متن کاملP eriodicity of Holocene climatic variations in the Huguangyan Maar Lake
There exist five primary periods of 2 930, 1 140, 490, 250 and 220 a in the Holocene climatic variations in the Huguangyan Maar Lake, according to the energy-spectrum and filter analyses of high-resolution time sequences (10 15 a) of the sediment dry density. The peak values of the three temperature-decreasing periods with the 2 930 a cycle occur at about 7 300, 4 250 and 1 200 Cal. aBP. There ...
متن کاملLate Holocene climatic changes in Garhwal Himalaya
Geochemical study of a 3.55 m long lake sediment core from the Badanital Lake (Garhwal Himalaya) reveals Late Holocene centennial-scale climatic changes. The ecosystem of the tectonically formed lake seems to be controlled by natural and anthropogenic factors. The imprints of four major global events, e.g. 4.2 ka event, Medieval Warm Period (MWP), Little Ice Age (LIA) and modern warming are obs...
متن کاملHolocene-Late Pleistocene Climatic Ice Core
Three ice cores to bedrock from the Dunde ice cap on the north-central QinghaiTibetan Plateau ofChina provide a detailed record of Holocene and Wisconsin-Wurm late glacial stage (LGS) climate changes in the subtropics. The records reveal that LGS conditions were apparently colder, wetter, and dustier than Holocene conditions. The LGS part of the cores is characterized by more negative 8180 rati...
متن کاملMarine EM Climatic Parameters
Recently there has been increased interest within the U.S. Navy in the use of climatology-based products to support the planning and execution of military operations. Climatological databases of atmospheric features that impact electromagnetic (EM) propagation have been developed to provide guidance on weapons and sensor system performance for expected environmental conditions. However, the mar...
