Abstract Variations in East Asian summer monsoon (EASM) precipitation impact agriculture, water resources, electricity generation, and economic development the densely populated region of central eastern China. However, uncertainties remain history driving mechanisms changes this over past two millennia. We present an 1800 yr multiproxy reconstruction based on hydroclimate variations inferred from Lake Nvshan sediments Jiang-Huai find that rainfall was higher during Little Ice Age (LIA) than...
Abstract More than 10% of the world's population lives in East Asian monsoon (EAM) region, where precipitation patterns are critical to agricultural and industrial activities. However, dominant forcing mechanisms driving spatiotemporal changes EAM remain unclear. We selected Holocene records tracking region reconstructed from pollen data explore changes. Our analysis shows a time-transgressive pattern maximum precipitation, with earlier occurrence southern area later northern area. The...
Abstract Changes in the El Niño Southern Oscillation over last few decades have been linked to anthropogenic greenhouse gas emissions; however, sign, magnitude, and drivers of these variations during Common Era are not yet well constrained. Here, we present an 1800-year reconstruction mean-state derived from precipitation reconstructions based on lake sediments East Asia examine long-term changes mean state variance tropical Pacific. We find that Medieval Warm Period was characterized by La...
The total organic carbon (TOC) content in lake sediments is an effective archive indicating past climate changes. However, the resolution of TOC record has generally been limited by factors such as subsampling intervals, hampering further comprehension change. Recently, hyperspectral imaging technology increasingly employed to scan sediment cores, presenting new opportunities reconstruct high-resolution sequences, but reconstruction long-term records using and implications have not well...
Abstract The timing of the Holocene summer monsoon maximum (HSMM) in northeastern China has been much debated and more quantitative precipitation records are needed to resolve issue. In present study, temperature changes were quantitatively reconstructed from a pollen record sediments Tianchi Crater Lake using plant functional type-modern analogue technique (PFT-MAT). indicates gradual increase during early mid-Holocene HSMM at ~5500–3100 cal yr BP, while exhibits divergent pattern with...
Abstract. Hypolimnetic anoxia in eutrophic lakes can delay lake recovery to lower trophic states via the release of sediment phosphorus (P) surface waters on short timescales shallow lakes. However, long-term effects hypolimnetic redox conditions and state sedimentary P fraction retention deep are not clear yet. withdrawal P-rich water is predicted diminish seasonal recycling from hypolimnion. Nevertheless, there a lack evidence well-dated cores, particular lakes, about impact retention. In...
Abstract. Global spread of hypoxia and less frequent mixing in lakes is a major growing environmental concern. Climate change human impact are expected to increasingly deteriorate aquatic ecosystems. The study processes drivers such changes the past provides great asset for prevention remediation future. We used multiproxy approach combining high-resolution bulk pigment data measured by hyperspectral imaging (HSI) with lower-resolution specific chlorophyll types carotenoids HPLC examine...
Northern China, particularly the Yellow River Basin, which is birth place of Chinese civilization and has been political center throughout most China's history, an ideal region for studying response human activities to climate change. However, studies on links between change variations in earlier are limited due scarcity macroscale monsoon precipitation records. In present study, a ~4,000-year record precipitation, represents average rainfall large areas northern was reconstructed from...
