Although general trends in transgressive to highstand sedimentary evolution of river-mouth coastlines are well-known, the details of the turnaround from retrogradational (typically estuarine) to aggradational-progradational (typically coastal/deltaic) stacking patterns are not fully resolved. This paper examines the middle to late Holocene eustatic highstand succession of the Po Delta: its stratigraphic architecture records a complex pattern of delta outbuilding and coastal progradation that followed eustatic stabilization, since around 7Á7 cal kyr BP. Sedimentological, palaeoecological (benthic foraminifera, ostracods and molluscs) and compositional criteria were used to characterize depositional conditions and sediment-dispersal pathways within a radiocarbon-dated chronological framework. A three-stage progradation history was reconstructed. First, as soon as eustasy stabilized (7Á7 to 7Á0 cal kyr BP), rapid bay-head delta progradation (ca 5 m year À1 ), fed mostly by the Po River, took place in a mixed, freshwater and brackish estuarine environment. Second, a dominantly aggradational parasequence set of beachbarrier deposits in the lower highstand systems tract (7Á0 to 2Á0 cal kyr BP) records the development of a shallow, wave-dominated coastal system fed alongshore, with elongated, modestly crescent beaches (ca 2Á5 m year À1 ). Third, in the last 2000 years, the development of faster accreting and more rapidly prograding (up to ca 15 m year À1 ) Po delta lobes occurred into 30 m deep waters (upper highstand systems tract). This study documents the close correspondence of sediment character with stratal distribution patterns within the highstand systems tract. Remarkable changes in sediment characteristics, palaeoenvironments and direction of sediment transport occur across a surface named the 'A-P surface'. This surface demarcates a major shift from dominantly aggradational (lower highstand systems tract) to fully progradational (upper highstand systems tract) parasequence stacking. In the Po system, this surface also reflects evolution from a wave-dominated to 3029 river-dominated deltaic system. Identifying the A-P surface through detailed palaeoecological and compositional data can help guide interpretation of highstand systems tracts in the rock record, especially where facies assemblages and their characteristic geometries are difficult to discern from physical sedimentary structures alone.

“…Nevertheless, species characterizing a low food environment like G. charoides and G. orbicularis are more abundant in eastern part than the western. The shelf assemblage is more diverse and consists mainly of Ammonia beccarii, Elphidium lidoense, Elphidium granosum, Textularia pseudogramen, Textularia sagittula, Bolivina spathulata, Bolivina dilatata, Cassidulina crassa, Cassidulina levigata/ carinata, Haplophragmoides membranaceum, Gavelinopsis praegeri, Bigenerina nodosaria, Trifarina angulosa and Bulimina marginata Mojtahid et al, 2009;Milker and Schmiedl, 2012).…”

Foraminifera and ostracods have been quantitatively studied in core MD01-2472, from the upper continental\ud slope (at water depth of 501 m), to evaluate their relationship with bottom water condition\ud variability and decipher the control of the Levantine IntermediateWater (LIW) current on benthic faunas.\ud The occurrence of reworked ostracod species (originating from the continental shelf) and, the presence of\ud shallow water Elphidium/Ammonia benthic foraminifera are used to estimate the degree of along-slope\ud transport at the core site. This has revealed two intervals of along-slope transport also associated with\ud coarse-grained contourite deposits, deposited during the YD and HS2 episodes. Planktonic-benthic\ud foraminiferal and ostracod assemblages reflect climate oscillations. Peaks of the polar planktonic Neogloboquadrina\ud pachyderma (left-coiling S) may be used to identify Heinrich Events. Interstadials are\ud marked by abundant ostracod species such as Paracypris sp., Argilloecia acuminata, and Cytheropteron\ud alatum and the presence of benthic foraminifera like Bulimina marginata, Bulimina costata and Gyroidina\ud altiformis. The BeA and Holocene are characterized by abundant warm water species of planktonic\ud foraminifera and by the ostracod species Polycope sp. We hypothesize that there is relationship between\ud LIW intensification during cold rapid climate events and benthic fauna assemblage variations due to\ud changes in: 1) bottom water ventilation; and 2) the export of nutrients and/or sediment particles by\ud bottom currents

“…Benthic foraminifera and ostracod assemblages, which have a high sensitivity to environmental change, were analyzed both qualitatively and quantitatively (Aiello, Barra, De Pippo, Donadio, & Petrosino, ; Aiello, Barra, De Pippo, & Donadio, ; D'Amico et al, ; Stamatopoulos et al ; Balassone et al, ; Mangoni et al, ; Marino et al ). Benthic foraminifera and ostracod taxa were collected from sediment samples washed through a 125 µm sieve and identified according to the modern and classic literature, with a specific focus on the Mediterranean area (Müller, ; Barbeito‐Gonzalez, ; Bonaduce, Ciampo, & Masoli, ; Breman, ; Sen Gupta, Smith, & Machain‐Castillo, ; Aiello & Barra, ; Debenay, ; Milker & Schmiedl, ; Aiello, Barra, & Parisi, ; Aiello, Barra, Parisi, Isaia, & Marturano, ). A total of 42 benthic foraminiferal and 59 ostracod species were identified and the studied specimens are now housed in the Aiello Barra Micropaleontological Collection (A.B.M.P.)…”

Holocene paleogeographic evolution of an ancient port city of the central Mediterranean area: Natural and anthropogenic modifications from Salerno city, southern Italy

et al. 2019

A multidiplisciplinary study, including geomorphological, lithostratigraphical, geochronological, geochemical, and paleontological investigations, was carried out in the coastal area of Salerno city, southern Italy. The study aimed to outline the Late Glacial‐Holocene geoenvironmental evolution of Salerno's port area in response to both natural and anthropogenic factors. The geomorphological study included an examination of historic maps, which enabled a detailed reconstruction of the coastal landscape change during historic times. Lithostratigraphical analyses of three new boreholes, supported by radiocarbon and tephrochronological data, and of previously retrieved core‐successions and archaeological trenches, extends our reconstruction of the paleogeographical evolution of the Salerno coastal area back to the Late Pleistocene. Geochemical and paleontological analyses of samples from the newly acquired cores were combined with the lithofacies analyses of previously retrieved cores to detect ancient harbors in the area of the current port facilities of the city and surrounding urban areas. This work contributes to scientific debate about the specific sedimentary architectures and geochemical properties of the Salerno harbor environment and refines methodological approaches for characterizing and assessing the evolution and demise of ancient port facilities in Mediterranean coastal cities.
