I trust members in this group took advantage of the free postings of the live presentations from WBAC 2020 from Mexico over the last few days. There have been some real gems. I think some of the talks will go up on WBAC s youtube channel shortly. In the mean time following is the talk I recorded for WBAC just before I am about to join the Humpback whale migration up the East coast of Australia in my marine conservation yacht Migaloo 2. I have been feeling the call to dive in deep with the whales so Im sailing off tomorrow for a few months. Following are some notes I prepared for the WBAC talk or alternatively you can listen to the talk I recorded below.
