Data underlying the research on: Carbon fluxes and methane cycling in Lake Wudalianchi, northeastern China

This dataset contains alkenone isomer index, inferred salinity, GDGTs (GDGT-0/crenarchaeol), diploptene, lignin, and bulk organic carbon and nitrogen in Lake Wudalianchi downcore. (The data of the GDGTs, diploptene, lignin, and bulk organic carbon and nitrogen only contain the depth above ~21 cm of the sediment core).

本数据集收录五大连池湖沉积物岩芯中的烯酮异构体指数、推断盐度、甘油二烷基甘油四醚脂（GDGTs，含GDGT-0/泉古菌醇（crenarchaeol））、升藿烯、木质素以及总有机碳与总氮数据。其中，甘油二烷基甘油四醚脂、升藿烯、木质素以及总有机碳和总氮的相关数据仅覆盖沉积物岩芯约21 cm以浅的深度范围。
