NASA's IceBridge mission contributes to new map of Antarctica

(Phys.org) —A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data—known as ...

Bird-borne cameras reveal gannet habits

Images from cameras attached to the tails of gannets have revealed their appetite for fishing boat discards, soon to face a ban under reforms to the EU Common Fisheries Policy.

Low-energy GPS sensing looms large

Location sensing has become ubiquitous—it's present every time you turn on your smartphone or engage your car's navigation system. It's also become critical to a variety of outdoors and remote research applications, such ...

Galapagos tortoises are a migrating species

Rapid tsunami warning by means of GPS

For submarine earthquakes that can generate tsunamis, the warning time for nearby coastal areas is very short. Using high-precision analysis of GPS data from the Fukushima earthquake of 11 March 2011, scientists at the German ...

NASA tests GPS monitoring system for big U.S. quakes

(Phys.org) -- The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes ...

Recent Indonesia quake added pressure to key fault

(AP) -- Seismologists say last week's powerful earthquake off western Indonesia increased pressure on the source of the devastating 2004 tsunami: a fault that could unleash another monster wave sometime in the next few decades.

Scientists track motions of shifting plates using GPS sensors

The Pacific Northwest is a restless place. The ground is being shoved by tectonic plates. Snow-capped volcanoes inflate and deflate in concert with the creep of molten rock. Coastlines bulge as tension builds on an offshore ...
