Out there with the camera are hydraulics, thrusters, and hundreds of other essential parts that will keep us safe. Scientists use sound waves to acoustically map the shape of the seafloor and locate seamounts and knolls.

Wherever we look at these undersea mountains, our sampling robots and nets bring up creatures we have never seen before. The structure and distribution of coral reefs.

The theory also predicts that larger seamounts are expected to host larger and more diverse communities than smaller seamounts. Richer de Forges, B. The velocities of oceanic currents, including the East Australian Current, were also measured - these datasets can be used for oceanographic research. This loose structure provides a porous environment within seamounts that is believed to provide habitat for sulpher-reducing bacteria, and also gives rise to unstable slopes subject to massive slumping of debris flows Malahoff, 2006.

Many people are surprised to learn that corals, in particular, are found in such deep, dark, and cold places. It's also in part due to the vast size of the ocean.

For example, in the Tonga-Kermadec arc comprising the fastest moving pieces of ocean crust on earth; Bevis et al. About 16,000 km 2 was mapped over 16 volcanoes, representing an area seven times as large as the Australian Capital Territory or half the size of Belgium.

Lophelia, Candidella, and solitary cup corals with brittle stars, crinoids, and various sponges found during a 2004 NOAA expedition to a seamount chain off the coast of New England.

Thanks to the steep slopes of seamounts, nutrients are carried upwards from the depths of the oceans toward the sunlit surface, providing food for creatures ranging from corals to fish to crustaceans. A diver pokes through the bubbles to make a final adjustment to the camera housing mounted on the outside of the sub.

Lophelia, Enallopsammia stony coral, dead coral skeleton, ruffled sponges with purple Trachythela octocoral growing on dead coral skeleton. For these reasons we might expect recruitment to be infrequent and episodic, punctuated with hiatuses of non-recruitment periods. The acceleration of currents over obstacles on the seabed is a function of their height in relation to the depth of water, as well as to their orientation with respect to the current for non-symmetrical features.

Therefore, the larger a feature is with respect to the depth of water in which it occurs, the more it will interact with currents and cause local flow acceleration the absolute flow speed varying as a function of the speed of the ocean current being deflected.
