Elemental carbon and nitrogen geochemistry of a tropical peatland profile from the summit of Mount Kaala, Oahu, Hawaii

This dataset provides elemental carbon and nitrogen concentrations measured from a two-meter sedimentary organic (peat) deposit from the cloudforest peatland at the summit of Kaala on the Island of Oahu in the Hawaiian Islands. The base of the profile is ~45ka and accumulation spans the Last Glacial period in the central Pacific. Bulk samples were homogenized and sieved to <250 microns and analyzed by elemental analysis.

本数据集提供了从夏威夷群岛瓦胡岛卡拉山顶云雾林泥炭地采集的两米厚沉积有机质（泥炭）层（sedimentary organic deposit）中测得的元素碳（elemental carbon）和氮浓度。该剖面底部年代约为45千年（ka），沉积过程跨越了中太平洋的末次冰期（Last Glacial period）。整体样品（bulk samples）经均质化处理后过250微米（microns）筛，再通过元素分析（elemental analysis）检测。
