What is "simonszand"

Simonszand is a sandbank between the West Frisian Islands of Schiermonnikoog and Rottumerplaat in the Netherlands. It is located in the municipality of Eemsmond in the province of Groningen.

The sandbank was originally mapped as being an Intertidal zone in approximately 1811, but changed in later mappings to be shown as a Supratidal zone after it became larger and migrated seaward.
