Tohorā foraging further for food w/ Emma Carroll: March 1, 2023

Tohorā (southern right whales) are travelling further north and south to forage for food across the Southern Ocean. Researchers say these changes have been occurring over the past 30 years, following a lengthy period of "remarkable consistency" in whale feeding ranges dating back to the 1700s. 

Joe speaks to Emma Carroll from the University of Auckland on this matter.
