Examples from the Murray–Darling basin in Australia are used to illustrate different methods of disaggregation of reconnaissance-scale maps. One approach for disaggregation revolves around the de-convolution of the soil–landscape paradigm elaborated during a soil survey. The descriptions of soil map units and block diagrams in a soil survey report detail soil–landscape relationships or soil top...

A multi-user integrated suite of instruments designed to optimize the search for evidence of life on Mars is described. The package includes: -Surface inspection and surface environment analysis to identify the potential Mars landing sites, to inspect the surface geology and mineralogy, to search for visible surficial microbial macrofossils, to study the surface radiation budget and surface oxi...

Geographic information system (GIS) technology has been applied to analyze the offshore marine placer gold deposits at Nome, Alaska. Two geodatabases, namely Integrated Geodatabase (IG) and Regularized 2.5D Geodatabase (R2.5DG), were created to store and integrate digital data sets in heterogeneous formats. The IG served as a data warehouse and used to manage various geological data, such as bo...

Population statistics for As concentrations in rocks, sediments and ground water differ by geology and land use features in the New England region, USA. Significant sources of As in the surficial environment include both natural weathering of rocks and anthropogenic sources such as arsenical pesticides that were commonly applied to apple, blueberry and potato crops during the first half of the ...

Many distinct glacial episodes in the past ~1 million years Central Lowlands of North America left behind a patchwork glaciated landscapes different ages and formed through glacial, paraglacial, proglacial processes. Herein, we synthesize reconcile diverse data sources across nine states to create generalized landform regions map, incorporating information from surficial geology, age-constraine...

The Pontine Marshes (Central Italy) are known for their long drainage history starting early in Roman times and culminating reclamation ( bonifica integrale) by the Fascist’s regime under Mussolini, mostly 1930s of past century. geology this coastal wetland causes its problems received limited attention till recently. We reviewed results from recent studies, identified still existing knowledge ...
