Data:
Single table of Argos satellite location data from 38 PTT satellite transmitters implanted in Red-throated Loons. Location data were filtered with the Douglas-Argos Filter (DAF; see description in metadata for details). Only locations deemed "plausible" by the DAF were included in this data set. Data were released in support of a published journal article:
 
McCloskey, S.E., Uher-Koch, B.D., Schmutz, J.A., Fondell. T.F. 2017. International migration patterns of Red-throated Loons (Gavia stellata) from four breeding populations in Alaska. PLoS One 13(1):e0189954  doi:10.1371/journal.pone.0189954

========================================

Version 2.0 posted online February 2020

Overview:
Expanded data to include records from additional birds, provided in both unfiltered (Raw) and filtered (Processed) forms.

Brought data up to USGS Alaska Science Center Wildlife Tracking Data Collection data standards, documentation standards and publication standards

-----------------------
Title Change: 
Tracking Data for Red-throated Loons (Gavia stellata)

-----------------------
Data Structure Changes:

Added 16 attributes:
Data_Release_DOI, Data_Release_Version, Animal_Species, Location_DAF_Filter, Location_ErrorRadius, Location_ErrorSemimajor, Location_ErrorSemiminor, Location_ErrorOrientation, Location_ErrorGDOP, Location_LI_Index, Location_QQ_Index, PTT_Program, Tracking_Status, Lat_ShedDead, Lon_ShedDead, Pass_Satellite_ID

Removed 8 attributes:
pick, duty, dutylocs, deltahr, jday, switch, deployed, herd

Renamed 16 attributes: 
animal=>Animal_ID, latitude=>Latitude, longitude=>Longitude, location_class=>Location_Class, nopc=>Location_NOPC, altitude=>Location_AssumedAltitude, lat_p=>Location_Lat_Solution_1, lon_p=>Location_Lon_Solution_1, lat_a=>Location_Lat_Solution_2, lon_a=>Location_Lon_Solution_2, ptt=>PTT_ID, nmess=>Pass_Messages_N, gt120=>Pass_Messages_gt120dB, apbest=>Pass_Messages_BestLeveldB, dur=>Pass_Duration, apfreq=>Pass_EstimatedFrequency

Collapsed multiple-attributes into single-attributes:
date, hour, minute, second=>Location_Timestamp_UTC
iqx, iqy=>Location_IndexQuality

Rearranged the attribute order

--------------------
Additions:

Appended location records deemed "implausible" by the DAF (distinguished by the attribute value in "Location_DAF_Filter")

Appended Argos satellite location data from an additional 14 Red-throated Loons

Added a Data_Release_Version" attribute. All records originally distributed in version 1.0 are coded "v01"; all other records are coded "v02"

Added file of deployment data for each bird and transmitter

Added file of satellite transmitter sensor data

Added files of raw Argos satellite tracking data (explained in Data Packaging below)

Added metadata for Raw data

Updated metadata for Processed data

-------------------
Data Packaging  
Data has been assembled into two data packages for distribution, one containing unfiltered Raw data, one containing filtered Processed data, each including documentation and supplemental files
