Story: Sea floor geology

Continental slopes

Continental slopes

This is a three-dimensional view of the seabed off Tokomaru Bay, north of Gisborne. The flat, gently sloping continental shelf extends offshore to a depth of about 130 metres. The steep continental slope plunges down the seamount-studded deep ocean floor at 3,000 metres below sea level. The base of the slope represents the edge of the New Zealand continent.
