I agree the photos don't look good, but they are two snapshots. In particular, the tender shouldn't have had their hand on the coral. How do you know the sampling was destructive, however? Perhaps the coral head remained perfectly intact after the core was taken. It looks like the person doing the drilling is standing behind the coral head, not on it, which would potentially be way more destructive than touching it with a hand.
In general scientists are usually held to much higher standards than the general public. For example, I study frogs. In most of the U.S., you can legally go out, catch a treefrog, and skewer it on a fish hook with no permit or license required for the frog. In my scientific work for these same frogs, I have get a permit from the State, and a separate, very extensive IACUC permit from my University. And this is to conduct non-lethal behavioral experiments, where the frogs are released back into the wild.
That's not to say that there are not scientists who do destructive things. In my 25 years of experience as a field biologist, however, virtually every scientist I've interacted with are careful not generate lasting negative impacts.
Upfront: I think we, as in you and I, are generally on the same page here.
And I do not know that the coral head was actually sustaining damage beyond the core taken itself. I do know that I and many others were informed that it is a bad and coral stressing thing to to touch coral in any way, bare handed, gloves or with find or booties both the kind on your feed and the kind between thighs and rump...
Anyway I assume (may have read something indicating so) that sort of advise would be rooted in some sort of scientific finding and backed up by observation & research (as some of the damage is notable not necessarily immediately but only longer term I thought / heard). I may be wrong on assuming so.
Am I?
In the end one could always argue that e.g. a fallen giant tree in the forest (not taken for the timber industry, just fallen by man or by nature) is not detroying anything as it makes room for more saplings and as ot decays over centuries hosts an unbelievable amount of animals and organisms. And therefore one could argue by extension that there is no point in taken offense to tourists or scientists climbing over corals. I am not suggesting you are making that argument here. Neither am I.
Nor would you necessarily fell a forest giant to get to a tree frog. You might climb the tree. The tree might suffer some rope anbrasions, maybe a few puncture wounds if you used screws or climbing irons of some sort. But generally it is thought to withstand that thing just fine.
Maybe that thought would change if the tree would be visited in that way by hordes of tourists. And so, even if a scientific visit to that tree does no harm in the big picture, many more people doing the same might. And so it mighg be considered bad to promote that behavior or invite emulation, even so the originsl behavior was not really wrong.
I have no good understanding why corsal is thought to be a whole lot more sensitive to touch then say trees. I thought that was some sort of truism found out and perpetuated by scientists. I may be quite wrong.
Am I?
If I am wrong, I concede.
If I am not wrong, then, frankly, I fail to see what the point is to ask if I know if that particular coral actually sustained damage due to the treatnent it received or will develop damage in time due to it.
Isn't this (link below) essentially what scientists tell the general public in terms of how to behave around coral? And would those sampling taking pictures then not truly indicate that those scientists most certainly do not hold themselves to a higher standard? And doesn't then a lot of what
