Satellitenbildkarte \"Nordfriesische Inseln\"
This is a wonderful and fascinating image detail, with Sylt, Amrum, Foehr, the Halligen, Sankt Peter Ording, Heligoland and the mouth of the Elbe with Cuxhaven.
Because of low tide, the mudflats are visible.
The varying presentations of water result from an interplay of sediments, groundswell, wind fields, and currents. Numerous ships are recognisable.
Lush grass meadows and pasturage dominate the land areas.
The border to Denmark stands out clearly through the abrupt increase in land cultivation.
Larger cities contained in this image detail are Cuxhaven, Husum, Heide, Brunsbüttel, and Westerland.

An area of 108 x 144 Km is reproduced here in a picture measuring 60 x 80 cm. That is a scale of 1: 180 000.

Interesting Facts about the Wadden Sea

The WaddenSea area of the North Sea is typified by extensive tidal mud flats. An area of about 9000 square kilometres, 450km in length and up to 40 km in breadth, this region lies between Blavandshuk, Denmark in the north east and Den Helder, Holland in the south west.
This makes it the most extensive mud flat area on earth.
Whereby, in our satellite picture only the North Frisian part can be seen.
The ground of the North Sea which is revealed at low tide is known as tidal mud flats.
It is flooded twice a day at high tide and falls dry again at low tide, whereby the water often flows off through deep tidal water channels.

The WaddenSea developed about 7,500 years ago and it has one of the highest primary production rates in the world, and consequently serves a myriad of birds and fish as both resting place and source of food.
Almost the entire WaddenSea is protected.
The German part is a National Park, except for the bigger estuaries which are important shipping lanes. The Danish part is to follow suit in 2009, the Dutch part is subject to a complex network of different protection measures.
The WaddenSea regions of Schleswig-Holstein, Lower Saxony, and the Netherlands have applied for World Natural Heritage status.
