Sounds of a Solar Storm
High school students listening to audio tracks of NOAA satellite data have identified the sounds of solar storms buffeting Earth’s magnetic field. The results of a UK-led citizen science project suggest that the approach of converting physical data into sound signals could help NOAA and other scientists make sense of massive amounts of data from satellites and other instruments.

Measuring tsunami remnants half a world away
By the time the waves of the 2004 Sumatra tsunami swept half way across the globe and reached Drake Passage at the Southern tip of South America, they were just ripples.
But two pressure gauges deep below the surface of the passage reacted to those tiny remnants of the once-towering waves, giving scientists a fortuitous opportunity to study the long-distance behavior of a tsunami.

New eyes on the ocean
A global flotilla of diving robots have their eyes trained on the seas. An ocean monitoring program, called Argo, run by the National Oceanic and Atmospheric Association, has currently deployed 3,239 satellite-connected floats. These monitors are constantly diving, free floating and surfacing. They are the marine equivalent to weather stations on land, recording temperature, salinity, dissolved oxygen, and chlorophyll levels. Such information is then beamed in real-time to data centers in France and California. And a new breed of floats is about to do more.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
