Observations are validated by experts in a two-tier process, once daily and again semi-annually. This data is used to alert the public to incoming swarms and helps us increase our knowledge of their behavior, ecology, phenology (e.g. Edelist et al. 2022; Levy et al. 2024), and taxonomy (Edelist et al. 2019). The project also educates and disseminates information about jellyfish sting prevention and treatment (Edelist et al. 2023). This data is also stored in the EU Iliad Project Ocean Information Model.OccurrenceCitizen SciencejellyfishIsraeli coast <http://www.opengis.net/def/crs/OGC/1.3/CRS84> Polygon((34.585 29.286, 34.585 33.321, 35.31 33.321, 35.31 29.286, 34.585 29.286)) University of Haifa, Ruppin Academic CenterENGLISH
