New material on Cruising for Naturalists

I have added new material about Cruising around Australia: and more specifically: “do you really want to be a cruise lecturer?” Also, one can see the 11 talks I gave during the cruise here. Keep in mind that these talks will appear disorganized without my oral explanations that accompanied them. This despite my trying to explain each slide with text. But they should give the viewer a flavor for the content of the material I was trying to present.
