Abstract:

Overview of higher meiofauna taxa and total counts from samples (0-5 cm) collected during a dredge-experiment in the German License Area (BGR-area) in the Clarion Clipperton Zone on board of the German vessel SONNE during the SO268 expedition in 2019. Samples are categorized per impact type: pre-impact, post-impact (track, thick sediment cover and thin sediment cover).
