article_snippet.sent: So a French team studied the movement of ocean waves at the bottom of the seabed.
article_snippet.sent: A team of Japanese and Californian seismologists proposed that as ocean waves move in opposite directions and collide A team of Japanese and Californian seismologists create microseismic activity.
article_snippet.sent: But Fabrice Ardhuin, a senior research scientist at Centre National de la Recherche Scientifique in France, and a French team wanted to put this theory to the test.
article_snippet.sent: Fabrice Ardhuin, a senior research scientist at Centre National de la Recherche Scientifique in France, and his team began by studying and measuring seismic activity across the globe, including earthquakes, storms and the movement of ocean waves, throughout 2008.
article_snippet.sent: the researchers could then look at the reasons why. '
article_snippet.sent: Motions in all three bands are recorded everywhere on the planet and the team said the team can provide information on both the solid Earth structure, the ocean wave climate over the past century, and the properties of short period ocean waves. '
article_snippet.sent: Yet, the use of seismic data is limited because where and how ocean waves rock Earth is not known, in particular for the hum,' continued the team. '
article_snippet.sent: the team then studied ocean waves at the bottom of the seabed.
article_snippet.sent: So the team studied the movement of ocean waves at the bottom of the seabedthe seabed.
article_snippet.sent: The findings are published  in Geophysical Research Letters, a journal of the American Geophysical Union (AGU).
article_snippet.sent: Mr Ardhuin said that by measuring and understanding long, microseismic waves, researchers can learn more about how Earth is structured. '
