title: Sightings of Physalia physalis on the coasts of the Gulf of Cadiz over 2009-2022 compiled by ICMAN (CSIC)

description: [Methods for processing the data] Records of Physalia physalis sightings are generated/obtained from various sources of information; individual informants who submit sightings electronically or verbally, press releases and notices from coastal monitoring stations.
description: [Description] This dataset provides measurements of Physalia physalis abundance on the coast of the Gulf of Cádiz conducted over 2009-2022, covering Spanish and Portuguese 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.
