---|---|---|---|---|
08/26/20 08:30:58 | Possibly detected | 48.5392 | -62.1150 | Classified sei call is interspersed with other noise, is short and quiet BUT could it be part of a triplet? Blue whales also make triplets and these calls are not obviously separated by 3.5 sec (sei characteristic) so I am not confident it is a sei. Two other calls are not classified but are better shape and amplitude than the classified call. Note that there have been numerous visual sightings of blue whales but no sightings of sei whales in the GoSL this year despite record high levels of survey effort by multiple aircraft. |
08/26/20 19:15:58 | Possibly detected | 48.5124 | -62.0426 | |
08/26/20 19:45:58 | Possibly detected | 48.5161 | -62.0462 | Here is another period where it is ambiguous whether sei or blue whales are calling, or both. Many of these downsweeps are longer than sei, and there may be an arch-call in P6. Two of the calls are classified as sei whale call types, but these could be partial pitch tracks of longer blue whale downsweep calls. |
08/26/20 20:00:58 | Possibly detected | 48.5179 | -62.0480 | |
08/26/20 21:00:58 | Possibly detected | 48.5253 | -62.0553 | This period is really interesting because the downsweeps are short, loud and convex, which looks like a sei whale call. One is classified as a sei (call type 3). But there are also two longer downsweeps in P1 and P7 that are more characteristic of blue. |
