Location Identifiers, Metadata, and Map for Field Measurements at the East River Watershed, Colorado, USA (Version 3.0)

This dataset contains identifiers, metadata, and a map of the locations where field measurements have been conducted at the East River Community Observatory located in the Upper Colorado River Basin, United States. This is version 3.0 of the dataset and replaces the prior version 2.0, which should no longer be used (see below for details on changes between the versions). Dataset description: The East River is the primary field site of the Watershed Function Scientific Focus Area (WFSFA) and the Rocky Mountain Biological Laboratory. Researchers from several institutions generate highly diverse hydrological, biogeochemical, climate, vegetation, geological, remote sensing, and model data at the East River in collaboration with the WFSFA. Thus, the purpose of this dataset is to maintain an inventory of the field locations and instrumentation to provide information on the field activities in the East River and coordinate data collected across different locations, researchers, and institutions. The dataset contains (1) a README file with information on the various files, (2) three csv files describing the metadata collected for each surface point location, plot and region registered with the WFSFA, (3) csv files with metadata and contact information for each surface point location registered with the WFSFA, (4) a csv file with with metadata and contact information for plots, (5) a csv file with metadata for geographic regions and sub-regions within the watershed, (6) a compiled xlsx file with all the data and metadata which can be opened in Microsoft Excel, (7) a kml map of the locations plotted in the watershed which can be opened in Google Earth, (8) a jpeg image of the kml map which can be viewed in any photo viewer, and (9) a zipped file with the registration templates used by the SFA team to collect location metadata. The zipped template file contains two csv files with the blank templates (point and plot), two csv files with instructions for filling out the location templates, and one compiled xlsx file with the instructions and blank templates together. Additionally, the templates in the xlsx include drop down validation for any controlled metadata fields. Persistent location identifiers (Location_ID) are determined by the WFSFA data management team and are used to track data and samples across locations. Dataset uses: This location metadata is used to update the Watershed SFA’s publicly accessible Field Information Portal (an interactive field sampling metadata exploration tool; https://wfsfa-data.lbl.gov/watershed/), the kml map file included in this dataset, and other data management tools internal to the Watershed SFA team. Version Information: The latest version of this dataset publication is version 3.0. The latest version contains a breaking change to the Location Map (EastRiverCommunityObservatory_Map_v3_0_20220613.kml), If you had previously downloaded the map file prior to version 3.0, it will no longer work. Use the updated Location Map (EastRiverCommunityObservatory_Map_v3_0_20220613.kml) in this version of the dataset. This version also contains a total of 51 new point locations, 8 new plot locations, and 1 new geographic region. Additionally, it corrects inconsistencies in existing metadata. Refer to methods for further details on the version history. This dataset will be updated on a periodic basis with new measurement location information. Researchers interested in having their East River measurement locations added in this list should reach out to the WFSFA data management team at [e-mail].

本数据集包含标识符、元数据，以及美国科罗拉多河上游流域东河社区观测站的野外测量点位地图。本数据集为3.0版本，替代此前的2.0版本，旧版已不再适用（版本间变更详情见下文）。

数据集说明：东河是流域功能科学重点区域（Watershed Function Scientific Focus Area, WFSFA）与落基山生物实验室的核心野外研究站点。来自多家机构的研究人员与WFSFA合作，在东河流域开展了涵盖水文、生物地球化学、气候、植被、地质、遥感与模型模拟等多领域的多样化数据采集工作。因此，本数据集旨在构建野外点位与仪器设备清单，为东河流域的野外活动提供信息支撑，并协调不同点位、研究者与机构间的跨主体数据收集工作。

本数据集包含以下内容：(1) 一份README文件，内含各文件的说明信息；(2) 三个CSV文件，用于描述WFSFA登记的所有地表点位、样地与区域的元数据；(3) 若干CSV文件，包含WFSFA登记的各地表点位的元数据与联系信息；(4) 一个CSV文件，包含样地的元数据与联系信息；(5) 一个CSV文件，包含流域内地理区域与子区域的元数据；(6) 一份整合后的XLSX文件，包含全部数据与元数据，可使用Microsoft Excel打开；(7) 一份流域点位KML地图文件，可在Google Earth中打开；(8) 一张KML地图的JPEG图像，可通过任意图片查看器浏览；(9) 一个压缩包，内含WFSFA团队用于采集点位元数据的登记模板。该压缩包包含两份空白模板CSV文件（点位与样地）、两份点位模板填写说明CSV文件，以及一份整合了说明与空白模板的XLSX文件。此外，XLSX模板中的受控元数据字段已设置下拉验证选项。持久化点位标识符（Location_ID）由WFSFA数据管理团队制定，用于跨点位追踪数据与样品。

数据集用途：本点位元数据用于更新WFSFA的公开野外信息门户（交互式野外采样元数据探索工具，https://wfsfa-data.lbl.gov/watershed/）、本数据集附带的KML地图文件，以及WFSFA团队内部的其他数据管理工具。

版本信息：本数据集的最新发布版本为3.0。本版本对点位地图（EastRiverCommunityObservatory_Map_v3_0_20220613.kml）进行了突破性变更，若您此前下载过3.0版本之前的地图文件，将无法继续使用，请使用本数据集附带的更新版点位地图（EastRiverCommunityObservatory_Map_v3_0_20220613.kml）。本版本新增了51个点位、8个样地与1个地理区域，同时修正了现有元数据中的不一致问题。有关版本历史的更多详情，请参阅方法部分。本数据集将定期更新，新增测量点位信息。若研究者希望将其在东河流域的测量点位加入本清单，请联系WFSFA数据管理团队，邮箱为[e-mail]。
