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
