“…However, understanding how past humans interrelate to the environment further temporal comparisons between climatic, environmental and archaeological archives need to be implemented, by accessing the cascading set of socio-ecosystem responses from the global to the local scale. Following the end of the Last Glaciation, the coastal configuration profoundly changed resulting in the global sea-level rise flooding of the Late Pleistocene littoral plains (Shennan et al, 2000;Jakobsson et al, 2017). Sea-level rise was translated into the loss of human settlement areas, reduction of hunting territories, and modification of coastal ecosystems.…”

Consecutively to the global sea-level rise, coastal landscapes significantly changed during the Early Holocene. We explored how coastal mutations have affected ancient human systems in the western Mediterranean. The Pego-Oliva basin (Spain) provides a thick sediment sequence located in proximity to two well-studied Mesolithic and Neolithic archaeological sites. Based on 16 sediment cores, sedimentological analyses, 14 C dates, and integration of previous works, we reconstructed the architecture of the sedimentary facies and the chronology of deposition for the last 9500 years. From 9500 to 8200 cal. BP, the stepwise inland migration of the coastline is characterised by the deposition of peat layers at distinct depths indicating four phases of barrier-lagoon systems development. The marine transgression caused the disappearance of the lagoon at 8200 cal. BP, and reached a maximum inland position at 7300 cal. BP. Since 5800 cal. BP, sea-level stabilisation induced coastal progradation and barrier-lagoon system construction. Five marine flooding phases dated at 9500, 9100-9000, 8750-8650, 8450-8200, and 8100-7300 cal. BP match Atlantic meltwater pulses. Comparison to archaeology shows that the long-lasting Mesolithic occupation corresponds to the presence of coastal offering easily exploitable local intertidal resources. In contrast, during the Late Mesolithic, we observe a lagoon contraction and the reduction of lagoon bivalves size arguing for a decrease in resource productivity. This changes in the lagoon ecosystems negatively impacted to Late Mesolithic populations leading to a less intense occupation of this area. Therefore, the 700 years' temporal hiatus between the last hunter-gatherers and the first farmers occupying this area is explained by the disappearance of the formerly exploited biotopes because of sea-level rise, a situation that may have been aggravated by coincidence of the 8200 cal. BP climate event. The maximal sea transgression corresponded to a shift from intertidal to infralittoral species between the Impressa/Precardial and the Postcardial Neolithic, indicating a good adaptation to changing environments at that time. However, comparison between Late Mesolithic to Early Neolithic suggests that communities with different cultural baggage have had a different perception of the same environment. By the past perspective, it emphasises that perception of the ecosystem value as a benefit or constraint, and of the risks associated with sea-level rise, relies first on the local and regional scales adaptive capacity of society to global changes.

“…rates of Holocene tectonic movement in Silva et al, 2003). Although Holocene neotectonics are evidenced for the offshore Valencia Trough (Díaz del Río et al, 1986) and gentle subsidence for the Valencia area (Rey and Fumanal, 1996), neither we nor Calvo found evidence of significant Holocene faulting in the Palancia River watershed.…”

“…Hillslope colluvia, alluvial fans, and fluvial valley fills represent typical Pleistocene sediments (Rey and Díaz del Río, 1983;Estrela Navarro, 1986); Holocene deposits of the Palancia River watershed encompass localized soil-derived colluvial sheets, bouldery in-channel sediment, and alluvia on adjacent valley floors (IGME, 1974;Estrela Navarro, 1986;Segura Beltrán, 1990). Downstream of Sagunto (39°40.83′ N., 0°16.69′ W.), the Holocene fluvial record passes into delta facies, which laterally connect with a larger continuous strip of coastal plain deposits (Segura Beltrán, 1990;Rey and Fumanal, 1996;Mediato and Santisteban, 2006;Mediato et al, 2007a, b).…”

“…Geologically speaking, the study area is determined by craggy sandstone-made reliefs of Iberian direction from the Espadán mountain range. From a structural point of view, it infills a graben of the Upper Oligocene-Miocene age linked to the crisscrossing of orthogonal faults of Iberian orientation (northwest–southeast) with others running northeast–southwest, which produce a tectonic subsidence (Fontboté et al, 1990) that is also observed in the continental shelf (Rey and Fumanal, 1996). This depression is limited by faults parallel to the coastline that were filled during the Pliocene and Pleistocene with alluvial fan sediments (Pérez Cueva, 1979) grading to the coastal environment through barrier island marsh systems.…”

Evidence for Holocene sea level and climate change from Almenara marsh (western Mediterranean)

In the Almenara marsh (western Mediterranean), four cores were analyzed to establish the relationship between the marsh record of the Almenara marshlands and the environmental factors responsible for its evolution during the Holocene. One hundred and eighty-six samples were collected for sedimentologic and paleontological study: 63 for biomarker analysis; 5 for amino acid racemization (AAR) dating; and 5 for 14C dating. Litho and biofacies analyses identified distinct paleoenvironments, with the presence of a marsh environment alternating with inputs of alluvial material and marine sediments. Biomarkers indicated the constant presence of terrestrial (herbaceous) plants, together with a variable development of aquatic macrophytes. During the Holocene transgression, the Almenara marsh was occupied by oligohaline marsh facies with an oscillating water level and peat formation, which was established at the bottom of the record at 7570 cal yr BP and persisted until 3100±780 yr (AAR). Maximum surface flooding occurred at 5480 cal yr BP, registered 450m from the current coastline. At least three peat beds (dated with 14C dating and AAR) correlated with Bond (episode 5900 cal yr BP) and Wanner (episodes 4800–4500 and 3300–3500 cal yr BP) cycles and thus correspond to a regional model that affected the Northern Hemisphere.
