Since 70% of the earth's surface is covered by oceans, perhaps large meteors hit the earth alot more often that we realize. /Ira Post Extras:       Ebyl member Reged: 07/04/12 Re: If a meteor falls in the ocean?

It's global for the megaton range. When at least two sensors are able to detect it, they can calculate the location. Edit - Sorry, meant to add that it would really depend on what kind of coverage they've got for infrasound detectors. IMS has a bunch of stations around the world, and there are of course others. Here is the IMS map (I think). http://www.bgr.bund.de/EN/Themen/Seismologie/Bilder/ims_infra_g.png?__blob=no... And of course there are other ways to detect the meteors.

[Re: wirenut]       #5691063 - 02/20/13 02:50 PM Edit   Reply   Quote Quick Reply   I guess one *could* theoretically retrieve fallen meteorites from the ocean bottom. One could accurately track and plot the impact locations, and get to the site quickly. Then, locate the meteorites using some kind of high-powered, underwater metal-detector, bottom-mapping sonar, etc. The problem then becomes retrieving the meteorite from the bottom (possibly miles down) and transporting it to the surface. And therein lies the devil in this scenario. While accomplishing this feat would not be impossible with current technologies and engineering, it would be cost-prohibitive. It is far cheaper to retrieve them from dry land as they fall, and they are less altered/damaged than a meteorite recovered from a body of water.
