Jackfish Bay was identified as an Area of Concern (AOC) in 1987 due to degraded water and sediment quality and environmental health, which included impairment to benthic communities. As part of the Great Lakes Action Plan, assessments of benthic conditions in the Jackfish Bay AOC have been...

At offshore sites, triplicate Ponar grabs (0.052 m-2) of sediment were collected from the M/V Namao. At nearshore sites, sediment samples were collected from a smaller workboat using a Petite Ponar grab (0.023 m-2) at the 3 m depth contour. Total sampling effort varied across the three years...
