Meso and macrozooplankton abundance in the Bristol Channel, Celtic Sea and English Channel 2017-2023 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS0fd3bb0e-876c-4ab9-81dd-ee0afeb10ada Mesozooplankton (down to ~300µm size) and macrozooplankton abundance data gathered as part of an ongoing annual autumn pelagic survey in the English Channel, Celtic Sea and Bristol Channel, with data currently available from 2017-2022. Samples were obtained using twin ringnet deployments at set stations and subsequently processed back at the lab using ZooScan image analysis. Count abundances from semi-automatic image classifications on EcoTaxa are then converted into abundances per m3 using estimates of filtered volume from flowmeter readings. The current dataset comprises zooplankton results specifically from the PELTIC (Integrated Pelagic ecosystem survey in the Western Channel and Celtic Sea) survey series, which has expanded the collection of pelagic data from the core regions sampled in the POSEIDON survey series which ran between 2012-2016. 20220825 20220803
