Sigsbee Deep
submarine feature, Gulf of Mexico
Quick Summary
Sigsbee Deep is the deepest point in the Gulf of Mexico, reaching a depth of 17,070 feet (5,203 meters). It is located within the Mexico Basin, a large, triangular-shaped area of the Gulf's floor. The basin lies northwest of the Campeche Bank. Despite containing the deepest point, the Gulf of Mexico is generally quite flat, with a very gradual slope. The Sigsbee Knolls, a series of hills believed to be caused by underlying salt domes, are found in the middle of the Mexico Basin.12
