The enormous submarine canyon located off the coast of central California in Monterey bay is very well studied for both its geologic and biologic features, as well as being a national marine sanctuary. Thus, "Monterey" is the correct filler to be used here.
<h3>What is a Submarine canyon?</h3>
A submarine canyon is a steep-sided valley that has been dug into the seabed of the continental slope; it can occasionally extend deep over the continental shelf, have virtually vertical walls, and can have canyon walls that are up to 5 km high, like the Great Bahama Canyon. Submarine canyons provide routes for the movement of turbidity currents over the seafloor, just like above-sea level canyons do for the movement of water through land.
Rivers may provide turbidity currents or storms, and undersea landslides, earthquakes, and other soil disturbances may create them on the seafloor. Turbidity currents are movements of water that are thick and sediment-laden. The continental slope is eroded by the swift (up to 70 km/h) turbidity currents that flow downslope.

However, this could harm the ocean because any incidence of oil spill from the drillng could cause a serious harm to the ocean environment and life.
