Worldwide Soundscapes project meta-data

The Worldwide Soundscapes project is a global, open inventory of spatio-temporally replicated passive acoustic monitoring meta-datasets (i.e. meta-data collections). This Zenodo entry comprises the data tables that constitute its (meta-)database, as well as their description. The overview of all sampling sites can be found on the corresponding project on ecoSound-web, as well as a demonstration collection containing selected recordings. The audio recording criteria justifying inclusion into the meta-database are: Stationary (no transects, towed sensors or microphones mounted on cars) Passive (unattended, no human disturbance by the recordist) Ambient (no directional microphone or triggered recordings) Spatially and/or temporally replicated (i.e. multiple sites sampled at the same time and/or multiple days - covering the same daytime - sampled at the same site) The individual columns of the provided data tables are described in the following. Data tables are linked through primary keys; joining them will result in a database. The data shared here only includes validated collections. Changes from version 1.0.0 audio data moved to deployments table. datasets are called collections. Lookup fields and some collection table fields removed. collections collection_id: unique integer, primary key name: name of the dataset. if it is repeated, incremental integers should be used in the "subset" column to differentiate them. ecoSound-web_link: link of validated collections that were uploaded to ecoSound-web primary_contributors: full names of people deemed corresponding contributors who are responsible for the dataset secondary_contributors: full names of people who are not primary contributors but who have significantly contributed to the dataset, and who could be contacted for in-depth analyses date_added: when the datased was added (YYYY-MM-DD) URL_open_recordings: internet link of openly-available recordings from this collection URL_project: internet link for further information about the corresponding project DOI_publication: DOIs of corresponding publications core_realm_IUCN: The main, core realm of the dataset medium: the physical medium the microphone is situated in protected_area: whether the sampling sites were situated in protected areas or not, or only some. boolean locality: optional free text about the locality spatial_selection: spatial selection criteria that were used to determine in which locations to record sound (ecotone, elevated spot, etc.) - any deviations from randomness temporal_exclusion: environmental exclusion criteria that were used to determine which recording days or times to discard freshwater_recordist_position: position of the recordist relative to the microphone during sampling (only for freshwater) contributor_comments: free-text field for comments by the primary contributors collections-sites dataset_ID: primary key of collections table site_ID: primary key of sites table sites site_ID: unique integer, primary key site_name: name or code of sampling site as used in respective projects latitude_numeric: site's numeric degrees of latitude longitude_numeric: site's numeric degrees of longitude blurred_coordinates: whether latitude and longitude coordinates are inaccurate, boolean. Coordinates may be blurred with random offsets, rounding, snapping, etc. Indicate the blurring method inside the comments field topography_m: vertical position of the microphone relative to the sea level. for sites on land: elevation. For marine sites: depth (negative). in meters. Only indicate if the values were measured by the collaborator. freshwater_depth_m: microphone depth, only used for sites inside freshwater bodies that also have an elevation value above the sea level realm: Ecosystem type according to IUCN GET https://global-ecosystems.org/ biome: Ecosystem type according to IUCN GET https://global-ecosystems.org/ functional_group: Ecosystem type according to IUCN GET https://global-ecosystems.org/ contributor_comments: free text field for contributor comments deployments dataset_ID: primary key of datasets table dataset_name: lookup field deployment: use identical subscript letters to denote rows that belong to the same deployment. For instance, you may use different operation times and schedules for different target taxa within one deployment. start_date_min: earliest date of deployment start, double-click cell to get date-picker start_date_max: latest date of deployment start, if applicable (only used when recorders were deployed over several days), double-click cell to get date-picker start_time_mixed: deployment start local time, either in HH:MM format or a choice of solar daytimes (sunrise, sunset, noon, midnight). Corresponds to the recording start time for continuous recording deployments. If multiple start times were used, you should mention the latest start time (corresponds to the earliest daytime from which all recorders are active). If applicable, positive or negative offsets from solar times can be mentioned (For example: if data are collected one hour before sunrise, this will be "sunrise-60") permanent: is the deployment permanent (in which case it would be ongoing and the end date or duration would be unknown)? variable_duration_days: is the duration of the deployment variable? in days duration_days: deployment duration per recorder (use the minimum if variable) end_date_min: earliest date of deployment end, only needed if duration is variable, double-click cell to get date-picker end_date_max: latest date of deployment end, only needed if duration is variable, double-click cell to get date-picker end_time_mixed: deployment end local time, either in HH:MM format or a choice of solar daytimes (sunrise, sunset, noon, midnight). Corresponds to the recording end time for continuous recording deployments. recording_time: does the recording last from the deployment start time to the end time (continuous) or at scheduled daily intervals (scheduled)? Note: we consider recordings with duty cycles to be continuous. operation_start_time_mixed: scheduled recording start local time, either in HH:MM format or a choice of solar daytimes (sunrise, sunset, noon, midnight). If applicable, positive or negative offsets from solar times can be mentioned (For example: if data are collected one hour before sunrise, this will be "sunrise-60") operation_duration_minutes: duration of operation in minutes, if constant operation_end_time_mixed: scheduled recording end local time, either in HH:MM format or a choice of solar daytimes (sunrise, sunset, noon, midnight). If applicable, positive or negative offsets from solar times can be mentioned (For example: if data are collected one hour before sunrise, this will be "sunrise-60") duty_cycle_minutes: duty cycle of the recording (i.e. the fraction of minutes when it is recording), written as "recording(minutes)/period(minutes)". For example: "1/6" if the recorder is active for 1 minute and standing by for 5 minutes. sampling_frequency_kHz: only indicate the sampling frequency if it is variable within a particular dataset so that we need to code different frequencies for different deployments recorder subset_sites: If the deployment was not done in all the sites of the corresponding datasest, site IDs can be indicated here, separated by commas comments全球声景项目（Worldwide Soundscapes Project）是一项全球性的开源时空复现被动声学监测元数据集（即元数据集合）目录。本Zenodo存档条目包含构成其（元）数据库的数据表及其说明文档。所有采样点位的概览可在ecoSound-web平台的对应项目页面以及包含精选录音的演示集合（collection）中查看。 纳入本元数据集的音频录制需符合以下标准： 1. 固定式部署：无样带、拖曳式传感器或车载安装麦克风； 2. 被动式录制：无人值守，录制过程无人工干扰； 3. 环境声录制：未使用定向麦克风或触发式录制； 4. 时空复现性：同一时间采样多个点位，或同一点位在多个日期（覆盖相同时长段）开展采样。 下文将对所提供数据表的各列进行详细说明。各数据表通过主键相互关联，将其拼接后可形成完整数据库。本次共享的数据均为经过验证的集合（collection）。相较于1.0.0版本，本次更新作出以下调整：音频数据已迁移至部署（deployments）表；数据集统一称为集合（collection）；查找字段及部分集合表字段已移除。 ### 集合（collections）表 collection_id：唯一整数，主键，用于唯一标识集合 name：数据集名称。若存在重名数据集，需在“subset”列使用递增整数加以区分 ecoSound-web_link：已上传至ecoSound-web平台的验证后集合的链接 primary_contributors：被认定为对应贡献者的主要贡献人全名，对数据集负有直接责任 secondary_contributors：非主要贡献者但对数据集有显著贡献、可联系以开展深度分析的人员全名 date_added：数据集添加日期，格式为YYYY-MM-DD URL_open_recordings：本集合中公开可用录音的互联网链接 URL_project：对应项目的详细信息互联网链接 DOI_publication：对应出版物的数字对象唯一标识符（DOI） core_realm_IUCN：数据集的核心生态域，依据IUCN分类标准 medium：麦克风部署的物理介质类型 protected_area：采样点位是否位于保护区内，或仅部分点位位于保护区内，为布尔值类型 locality：关于采样点位的可选自由文本描述 spatial_selection：用于选定录音点位的空间筛选标准（如生态交错带、高地点位等），用于说明与随机采样的偏差情况 temporal_exclusion：用于剔除部分录制日期或时段的环境筛选标准 freshwater_recordist_position：采样时录制者相对于麦克风的位置，仅适用于淡水环境点位 contributor_comments：主要贡献者填写的自由文本备注字段 ### 集合-点位（collections-sites）表 dataset_ID：集合（collections）表的主键 site_ID：点位（sites）表的主键 ### 点位（sites）表 site_ID：唯一整数，主键，用于唯一标识采样点位 site_name：对应项目中使用的采样点位名称或代码 latitude_numeric：采样点位的数值型纬度，单位为度 longitude_numeric：采样点位的数值型经度，单位为度 blurred_coordinates：纬度与经度坐标是否已做模糊处理，为布尔值类型。坐标可通过随机偏移、取整、坐标对齐等方式模糊，需在备注字段中说明具体模糊方法 topography_m：麦克风相对于海平面的垂直位置。陆地点位为海拔高度，海洋点位为水深（负值），单位为米。仅当合作者实测获取该数值时填写 freshwater_depth_m：麦克风水深，仅适用于位于淡水水体且海拔高于海平面的点位 realm：依据IUCN全球生态系统分类标准（https://global-ecosystems.org/）的生态系统类型 biome：依据IUCN全球生态系统分类标准（https://global-ecosystems.org/）的生物群系类型 functional_group：依据IUCN全球生态系统分类标准（https://global-ecosystems.org/）的功能群类型 contributor_comments：贡献者填写的自由文本备注字段 ### 部署（deployments）表 dataset_ID：数据集（datasets）表的主键 dataset_name：查找字段 deployment：使用相同下标字母标记属于同一部署的行。例如，可在同一部署下针对不同目标类群设置不同的运行时段与计划 start_date_min：部署开始的最早日期，双击单元格可唤起日期选择器 start_date_max：部署开始的最晚日期，仅当记录仪分多日部署时需填写，双击单元格可唤起日期选择器 start_time_mixed：部署开始的本地时间，可采用HH:MM格式或选择太阳时段（日出、日落、正午、午夜）。对于连续录制部署，该值对应录制开始时间。若使用多个开始时间，需注明最晚开始时间（对应所有记录仪均激活的最早时段）。若适用，可注明相对于太阳时段的正负偏移量（例如：若数据在日出前1小时采集，则填写“sunrise-60”） permanent：部署是否为永久性部署，若为永久部署则当前仍在运行，结束日期或持续时长未知 variable_duration_days：部署持续时长是否可变，单位为天 duration_days：单台记录仪的部署持续时长，若时长可变则取最小值 end_date_min：部署结束的最早日期，仅当持续时长可变时需填写，双击单元格可唤起日期选择器 end_date_max：部署结束的最晚日期，仅当持续时长可变时需填写，双击单元格可唤起日期选择器 end_time_mixed：部署结束的本地时间，可采用HH:MM格式或选择太阳时段（日出、日落、正午、午夜）。对于连续录制部署，该值对应录制结束时间 recording_time：录制方式分为两种：从部署开始时间持续至结束时间（连续录制），或按每日固定时段录制（定时录制）。注：带有工作周期的录制视为连续录制 operation_start_time_mixed：计划的录制开始本地时间，可采用HH:MM格式或选择太阳时段（日出、日落、正午、午夜）。若适用，可注明相对于太阳时段的正负偏移量（例如：若数据在日出前1小时采集，则填写“sunrise-60”） operation_duration_minutes：恒定录制时长，单位为分钟 operation_end_time_mixed：计划的录制结束本地时间，可采用HH:MM格式或选择太阳时段（日出、日落、正午、午夜）。若适用，可注明相对于太阳时段的正负偏移量（例如：若数据在日出前1小时采集，则填写“sunrise-60”） duty_cycle_minutes：录制工作周期（即每分钟内的录制时长占比），格式为“录制时长(分钟)/周期时长(分钟)”。例如：若记录仪录制1分钟后待机5分钟，则填写“1/6” sampling_frequency_kHz：仅当特定数据集内采样频率存在差异，需为不同部署设置不同采样频率时，填写该字段 subset_sites：若部署未覆盖对应数据集的全部点位，可在此处以逗号分隔的形式列出相关点位ID comments：备注字段
