King's Trough even an oblique meteor impact. The trough, being in an apparently geologically stable region, has been studied as a possible location for radioactive waste disposal. King's Trough King's Trough is an undersea trough in the Atlantic Ocean. It is located on the east side of the Mid-Atlantic Ridge, northwest of the Açores-Biscay rise and roughly 400 km NNE of the Azores. It is about 400 km long, running in a NW–SE direction. To the east it branches into the Peake Deep and Freen Deep. The center depth is 4500 m. Surrounding the trough are high ridges and seamounts, such as
Slyne-Erris Trough Slyne Transfer, interpreted to be a splay of the Great Glen Fault. The Corrib Field is situated in the Northern Slyne Basin. In the Central Slyne the 27/5-1 well proved the presence of Late Permian evaporites including salt, possibly indicating fault activity at this time. The basin is interpreted to have been active particularly during the Triassic and Middle Jurassic periods. The Slyne Basin links the Erris and Porcupine Basins. The Erris Trough or Erris Basin is a half-graben that runs parallel with the Rockall Basin and is separated from it by a horst structure, the Erris Ridge. It is
