Chlorophyll-a (Chl-a) concentration is a key indicator of coastal ecosystem health, reflecting both primary productivity and the ecosystem’s response to climate change and human activities. This study quantifies long-term Chl-a trends in the Yellow and Bohai Seas using a multi-source remote sensing reconstruction dataset generated with deep learning algorithms. Quantile regression was applied to assess changes across the 75th,...

The changes of annual average, minimum and maximum temperature ( T avg , T min and T max ) in China over 1961–2020 were examined based on the Chinese gridded observation dataset (CN05.1), and the relative contributions of T min and T max to the tendency of T avg were addressed. The results show that the nationwide mean warming rate reached 0.29°C·decade −1 for T avg , 0.39°C·decade −1 for T min and 0.24°C·decade −1 for T max ,...

Previous studies have suggested that westward-migrating mesoscale eddies are a dominant factor that modulate the interannual Kuroshio intensity in the East China Sea (ECS), indicating a close positive correlation between them. According to the extended record of altimetry-based sea level anomalies (SLAs) until 2020, however, the interannual variation of the Kuroshio intensity no longer has a strong positive correlation with ed...
