Jadebusen
The district is located at the western banks of the River Weser between Bremen and the river's mouth. Several rivers cross the district from west to east, the largest of them being the Hunte, which runs through Oldenburg before entering Wesermarsch. In the north the Weser mouth and the Jade Bight (a bay off the North Sea) enclose the Butjadingen peninsula. Here the largest town of the district is located: Nordenham, lying opposite to Bremerhaven at the Weser mouth.
