A systematic regional geochemical stream sediment survey for base metals copper, lead, and zinc over an area of 200 sq.km was carried out around Wapsa in Solukhumbu District. samples were collected from active streams analyzed them using atomic absorption spectrometry (AAS) method. All chemical analysis data interpreted with geostatistical inverse distance weighing (IDW) multivariate interpolat...

Quantifying catchment-scale soil property variation yields insights into critical zone evolution and function. The objective of this study was to quantify and predict the spatial distribution of soil properties within a high-elevation forested catchment in southern Arizona, USA, using a combined set of digital soil mapping (DSM) and sampling design techniques to quantify catchment-scale soil sp...

Abstract Bangka Belitung Archipelago is well known as tin mining production in Indonesia. The activity was performed on land and offshore area which affect the shoreline total suspended solid distribution especially at Pangkalpinang sea water. aim of this study to evaluate (TSS) compare with oceanography parameters (current wave). concentration TSS analysed laboratory by gravimetric solids. Thi...

Abstract. The Malaysian government implemented the Movement Control Order (MCO) from March 18 to May 13, 2020, in an effort curb coronavirus disease outbreak that had spread throughout nation. Utilizing data GOSAT, GOSAT-2, OCO-2, OCO-3, and TROPOMI, total column-averaged dry-air mole fraction of carbon dioxide methane (referred as XCO2 XCH4) is employed examine patterns both gases MCO well sam...

Aim Species distribution maps are essential for assessing extinction risk and guiding conservation efforts. However, most come sourced as expert-drawn range with known issues of accuracy or developed overly complex modelling procedures. Thus, data-driven alternatives that accessible reliable a welcome addition to the spatial toolkit. Here, we geospatial workflow refine species from its extent o...

Abstract In Wrocław over the past 20 years, recorded increase in average ambient air temperature is approx. 0.5 °C. addition, urbanisation has created a phenomenon called Urban Heat Island (UHI). The combined effect of UHI and climate change can influence groundwater by penetrating underground. elevated temperatures urban areas Subsurface (SSUHI). This study focuses on spatial distribution shal...

groundwater quality management is one of the most important issues in many arid and semi-arid regions, including iran.nitrate (no3-) is one of the most common anions contaminating groundwater. this study aimed to range nitrateconcentrations in water resources in bahabad plain in yazd province. to evaluate the nitrate data in this descriptive study,260 nitrate samples from 13 wells in bahabad we...

The spatial variation of crop yield was mainly caused by the complicated factors, such as soil and land factors. Based on sound theoretical reasoning, the paper performed an exploratory investigation of the relationship between the spatial distribution of yield measurement about 849 samplings on Thiessen polygon. Reasonable sample size or sampling density is an assurance of yield estimation sur...

As the development of earth sciences and cross-disciplinary, it’s more and more meaningful and valuable to analyze and estimate precipitation spatial distribution. Precipitation spatial information is important in many fields, such as water resource management, drought and flood disaster predication, and regional sustainable development. It’s unrealistic to get the accurate predication of a par...
