water quality surveys conducted between May and September 2021 at 4 stations in Hamilton Harbour by the Ontario Ministry of the Environment, Conservation and Parks (MECP) staff. The 4 stations surveyed by MECP are Environment and Climate Change Canada’s 4 long-term monitoring stations in Hamilton Harbour and include centre station and the 3 corners of the harbour. During each survey, water quality samples were collected from 1 metre depth and just above the sediment bed. Depth-integrated samples from the upper or surface layer of the lake were also collected at centre station only.
