Wind parks at sea offering a new home to lobsters?

The Land of Lower Saxony promotes a pilot project of researchers on Heligoland

The Land of Lower Saxony is promoting a pilot project on the settlement of the European lobster in the “Riffgat“ offshore windpark with just under EUR 700,000. Researchers of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, are now starting on the rearing of 3,000 lobsters which they will be releasing in 2014. They wish to investigate whether lobsters successfully settle between the wind turbines.

New structures are created on the bottom of the North Sea with the construction of the windpark. Sand and silt soils dominate the bed in the German Bight; wind turbines are offering other ecosystems a new settlement area in the form of so-called hard substrate. One example of a rocky bed dweller is the European lobster which hides in crevices during the day and becomes active at night. Researchers at the Biological Institute Heligoland, which belongs to the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research, wish to place lobsters in this newly created habitat.

The Land of Lower Saxony, represented by the NLWKN (Lower Saxony Institute for Water Management, Coastal Protection and Nature Conservation), is funding the three-year pilot project ”Lobster settlement in the Riffgat windpark“ with just under EUR 700,000. The money comes from the compensation payments under nature conservation law for the „Riffgat“ windpark. An agreement has been concluded between the NLWKN and the AWI to use this funding. The project is intended to investigate the basic possibility of and the conditions for and ecological consequences of a lobster settlement of this kind.

“Whilst the large number of windparks which will be developed in the German Bight in the next 15 years represent an encroachment on the ecosystem, they could also be combined with measures of ecological enhancement“, says Prof. Dr. Heinz-Dieter Franke, AWI biologist on Heligoland. The closure of the windparks to industrial fishing created an urgently needed area of protection and recuperation for fish and invertebrate sea bed fauna. The inhabitants of hard beds threatened with extinction could also be given additional habitat. This also applied to the population of the European lobster in the German Bight which is essentially restricted to the rocky area around the Island of Heligoland. “Despite protective measures. the lobster population has not recovered from a strong decline in the fifties and sixties to this very day “, explains Franke. A successful settlement of the animals in the rocky fields surrounding the individual windparks as scour protection could contribute to a long-term stabilisation of the population.

The work is being conducted in close cooperation with the operator Offshore-Windpark RIFFGAT GmbH & Co. KG, Oldenburg (a merger of the energy provider EWE and the ENOVA Group) and the project partners datadiving GmbH with the scientific diver Dr. Roland Krone. AWI scientist Dr. Isabel Schmalenbach will be rearing 3,000 animals in a station on Heligoland next year. Once the young lobsters have reached a length of around ten centimetres, the researcher, working together with divers from datadiving GmbH, will release them into the windpark. In the coming years Schmalenbach and Krone will be investigating the lobster settlement grounds and a reference area to determine how many of the young animals have become successfully established in the stony grounds, whether they remain here or seek out a crevice in a neighbouring area, how accompanying fauna (large crabs and fish) develop and whether wild lobsters migrate into the area. The project is based on the many years of experience with rearing and release programmes for young lobsters on Heligoland.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
