Macroalgal nitrogen isotope analysis (δ N) is a reliable method for the identification of nitrogen pollutant sources. Understanding δ N geospatial variation within small bays and/or harbour environments can help identify point sources of nitrogen pol...

A macroalgae (seaweed) herbarium nitrogen isotope (δ15N) record is produced for the River Mersey and Liverpool South Docks (England) between 1821 and 2018. A modern macroalgae δ15N record was also produced from September 2022. The herbaria δ15N recor...
