The Nechako NATMAP project is a joint mapping venture between the Geological Survey of Canada (GSC) and the British Columbia Geological Survey Branch (BCGSB). This was the fifth and final year of the project which encompasses more than 30 000 square kilometres in central British Columbia (Figure 1). The primary objective of the project has been to improve the quality and detail of bedrock and s...

The factors that influence the invasion of natural habitats by nonnative plants remain poorly understood. We investigated abiotic, biotic, and human influences on the distribution and abundance of nonnative species in coastal upland habitats of southern New England and adjacent New York, US. We censused vegetation and sampled soils in 776, 20 · 20 m plots in natural areas and constructed a spat...

This paper quantifies rates of shoreline change and investigates the influence surficial geology on dynamics between 1950 2018 Pelly Island, located 10 km off Mackenzie Delta. Long-term changes in position were calculated using imagery analysis Analysing Moving Boundaries Using R (AMBUR). The exposure to predominant storm direction examined for northwestern southeastern zones. average annual li...

Abstract A new gravity survey (1164 stations and 180 samples for density analysis) combined with two geological cross sections has been carried out in a sector of the Central Pyrenees order to improve characterization basement cover architecture. From North South, study area comprises southern half Axial Zone northernmost part South-Pyrenean Zone. New data were previous existing databases obtai...

We argue for a surrcial pronunciation model: a model without underlying forms. The surrcial model outper-forms a traditional generative model by a signiicant margin on conversational speech (Switchboard) as well as on read speech (TIMIT). Our results suggest that the true mapping from underlying forms to surface forms is too complex to be accurately modeled using current techniques, and that we...

Seismic data are routinely used to infer in situ properties of earth materials on many scales, ranging from global studies to investigations of surficial geological formations. While inversion and imaging algorithms utilizing these data have improved steadily, there are remaining challenges that make detailed measurements of the properties of some geologic materials very difficult. For example,...

A geothermal reservoir causes inhomogeneity in the physical properties of the subsurface geology due to the high changes in temperature. These physical properties can be ob‐ served by means of varying anomalies from geophysical observations from the surface. These physical properties include electrical conductivity, rock density, magnetic suscepti‐ bility, rock elasticity, and, finally, the tem...

Acoustic seabed classification technologies measure acoustic diversity in the seafloor and surficial substrate. This diversity is generally well correlated with both geology and those benthic species which are keyed to geologic and biotic components of the seafloor. Remote acoustic seabed classification has reached a level of maturity and acceptance in the ocean community such that it should be...

The potential for basin amplification of ground motion from significant seismic sources 100-200 km (62-124 mi.) from the Las Vegas Valley (such as the Death Valley Fault System) and Quaternary faults in the valley could provide sufficient energy to cause liquefaction. Key criteria of liquefiable soils coupled with a shallow groundwater table (less than 15 m (50 ft)) are met at several sites in ...

We measured carbon, nitrogen, protein, bacterial and microalgal abundance, and minerals p e c ~ f ~ c surface area m sediments from the feeding zone of undisturbed Saccoglossus korualewskyi, as well as In their fresh egesta. Comparison of results using surficial material (> 1 mm) and the top 3 mm of sediments indicated ingestion of surficial material by the enteropneusts. Assuming the surficial...
