How to Deal With Multi-Proxy Data for Paleoenvironmental Reconstructions: Applications to a Holocene Lake Sediment Record From the Tian Shan, Central Asia

Sediment Organic Carbon Sequestration of Balkhash Lake in Central Asia

“…Although lake water occupies a small surface area of the Earth, more and more studies have shown that lakes are a carbon sink with a disproportionate effect on the global carbon cycle [11][12][13], and the lake carbon storage plays an important role in mitigating climate change [14]. There are many lakes in Central Asia, but the research on lake sediments in Central Asia has mainly Sustainability 2021, 13, 9958 2 of 12 focused on the evolution and reconstruction of the climate environment [15][16][17][18]. Sediment organic carbon is an important global carbon sink; however, an in-depth understanding of the influences of climate change and anthropogenic factors on sediment organic carbon sequestration is still lacking, making this region one of the most uncertain regions in the assessment of the global carbon balance.…”

“…Mischeke et al [19] used ostracod species assemblages and shell chemistry to estimate the lake level and lower salinity over the last 2900 years. Although there is still a lack of understanding of the dynamic changes in carbon burial in Balkhash Lake, studies have found that arid regions may have great potential for carbon sequestration and carbon storage [18,19]. In particular, the responses of organic carbon sequestration to climate change are still unclear in Central Asia.…”
