Where is Molloy Deep (aka Molloy Hole)? What is its greatest depth?

The Molloy Deep was formed by gas explosion craters and lies 170 miles west of Svalbard, Norway. Three successful dives took place over the course of three days. Victor Vescovo went by himself to complete the first manned dive to the bottom of the Molloy Deep, reaching a bottom depth of 5,550 metres.

The Molloy Deep is a roughly rectangular, seismically active,[11] extensional,[12] sea-floor basin, that lies between the northwestern tip of the Molloy Fracture Zone,[13] (a right-lateral,[14] strike-slip fault[14]), and the Spitsbergen Fracture Zone (also a right-lateral, strike-slip fault). These two fracture zones connect the Knipovich Ridge (the actively spreading northern segment of the Mid-Atlantic Ocean ridge system), with the Lena Trough, an actively spreading mid-ocean ridge region north of the Spitsbergen Fracture Zone. The Lena Trough joins the southwestern end of the Arctic Ocean's Gakkel Ridge[15] which is the slowest spreading mid-ocean ridge on Earth,[16][17] and which stretches across the entire Arctic Oceans’ Eurasian Basin.[18]
