Dear colleagues,
My co-authors and I are pleased to announce that the following paper on 
fin whales in Svalbard Islands is now available online:

Papale, E., Pelagatti, M., Pedrazzi, G., Buscaino, G. Occurrence and 
patterns of fin whale songs reveal alternative migration strategies in 
Svalbard Islands, Norway. Sci Rep 13, 4436 (2023).

Abstract:
The Arctic marine environment is highly affected by global warming with 
notable changes in habitat conditions, which have great consequences on 
migrating species. For example, the timing of their migration can be 
altered leading to changes in their occurrence in suitable areas, which 
are critical for their survival. In this study, seven years of acoustic 
data were analysed in Svalbard Islands from 2014 to 2020, revealing that 
the occurrence of fin whales (Balaenoptera physalus) happened all 
year-round. The sea surface temperature recorded reveals conditions 
which could be favorable for these species to persist until the Polar 
Night. The occurrence of songs indicated that certain individuals did 
not undertake the migratory journey through the southern breeding 
grounds, possibly using the area for mating purposes. The analyses of 
the Inter-Note-Interval (INI) demonstrated that over the years songs 
with different patterns were found. This suggests that either the fin 
whales are able to switch their INI patterns or that populations with 
different INIs are visiting during the Winter. Therefore, this study 
unveils the undertaking of an alternative strategy to migration 
movements, and the possible potential origin of the fin whales 
overwintering in Svalbard.
