"The original version of Google Ocean was a newly developed prototype map that had high resolution but also contained thousands of blunders related to the original archived ship data," said David Sandwell, a Scripps geophysicist.

I wonder what undiscovered relic we will find in the lines next since this is the latest images of the ocean bottom.

Through several rounds of upgrades, Google Earth now has 15 percent of the seafloor image derived from shipboard soundings at 1-kilometer resolution. Previous versions only derived about 10 percent of their data from ship soundings and the rest from depths predicted by Sandwell and NOAA researcher Walter Smith using satellite gravity measurements.
