We are definitely aware of the humpbacks in Johnstone Strait at the moment. At 8:06pm there was one short call and since then some blows were picked up on the Critical Point hydropphone. Helena & Kirsty 21 Sep 2013 20:58:01 PDT Distant calls audible. More than half an hour ago we heard the last Humpback vocals on Local Left before it got quiet. Now we can hear some Humpback calls again but very distant and still very few calls. It's probably the same Humpback as we heard before but we don't know its location, yet.
