"During 2007–10, a series of midwater trawl surveys was conducted, at meso- and bathypelagic depths, in The Gully, a submarine canyon and Marine Protected Area immediately east of Sable Island, and around the canyon’s mouth. One of the major outputs of that program, appearing in the primary literature, is a multivariate statistical analysis of the structure of the fish assemblage. That work is here supported by supplementary information on the preparation of the data matrices for the multivariate analyses and by examination of both the spatio-temporal distribution and the length frequency of each of the 19 species included in the analysis. The examination revealed up-canyon trends in fish abundance (declining in 17 species), in depth distributions and in average lengths (increasing in 10 species – usually because of a rapid up-canyon decline in numbers of small individuals)"--Abstract, p. v.
