Outliers have the value TRUE. units: none entity described: event THIS DATASET: A duplicate filter was run in Movebank in April 2020 using key attributes tag ID and timestamp. animal ID: An individual identifier for the animal, provided by the data owner. If the data owner does not provide an Animal ID, an internal Movebank animal identifier is sometimes shown. example: 91876A, Gary units: none entity described: individual same as: individual local identifier animal taxon: The scientific name of the species on which the tag was deployed, as defined by the Integrated Taxonomic Information System (ITIS, www.itis.gov). If the species name can not be provided, this should be the lowest level taxonomic rank that can be determined and that is used in the ITIS taxonomy. Additional information can be provided using the term 'taxon detail'. example: Buteo swainsoni format: controlled list entity described: individual same as: individual taxon canonical name Argos LC: The location class retrieved from Argos (0, 1, 2, 3, A, B, Z), Argos diagnostic data (definition from Argos User's Manual 2011). format: controlled list units: none entity described: event attachment type: The way a tag is attached to an animal. Values are chosen from a controlled list: collar = The tag is attached by a collar around the animal's neck glue = The tag is attached to the animal using glue harness = The tag is attached to the animal using a harness implant = The tag is placed under the skin of the animal tape = The tag is attached to the animal using tape other = user specified format: controlled list entity described: deployment deploy off timestamp: The timestamp when the tag deployment ended. example: 2009-10-01 12:00:00.000 format: yyyy-MM-dd HH:mm:ss.SSS units: UTC or GPS time entity described: deployment same as: deploy off date deploy on latitude: The geographic latitude of the location where the animal was released (intended primarily for instances in which the animal release and tag retrieval locations have higher accuracy than those derived from sensor data). example: 27.3516 units: decimal degrees, WGS84 reference system entity described: deployment deploy on longitude: The geographic longitude of the location where the animal was released (intended primarily for instances in which the animal release and tag retrieval locations have higher accuracy than those derived from sensor data). example: -97.3321 units: decimal degrees, WGS84 reference system entity described: deployment deploy on timestamp: The timestamp when the tag deployment started. example: 2008-08-30 18:00:00.000 format: yyyy-MM-dd HH:mm:ss.SSS units: UTC or GPS time entity described: deployment same as: deploy on date deployment comments: Additional information about the tag deployment that is not described by other reference data terms. example: body length 154 cm; condition good units: none entity described: deployment deployment ID: A unique identifier for the deployment of a tag on animal, provided by the data owner. If the data owner does not provide a Deployment ID, an internal Movebank deployment identifier may sometimes be shown. example: Jane-Tag42 units: none entity described: deployment duty cycle: Remarks associated with the duty cycle of a tag during the deployment, describing the times it is on/off and the frequency at which it transmits or records data. Units and time zones should be defined in the remarks. example: 15-min fixes from 8:00-18:00 local time (0:00-10:00 UTC) units: not defined entity described: deployment event ID: An identifier for the set of values associated with each event, i.e. sensor measurement. A unique event ID is assigned to every time-location or other time-measurement record in Movebank. If multiple measurements are included within a single row of a data file, they will share an event ID. If users import the same sensor measurement to Movebank multiple times, a separate event ID will be assigned to each. example: 6340565 units: none entity described: event location lat: The geographic longitude of the location as estimated by the sensor. Positive values are east of the Greenwich Meridian, negative values are west of it. example: -41.0982423 units: decimal degrees, WGS84 reference system entity described: event location long: The geographic longitude of the location as estimated by the sensor. Positive values are east of the Greenwich Meridian, negative values are west of it. example: -121.1761111 units: decimal degrees, WGS84 reference system entity described: event manipulation type: The way in which the animal was manipulated during the deployment. Values are chosen from a controlled list: confined = The animal's movement was restricted to within a defined area none = The animal received no treatment other than the tag attachment relocated = The animal was released from a site other than the one at which it was captured manipulated other = The animal was manipulated in some other way, such as a physiological manipulation. format: controlled list entity described: deployment manually marked outlier: Identifies events flagged manually as outliers, typically using the Event Editor in Movebank, and may also include outliers identified using other methods. Outliers have the value TRUE. units: none entity described: event sensor type: The type of sensor with which data were collected. All sensors are associated with a tag id, and tags can contain multiple sensor types. Each event record in Movebank is assigned one sensor type. If values from multiple sensors are reported in a single event, the primary sensor is used. Values are chosen from a controlled list: acceleration = The sensor collects acceleration data accessory measurements = The sensor collects accessory measurements, such as battery voltage Argos Doppler shift = The sensor uses Argos Doppler shift to determine position barometer = The sensor records air or water pressure bird ring = The animal is identified by a band or ring that has a unique identifier GPS = The sensor uses GPS to determine location magnetometer = The sensor records the magnetic field natural mark = The animal is identified by a unique natural marking orientation = Quaternion components describing the orientation of the tag are derived from accelerometer and gyroscope measurements radio transmitter = The sensor is a classical radio transmitter solar geolocator = The sensor collects light levels, which are used to determine position (for processed locations) solar geolocator raw = The sensor collects light levels, which are used to determine position (for raw light-level measurements) solar geolocator twilight = The sensor collects light levels, which are used to determine position (for twilights calculated from light-level measurements). format: controlled list entity described: event study name: The name of the study in Movebank. example: Coyotes, Kays and Bogan, Albany NY units: none entity described: study, event study site: A location such as the deployment site or colony, or a location-related group such as the herd or pack name. example: Pickerel Island North units: none entity described: deployment tag ID: A unique identifier for the tag, provided by the data owner. If the data owner does not provide a tag ID, an internal Movebank tag identifier may sometimes be shown. example: 2342 units: none entity described: tag same as: tag local identifier timestamp: The date and time corresponding to a sensor measurement or an estimate derived from sensor measurements. example: 2008-08-14 18:31:00.000 format: yyyy-MM-dd HH:mm:ss.SSS units: UTC or GPS time entity described: event visible: Determines whether an event is visible on the Movebank map. Values are calculated automatically, with TRUE indicating the event has not been flagged as an outlier by 'algorithm marked outlier', 'import marked outlier' or 'manually marked outlier', or that the user has overridden the results of these outlier attributes using 'manually marked valid' = TRUE. Allowed values are TRUE or FALSE. units: none entity described: event ----------- More Information For more information about this repository, see www.movebank.org/cms/movebank-content/data-repository, the FAQ at www.movebank.org/cms/movebank-content/data-repository-faq, or contact us at support@movebank.org.
