The Five Deeps Expedition is the first manned expedition to the deepest points in each of the world’s five oceans. Transects across trenches yield asymmetric profiles, with relatively gentle (~5°) outer (seaward) slopes and a steeper (~10–16°) inner (landward) slopes. This asymmetry is due to the fact that the outer slope is defined by the top of the downgoing plate, which must bend as it starts its descent. The SAN plate is bounded to the west by the East Scotia Ridge and to the east by a subduction zone.
