Spatiotemporal characteristics and dominant dimensions of modern marine ranching development in China
Modern marine ranching (MMR) in China represents a crucial strategy for balancing fishery production and ecosystem health, yet its development exhibits significant regional variation. This study introduces a novel, five-dimensional evaluation framework—encompassing marine resources, market economy, ecological civilization, science–technology talent, and government support—to analyze MMR's spatiotemporal dynamics. Panel data from 2011–2021 reveal a narrowing of regional disparities and highlight the growing importance of innovation and human capital.

Some coastal cities are sinking faster than the ocean is rising
Coastal communities face a compounding threat beyond rising sea levels: accelerated land subsidence. New research validates that densely populated coastal regions experience an average relative sea-level rise of approximately 6 millimeters annually – almost three times the global average. Contributing factors include groundwater extraction, urban development, and geological processes. This phenomenon significantly amplifies coastal vulnerability. For further exploration of related environmental challenges, see our article, "Earth’s waters are quietly running out of oxygen, scientists warn," which details a concerning decline in oceanic oxygen levels.

Detecting the sensitive area of evaporation duct and evaluating its impact on forecasts of electromagnetic propagation over the South China Sea
Accurate forecasting of electromagnetic (EM) propagation over the South China Sea is critical for reliable maritime communication and radar detection, yet hampered by evaporation ducts—atmospheric phenomena that distort radio waves. This study employs the nonlinear local Lyapunov exponent (NLLE) method to identify sensitive areas of forecast error for evaporation duct heights, revealing a concentration along the coasts of China and Vietnam. Excluding these sensitive regions demonstrably improves EM propagation path loss forecasts, though the impact varies by year.
