Noise learning of audio magnetotellurics data with a combination of inception multi-scale residual and dual-decoder U-Net

Abstract Audio magnetotellurics (AMT), as a commonly used reliable geophysical technique, provides outstanding metal ore exploration capabilities based on the resistivity structure of the earth. However, the accuracy of data acquisition is significantly impacted by external elect...

A Transfer Learning and Data Augmentation Approach for Classifying Field Images of Granite Residual Slope Soils

Granite residual and slope-wash soils are important disaster-prone geological bodies in the hilly and mountainous areas of Hunan Province, China. Their engineering classification has long relied on manual visual inspection and laboratory testing, which is inefficient and subjecti...

How Much Water Can Be Seasonally Buffered by China's Largest Floodplain Lake? A Refined Estimate From SWOT

Abstract Poyang Lake, China's largest floodplain lake, plays a crucial role in regional hydrology by seasonally regulating water to mitigate floods and sustain extensive wetland ecosystems. However, complex hydrodynamics and significant spatial hydraulic gradients often invalidat...
