This review and synthesis weaves various multiproxy data into a single coherent narrative for the latest Pleistocene–Holocene paleoclimatic paleoceanographic evolution of Black Sea, Marmara Sea Aegean Sea. narrative, referred to as “Outflow Hypothesis” rests on several key observations interpretations which are incompatible with suggestion that post-LGM reconnection basin global ocean occurred ...
On wave-influenced river deltas, wave-driven sediment redistribution affects progradation, and therefore avulsions, while avulsions change where is delivered to the coastline, affecting coastline shape. Coastline shape, in turn, rates patterns. Here we use a numerical model investigate how asymmetry of wave climates delta avulsion behaviors, which are coupled with shape evolution. Increasing wa...
Babi}, Lj. & Zupani~, J.: Major events and stages in the sedimentary evolution of the Paleogene Promina basin (Dinarides, Croatia). Nat. Croat. Vol. 16, No. 4, 215-232, 2007, Zagreb. A study of sedimentary successions in different parts of the Eocene-Oligocene Promina basin has revealed major changes in the evolution of upper Promina Beds (PB). The first one refers to the origin of the erosiona...
Increasing global temperature and sea-level rise have led to concern about expansions in the distribution and prevalence of complex-lifecycle parasites (CLPs). Indeed, numerous environmental variables can influence the infectivity and reproductive output of many pathogens. Digenean trematodes are CLPs with intermediate invertebrate and definitive vertebrate hosts. Global warming and sea level r...
The aim of the study was to characterize a variety of microstructure development-levels and geotechnical property sequences of the late Pleistocene-Holocene deposits in the Mekong River delta (MRD), and the paper furthermore discusses the influences of delta formation mechanisms on them. The survey associated the geotechnical engineering and the sedimentary geology of the late Pleistocene-Holoc...
[1] Sediment fans are a potentially useful and underexploited recorder of Earth’s climatic and tectonic history, but historical observations have led to conflicting views on the importance of tectonic, climatic, and lithologic variables in controlling fan morphology and deposition. A one-dimensional model of a sediment fan and its associated catchment is used to explore the sensitivity of such ...
Abstract. Originating from the boreal forest and often transported over large distances, driftwood characterizes many Arctic coastlines. Here we present a combined assessment of radiocarbon (14C) dendrochronological (ring width) age estimates samples to constrain progradation two Holocene beach-ridge systems near Lena Delta in Siberian (Laptev Sea). Our data show that 14C ages obtained on synde...
The Remolar beach-dune system (700 m long and more than 100 wide, 070N direction) borders a campground that was closed (2003), due to the Barcelona airport expansion. In order recover restore dune ecosystem, series of soft measures were performed. After 10 years, study morphology, sedimentology, vegetation ecosystem carried out evaluate results these measures. For this purpose, topographic grou...
