In August this year they counted only 17 Knots on the islet Griend in the Wadden Sea whereas they usually count 30,000 to 40,000 Knots. Knots breed in Greenland and North-Canada and winter around the North Sea. The scientists consider there is only a small possibility that the Knots have colonised a new territory. According to them, the decrease is caused by changes in the bottom of the Wadden Sea, which are brought about by the cockle and mussel fishery. The bottom is getting less silty and more sandy and Knots eat small shellfish (Macoma baltica and juvenile Common cockle) that live in silt. In October 2002 the shellfish industry got a permit from the Dutch government to fish in the protected zones in the Wadden Sea. Because of the objections of Nature organisations the permit was temporarily withdrawn. The nature organisations stressed the risks of the fishery for birds like Knot, Oystercatcher and Common Eider. They claim that these birds and the shellfish industry are direct competitors, while the fishers deny this and claim Knots don't eat cockles. They started a lawsuit against the withdrawal of their permit, which they won on 6 December 2002. Accelerated sea level rise expected due to Arctic ice melt The floating sea ice cover of the Arctic Ocean shrank to
record levels in the late summer of 2002, according to a new study by
University of Colorado scientists. This continues a trend of increasing
sea ice losses over the past two decades, possibly longer. With other
evidence pointing to changes in atmosphere and ocean circulation, positive
temperature trends, snow cover reductions, and permafrost warming, the
sea ice conditions in 2002 raise further concern that climate change is
significantly altering the Arctic, and that human activities may be partly
to blame. The total area of surface melt on the Greenland Ice Sheet for
2002 also broke all known records for the island. The scientists estimate
that a change in the Greenland climate toward warmer conditions would
lead to an increase in the rate of sea-level rise mainly due to the dynamic
response of the large ice sheet and not so much to the surface melting.
For every degree (F) increase in the mean annual temperature near Greenland,
the rate of sea level rise would increase by about 10 percent. Currently
the oceans are rising by a little more than half an inch per decade. In
addition, melt water has been shown to directly affect the rate of ice
flow off Greenland, penetrating the ice sheet and causing the glaciers
to accelerate in speed as they slide over a thin film of melt water. Excessive
melting of sea ice, along with runoff from the Greenland Ice Sheet, also
has the potential to "cap" deep water convection in the North Atlantic.
This could profoundly impact global ocean circulation and climate. In
other studies, changes in the North Atlantic circulation have been implicated
in starting and stopping Northern Hemisphere ice ages. Europe takes measures to prevent further oil tanker accidents On 3 December 2002, the European Commission published a
blacklist of ships that could be banned from European waters and urged
the European Union to prohibit the transport of heavy fuel in single-hulled
tankers. This was a reaction on last month's oil spill off the coast of
Spain. The Commission called on EU heads of state and government to rule
on the measure at a summit this week in Copenhagen. In the European Council
of Ministers of Transport, on 6 December, the Netherlands slowed down
these measures. Earlier, on 5 November 2002 the European Parliament and
the Council of the European Union adopted a directive that amends the
previous directives on maritime safety, prevention of pollution from ships
and shipboard living and working conditions. With the aim of improving
the implementation of Community legislation on these subjects, this Directive
makes a reference to the Committee on Safe Seas and the prevention of
Pollution from Ships (COSS). With the same aim, it accelerates the update
and facilitates the amendment of such legislation in the light of developments
in the international instruments applicable in the field of these subjects,
pursuant to Regulation (EC) No 2099/2002. Member States shall implement
the Directive no later than 23 November 2003. Deadline for submitting contributions to Coastal Guide News No 25, 2002: 17 December 2002 (will be disseminated on 20 December 2002)
