Resuspension of sediment by bottom trawling in the gulf of Maine and potential geochemical consequences
Article Abstract:
The environment of the Gulf of Maine is distinguished by a thick and basin-wide nepheloid layer. The commercial bottom trawling of the region is strongly affecting measured resuspension fluxes and contributing to the maintenance of the nepheloid layer. The impact of trawling is severe and produces changes in the environment and soft-sediment infaunal communities.

Effects of experimental otter trawling on surficial sediment properties of a sandy-bottom ecosystem on the Grand Banks of Newfoundland
Article Abstract:
Researchers conducted a 3 year study on the impact of otter trawling on benthic habitat and communities in the Grand Banks of Newfoundland. The 13-km-long corridors are trawled 12 times a year, which creates a disturbance zone of 120 to 250 m wide. The study revealed that trawling reduces surficial biogenic sediment structure and the abundance of organic matter.
