#TrackingWhales

The #trackingwhales Research Project began in 2014 with the objective of learning the migratory routes and feeding areas of the Southern Right Whales which reproduce in the northern Patagonian gulfs. In September 2019, 23 whales were equipped with satellite transmitters in Golfo Nuevo, Chubut Province. Their real time transmissions will let us monitor in detail their travels in the Southwest Atlantic Ocean.

Click on each individual to see its travels in detail.

Note: The transmitters do not affect the behavior of the whales.
Transmission stops when the transmitter falls off, which can occur weeks or months after its placement, or when the batteries lose power,
usually after several months.
The average transmitter’s transmission life is 100 days, with the maximum recorded duration being 240 days.

Updated information as of April 27: The map shows no more blinking lights. The last functioning tag has stopped indicating the positions of whales swimming in the Southwest Atlantic. Three days ago we lost contact with Tigresa, who carried the last active transmitter and traveled farthest south among all tracked mother-calf pairs. We hope that the 23 individuals we have been tracking during the past eight months will return to the calm waters of the Peninsula Valdés in the coming weeks.

Although this report concludes our weekly tracking updates for whales tagged in 2019, we will remain busy processing the information collected and preparing for the 2020 season of #trackingwhales.
