We used a comprehensive deployment grid that enabled the generation of isotopic seascapes isoseascapes describing the topography of N pollution in coastal waters and identifying N input hotspots and their pathways of dispersion at sea. The N values of U. lactuca increased during 48 h of exposure to the gulf waters, indicating anthropogenic N inputs from wastewater derived sources. Comparison of the isoseascapes between two years differing in terms of rainfall identified coastal and offshore areas that were vulnerable to freshwater transported nutrients, consistent with terrestrial hydromorphology and sea surface water circulation. Isoseacapes were robust enough to reduce deployment effort, representing a powerful tool for monitoring and management strategies and useful for Environmental Protection Agencies, the main target audience of applied ecological research. 126 Published version http //www.scopus.com/record/display.url eid=2 s2.0 85037337665 origin=inward space time monitoring 8 space_time_monitoring 2018.pdf Articolo in rivista Macmillan, 0025 326X Marine pollution bulletin.
