Topographic correction for ground penetrating radar for enhanced detection of dike subsurface anomalies

open access: yesScientific Reports
Dikes are critical components of flood control infrastructure in China. Ground-penetrating radar (GPR) is widely used for non-destructive detection of subsurface anomalies (e.g., cavities, seepage paths, and soil loosening) in dikes.

An Assessment of GCM Performance at a Regional Scale Using a Score-Based Method

open access: yesAdvances in Meteorology, 2018
A multicriteria score-based method was developed to assess the performances of 18 general circulation models (GCMs) in the study region from 1970 to 2005. The results indicate the following. (1) GCMs simulate temperature better than rainfall.

Assessing the freshwater distribution of yellow eel [PDF]

open access: yes, 2008
In the global context of the decline in wild species, modeling the distribution of populations is a crucial aspect of ecological management. This can be a major challenge, especially for species, such as the European eel, that have complex life cycles ...

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]

open access: yes, 2019
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.

Effects of Spring Dust Aerosols on Direct Radiative Forcing in China from 2000 to 2020

open access: yesRemote Sensing, 2023
In order to understand the mechanism of dust aerosol influence on regional climate change, it is crucial to quantify the radiative forcing effect of dust aerosols. However, studies on the direct radiative forcing of dust aerosols over long time series in

Geochemistry of reduced inorganic sulfur, reactive iron, and organic carbon in fluvial and marine surface sediment in the Laizhou Bay region, China [PDF]

open access: yes, 2015
Understanding the geochemical cycling of sulfur in sediments is important because it can have implications for both modern environments (e.g., deterioration of water quality) and interpretation of the ancient past (e.g., sediment C/S ratios can be used ...
