A. 4.5 Box-coring suspected carbonate mound targets Monteys, F.X. Two additional boxcores were taken in transit from the Porcupine Seabight to the Porcupine Bank to groundtruth anomalies on the Geological Survey of Ireland National Seabed Survey multibeam coverage. These were potential carbonate mounds although box-coring found no evidence to support this and both appear covered by hemipelagic muds. Box Core Sample Log Sheet Station No. PS64/279-1 Date 11 June 03 Box Core No. 18 Time of sample 2345 (UTC) SAMS Station No. - Depth (m) 305 Position 52º 03.718N 14º 17.964W Operator T Beck Sample Description Core target, summit of seamount in a newly discovered cluster.
