In all, 37 taxa of deep-water corals were identified in the study area: 21 alcyonaceans including the gorgonians , 11 pennatulaceans, 2 solitary scleractinians, and 3 antipatharians. The greatest diversity of coral species was on the Flemish Cap.
Corals were most abundant along the continental slope, between and m depth. Soft corals alcyonaceans , sea fans gorgonians , and black corals antipatharians were most common on bedrock or gravel, whereas sea pens pennatulaceans and cup corals solitary scleractinians were found primarily on mud.
The biomass of deep-water corals in the bycatches was highest in previously lightly trawled or untrawled areas, and generally low in the regularly fished grounds. Figure 1. Open in new tab Download slide. Table 1. Substratum types based in Wentworth grade classification.
