Jellyfish observations (Citizen Science Data) are collected from the Israeli Mediterranean coast and sea since June 2011 via a webapp (www.meduzot.co.il). 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.
