Scientists have recently published an updated version of the map of ocean floor. The map was shown in relation with a study published this Thursday. According to the research, the investigators revealed a new map which is twice as bona fide as the old map- the latter one was brought together approximately two decades back. The resolution the previous map provided was of structures that were a mile and high and bigger. This time the scientists got succeeded in assembling a high resolution map revealing number of volcanoes hidden under sea unknowingly.
The lead investigator David Sandwell, a geophysics professor at the Scripps Institution of Oceanography at UC San Diego described his findings saying that in the past only 5000 archaic volcanoes were seen but now they are able to witness 10,000. He further stressed that may be his conclusion seemed to be useless but having so little information about the ocean floor, this disclosure is a significant thing to be kept in record. Moreover, he told that unexpectedly they have maps of Mars that have 100 to 10,000 times more resolution than maps of the deep ocean.
His opinion depicts that the deep ocean is a whole planet that we have just began to enquire into.
To design the new map, the researchers make use of database assembled by two satellite observatories: the European Space Agency’s CryoSat-2, and the Jason-1, operated by NASA and the French space agency CNES.
Both shuttles have apparatuses that can measure the topography of the ocean surface within a fraction of an inch. Measuring the surface of oceanic waters gives a good idea about the structures at its bottom resulting in discovery of the hidden mountains and volcanoes in the water floor; as the structures affect the height of the water at surface.
In response to a question raised on discovery of ocean bottom Sandwell replied that in our life times may be we are unable to see the ocean floor. However it’s not possible that we will be deprived of the underwater sight but the process is not cost and time effective So for the current time, scientists are making use of this map to reveal the veiled features under sea . The resolution is not so good but it is surely better than the previous one.
