Like anyone who dove Friedman's Sink (Chiefland, FL) this summer, I was plagued by ticks. I'm no fan of the little arachnids, but my conscience was bothered by the fact that those unfortunate ones who'd attached to me prior to the dive were unable do survive it. Since members of the order Ixodidae can easily tolerate immersion to depths in excess of 30 meters for periods of several hours, they did not die from drowning; rather, they did not survive the decompression.
As a Stage 4 Vegan™, I do not allow myself to intentionally harm animal life, of any kind or for any reason. As a cave diver, I feel a responsibility to anyone (thing?) that goes diving with me, whether I invited them along or not. So my question for the community is: are there any appropriate modifications to tables/algorithms/gradient factors I could make to accommodate decompression for the little hitchhikers? In my attempts so far, a Bülhmann ZHL-16C with GF ranging from 30/75 to 15/55 do not do the trick. Perhaps I should try some recreation trimix, like 21/55?
