Chlorophyll-a concentrations in marine sediments from experiments and Fehmarn Belt (2020-2021): [research data] Forster, Stefan (VerfasserIn) Powilleit, Martin , 1959- (VerfasserIn) Pülm, Laura (VerfasserIn) Lemke, Josephin (VerfasserIn) Runkel, Claudia (VerfasserIn) Computerdaten Forschungsdaten 2024 2024 eng electronicelectronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource During an investigation on the effects that bottom-trawling, we found that otter boards that keep the nets open, bury surface sediment at a few centimeters sediment depth. This is also done by animals living in the sediment and the process is considered very important for sediment ecosystem integrity. We try to differentiate between the two and estimate that natural bioturbation is much more likely than otter board sediment reversal in OUR sediment areas.
