Scientists mapping the sea floor find the weird.

Seafloor mapping also called seabed imaging is the measurement of water depth of a given body of water bathymetric measurements are conducted with various methods from sonar and lidar techniques to buoys and satellite altimetry various methods have advantages and disadvantages and the specific method used depends upon the scale of the area under study financial means desired measurement. Less than 0 05 percent of the ocean floor has been mapped to a level of detail useful for detecting items such as airplane wreckage or the spires. The maps were created through computer analysis and modeling of new satellite data from esa s cryosat 2 and from the nasa cnes jason 1 as well as older data from missions flown in the 1980s and 90s. Sonar has revealed features such as seamounts submerged volcanic peaks which rise 1 000 m 3 300 ft from the sea floor and guyots flat topped seamounts.

Massive field of strange holes discovered on sea floor off ca coast. The smooth flat regions that make up 40 of the ocean floor are the abyssal plain.

The research ship directs sound waves at the bottom and charts the echoes that bounce back to create a detailed map. That was a kind of a weird world of dead rotting carcasses dr o hara said. And in addition to mapping the seafloor they have to bring back images from the deep sea. Just how little do we know about the ocean floor.
