Abstract:
A recently encountered fossil oyster bed (Ostrea edulis) located in the sublittoral zone offshore the island of Helgoland (German Bight, Europe) was investigated. During a ship campaign in June 2019 onboard RV „Mya II“, the local extent and surface properties of the oyster bed were determined by submersible underwater drift video and grab sampling. The aim of this study was to facilitate the first description of a sublittoral oyster bed in the area and to understand its past ecological state and the reasons of its demise. Ostera edulis and associated habitats disappeared from the North Sea at the beginning of the last century and are a current focal point of restoration initiatives across Europe.
Oyster shells were collected from the grab samples, cataloged and systematically analyzed. The weight of the valves was determined on a laboratory scale in grams with a precision of two decimals. The length (mm), width (mm), and degree of infestation (%) by the boring sponge Cliona sp. were digitally determined for each valve on the base of photographic images in the open-source software ImageJ (https://imagej.nih.gov/ij/).
