– [Narrator] However in October 2019, tragedy strikes the area.
The crown takes a direct hit.
– [Speaker] It was fully bleached, like all of it.
It was simply all white.
– We noticed an enormous bleaching occasion.
I imply, the corals that we got here to know and love blanketed with snow, it appeared like.
– [Narrator] Then 4 months later, the staff notices one thing extraordinary.
– [Speaker] After we return in January, the corals get higher.
February they get even higher.
Might, the corals are trying high quality.
They’re trying lovely.
– [Speaker] We’ve got this lovely Cayman crown reef that it has recovered.
The corals on this area are resilient.
– [Narrator] The information reaches coral knowledgeable Myles Phillips.
He joins the staff to examine the crown’s.
Will Haman shares his principle.
– [Will] Let me offer you the geographic context.
So that is this Gulf of Honduras.
– [Myles] Yeah.
– [Will] And this channel, that is your Cayman Crown.
What you gotta keep in mind is that that is the Cayman Trench.
Right here, it is already 1000, 1500 meters after which drops, drops, drops, drops, drops 7,600 meters, deepest level.
– At its deepest, the ditch is over 4 miles down.
A 15 pound bowling ball dropped in would take over an hour and a half to hit backside.
Chilly currents rising from these depths sweep vitamins as much as the crown.
– [Will] This water comes slamming up onto this vertical shelf.
So the place we had been, these jewel reefs- – [Myles] Proper on the prime of it.
– [Will] Okay.
– That is the supply of your upwelling.
– [Will] Precisely.
– [Narrator] The upwelling flows alongside folds of rock and coral that act like pipes and channels in a cooling system, easing temperatures and offering vitamins.
– [Will] The opposite issue that we have not talked about we get 4 meters, like 12 ft of rain that falls all within- – [Myles] All on this area.
– By agricultural lands.
– Into this one bay via this identical little channel.
– [Will] Precisely.
– So that is forming like a roof, like a shade.
– That is it. – Over this coral reef.
– That is it.
– [Narrator] Simply as the Caribbean water temperature peaks, muddy water washes over the reef.
Rising analysis suggests that this runoff might protect corals from damaging daylight.
– They’re getting shade, they’re getting fed they usually’re getting cooled.
So the place all the remaining of the Caribbean took that bleaching and wrestled coming again, this space is resilient due to these components.
