Distribution and palaeoecological indicator value of diatoms in Holocene coastal deposits of the southern North Sea (Lower Saxony, Germany)

Frank Watermann, Holger Freund & Gisela Gerdes
The development of the North Sea coastal landscapes during the past 8000 years has been strongly influenced by sea-level fluctuations that involved cyclical transgression, stagnation and even regression phases. Transgressive phases are reflected in NW Germany by Holocene coastal deposits consisting mainly of sand, silt and clay, whereas phases of regressive coastal development are indicated by the presence of peat layers. Although the East Friesian barrier islands in their present state are not older than...
