Mesozooplankton abundance data gathered as part of an annual autumn pelagic
survey in the English Channel, Celtic Sea and Bristol Channel, running from
2012-2016. Samples were obtained using twin ringnet deployments and
subsequently processed back at the lab using ZooScan image analysis. Count
abundances from semi-automatic image classifications on Plankton Identifier
(and later, EcoTaxa) were then converted into abundances per m3 using
estimates of filtered volume from flowmeter readings. The current dataset
comprises mesozooplankton results from the POSEIDON survey series which ran
until 2016, although results have continued to be obtained as part of the
expanded PELTIC survey series, which has been ongoing since 2017.
