Dan Costa, at King George Island, near Antarctica -- This is the first in a series of short dispatches from an expedition to do a fur seal survey, starting around Livingston

We deployed the last tag on Sunday in the Cape fur seal rookery at Kleinzee, on the shores of a DeBeers strip-mining diamond mine.

One of the things that TOPP does is develop biologging techniques and technology -- putting satellite tags on animals who roam the ocean and send back data.

Greetings from South Africa!!

We're on the northwest coast of South Africa in the middle of a diamond mine.
