Weekly Summary

Information updated to: July 25, 2022

We have now been tracking Amalthea, a mother with calf, for 300 days. Their migration started on October 20, 2021, when they left Peninsula Valdes. During this past week Amalthea continued traveling northwards through the Mar de Scotia (Scotia Sea), passing on the east the Islas Georgias del Sur (South Georgia). Amalthea has covered 1,100 kilometers (684 miles) in two weeks’ travel.

Important information about satellite tracking

Animal welfare: New generation satellite tags used by the project may have minimal and short-term effects on the behavior and health of the animals. This research strives to use the safest technology to track whales.
Positions recorded: Positions have a margin of error of 200 to 2000 meters (which is the reason some tracks that are close to shore seem to be on dry land).
Duration: The devices stop sending data when they become detached, which can occur weeks or months after their deployment, or when their batteries run out, depending on various factors, but mainly on the type of tag used. In 2021, we deployed 12 short-term and 6 long-term devices.
