Abstract
The Porcupine Seabight and the underlying Porcupine Basin developed as a failed rift structure when the Atlantic Ocean first started to open 250 million years ago. It is bordered by the Slyne Ridge in the north, the Porcupine Bank in the west and the Goban Spur in the south. The Porcupine Seabight opens to the southwest onto the Porcupine Abyssal Plain. Water depths in the Porcupine Seabight range from approximately 400 m in the north to 3,000 m at its mouth in the southwest. The northern border of the Porcupine Seabight is difficult to define with no clear break of slope but a gradual transition from the Seabight to the Porcupine Bank and Celtic Shelf. With the borders as presented here, the Porcupine Seabight covers an area of 67,100 km2 (Fig. 13.1).
