Approximate location of Emden Deep in the Philippine Trench

The Emden Deep, also known as the Galathea Deep or Galathea Depth, is the portion of 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 Emden in 1927, it was first explored in detail by the Danish ship Galathea in 1951 on the Galathea 2 expedition, from which the name is taken.^[1] Biological samples collected during the Danish expedition demonstrated for the first time that a wide variety of fish, amphipods, echinoderms and bacteria not only survived, but thrived at the deepest parts of the ocean.^[2][3] At the time of the expedition, the Philippine Trench was the deepest known part of the ocean.^[1]

The first crewed descent to the Emden Deep was made by American undersea explorer Victor Vescovo and Filipino oceanographer Deo Florence Onda in March 23, 2021.^[4][5] Findings of the expedition include extensive garbage near the seafloor of the underwater feature.^[6]

It is believed that the most profound depth of the Emden Deep has a pressure reaching 1,054 atmospheres (15,490 pounds per square inch).
