A. 4.4.2 Biogeoprocesses along the "Twin mounds" transect
Wheeler, A., Roberts, M.
An ROV dive and box-core sampling were performed (Fig. A4.4.2-1) to compare deepwater
coral habitats that have been trawled and untrawled.
Fig. A4.4.2-1. Location map showing the ROV dive track and location of box-cores.
The dive transect covered 3 small untrawled upslope carbonate mounds. A significant
area of background seabed was then surveyed in transit to the "Twin mounds" to
facilitate on-mound and off-mound biological comparisons. Detailed ROV coverage
was then performed on the "Twin mounds" with abundant evidence of trawling
damage (see section A. 4.8). Box-cores logs are presented below.
