Loc_Table CSVs

  • Data located on Github.

  • Filename Structure: 4-digit Cruise#, 3-digit acoustic ID#, SignalTypeProcessed (P1=both, P2=clicks, P3=whistles), Loc_table.csv. Example: 1705279P1_Loc_table.csv (HICEAS17-Lasker AC279 both)

  • Rows: Localization data for each TRACE.

  • Columns:

    Column Name Description Use for Detection Function
    TrackID_1 (1,2,3,etc) Track ID number used for the TRACE YES
    Loc_start_time Start time from 1st track in the TRACE sequence (Time adjusted if track started at a bearing angle <30 degrees) YES
    Loc_end_time End time from last track in the TRACE sequence (Time adjusted if track ended at a bearing angle >120 degrees) YES
    Loc_beam_time Time when the TRACE crosses the beam (87 to 93 degrees). NOTE: Localizations that show up with this date time (14-Jul-1916 00:00:00) in the end Loc_table do not have a beam time. YES
    Loc_m_1 X: Localization estimate in Cartesian coordinates with respect to start of boat track (meters)
    Loc_m_2 Y: Localization estimate in Cartesian coordinates with respect to start of boat track (meters)
    Loc_m_min_1 min of Loc_m_1
    Loc_m_min_2 min of Loc_m_2
    Loc_m_max_1 max of Loc_m_1
    Loc_m_max_2 max of Loc_m_2
    Loc_LatLong_1 LAT: Localization estimate as latitude and longitude (decimal degrees). Note that all animals are plotted on a single side of the trackline.
    Loc_LatLong_2 LON: Localization estimate as latitude and longitude (decimal degrees). Note that all animals are plotted on a single side of the trackline.
    Loc_m_dilated_1 X: Localization estimate from dilated AS in Cartesian coordinates with respect to start of boat track (meters)
    Loc_m_dilated_2 Y: Localization estimate from dilated AS in Cartesian coordinates with respect to start of boat track (meters)
    Loc_m_dilated_min_1 min of Loc_m_dilated_1
    Loc_m_dilated_min_2 min of Loc_m_dilated_2
    Loc_m_dilated_max_1 max of Loc_m_dilated_1
    Loc_m_dilated_max_2 max of Loc_m_dilated_2
    Loc_LatLong_dilated_1 LAT: Localization estimate from dilated AS as latitude and longitude (decimal degrees). Note that all animals are plotted on a single side of the trackline.
    Loc_LatLong_dilated_2 LON: Localization estimate from dilated AS as latitude and longitude (decimal degrees). Note that all animals are plotted on a single side of the trackline.
    distance_m Perpendicular distance from localization estimate (Loc_m) to the array (meters)
    distance_m_minmax_1 min of distance_m
    distance_m_minmax_2 max of distance_m
    distance_m_dilated Perpendicular distance from localization estimate from dilated AS (Loc_m_dilated) to the array (meters). Currently calibrated for false killer whales (swim speed, etc.) YES
    distance_m_dilated_minmax_1 min of distance_m_dilated YES
    distance_m_dilated_minmax_2 max of distance_m_dilated YES
