We present the first continuous middle through late Pleistocene record of fossil ostracods from Maldives in northern Indian Ocean, derived sediment cores taken at Site U1467 by Expedition 359 International Ocean Discovery Program (IODP). lies 487 m water depth Inner Sea archipelago, an ideal place for studying effects South Asian Monsoon (SAM) system on primary productivity, intermediate ocean ...

Abstract Extent and chronology of 24 buried seabed-exposed mass transport deposits (MTDs) on the continental slope Canadian Beaufort Sea were compiled towards a regional geo-hazard assessment region. A total 2220 lines 3.5 kHz sub-bottom profiler (SBP) data (~40,000-line kilometres) covering an area 9740 km2 analyzed to allow new understanding instability in Several sediment cores acquired acro...

the main issues about relation between climate and relief in the romanian geomorphological literature follow three directions of research: the description of pleistocene glacial and pleistocene-holocene periglacial landforms in the carpathians; the direct analysis of climate?s role in landform development; the integration of separate works and findings in a synthetic morphodynamic system applic...

the altitude to which the past glaciers had been extended during the last glacial period in dinevar basin, western iran, can be estimated based on glacier-geomorpic evidence such as cirques, u-shaped valleys, and the moraines in lowlands. this study estimates the elevation of snowline during this period for the basin as the objective of the research. topographic and geologic maps, landsat image...

The morphology of the western Alps has been strongly influenced by Quaternary glaciations. On the basis of observations of glacial morphology in the Belledonne, Grandes-Rousses, Taillefer and Pelvoux-Ecrins Massifs (south-eastern France), we reconstitute the glacial trimline and equilibrium line altitude (ELA) during the most extensive glaciation (MEG). Our best estimate of the MEG ELA is 1800±...

The sedimentary sequences found within estuaries in the north west Nelson region of central New Zealand are investigated order to quantify timing end Post Glacial Marine Transgression. This has been identified as being relatively stable terms vertical tectonic movement during Holocene, but is yet yield any reconstructions eustatic sea level. In this study, we investigate Holocene infill a barri...

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 ...

The Imlay Channel in Lapeer County, Michigan, was one of two outlets for the glacial Lake Maumee phase ancestral Erie. Fifteen new radiocarbon and optical ages from within adjacent to constrain sedimentation rates channel timing regional deglaciation. For nearly 50 years, deglaciation this region Michigan has been based on a single age Weaver Drain site located near Channel, 16.7–17.0 cal ka BP...

[1] Climate change indirectly alters the distribution of tectonic uplift at active orogens by modifying the action of surface processes, which in turn alters mountain topography. The impact of alpine glaciation on tectonic activity is explored here. The predictions of previous analytical, critical wedge models are compared with the output of a numerical model that explicitly couples rock uplift...
