Observations of "Coral Bleaching" in Kaneohe Bay (Duran Duran "Come Undone")

[cpj1379]

The only documented Bay-wide bleaching event occurred in 1996, when most of the corals in the inner bay bleached substantially. Bleaching leaves all or most of the entire coral white (or very light). The cause of mass bleaching events (e.g., throughout the main Hawaiian Islands, along the Southern GBR, etc.) is elevated temperature associated with climate change. Coastal pollution can and does cause serious problems (K-Bay is a good example), but not mass bleaching. Climate change is the cause.

@cpj1379 thanks, appreciate the education

[cpj1379]

The good news is that none of the corals in the video (that I could see at least) were bleached. The 'bleached tips' you show are all on the coral Montipora capitata. Corals spatially segregate zones of rapid calcification and photosynthesis. The branching form or this species grows mostly at the branch tips, where the density of zoox. is very low, giving the white appearance. In fact, most branching species have lighter or white tips. This is the normal, healthy state for this species.

Clearly the problem has been brought about by the increase in hairdressers diving on thier days off!

@dstick1 ROFLMAO......

@808surfmongul after a hiteus of effectively 18 years (except one other time 2 years ago) went surf today at Publics (in between Doc Appointments) Caught one wave apparently cut-off a hot-young wahine, although I think she unfairly snuck inside me got up earlier, then cried foul …she gave me “hola-hola” holler…. And I was like “scuse me while kiss the sky…..thank you, JESUS .....and I’m outta here”.... great time (no takos on the dive)... see at North Beach soon!

[jfooj]

Did you get some tako?

[UnderseaCaveman]

@jfooj nah, didn't find, we were probably in the wrong area (not close enough to Chinaman's Hat)

[777Marlene]

@jfooj is that all guys think about is gettin' some taco?

[jfooj]

@777Marlene Over here we call it "poke squid".

[777Marlene]

@777Marlene but i hope you find some er...er..."poke squid"...ughmm....soon((huggs)­)

[medini2]

interesting video. 15 years ago i got to hear part of a lecture on the subject of the demise of coral throughout the world & was told textile industry runoff was largely responsible for most of it....from chlorine bleach used to remove all color from fabric before it is dyed .

[UnderseaCaveman]

@medini2 yeah, could be chemical (run-off), biological (invasive specie) or physical (thermal, temp).... scientists don't sound certain yet.

[dangermous1968]

wow, that is disturbing, what could be the cause, has this heatwave had a big effect on the ocean water temperatures? thanx for the vid Undersea Caveman..

[UnderseaCaveman]

@dangermous1968 The scientists don't sound certain of what exactly is the cause....could be elavated temps or invasive specie ..

[anyusmoon1]

Was dat a honu at 1:18?

[UnderseaCaveman]

@anyusmoon1 Yes.....good spot (da honu)....yeah, it's bleached coral, and pervasive.

[777Marlene]

aww U.C. i hope there is someway for the biologist's to come up with a plan to stop the spread of this, you would think the oceans being so vibrant at one time ,and more inaccessible ,would be more immune to this fate, but if the oceans can be hurt this easily, makes one wonder what the fate of the land would be.....keep on rockin'....(huggs)

[UnderseaCaveman]

@777Marlene Mahalo....yeah, I hope the biologists figure out cause, and then the community pays attention and heed.... we'll see!!!

[anyusmoon1]

Is the bleached coral dead, hardened or?
