On July 2010 expedition to hunt Tacos ("Octopus") in Kaneohe Bay, I was struck by the amount of Coral Bleaching. There appear to many potential causes of the coral bleaching including "Invasive Specie" and "Rising Mean Temperature". There are numerous studies on subject, google "Kaneohe Bay Coral Bleaching" to find various article. Aloha, UC

  • 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

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

  • @dstick1 ROFLMAO......

  • 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 .

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

see all

  • 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.

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

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