There, the contours of the ocean floor have only been approximated by bouncing satellite radar off the surface of the sea, or by taking low-resolution sonar soundings from boats that passed through the area a generation ago. Research indicates the presence of dramatic vistas, including a volcanic plateau and mountains roughly the height of the Swiss Alps. There is so little bacteria that scientists believe a whale carcass would take decades to decompose down there.
