Gemela’s 22 day tracking route (1,316 km)

White circle indicates last position received.

September 27 – October 14, 2019

Gemela briefly explored the coasts of Golfo Nuevo, then left the gulf to remain in nearby waters. We do not know the sex of this young whale. To learn if it is a female or a male it will be necessary to wait until we have the results of the DNA analysis, because it is not possible to differentiate between the sexes from above the surface of the water, unless it is possible to view the abdomen. Gemela’s transmitter stopped transmitting on October 14, when Gemela was 100 kilometers to the east of Rawson.

The color of the dots follow a time sequence where the green dots represent the first locations in this period and the red dots the most recent locations, progressing through yellow and orange. The last position, indicated by a red dot with a white border, shows the geographic coordinates and time of reception of the transmission.
