The Galathea Depth is the portion the 10,540-metre-deep (34,580 ft) Philippine Trench exceeding 6,000-metre (20,000 ft) depths in the south-western Pacific Ocean. Originally discovered by the German ship Planet in 1912, it was first explored in detail by the Danish ship Galathea in 1951 on the Galathea 2 expedition, from which the name is taken. Biological samples collected during the Danish expedition demonstrated a wide variety of fish, amphipods, and bacteria surviving at depths seldom seen before.
