Understanding deltaic resilience in the face of Holocene climate change and human impacts is an important challenge for the earth sciences in characterizing the full range of present and future wetland responses to global warming. Here, we report an 8000-year mass balance record from the Nile Delta to reconstruct when and how this sedimentary basin has responded to past hydrological shifts. In ...

Distribution of radionuclides in the soil samples, Infra-red stimulated luminescence dating techniques, electrical conductivity, pH measurements and grain size analysis of soils of the region between the Ganga and Yamuna Rivers (in the Upper Gangetic plain) have been studied. Soil characteristics are highly sensitive to climate changes and the degree of soil development indicated by higher thic...

We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska. We show the wet, percolation and dry snow zones located below 2700ma.s.l., at 2700 to 3900ma.s.l. and above 3900ma.s.l., respectively. We succ...

The upper part of the Krka River estuary and Prokljan Lake are a specific example well-stratified estuarine environment in submerged river canyon. Here, we reconstructed geomorphological evolution area classified data gathered study, integrating multibeam echosounder data, backscatter side-scan sonar morpho-bathymetric surveys, acoustic sub-bottom profiling, with addition ground-truthing sedime...

Diatoms are an important component of submarine biogenic sediments and often used for carrying out palaeoceanographical reconstructions. To understand the relationship between diatoms environment in western equatorial Pacific, from Holocene northern West Caroline Basin were selected analysis. We made quantitative statistics on divided diatom assemblages through cluster A total 53 species or var...

Most of the sediment components that accumulated in Elk Lake, northwestern Minnesota, during the Holocene are autochthonous or biogenic, delivered to the sediment-water interface on a seasonal schedule, preserved in distinct annual laminae (varves). The main allochthonous component is detrital clastic material, as measured by bulk-sediment concentrations of aluminum, sodium, potassium, titanium...

We examined functional, metabolic, and histological changes in the aortic tissue of rats after the period of warm ischemia ranging from 0 to 24 hours to determine the window of time in which grafts can be optimally viable for harvest. Sixty aortas from Brown Norway rats obtained after warm ischemia were used and changes in contraction, endothelial-dependent or -independent vasodilatation, cell ...

Few detailed case studies have been devoted so far to the Late Pleistocene palaeogeography of northern Mologa-Sheksna Lowland (MSL), compared adjacent regions covering Valdai glaciation marginal zone. Lake Beloye (Russia, Vologda region, Babaevo district) bottom sediments were studied using ground penetrating radar (GPR) and subsequently cored in order build a palaeoclimatic reconstruction for ...

Sediments from Lunkaransar dry lake in northwestern India reveal regional water table and lake level fluctuations over decades to centuries during the Holocene that are attributed to changes in the southwestern Indian monsoon rains. The lake levels were very shallow and fluctuated often in the early Holocene and then rose abruptly around 6300 carbon-14 years before the present (14C yr B.P.). Th...
