The Ocean Equity Index is a scorecard that anyone can use to assess the extent to which ocean projects and policies recognize relevant stakeholders, include them in decision-making and otherwise treat them fairly.

Hearing tests conducted across kilometres of ocean off the Australian coast show humpback whales react to higher frequency sounds than expected.

A scientific study conducted as part of the MarPITIUS25 project of the IbizaPreservation Chair in Blue Criminology at the Universitat Jaume I warns that Ibiza’s coastline is in a compromised ecological condition, even in areas where Posidonia oceanica seagrass meadows remain structurally well preserved. The results of the visual fish census, carried out by researchers from the University of Alicante and Universitat Jaume I, reveal communities dominated by small and juvenile fish, with a low presence of adult individuals and overall low biomass.

The study includes a direct comparison with equivalent censuses conducted in Dénia using the same methodology. In this case, the findings show greater biodiversity, a higher number of commercial species, a more balanced size structure and significantly higher biomass than that recorded along the Ibizan coast.

Fieldwork was conducted in June 2025 in three representative areas of Ibiza’s coastline — Santa Eulària, Cala Sol d’en Serra and Talamanca — coinciding with a period of peak tourist and environmental pressure. A total of 3,243 individuals belonging to 15 species were recorded, a low figure for this type of habitat, particularly when compared with other areas of the western Mediterranean, according to the University of Alicante and the Universitat Jaume I.
