Are ocean waves in the North Sea becoming more severe?

Index of severe sea state events in the German Bight. The index has been derived from data obtained from a numerical reconstruction of past sea state conditions 1958-2002

Waves at the sea surface (sea state) are a phenomenon closely related to near-surface winds. Simplified, stronger winds generate higher waves and more severe hazards for the coasts and shipping. At the Institute for Coastal Research scientists investigated whether or not sea states in the North Sea have become more severe in the recent past. Their results have recently been published in the international journal Ocean Dynamics.

PRESTIGE disaster could have been reduced

Prestige

In November-13, 2002, the disabled tanker PRESTIGE was drifting towards the Galician coast. The initial response of the Spanish authorities seemed to be clear when the tanker was dragged off-shore in the North-Western direction. However, several changes in the drag direction made in the aftermath along with waves caused more stress to the ship. A few days later the PRESTIGE finally sank off the Northwestern Atlantic coast of Spain releasing about 30.000 tons of heavy fuel oil. This spill then provoked disastrous consequences along the Spanish and, later, the French coasts. Images of oiled shores and animals as well as jobless fishermen had been made public by the media and triggered a long-lasting discussion about the transparency and rationale of the decision made by the authorities (Serret et al., 2003; Freire et al., 2006). In recent published studies, scientists of the GKSS and the Institute for Biology and Chemistry of the marine Environment (ICBM) at the University of Oldenburg found that oil spill contingency management could have taken a significant benefit from scientific support. The main research question was: Could scientific information and tools available at the time of the emergency be of support in order to minimize the risk for regional ecosystems and economies?

2006-12-04 dumped material at the Baltic coast

Long-term development of dumped material at the German Baltic coast

Harbours and shipping channels all over the world have to be dredged to remain navigable. Periodical maintenance is necessary, but dredging and dumping activity releases often highly polluted sediments into the coastal waters. The fate of dredged material dumped close to the Baltic coast was followed over more than three years by means of multibeam technology. Volume estimations revealed that the disposed material was transported away only during the dumping phase. Over the following years merely reworking of the material took place resulting in the smoothing of the surfaces. This process was fastest at the smallest horizontal scales. It was estimated that these structures as a whole would persist for about a century.

Oil-sensitivity index for the Wadden Sea

Wattvogel

At the Institut for Coastal Research an automated expert model was created last year, which now is an important decision guidance for the "Havariekommando" in precautional planning. The "Havariekommando" - an organisation of the Germen Federal Government and coastal Federal States - is responsible for combat to oil pollution.
