Marine researchers are preparing to use a Zeppelin off the coast of northern Germany to collect data on whirlpools, according to the Helmholtz research centre.
In June, an airship fitted with high-resolution cameras is to track smaller and more unstable whirlpools as it flies over the Baltic Sea, north-east of Germany.
The research team aims to use the data to analyse the influence of whirlpools on ocean circulation and on the food chain, head of the Institute for Coastal Research at the Helmholtz research centre, Burkard Baschek, said.
"Just like the cogs in a clock, whirlpools in the sea are all interlinked," Baschek said.
The airship is due to be launched from the island of Usedom on June 18.
