The research site is the Sueste Environmental System (4°S\/32°W), located in the Mar de Fora, on the southern coast of the Fernando de Noronha Archipelago, in the south-equatorial Atlantic. The seasonal study conducted quarterly in 2010-11 indicated a textural and compositional homogeneity of the sediments, in general, moderately selected bioclastic fine sands, composed of mollusc\/coral fragments and with low organic content (C \u0026lt; 2.0%\/ N \u0026lt; 0.2%) of marine origin (C\/N \u0026lt; 12.0 and d13C \u0026gt; -19.0¿PDB). Although seasonal morphology and geochemistry indicated spatial and temporal differences between sediments in the western and eastern portions of Sueste Beach, as well as in each sedimentary subenvironment studied: bay, beach, dune, lagoon, and mangrove. Finally, the beach profiles reveal a seasonal pattern of erosion and deposition due to regional oceanographic-climatic conditions and local morphodynamic factors. These transects also indicate the ongoing silting process in the Sueste mangrove and lagoon.","brand":"Our Knowledge Publishing","offers":[{"title":"Default Title","offer_id":53820841099606,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9786209571985_1_53c2f8a6-ea5b-44a1-8af2-ceddbc7a4827.jpg?v=1783430687","url":"https:\/\/www.momoxbooks.com\/products\/lins-medeiros-sayonara-sedimentation-and-coastal-geochemistry-on-a-brazilian-oceanic-island-9786209571985","provider":"momoxbooks","version":"1.0","type":"link"}
