Plankton abundance measured by flow cytometry from long term time series at Station E1 in the Western English Channel from 2014 to 2016.

This dataset contains depth profiles of the abundance of groups of plankton as cells per millilitre, measured using flow cytometry from the long-term sampling station, E1 (50 2.05'N; 4 22.5'W) situated off the south-west coast of England, United Kingdom, from 2014 to 2016. The groups quantified are divided into phytoplankton and heterotrophs. Phytoplankton groups quantified are: Synechococcus sp. (cyanobacteria)(Syn), picoeuakryotes (smaller than 2 µm) (Peuk), cryptophytes (Crypto), coccolithophores (Cocco), small dinoflagellates (<20 µm) (Dino), Phaeocystis sp. (Pcystis) and nanoeukaryotes (Neuk) not already mentioned (2-20 µm). Heterotrophs quantified are: bacteria with relatively high nucleic acid content (HNA) and bacteria with relatively low DNA. Samples were collected and analysed from 2, 10, 20, 30, 40 and 60 m depths.
