A drop camera survey of Sambro Ledges, Nova Scotia / by H. Vandermeulen. : Fs97-6/3251E-PDF

"A drop camera system was used to survey bottom type, macrophyte and invertebrate presence on Sambro Ledges (just west of Halifax, Nova Scotia). The nearshore consisted of small islets and reefs with kelp and patches of sand / mud. Deeper regions (30-50 m) were dominated by an extensive reef complex of extreme rugosity and exposure. Many hectares of this reef were covered by coralline algae and a foliose red turf dominated by Ptilota. This turf may be an important factor in determining the types of benthic invertebrates found in the area. Sponges and the tunicate Boltenia were common on the reef"--Abstract, p. vii.
