Despite the efforts deployed to understand the GOMOS instrument anomaly, the investigation team does not yet fully comprehend the problem.

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.

Acquired from orbit 800 kilometres away, this Envisat image shows two volcanoes erupting simultaneously on Russia's snowy Kamchatka Peninsula this week.

Health of coral reefs detected from orbit

10 March 2005

Australian researchers have found Envisat's MERIS sensor can detect coral bleaching down to ten metres deep. This means Envisat could potentially monitor impacted coral reefs worldwide on a twice-weekly basis.

MERIS/AATSR Workshop looks at twin sensors with many uses

10 March 2005

Two satellite sensors work better than one for the study of Earth's oceans, atmosphere and land - that was the message of a major ESA workshop bringing together scientific users of Envisat's MERIS and AATSR instruments.

Satellites guide world's top yachts through Southern Ocean 'iceberg alley'

07 March 2005

Three of the world's largest and fastest yachts are in the midst of a non-stop trans-global race, hurtling in excess of 25 knots - 46 kilometres per hour - through the Southern Ocean encircling Antarctica. Iceberg collision is a real risk, but ice-sensitive radar satellites are monitoring the area to provide advance warning to crews.

Envisat detects 'grass of the sea' blooming early off Norway.

04 March 2005

Spring starts early this year in Norway's fjords and coastal waters, with sunny weather awakening a colourful bloom of marine phytoplankton. ESA's Envisat spacecraft is being used to monitor its development.
