Katharine and friends are on the move in 2015 presumably following seasonal migrations.
The three orange dots in the Gulf represent pings on there separate sharks. They there are the two off Georgia and Katharine off NE Florida again. There is one individual way out in the Atlantic to the east.
Katharine is presumably heading south again. She came in close to shore as well last year. Wonder if she'll head into the Gulf again this year?
Katharine's pings during surfacing intervals over the last year.
