Weekly Summary

Information updated to: July 4, 2022

We have been tracking the activities of Amalthea, a mother with calf, for 281 days. This female is the only whale tagged in 2021 whose transmitter remains active. She has thus far traveled 17,520 kilometers (10,886 miles) over the 256 days since she left Golfo Nuevo in Peninsula Valdes.

For several weeks now Amalthea has been feeding in the Scotia Sea, west of the arc of the Islas Sandwich del Sur (South Sandwich Islands).

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.
