Kriegers Flak

Location A, southeast of Kriegers Flak—a shoal of less than 20 m depth north of Riigen—is the northernmost position of a section of four ADCP moorings aligned between the Kriegers Flak and Hiddensee, a small island east off immediately Riigen (see A-D in Fig. 6.1). The section represents simultaneous current measurements of about 215 days with one interim replacement of the ADCPs on 27 July that lasted only a few hours. 

At Kriegers Flak in the open Arkona Sea, the weak mean speeds and the small stability factors are caused by alternations of the current regime during the 7 months observation period. Compared to sites B, C, and D further south, in agnitudes are weak owing to the nearby shoal of Kriegers Flak, which hinders the free propagation of the currents.
