To address the knowledge gap concerning the behavioral dynamics of dissolved organic matter (DOM) in the Changjiang Estuary during the late flooding season, we conducted an extensive sampling campaign during which 188 water samples were systematically collected across the estuary from August 15th to September 4th, 2021. Through analysis of dissolved organic carbon (DOC) concentrations and optical properties, this study aimed t...

A tree‐ring stable oxygen isotope (δ 18 O) chronology was developed for the past 171 years by four Abies pindrow trees growing in southwest foothills of High Asia, northern Pakistan, which is correlated with observed and modelled δ 18 O of precipitation in Islamabad over the instrumental period. The averaged tree‐ring δ 18 O chronology is significantly negative correlated with local ( r = −.651, p n = 38) and regional ( r = −....

The dissolved organic matter (DOM) in the ocean is a large carbon pool that plays an important role in the global carbon cycle. Investigation of the characteristics and behaviors of DOM in some areas facilitates a better understanding of biochemical processes in the water column. In February 2020, water samples were collected to characterize the distribution and optical properties of DOM from the Northern Andaman Sea and the N...

China is drastically influenced by the Asian monsoon. Based on the relationship ( r = −.636, N = 62, p 18 O values from nine cores of Pinus tabulaeformis Carr. from Nanwutai and the Asia monsoon‐related June–August relative humidity (RH JJA ), we designed a transfer function reconstructing the RH JJA variation from 1760 to 2018 CE. Our RH JJA reconstruction captured some extreme climatic events that occurred in the past, such...

Tree‐ring densitometric studies conducted in semi‐arid regions are exceedingly rare. In this study, we evaluate a new maximum latewood density chronology from a collection of Picea purpurea trees growing in semi‐arid northwestern China for climatic reconstruction purposes. We find statistically significant correlations between annual maximum density variations and July–September maximum temperatures over the 1957–2014 calibrat...

The understanding of past millennium climate change is very important. Due to the lack of continuously annual resolution records, the temperature characteristics in the low‐latitude regions of East Asia (LLREA) during past several centuries are still unknown. Using tree‐ring width chronology from Taiwan, an island located in the western Pacific region and in southeastern China, February–October mean temperature from 1380 to 20...
