Branched tetraether lipids in Carminowe Creek catchment (southwest England)@en

In this dataset, the branched glycerol dialkyl glycerol tetraethers (brGDGTs) data in a creek catchment located in southwest England are included, with 78 soil samples along 14 soil transects from hilltop to downslope, including 31 arable land sites, 14 permanent grassland sites, 24 temporary grassland (ley) sites and 5 woodland sites, 7 riverbed sediments at three locations along each of the two tributaries (upstream, midstream and downstream), and one more at the joint outlet, and a 50 cm long sediment core in the lake, which is about 150 m away from the joint outlet. […]本数据集收录了英格兰西南部某溪流域的支链甘油二烷基甘油四醚（branched glycerol dialkyl glycerol tetraethers，brGDGTs）相关数据。其中包含沿14条从山顶至坡下的土壤样带采集的78份土壤样品，涵盖31份耕地样点、14份永久草地样点、24份临时草地（轮作草地，ley）样点与5份林地样点；另采集了7份河床沉积物样品，来自两条支流的上、中、下游各3个点位，以及汇流口处1份样品；同时包含一根采自距汇流口约150米处湖泊的长50厘米沉积岩芯。[…]
