Envisat enables first global check of regional methane emissions

18 March 2005

The SCIAMACHY sensor aboard Envisat has performed the first space-based measurements of the global distribution of near-surface methane, one of the most important greenhouse gases. As reported in Thursday's issue of Science Express, the results show larger than expected emissions across tropical land regions.

Giant iceberg B-15A edges past floating ice pier

18 March 2005

Envisat radar imagery confirms that the B-15A iceberg ? the world's largest floating object ? is adrift once more after two months aground on a shallow seamount. This latest development poses a renewed threat to the nearby pier of land-attached ice known as the Drygalski ice tongue.
