Distribution characteristics and assessment of wind energy …
There is a trend of increasing wind energy density in the future along the coast of the South China Sea and the Bay of Bengal (Abolude et al., 2020). Coastal islands along Guangdong coasts are wind energy rich areas. Coastal and inland areas are exploitable and indigent areas, respectively (Mao et al., 2005; Wu, 1989).

Ecosystem vulnerability to extreme climate in coastal areas of China
China's coastal areas are located between the western Pacific Ocean and Eurasia, between 104°26'E and 125°47'E and 3°20'N and 43°29'N. The land area of China's coastal areas covers approximately 1.3 million km 2, accounting for approximately 14% of the national land area.The natural conditions of China's coastal regions are complex, consisting of marine and …

Geological mapping of basalt using stream sediment geochemical data
The orange ellipse in Fig. 12 (c) is the same connected area as the left part, which is identified as basalt from the field points and the geological map; this also shows the same zonal distribution as the basalt trend in the study area. However, most of this elliptical area was not predicted by the model.

Abstract. The southeastern coastal region is one of the most developed and populated areas in China. Meanwhile, it has been severely impacted by acid rain over many years. The chemical compositions and carbon isotope compositions of dissolved inorganic carbon (δ13CDIC) in river water in the high-flow season were investigated to estimate the chemical weathering and …

Level, distribution and sources of plutonium in the coastal areas of China
Plutonium is an important radioactive element in view of its biological toxicity and environmental impact. The two most important isotopes of plutonium, 239 Pu and 240 Pu, in the surface soil from the coastal area of China were determined using radiochemical separation combined with inductively coupled plasma mass spectrometry (ICP-MS) measurement. .
