Article Synopsis
- Climate change is altering habitats in the Arctic Ocean, affecting migrating baleen whales like blue and fin whales, leading to changes in their range and presence in Arctic waters.
- A study using passive acoustic monitoring in Fram Strait from 2012 to 2021 reveals that blue whales are primarily present from July to October, with some winter activity, while fin whales peak in mid-summer to autumn with some winter and sporadic spring presence.
- Environmental factors such as zooplankton mass and sea surface temperature influence the acoustic presence of blue and fin whales, with no significant trends in the timing of their presence over the years, indicating Fram Strait is an important feeding ground for these species.
This study investigates the relevance of the Elephant Island (EI) region for Southern Hemisphere fin whales () in their annual life cycle. We collected 3 years of passive acoustic recordings (January 2013 to February 2016) northwest of EI to calculate time series of fin whale acoustic indices, daily acoustic occurrence, spectrograms, as well as the abundance of their 20 Hz pulses. Acoustic backscatter strength, sea ice concentration and chlorophyll-a composites provided concurrent environmental information for graphic comparisons.
