Heard Island contains a system of lava tube caves in a largely pristine condition which are the best developed bedrock caves known in Antarctic or Subantarctic latitudes. They require special management, because of significant and sometimes fragile attributes associated with cave geomorphology, geology, hydrology, atmospheres, soils, microbiology, flora, fauna, vertebrate palaeontology, archaeo...

Applications of LiDAR remote sensing are exploding, while moving from the research to the operational realm. Increasingly, natural resource managers are recognizing the tremendous utility of LiDAR-derived information to make improved decisions. This review provides a cross-section of studies, many recent, that demonstrate the relevance of LiDAR across a suite of terrestrial natural resource dis...

Land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. The rate of thisphenomenon is high in developing countries such as Iran. This research investigated desertification and mapping ofdesertification in Abuzaydabad, near Kashan, Iran, with an emphasis on land criteria using an IMDPA model.Different studies have assessed land degradation or desertificat...

Abstract The objective of this research is to identify groundwater potential zones for Bangladesh. Fourteen influential factors associated with topography, geology and meteorological concerns were applied study. Weights sub-factors within a factor calculated based on pairwise comparisons. delineated through GIS-based weighted overlays maps. According the comparison, consistency ratios allowable...

Climate change is amplified in the Arctic, and establishing baseline data for its current character important. Here we present a map of geomorphology Femmilsjøen area, Spitsbergen, northern Svalbard. The regional physiography characterised by low-relief, high elevation mountain plateau, high-relief steep slopes, low-relief coastal lowlands. results indicate that glaciers were most likely warm-b...
