New Light on Ice Motion (DAAC Study)
Rachel Hauser November 5, 2001 Detailed antarctic temperature and climate records date only from the late 1950s, with limited information dating from the turn of the 20th century. Now, using visible and near-infrared satellite imagery, scientists have piec...
Observing Volcanoes, Satellite Thinks for Itself

Sensing Remote Volcanoes (DAAC Study)
Belinda’s eruption might not have been detected for weeks or even months. “Normally, this remote volcano would have gone unmonitored,” said Rob Wright, research scientist at the Hawaii Institute of Geophysics and Planetology (HIGP). “However, when our sys...
