@hikingdude @TimKStanton I was lucky enough to see whales about 1000 nm north of Hawaii on a NOAA research cruise. I was so surprised all I could get out of my mouth was to point and stammer ... big ... big ... dolphins. Funny thing was I spotted them before the group on the cruise that was there specifically to spot them ... but in their defense, the whales popped up close to our ship an they were busy scanning the horizon and further out. I did the best I could with the camera I had at the time (April 2008). #Whales #NorthPacific #NOAA

[Wams et al.] Singers of the high Arctic; Seasonal acoustic presence of bowhead whales (Balaena mysticetus) around Svalbard, Norway nature.com/articles/s41598-025 🐋 #Cetaceans #MarineMammals #MarineLife #MarineBiology #Whales #Science

NatureSingers of the high Arctic; Seasonal acoustic presence of bowhead whales (Balaena mysticetus) around Svalbard, Norway - Scientific ReportsThe bowhead whale (Balaena mysticetus) is an Arctic endemic cetacean that spends its entire life in Arctic waters, living in tight association with sea ice. In this study, passive acoustic data recorded between 2017 and 2022 at six locations around the Svalbard Archipelago, Norway, were analysed for the seasonal and spatial vocal occurrence of this endangered bowhead whale stock, using a combination of Long-Term Spectral Averages and visual/auditory verification. The results were subsequently correlated to seasonal patterns in environmental conditions. Bowhead whale vocalizations were detected at all study sites, but there was significant variation between locations and years in acoustic presence and singing behaviour. Consistent, high detection rates of singing west and east of Svalbard suggest that these sites serve as key areas for overwintering and breeding. The lower and fluctuating detection rates north of Svalbard suggest that this area serves as a movement corridor between regions. Significant positive correlations between bowhead whale acoustic activity and high sea ice concentrations emphasizes their ice-affiliated nature. This study provides novel information on the distribution and habitat use of bowhead whales in the Svalbard area and raises concern for the future of this population, in an Arctic that is experiencing rapid sea ice habitat loss.

How many more #whales need to die before something changes❓

The day before this humpback whale was found dead, our crew arrived at Coronation Island, where eight supertrawlers were already dragging their massive nets through waters full of feeding whales. One of them was the Antarctic Endeavour, which killed this whale the next day.

This isn’t a rare tragedy. It’s the result of letting industrial fishing continue in places that are supposed to be protected.

Help us push CCAMLR to turn this proposed marine protected area into a real one, before more lives are lost. ➡️ Comment, share, and use our krill toolkit via the link in our bio. Let’s #StopThePlunder together!

[Morris et al.] Experimental observation of gray whale skull vibrations amplified in the bony hearing complex nature.com/articles/s41598-025 🐋 #Cetaceans #MarineMammals #MarineLife #MarineBiology #Whales #Science

NatureExperimental observation of gray whale skull vibrations amplified in the bony hearing complex - Scientific ReportsMysticete whales have bilateral bony ear complexes (tympanoperiotic complexes) that amplify low frequency vibrations in proximity to their vocalization ranges. Understanding the functional mechanics would enable precise predictions of mysticete hearing sensitivity, which is currently unknown. We conducted experiments on a juvenile and an adult gray whale skull from deceased animals to measure the vibrational dynamics between the tympanic bullae and the skull. Relative motions between bullae and skull indicate sound transfer to the inner ear. For the juvenile, assessments were performed on (1) a 3D-printed plastic skull-replica, (2) the original skull after much of the soft tissue had been removed by dissection, and (3) the denuded skull after hydrogen peroxide was used to erode the remaining soft tissues. We excited vibrations in the juvenile skull underwater by projecting sound in a test pool, ranging from 170–1000 Hz. Additionally, we measured in-air vibrations of the plastic, denuded, and adult skulls using a mechanical shaker to drive vibrations anteroposteriorly (rostrum-to-tail) from 150–1000 Hz. The results consistently showed amplification of vibrations at the tympanic bullae compared to the base of the skull, demonstrating a mechanism by which low-frequency sound is transferred from the environment, through the skull, to the inner ear.

"This helix of beauty and violence is what makes Long Beach so dynamic, defined by polarities. Like a blade or a cliff, the edge of the sea shows the flimsy line separating life from death. On one side: sandcastles, seashells, long walks. On the other: rip tides, hypothermia, drowning." —Devon Fredericksen for Switchyard
