Plastitar in the Mediterranean Sea: New records and the first geochemical characterization of these novel formations

A new geological formation consisting of plastic debris admixed to petroleum oil residue, termed “plastitar”, has been recently described in the Canary Islands. Here, we report its widespread occurrence across the Mediterranean coast and new insights into its biogeochemical composition. Specifically...
