Todd.The productive eastern boundary current (EBC) systems provide significant sources of global marine protein and have been subject to intense research over the last 50 years. Yet large jellyfish, which are present in all four major systems, have seldom been included in otherwise comprehensive reviews. This undoubtedly reflects their lack of intrinsic commercial value, and the consequently slow pace of knowledge generation. We attempt to redress that imbalance here and to consolidate disparate information on the macromedusae of EBC systems. With the exception of the Canary Current system, which supports a generally low biomass of mostly subtropical taxa, 372jellyfish assemblages in the Benguela, Humboldt and California Current systems are dominated by cool water taxa that can occur at high abundances. While there are large gaps in knowledge, which are highlighted, it is clear that jellyfish can play significant ecological roles in each system. Although there may be strong similarities in faunal composition among the different systems, there are pronounced differences in population responses to the environment and in system resilience and these are reviewed and discussed.Variously, we would also like to thank the Namibian government for access to data and to the National Research Foundation (South Africa), the Royal Society (London), the EAF Nansen Programme and the University of the Western Cape for financial support over the years. We are grateful to the Chilean government and the Agencia Nacional de Investigación y Desarrollo de Chile – formerly Comisión Nacional de Investigación Científica y Tecnológica, and IMARPE for their financial support, and would like to acknowledge grants awarded by the Inter-American Institute for Global Change Research in Montevideo (GEO-0452325, EXA 470/10, PIP 12-201101-00892; CRN3070), as well as the Ministerio de Ciencia, Tecnología e Innovación Productiva in Argentina (FONCyT 01553, FONCyT PICT 2006 No. 1553).

Jellyfish abundance on the shores in the Canary Current Large Ecosystem over 2009-2019 compiled by ICMAN (CSIC) and INRH

The database provides measurements of jellyfish species and abundance on the shores of the whole Canary Current Large Ecosystem conducted over 2009-2019, covering Spanish and Moroccan coasts. The dataset is provided as [space] delimitated plain text file within a compressed folder that also includes a single README file (in text format) containing a detailed description of the data structure.[General Notes] The data are provided under an Attribution-ShareAlike 4.0 International license. However, if you use the data, so as to support the authors, please consider citing the above mentioned article where data collection and analytical techniques are given in detail. Here we only give a brief details and a guide to the contents of the data files. Data files are in UTF8 encoding, plain text format with comma used as the delimiter. All data files have column titles as the first line. One column is written for each measured parameter. Missing data are filled with NaN.[Geographical coordinates of the sampling area] coordinates.txt provides the geographical coordinates of the sampling area. ST.ID represents the code (used to link to other data tables) for each site. long and lat are longitude and latitude, respectively.The dataset is subject to a Creative Commons License Attribution-ShareAlike 4.0 International.This data set includes data collected from ICMAN-CSIC (Spain) and INRH (Morocco) between 2009 and 2019 that have been used to estimate the diversity, seasonality and inter-annual variability of jellyfish abundance in the Canary Current Large Ecosystem.This research was supported by projects P07-RNM-02976 (Junta de Andalucía), CTM2011-22856 (Spanish Ministry of Science and Innovation) and 2019AEP203 (CSIC).Peer reviewe
