When the explorers finally locate a giant squid, they view the organism through glass, and then through a video camera. This publica-tion discusses the performance of the bathyscaphes and second generation manned submersibles in rela- dredging or trawling, but these methods suffer from disadvantages, such as environmental damage and nonselective sampling. Bathyscaphes can dive deeper than a person with scuba gear, and even deeper than submarines. Currently, most exploration is performed in manned or remote-controlled submarines, with unmanned submarines performing surveillance. When that happens, water seeps into the motor, rendering it useless until it is repaired. Woods Hole Oceanographic Institution. . The advantages Like an electric car, a conventional modern EB can be either pure electric or hybrid. Because light traveling underwater is affected by greater attenuation and backscatter, hundreds or thousands of images are required to adequately cover large areas. submersibles were known to be stationary, we have been able to verify the accuracy of the tracking system to within 16 m.
