Goring - THE NEOTOMA PALEOECOLOGY DATABASE: BUILDING COMMUNITIES AROUND PALEOECOLOGICAL DATA

GORING, Simon, Department of Geography, University of Wisconsin, 550 N Park St, Madison, WI 53706

The Neotoma Paleoecology Database serves global change science by providing a community-curated data resource (CCDR) for paleoecological and associated paleoenvironmental data. Neotoma currently holds over 4 million individual observations in over 31,000 datasets and 15,000 sites. Major dataset types stored include fossil pollen, vertebrate records, diatoms, ostracodes, testate amoebae, insects, macroinvertebrates, and charcoal, and the data model can be readily extended to other data types. The database also stores 5,000 geochronological age controls, mostly radiocarbon dates, along with associated age-depth model metadata and age inferences. Neotoma includes surface sample datasets with associated environmental variables for data calibration. Data upload, cleaning, and curation are performed by Data Stewards using the Tilia software system, with validation steps including checks of variable names, geographic coordinates, and site name duplication. Neotoma data can be explored and visualized using the map-based Neotoma Explorer and obtained using RESTful Application Programmatic Interfaces (APIs) and the neotoma R package. Third-party websites and apps drawing on Neotoma include the NOAA WDC-Paleoclimatology data portal, the Earth Life Consortium APIs for paleobiological data, the Global Pollen Project, and Flyover Country. Neotoma is governed by an elected Neotoma Leadership Council and welcomes community data contributions, new members, and new stewards.

Neotoma古生态学数据库致力于全球变化科学研究，通过提供由社区共同维护的古生态学及相关古环境数据资源（CCDR），为学术界提供支持。Neotoma数据库目前存储了超过4百万条独立观测数据，涵盖31,000个数据集和15,000个地点。主要数据集类型包括化石花粉、脊椎动物记录、硅藻、 ostracodes、有壳变形虫、昆虫、大型无脊椎动物和木炭等，其数据模型能够方便地扩展至其他数据类型。数据库还存储了5,000个地质年代控制点，主要涉及放射性碳年代测定，以及相关的年代-深度模型元数据和年代推断。Neotoma包括表面样本数据集及其相关的环境变量，以供数据校准使用。数据上传、清洗和整理由数据管理员使用Tilia软件系统进行，验证步骤包括变量名称、地理坐标和地点名称重复性的检查。Neotoma数据可通过基于地图的Neotoma Explorer进行探索和可视化，并可通过RESTful应用程序编程接口（APIs）和neotoma R包获取。借助Neotoma的数据，第三方网站和应用包括NOAA WDC-Paleoclimatology数据门户、地球生命联盟的古生物学数据API、全球花粉项目以及飞越国家等。Neotoma由选举产生的Neotoma领导委员会管理，并欢迎社区的数据贡献、新成员和新管理员。
