The pod of Orcas that has been around for a while are still making appearances once or twice a day, to the frustration of the dive team. They can't dive if there are Orcas or Leopard Seals around, though they did get a very good view a couple of days ago when the whales turned up just after they set off for a dive. Another pod that was around earlier are now off the Falklands (one of them was satellite tagged). I sat up by the memorials on Sunday morning, watching them come in from the south before they headed reasonably close past the wharf. Since then I have set up in the Bonner lab and can see them approaching the wharf from the office window, giving enough time to grab the camera and run out to get photos. The brown wash to their colouring is algae (diatoms) which often stain whales in the Southern Ocean and around Antarctica.
