TL;DR: In this article, multi-proxy analysis of a sediment core from Qinghai Lake, including pollen, carbonate, TOC, TN and δ 13 C of organic matter, was used to document regional climatic changes during the last 18,000 years.

TL;DR: A major extinction of intermediate-water benthic foraminiferal species coincided with a major decrease in terrestrial organic matter (n-C29 alkane) and whole rock sulfide in a continuous siltstone sequence in the Tawanui Section (46°S paleolatitude) along the Akitio River, southeastern North Island, New Zealand, in the middle part of the uppermost Paleocene nannofossil zone (CP8) as discussed by the authors.

TL;DR: In this paper, the late Pleistocene and Holocene hydrologic balance of Chaka Salt Lake in the eastern Qaidam Basin of NW China was studied based on the analysis of lithostratigraphy, mineralogy, total organic carbon, and total nitrogen from a 9.0m long sediment core.

TL;DR: In the MITI Nankai Trough as discussed by the authors, a total of six wells were tested, including the main well, two pilot wells, and three post survey wells at intervals of 10-100 m. All the wells except the first confirmed the occurrence of hydrates based on logging-while-drilling, wire-line logging and/or coring using a pressure and temperature coring system.

TL;DR: In this paper, the vegetation and climate of the westerly dominated areas in Central Asia during the Holocene were interpreted using pollenassemblages and charcoal data from a 300-cm-long sediment core of the Sayram Lake, northern Xinjiang.
