Date/time (local)LatitudeLongitudeNotes
06/01/25 02:04:1449.6742-64.9335Downsweep in P16, its concavity difficult to discern.
06/01/25 02:19:1449.6742-64.9335Short, concave-up downsweep in P6.
06/01/25 02:34:1449.6743-64.9334Short, concave-up downsweep in P12.
06/01/25 04:04:1449.6727-64.9358Possible short-duration downsweeps in P1 & 2 (no concavity).
06/01/25 04:49:1449.6730-64.9358Possible short-duration downsweeps in P3, 4, & 6 (potentially concave-up).
06/01/25 05:49:1449.6735-64.9359Possible short-duration downsweep in P14 (potentially concave-up).
06/01/25 06:34:1449.6738-64.9359Possible short-duration downsweep in P15 (potentially concave-up).
06/01/25 07:19:1449.6741-64.9359Possible BW D calls in P1 (slightly concave-down) and P3 (concave-up), although the concavity of the call in P1 is difficult to confirm, so this period has been scored conservatively (PD).
06/01/25 10:19:1449.6755-64.9361Concave-up downsweep in P8; although it is classified as SW call type 1, there is no additional evidence of SW presence.
06/01/25 11:29:4149.6684-64.9694Possible RW upsweep in P9, although it is low amplitude, unclassified, and the glider was approaching the surface, so there is a good chance this is attributable to background noise, rather than a genuine call.
06/01/25 14:34:1449.6689-64.9691Possible concave-up downsweep in P8, although it has an inconsistent amplitude and jagged pitch track.
06/01/25 14:49:1449.6689-64.9691Possible downsweeps in P3 & 14, although their short durations make it difficult to determine concavity.
06/01/25 15:04:1449.6690-64.9691Possible downsweeps in P3-5, although their short durations make it difficult to determine concavity.
06/01/25 18:19:1449.6695-64.9687Possible biological upsweep in P16, although it is unclassified, short in duration, unshapely, and surrounded by other potential background noise.
06/01/25 19:31:4249.6671-64.9857Three consecutively classified FW pulses in P11 with an INI = 11 seconds; however, these are not in isolation but are in proximity to potential background noise.
06/01/25 19:49:1449.6653-64.9972Possible downsweeps in P9 & 13, although their short durations make it difficult to determine concavity.
06/01/25 20:19:1449.6654-64.9972Possible downsweep in P13 (low amplitude), although its short duration makes it difficult to determine concavity.
06/01/25 20:34:1449.6654-64.9972Possible downsweeps in 2, 4, & 7, although their short durations make it difficult to determine concavity; although the call in P7 is classified as SW call type 1, there is no convincing evidence of SW presence.
06/01/25 20:49:1449.6654-64.9972Possible HW song throughout the period, but most of the pitch tracks contain large artifacts, there are no convincing tonal/frequency-modulated calls to indicate definitively that these are genuine calls rather than background noise, and there is no obvious repetition of pitch tracks.
06/01/25 21:34:1449.6655-64.9971Downsweep in P11 (no discernible concavity).
06/01/25 21:49:1449.6655-64.9971Possible downsweeps in P7, 11, & 12, although their short durations make it difficult to determine concavity; the call in P7 is classified as SW call type 1, but there is no additional evidence of SW presence.
06/01/25 22:19:1449.6655-64.9970Concave-up downsweep in P8; although classified as SW call type 1, there is no additional evidence of SW presence.
