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 25 satellite transmitters attached to Surf Scoters on their winter ranges in southeast Alaska and Baja California, Mexico, 2005-2008. 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 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) the "decodedSensor" table contains decoded sensor data such as a 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 movements of Surf Scoters between wintering areas along the Pacific coast of North America and breeding areas in northwestern Canada and Alaska.
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: "surfScoter_USGS_ASC_argos".

Analytical_Tool_Description:
Implausible 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:
Location estimates determined by the Argos System have a 1-sigma (68% of locations) accuracy range of 250-1500 m (see Argos Manual 2008 - included with this data package; Douglas et al 2012 and references therein).
Lineage:
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.

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_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=130; r_only=disabled; ratecoef=25; xmigrate=2; xoverrun=300; xdirect=90; xangle=60; xpercent=200; testp_0a=1; testp_bz=1; Best of Day filter=disabled; pickday=disabled

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.

Entity_Type_Label: surfScoter_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_Class
Attribute_Definition:
Index of the accuracy of the location estimate; in decreasing order: 3,2,1,0,A,B,Z. The raw DIAG data from the Argos System provides two location estimates ('primary' and 'alternate'). Different algorithms have been used to estimate location. The Least Squares algorithm provides two different locations, with the 'primary' assumed to better reflect the actual PTT location. However, in approximately 1-3% of cases, the 'alternate' location is more accurate. For these processed data the DAF algorithm has been applied to rectify incorrect choices between the 'primary' and 'alternate' location estimate. 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.

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.

Overview_Description:
Entity_and_Attribute_Overview:
The processData package includes 3 Comma Separate Value (CSV) formatted tables:
(1) "surfScoter_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) "surfScoter_USGS_ASC_argos_decodedSensor.csv" contains decoded sensor data such as a transmitter's temperature, battery voltage, and motion (activity).
(3) "surfScoter_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.
