Found on Google Earth: Atlantis (no) and pink bunny (yes)

The release of Google Earth 5.0 included better bathymetry of much of the ocean floor. (Bathymetry is the study of ocean and lake depth)

Some have claimed that this pattern on the Atlantic sea floor west of the Canary Islands is the ruins of the mythical island of Atlantis. The area is over 100 miles across, and the lines would represent roads or something.

My response: baloney. The lines are artifacts of the processing of digital sonar data collected by a ship that surveyed the area by making a grid-like pattern. The Google bathymetry data has various processing artifacts just about anywhere you look; this is just a little more obvious.

Not that interesting things aren’t found from time to time on Google Earth. Here’s one of my favorites: the Giant Pink Bunny of Artesina, Italy:

Google Earth – improved ocean floor

The ocean floor on Google Earth has always been a little fuzzy, but the good folks at Google have recently improved the resolution:

Gulf of Mexico. The irregular surface is formed by the rising of salt to form salt domes in some places, and dissolution of salt in others. The escarpment at the southern end of the chaotic area marks a thrust fault.
Gulf of Mexico south of Louisiana. The irregular surface is formed by the rising of salt to form salt domes in some places, and dissolution of salt to form pits in others. The escarpment at the southern end of the chaotic area marks a thrust fault.

These worm-like ridges are off of the Oregon coast, and are being formed by the crumpling of sedimentary material as the oceanic Juan de Fuca plate (to the left) subducts beneath the continental North American plate (to the right). Note also the submarine canyon cutting into the continental slope at the top.

Techie terrorists

TimesOnline article: Google Earth accused of aiding terrorists.

Apparently the Mumbai terrorists used Google Earth as part of planning their attack.

An Indian Court has been called to ban Google Earth amid suggestions the online satellite imaging was used to help plan the terror attacks that killed more than 170 people in Mumbai last month.

A petition entered at the Bombay High Court alleges that the Google Earth service, “aids terrorists in plotting attacks”. Advocate Amit Karkhanis has urged the court to direct Google to blur images of sensitive areas in the country until the case is decided.

Google Earth is a wonderful tool for studying Earth, whether for natural or manmade features. A few places in the world are intentionally blurred on Google Earth, but there are many sensitive military, industrial, and government locations that are viewable in great detail. Living in a world of sin where people will twist what is good and use it for evil, what restrictions should there be on public availability of imagery?
