Tertius (sand bank)
Tertius or Tertiussand is a sandbank in the Heligoland Bay off the coast of Dithmarschen . It lies west of the Mittelplate , between Norder- and Süderpiep . Tertius used to be a high sand , but has often been flooded for decades and therefore has no vegetation. Like other high sands or flooded sandbanks, the area is not assigned to any municipality or district.
Tertius is located about 10 kilometers west of the seaside resort of Büsum in the Meldorfer Bay and, like the other unpaved islands, high sands and sandbanks on the west coast of Schleswig-Holstein, is subject to constant eastward migration. In the south is the island of Trischen , in the northeast of the high sand Blauort . Tertius and the plate (sandbank) Tertiussand surrounding it are surrounded by the tidal current Piep , which allows access to the port of Büsum and is divided here seaward into Norderpiep and Süderpiep.
In addition to seabirds, numerous seals rest on the sandbank, so excursions to Tertius are offered from Büsum. Entering the sandbank in the Schleswig-Holstein Wadden Sea National Park , which is not in protection zone I , is only possible under certain conditions. The only building on Tertius is a beacon that serves as an optical navigation mark .
