07/14/25 14:28:40Possibly detected48.8046-62.8626Low amplitude concave-down downsweep in P16, possible downsweeps in P8 and P14. Marking possibly detected instead of detected since all calls are low amplitude and not all contain convincing evidence of a true call.
07/14/25 14:43:40Detected48.8046-62.8626Arch call in P12, and other calls in P1, P2, P5, P6, P8 to support blue whale detection. P8 concave down, P6 classified as HW17 and P5 classified as SW3. Possible blue whale A call in P11.
07/14/25 15:13:40Detected48.8046-62.8627Concave down D calls in P4 and P7. Other D calls present for blue whale detection (P3, 4, 5, 6, 7, 8) some classified as SW or HW17.
07/14/25 15:43:40Detected48.8046-62.8627Concave down D call in P2, not super convincing in itself due to low amplitude, but other calls have slight downward concavity as well (P4, P10) for blue whale detection. BW classification could be a faint call, but only a speck was pitch- tracked, so not useable in decision.
07/14/25 16:13:40Detected48.8046-62.8627Low amplitude concave-down D call in P5. Other calls in P2-6, P8-13, P15-16. 5 classified as HW17 with a concave up shape, one classified as SW3, no concavity. Despite many calls having no concavity/concave-up concavity, many are long in duration and have a shallower slope more characteristic of blue whale calls, helping to increase confidence in blue whale detection.
07/14/25 16:28:40Detected48.8046-62.86272 concave down D calls in P4 and P5. Other D calls present in P1, 2, 4, 12. Blue whale detected.
07/14/25 16:58:40Detected48.8046-62.8627BW34 classification not centered on concave-down call in P1, so uncertain about using the classification for a detection, but regardless the call is concave down and there are other D calls in the tally period (P1, P2, P4, P5, P9)to be able to score BW detected.
07/14/25 18:28:40Detected48.8046-62.8627Low amplitude arch call in P7. D call in P9. Using the 2+ calls with one concave down, in this case the arch call, protocol to mark blue whale detected.
07/14/25 18:43:40Detected48.8046-62.8627Blue whale call classified as call type 33 in P12. Call has very slight downward concavity, but nice, long shape, blue whale detected. Additional short downsweep in P6, classified as HW17.
