Gulf of California The Gulf of California (also known as the Sea of Cortez, Sea of Cortés or Vermilion Sea; locally known in the Spanish language as Mar de Cortés or Mar Bermejo or Golfo de California) is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately 4000 km . Rivers which flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The gulf's surface area is about 160000 km2 .
East Frisian Islands The East Frisian Islands (German: "Ostfriesische Inseln", West Frisian: "Eastfryske eilannen") are a chain of islands in the North Sea, off the coast of East Frisia in Lower Saxony, Germany. The islands extend for some 90 km from west to east between the mouths of the Ems and Jade / Weser rivers and lie about 3.5 to 10 km offshore. Between the islands and the mainland are extensive mudflats, known locally as "Watten", which form part of the Wadden Sea. In front of the islands are Germany's territorial waters, which occupy a much larger area than the islands themselves. The islands, the surrounding mudflats and the territorial waters (The "Küstenmeer vor den ostfriesischen Inseln" nature reserve) form a close ecological relationship. The island group makes up about 5% of the Lower Saxony Wadden Sea National Park.
