“…3d), which is interpreted as the aeolian saltation component in the lake sediments (e.g. Sly, 1978;Sun D. et al, 2002;Xiao et al, 2012). Fluvial sand has isolated features in the grain-size distribution and specific grain-size ranges, which are, respectively, the wellsorted saltation (ca.…”

Abstract. The Taklimakan Desert in the Tarim Basin is the largest desert in Central Asia, and is regarded as one of the main dust sources to the Northern Hemisphere. Late Cenozoic sedimentary sequences with intercalated in-situ aeolian dune sands in this area preserve direct evidence for the Asian desertification. Herein, we report a high-resolution multiproxy climatic record from the precise magnetostratigraphic dated Hongbaishan section in the central Taklimakan Desert. Our results show that a fundamental climate change, characterised by significant cooling, enhanced aridity, and intensified atmospheric circulation, occurred at 2.8 Ma. Good correlations between paleo-environmental records in the dust sources and downwind areas suggest a broadly consistent climate evolution of northwestern China during the late Cenozoic, which is probably driven by the uplift of the Tibet Plateau and the Northern Hemisphere glaciation.

“…After initial deposition near shore, waterlogged twigs and leaves are transported into deeper water during high-wave events, where they accumulate at depths just below wave base (cf., Sly, 1978). As the water calms, suspended silt and clay settle out on top of the plant debris.…”

Many of the physical and biological processes that characterize arctic ecosystems are unique to high latitudes, and their sensitivities to climate change are poorly understood. Stratigraphic records of land-surface processes and vegetation change in the Arctic Foothills of northern Alaska reveal how tundra landscapes responded to climatic changes between 13,000 and 8000 14 C yr BP. Peat deposition began and shrub vegetation became widespread ca. 12,500 14 C yr BP, probably in response to the advent of warmer and wetter climate. Increased slope erosion caused rapid alluviation in valleys, and Populus trees spread northward along braided floodplains before 11,000 14 C yr BP. Lake levels fell and streams incised their floodplains during the Younger Dryas (YD) (11,000-10,000 14 C yr BP). A hiatus in records of Populus suggest that its geographic range contracted, and pollen records of other species suggest a cooler and drier climate during this interval. Basal peats dating to the YD are rare, suggesting that rates of paludification slowed. Immediately after 10,000 14 C yr BP, lake levels rose, streams aggraded rapidly again, intense solifluction occurred, and Populus re-invaded the area. Moist acidic tundra vegetation was widespread by 8500 14 C yr BP along with wet, organic-rich soils. Most of these landscape-scale effects of climatic change involved changes in moisture. Although low temperature is the most conspicuous feature of arctic climate, shifts in effective moisture may be the proximate cause for many of the impacts that climate change has in arctic regions. r

“…Several investigators have proposed theories for the origin and maintenance of the bnl in the Great Lakes. These include local resuspension (Chambers and Eadie 1981, Sandilands and Mudroch 1983, Rosa 1985, Baker and Eisenreich 1989, Halfman and Johnson 1989, Mudroch and Mudroch 1992, downslope advection of nearshore material (Halfman and Johnson 1989), and settling of biogenic material (Sly 1994). Although time series measurements of both current velocity and water transparency are required to test these hypotheses, none were made in any of these studies.…”
