Subset of zooplankton abundance and biomass time series from net hauls at site L4 off Plymouth, UK between 1988-2020.

Ongoing zooplankton research at the Plymouth Marine Laboratory has established a time series of zooplankton species since 1988 at L4, a coastal station off Plymouth, UK. Weekly samples are collected by vertical net hauls (WP2 net, mesh 200 µm; UNESCO 1968) from the sea floor (approximately 50 m) to the surface and stored in 4% buffered formalin. This data set represents a subset of taxa from L4 zooplankton time series 1988-2020 v25082021 doi: 10/gzh6. Abundance results presented are number m-3 mean values from two replicate hauls made on each sampling timepoint. Biomass results are µg C m-3. Please see file L4 Zooplankton biomass_method protocols v24112021 for more information on this. It is encouraged that users of the data maintain contact with originators of the dataset to prevent misuse or misunderstanding of the data provided due to the complex nature and temporal coverage of the data provided.
