Geomagnetic Storms Probably Don’t Cause Mass Cetacean Strandings

by Morgan Rehnberg 28 October 20207 March 2023

Solar-induced geomagnetic activity and mass strandings of whales and dolphins on shorelines both show seasonal patterns, but the beachings likely result from multiple environmental factors.

Seasonal and Annual Changes in Pitch in Blue Whale Calls

by Terri Cook 7 June 201929 November 2022

Six years of acoustic recordings detect seasonal shifts in blue whale vocalizations that correlate with the presence of icebergs, a primary source of ambient ocean noise in the southern Indian Ocean.
