Human-induced desalinization of Manzala lagoon, Nile delta, Egypt: Evidence from isotopic analysis of benthic invertebrates

This study combines isotopic (⁸⁷Sr/⁸⁶Sr, δ¹⁸O and δ¹³C) with paleontological data to derive a paleosalinity proxy in order to determine the impact of the Aswan High Dam on Manzala lagoon in Egypt's Nile delta. Analyses were made on 17 invertebrate taxa (molluscs, crustaceans, foraminifera, serpulid worms). These were collected in 17 surficial samples and 18 samples from two cores collected at the two salinity extremes of the lagoon. Of the …
