Current satellite information shows that Lea and Roberto are deep within Bahia San Blas, while Yaana is a bit more towards the entrance channel of the bay. Click on the map above for a larger image.

March 30, 2007 - Killer Whales?

As we start to post these location maps, everyone is asking "how long will the satellite tags last?" The answer is...well, we do not know. We were receiving signals months beyond the expected life cycle of last year's tags---and we would love to see the same thing this year. But in reality, this year's tagging site is quite different from last year, even though both are on the coast of Argentina. The salinity and water conditions are different. And there's the killer whales (that's one on the left, near our tracking site)... So the real answer is that we should consider each day of transmission to be valuable, as they can stop any day. Keep checking for my postings to and we will see how long the tags last together.
