"Arctic sea level has been falling by a little
over 2mm a year - a movement that sets the region
against the global trend of rising waters.
A Dutch-UK team made the discovery after
analysing radar altimetry data gathered by
Europe's ERS-2 satellite.
It is well known that the world's oceans
do not share a uniform height; but even so,
the scientists are somewhat puzzled by their results.
Global sea level is expected to keep on
climbing as the Earth's climate warms.
To find the Arctic out of step, even temporarily,
emphasises the great need for more
research in the region, the team says."
