GOLFO NUEVO

GOLFO SAN MATÍAS

Update January 23, 2023

GOLFO NUEVO:
One week before the end of January 2023 we continue tracking 7 whales with active transmitters. During this past week the greatest changes in location were made by Malaquita and Turmalina, two mothers with calves, and by Zircon, a solitary adult. Malaquita continued traveling northwards over the continental shelf, passing Granate and arriving at latitude 43.9°, almost the latitude of Peninsula Valdés. Turmalina, the only tracked whale in the deep ocean basin, traveled 300 kilometers (186 miles) north, describing some circles along her route, possibly indicating that she was feeding. Today she and Malaquita are at almost the same latitude. Zircon, on the other hand, traversed the 800 kilometers (497 miles) of the Malvinas (Falklands) plateau from north to south, entering the Scotia Sea on January 22. Zircon is this season’s southernmost whale, having reached 55.43°S today.
The other tracked whales remain near their previous locations. Andesina, a mother with calf, stayed over the continental slope, at the latitude of Mar del Plata, while Amazonita, a solitary individual, has remained west of the continental slope off the mouth of the Rio de la Plata, since the middle of December. Farther south, over the continental shelf, Granate, a solitary individual, is slightly north of Cabo Dos Bahías, and Agata, a mother with calf, is off the northern coast of Santa Cruz province.

GOLFO SAN MATÍAS:
No whales with active transmitters remain in this group.

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.
