Age-depth models for Pb-210 datasets (NERC Grant NE/V008269/1)

Age-depth models for Pb-210 datasets. The St Croix Watershed Research Station, of the Science Museum of Minnesota, kindly made available 210Pb datasets that have been measured in their lab over the past decades. The datasets come mostly from North American lakes. These datasets were used to produce both chronologies using the 'classical' CRS (Constant Rate of Supply) approach and also using a recently developed Bayesian alternative called 'Plum'. Both approaches were used in order to compare the two approaches. The 210Pb data will also be deposited in the neotomadb.org database. The dataset consists of 3 files; 1. Rcode_Pb210.R R code to process the data files, produce age-depth models and compare them. 2. StCroix_agemodel_output.zip Output of age-model runs of the St Croix datasets 3. StCroix_xlxs_files.zip Excel files of the St Croix Pb-210 datasets

铅-210（Pb-210）数据集的年代-深度模型。明尼苏达科学博物馆（Science Museum of Minnesota）旗下的圣克罗伊流域研究站（St Croix Watershed Research Station）慷慨共享了其实验室近几十年来测得的210Pb数据集。该批数据集主要采集自北美湖泊。研究团队基于上述数据集，分别采用“经典”恒定供给速率（Constant Rate of Supply, CRS）法，以及新近开发的贝叶斯替代方法“Plum”构建了沉积物年代序列，并通过两种方法联用开展二者的对比分析。该210Pb数据集亦将上传至neotomadb.org数据库。本数据集包含3个文件：
1. Rcode_Pb210.R：用于处理数据文件、生成年代-深度模型并开展模型对比的R代码脚本；
2. StCroix_agemodel_output.zip：圣克罗伊数据集的年代模型运行结果压缩包；
3. StCroix_xlxs_files.zip：圣克罗伊铅-210数据集的Excel文件压缩包。
