"The survey was conducted from a launch fitted with an electric winch, which hauled a wire cable attached either to a 12-in. triangular dredge fitted with a coarse mesh net for qualitative work or a 0.1 m2 Van Veen grab for quantitative work"
12 "miscellaneous molluscs" are also listed: these might or might not be determinate
