Research motor boats

Aade

The white wooden motorboat Aade built in 1974 is on the move exclusively in the waters all around the North Sea island Helgoland. It runs out every single day to take samples for the Helgoland Roads long time investigation. This data row delivers high resolution of chronological and spatial data – it exists since 1962 and grasps physical and biological factors.

Moreover, the crew of the Aade collects biological material for scientific experiments. For it the motor boat is equipped with a crane system, plankton nets and a water sampling module. The Aade is the biggest "Börteboot" of Helgoland – the wooden boats are typical for the North Sea island. They bring passengers of ferries and holiday ships to the island and they are used also as fishing boats. The Aade carries, by the way, the name of a bay before the Helgolander dune.

Diker

The research divers of the Biological institution of Helgoland set to sea primarily with the aluminium motor boat Diker. The nine-metre-long motor boat is altered especially for the needs of the research diver's group, this is also expressed in the name of the motor boat: Diker is Halunder (the dialect of Helgoland) and means diver. Up to six divers can carry out marine biological investigations with the Diker also beyond the labs, in the natural living space. On the trips with the Diker the research divers of the AWI install and maintain measuring instruments on the sea floor, collect from hand organisms, map the alga communities or take sediment samples with a tube.
