Description

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.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 29,075 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

The OTTERS Project aims to promote societal transformation for marine and freshwater stewardship through scaling up citizen science.The Iliad consortium will develop virtual representations of the sea that will integrate earth observing, modelling and digital infrastructures to provide predictions of future developments "at sea".

Title The OTTERS Project and the Iliad consortium.
Funding Meduzot received funding from the European Union’s Horizon 2020 and Horizon Europe Framework Programmes for Research and Innovation under grant agreements no. 101037643 (ILIAD) and 101094041 (OTTERS).

Sampling Methods

This is a Citizen Science initiative.

Study Extent The dataset covers 20 latitudinal zones along the Israeli coast, and five longitudinal zones (0-200m, 200-1000, 1000-10000, >10000) from the coastline. From the sandy beach upon which jellyfish are stranded, to the pelagic realm jellyfish inhabit in the Israeli Mediterranean.
