Description:

Abstract:

This metadata document describes the data contained in the "processedData" folder of this data package. This data package contains all data collected by the Argos System from 167 satellite transmitters attached to Common Eiders on their breeding range in arctic and western Alaska, 2000-2008. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data. Three Comma Separate Value (CSV) tables are included in the "processedData" folder of this data package: 1) the "diag_filteredLocations" table contains one record for every Argos location estimate collected, accompanied by a binary flag that denotes an algorithm's plausibility check (based on distance, turning angle, and rate thresholds). Each record also includes a 'Tracking_Status' variable that denotes whether the location was collected from a live animal, a dead animal, or shed transmitter, 2) the "decodedSensor" table contains decoded sensor data such as the transmitter's temperature, battery voltage, and motion (activity), and 3) the "deploymentAttributes" table contains one record for each transmitter deployment in a CSV formatted table. The deployment attributes file contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and a variety of variables describing the animal and transmitter. This table is identical to the "deploymentAttributes" table in the "rawData" folder of this data package.

Purpose:

These data were collected to better understand the timing and patterns of migratory movement of Common Eiders between breeding areas in Alaska and wintering areas along the north Pacific and Bering Sea coast of North America and Asia.

Supplemental_Information:

Data users are advised to review the README and metadata documents to ensure proper use of the 'Deployment_Fate' and 'Tracking_Status' variables. Misuse or disregard of these variables could result in location data from dead animals or detached transmitters being incorrectly analyzed as data representing a live animal. Also note that, outlier values are not uncommon in the sensor data due to transmission parity errors introduced during satellite communications and no checksum values were embedded in the sensor messages to help screen for parity errors.

The deployment attributes and processed tracking data in this data package are also publicly available in Movebank (www.movebank.org) under a study entitled: "commonEider_USGS_ASC_argos".

Analytical_Tool:

Analytical_Tool_Description:

Implausible Argos location estimates were flagged using the Douglas Argos-filter (DAF). DAF is an ad-hoc algorithm that identifies implausible Argos location estimates based on user-defined thresholds which allows the algorithm's performance to be tuned to species' movement, behaviors, and study objectives. Key thresholds define: 1) the distance within which sequential location estimates are retained by virtue of self-validating spatial redundancy, 2) a maximum rate of movement, and 3) the acuity of tight turning angles which are characteristically created by location estimates with large errors. The actual thresholds that were applied are detailed in the "Douglas-Argos Filter" Process Step of this metadata record and in the README file included with the data package.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Most attributes associated with the location data were acquired directly from the Argos System. Accuracy of the location filtering flag ('Location_DAF_Filter') is vulnerable to omission/commission errors as described in Douglas et al 2012. Accuracy of the 'Deployment_Fate' and 'Tracking_Status' variables is sensitive to the type of data available; for example, temperature data from implanted transmitters provide a definitive measure of animal mortality, while an integrated interpretation of sensor and movement data is required to determine whether externally attached transmitters show evidence of mortality or transmitter detachment. Transmission parity errors (misrepresentations of 1's and 0's introduced during earth-to-satellite communication) occur and should be expected when analyzing sensor data. No checksum values were embedded in the sensor messages to help screen for parity errors. Users are advised to interpret just the dominant patterns among the sensor data values and be skeptical of any values that appear to be outliers.

Logical_Consistency_Report:

All values are consistent with animal tracking data obtained by the Argos System. Files included in this data package may contain data obtained post-mortality or post-detachment. For analyses of live free-ranging animals, care must be exercised to use only those data records collected on or before the deployment end time stamp (provided in the "deploymentAttributes" table included with the data package). Data users are additionally advised that outlier values are not uncommon in decoded sensor data due to transmission parity errors introduced during satellite communications. Blank cells indicate attributes that were not collected or not determined.

Completeness_Report:

These data comprise the complete set of transmissions collected by the Argos satellite system from satellite transmitters described in the "deploymentAttributes" table. Temporal gaps in the tracking data time series are intrinsic to the Argos System due to the intermittent coverage of orbiting satellites. Additional temporal gaps are often intentionally introduced by transmitting intermittently to conserve power (i.e., duty cycles). Unintentional data gaps can be introduced by many factors such as insufficient power, antenna damage, or animal behavior and habitat. The filtering of implausible location estimates also contributes to temporal gaps.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

'Standard Quality' location estimates determined by the Argos System (locations classes 3, 2 and 1) have a 1-sigma (68% of locations) accuracy range of 250-1500 m (see Argos Manuals - included with this data package; Douglas et al 2012 and references therein).

Methodology:

Methodology_Type: Lab
Methodology_Description:

Transmissions from satellite transmitters were received by the Argos satellite system and relayed to ground based processing centers. Location estimates were derived by Argos based on Doppler principles. Final data were disseminated to the U.S. Geological Survey as text files containing location and raw (coded) sensor data.

Describes the use of the "Douglas Argos Filter" (DAF) for flagging implausible Argos locations.

Process_Step:

Process_Description:

Data Collection. Argos raw data in both "DS" and "DIAG" legacy formats were extracted from monthly datasets provided by Service Argos (a.k.a. CLS America or Woods Hole Group) on CD-ROM. Beginning in July 2009, both DS and DIAG data were obtained from Service Argos on CD-ROM in tabular format as Comma Separated Value (CSV) files. The tabular files contain all information reported in the Argos legacy file formats. The tabular DIAG files also include variables describing the Argos error ellipse (beginning in July 2009). Tabular DIAG data files before July 2009 (if applicable) were reformatted directly from the legacy DIAG files, and hence do not contain the error ellipse variables.

Process_Date: Unknown

Process_Description:

Data Flattening. The raw Argos tabular files have had additional attributes appended by the authors to each record (including 'Animal_ID', 'Animal_Species' and 'Tracking_Status').

Process_Date: Unknown

Process_Step:

Process_Description:

Determination of Deployment Fate and Tracking Status. Location and sensor data were examined for each record to assign the value of the 'Deployment_Fate' and 'Tracking_Status' variables. Details are described in the attribute definitions, below.

Process_Date: Unknown

Process_Step:

Process_Description:

Argos Location Algorithms. Argos uses one of two algorithms (Least Squares and Kalman Filter) to estimate location by regression fit of a Doppler curve obtained from the perceived (shifted) frequencies of transmissions obtained as the satellite flew over the satellite transmitter (i.e., approaching, then retreating). The Least Squares algorithm provides two different location estimates ('primary' and 'alternate'). The 'primary' estimate is assumed to better reflect the actual PTT location. However, in approximately 1-3% of cases, the 'alternate' location is more accurate.

The Kalman Filter algorithm (introduced by Argos in 2011) takes into account platform dynamics and the use of a bank of Kalman filters to calculate positions. The applied Kalman filtering is a 2-step process: 1) the filter predicts the next position and its estimated error based on the previous position and its estimated error with a movement model; and 2) the filter calculates the new position and its estimated error by updating the predicted position using frequency measurements acquired during the satellite pass. The Kalman filter provides two identical location estimates.

Note that the algorithm used for each PTT deployment is recorded in the "deploymentAttributes" table included with this data package.

Process_Date: Unknown

Process_Step:

Process_Description:

Douglas Argos-Filter. Implausible location estimates were flagged using the Douglas Argos-filter (DAF) as implemented in Movebank. DAF is an ad hoc algorithm that identifies implausible Argos location estimates based on user-defined thresholds which allows the algorithm's performance to be tuned to species' movement, behaviors, and study objectives. Key thresholds define: 1) the distance within which sequential location estimates are retained by virtue of self-validating spatial redundancy, 2) a maximum rate of movement, and 3) the acuity of tight turning angles which are characteristically created by location estimates with large errors.

Definitions of the DAF parameters can be found in the filtering help pages at Movebank.com and Douglas et al 2012. The user-defined DAF parameters applied to these data were:

Filter Method = Best Hybrid; keep_lc=1; maxredun=10; offset by one second=True; keeplast=disabled; skiploc=disabled; minrate=80; r_only=disabled; ratecoef=15; xmigrate=2; xoverrun=1.5; xdirect=20; xangle=150; xpercent=20; testp_0a=2; testp_bz=3; Best of Day filter=disabled; pickday=disabled

Each animal's track was visually examined to assess the algorithm-derived filtering decisions, and manually edited if warranted.

Process_Date: Unknown

Process_Step:

Process_Description:

Raw sensor data are encoded for transmission. The specifics of encoding vary with transmitter manufacturer and model. We decoded raw (coded) sensor values, received from Service Argos, following procedures prescribed by transmitter manufactures.

Sensor data from Microwave Telemetry Inc (MTI) satellite transmitters were decoded by utilizing the decode equations provided in the MTI Battery PTT-100 Manual.

Enumerated_Domain_Value_Definition:

For exterior satellite transmitter attachments; a distinct drop in the transmitter's temperature sensor data suggesting the animal's body temperature is no longer contributing to elevating temperature above ambient conditions (unreliable in warm climates). For externally attached transmitters, this classification implies either animal mortality or detachment in a relatively cool or cold environment where a distinct temperature drop can be realized between the warmer than ambient temperatures that typically recorded from live animals because their body heat is partially conducted into the transmitter.

Entity_Type_Label: commonEider_USGS_ASC_argos_diag_filteredLocations
Entity_Type_Definition:

This table contains all records from the raw Argos DIAG tabular data included with this package, except that records with missing locations have been removed. Additionally, three variables were added after processing with the Douglas Argos Filter (DAF) algorithm (Douglas et al 2012). The three variables are: 1 & 2) 'Latitude' & 'Longitude', the algorithm's choice between the primary and alternate latitudes and longitudes (Argos Solution 1 and Solution 2) based on minimizing the animal's cumulative distance moved, and 3) 'Location_DAF_Filter', a binary flag indicating whether the location is plausible (=0)or implausible (=1). For records dated after the 'Deployment_End_Timestamp' (i.e., locations after an animal has died or a transmitter has been shed), location coordinates are presented in the 'Lat_ShedDead' and 'Lon_ShedDead' columns and no values are provided for 'Latitude' and 'Longitude'. All data are presented in a Comma Separated Value (CSV) formatted table.

Attribute_Label: Location_ErrorGDOP
Attribute_Definition:

Geometric Dilution of Precision. A measure of the effect of the geometry of the satellite transmitter's configuration on the accuracy of the location estimate. The actual location accuracy depends on both the GDOP value and the quality of the transmitter’s frequency stability. Generally, a smaller GDOP value yields a more accurate position. Values of zero (0) should be treated as missing data.

Attribute_Label: Location_IndexQuality
Attribute_Definition:

A "Quality Indicator" from Argos. A composite of two single digits, each of which denotes a categorical variable describing parameters that Argos considers when assigning the Location_Class to the location estimate. The parameters describe long-, mid-, and short-term frequency shifts in the received transmissions. The first digit indicates the residual error on the frequency calculation. The second digit indicates transmitter oscillator frequency drift between two satellite overpasses. Single digit values imply a zero for the first digit.

This file contains all decoded sensor data derived from the raw Argos DS data included with this package. When available, each record contains up to three decoded variables (temperature, voltage, and activity) as well as identifying attributes of the satellite transmitter (PTT) and animal. To minimize decoding diagnostic messages that were embedded into every 4th transmission from the Microwave Telemetry PTTs used in this study, decoded values were calculated from raw data and written to this file only if raw sensor values were not indicative of a diagnostic message. Presented in a Comma Separated Value (CSV) formatted table.

Overview_Description:

Entity_and_Attribute_Overview:

The processData package includes 3 Comma Separate Value (CSV) formatted tables:

(1) "commonEider_USGS_ASC_argos_diag_filteredLocations.csv" contains one record for every location estimate collected, accompanied by a binary flag that denotes an algorithm's plausibility check. Each record also includes a 'Tracking_Status' variable that denotes whether the location was collected from a live animal, a dead animal, or shed transmitter.

(2) "commonEider_USGS_ASC_argos_decodedSensor.csv" contains decoded sensor data such as a transmitter's temperature, battery voltage, and motion (activity).

(3) "commonEider_USGS_ASC_argos_deploymentAttributes.csv" contains one record for each transmitter deployment. The deployment attributes table contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and variables describing the animal and transmitter.
