A complex system of muddy fluid-discharging and methane (CH4)-releasing seeps was discovered in a valley of the river Mukhrinskaya, one of the small rivers of the Irtysh Basin, West Siberia. CH4 flux from most (90%) of these gas ebullition sites did not exceed 1.45 g CH4 h(-1), while some seeps emitted up to 5.54 g CH4 h(-1). The δ(13)C value of methane released from these seeps varied between ...

Forty two Paleocene benthic foraminiferal species of the Midway Formation in the Gulf Coastal Plain of Texas, USA were firstly investigated by Plummer (1927), and its paleogeographic distribution in some other countries in the Tethyan province were recorded: North America (USA, Mexico), South America (Argentina), Europe (North Sea Basin, Spain, France, Italy, Czech Republic, Bulgaria), North Af...

Boreal peatland covers large areas on the northern hemisphere and thus plays an important role especially as carbon storage. Results from a range of microwave sensors have already shown a large potential for hydrological applications. We tested the ScanSAR system ENVISAT ASAR Global Mode (1km) time series for wetland monitoring in boreal environments. With a simple threshold method homogeneous ...

We present the preliminary results of our recent find, a circular pond, and its surrounding structures, built in stone masonry Sasanian tradition Dehbarm village, west Firuzabad Plain (Fars, Iran). elaborate on this site suggest it belongs to Early Ardashir-Xurra (Ardaš?r-Xwarrah), first capital complex urban plan plain. Based comparable finds, we interpret as garden settlement, so-called parad...

Abstract Boreal summer extratropical intraseasonal oscillation (EISO) is crucial in modulating regional subseasonal variation and particularly causing extreme meteorological events, but it has yet to be well clarified operationally monitored. This study first objectively sorts out three dominant EISOs trapped along two westerly jet streams over Eurasia, then proposes the corresponding real-time...

Two new species of genus Alona Baird, 1843 were found in regions along the south-east border of Asian Russia. Alona irinae sp. nov. was found in a lake in the plain of the Zeya River, a north tributary of the Amur River, and in a lake in the steppe region along the West coast of Baikal. Alona floessneri sp. nov. inhabits saline lake Uvs-Nuur on the border of Russia and West Mongolia, and severa...

Analyzing the process of land use and cover changes during long periods of time and predicting the future changes is highly important and useful for the land use managers. In this study, the land use maps in the Ardabil plain in north-west part of Iran for four periods (1989, 1998, 2009 and 2013) are extracted and analyzed through remote sensing technique, using the land-sat satellite images. T...
