Stamukhi lakes are vast but little-explored Arctic ecosystems. They occur throughout winter, spring, and early summer near large river inflows along the Arctic coastline, and are the result of freshwater retention behind the thick barrier of rubble ice (stamukhi) that forms at the outer limit of land-fast sea ice. We examined the molecular biodiversity within all three microbial domains (Bacter...

salmas plain is located at the west of uremia lake and at the 75 km of north of uremia city. the main river of the plain, called zulachai, is drained into uremia lake. salmas aquifer is one of the coastal aquifers of uremia lake and has hydraulic connection with the lake. the recent draught occurrences and increased water consumption in agriculture and drinking sections water have not only caus...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

In the Bridge River mining camp the federal-provincial aeromagnetic maps, Tyaughton Lake (92Ji15) and Bridge River (92Ji16). at 1:63 360 scale, provide a ready base for analysis. Regional geological control is provided by current mapping and by the Geological Survey Branch (Open File Map 1987I I , Geology o j rhe Gold Bridge Area) and previous work by Leech (1953). Roddick and Hutchinson (1973)...

One surviving stronghold of endangered Northern swamp deer is Jhadi taal (lake) in Kishanpur Wildlife Sanctuary on the floodplains of Sharda River. Changes in channel characteristics and land use/cover in a stretch of the river were detected during 1948–2001 and their impact on deer habitat was assessed. Analyses revealed consistent shift of west bank line towards taal, moving to within 100 m i...

Combining morphological and genetic analysis, we compared patterns of diversification within and between morphs among sympatric European whitefish (Coregonus lavaretus L.) populations in Lake Femund, Norway. Seven external populations, from potential colonization routes into Lake Femund were included. We found that deep-, shallow-, river- and bay spawning populations are distinct morphs in Lake...

Abstract This paper presents the intelligent techniques approach for flood monitoring using Synthetic Aperture Radar (SAR) satellite images. We applied artificial neural networks and Self-Organizing Kohonen Maps (SOMs), to SAR image segmentation and classification. Our approach was used to process data from different SAR satellite instruments (ERS-2/SAR, ENVISAT/ASAR, RADARSAT-1/2) for differen...
