ZARONILI SU U DŽINOVSKU RUPU U OKEANU: Otkrili su nešto od čega vam neće biti DOBRO!

Ukoliko temperatura mora na vreme opadne, korali mogu da prežive...

Grupa ronilaca nedavno je istražila Plavu rupu (Blue Hole) u Velikom koralnom grebenu kod Australije. Duboka rupa u morskom dnu nalazi se 200 kilometara severoistočno od ostrva Dejfrim, a u njoj se krije pravi mali čarobni svet korala.

We call it 'The Crack'.... Up there with the most ultimate snorkels I've ever done... After diving the Blue Hole over the weekend, we decided to move sites and check out what looked like a huge crack in the reef spotted on google maps. Open to the ocean at one end, and closed in by Reef at the other. The total length was over a 1Km long, about 50m wide and the depth is still unknown. The strong current along the walls meant we had to drift the whole way. This video doesn't do the site justice as most of the bigger inhabitants were not keen to come close. Only filmed fish and corals at the top on the edges. Freediving into the depths we saw Grey Reef Sharks, Whitetip Reef sharks, Maori Wrasse, a Tawny Nurse and a 3m Lemon shark. Seeing a huge school of Humpnose Unicornfish was definitely my highlight. Counted over 100 in one photo. It's a long way offshore this spot, but hopefully we'll get back there one day. The Crack...

Reč je o velikoj šupljini u morskom dnu, otvorenoj prema površini, okruženoj ostrvcima sačinjenim od krečnjaka ili od koralnog materijala. Nastala je tokom poslednjeg ledenog doba kada je nivo mora bio osetno niži nego što je danas.

Yesterday's Blue Hole mission in the Great Barrier Reef. This Blue Hole has previously been explored and documented by geologists who suggested it could be even older than the famous Great Blue Hole, in Belize. It's location is in one of the least explored parts Great Barrier Reef, over 200km from our home @daydreamislandresort . To get there we had to travel overnight for 10 hours and time the tides perfectly... Navigated the shallows with google maps until the blue dot was over the hole. Was well worth it! Inside the walls was similar to the site we explored a few weeks back, but this hole was deeper and almost perfectly circular. We dived down to just over 20m yesterday, before hitting bare sediment, that slowly sloped towards the centre. Again it was great to see big healthy coral colonies. Stay tuned for video footage of the coral within...

Tokom vremena, dok je to područje bilo kopno, kiše i hemijski nagrizajuće materije rastopile su krečnjaččko tlo i stvorile su velike špilje. Nakon nekog vremena svod tih špilja je popustio, pri čemu su nastale ovakve podmorske provalije. A s postepenim otopljavanjem nakon završetka ledenog doba, ove šupljine su se ispunile vodom jer je nivo mora počeo nezaustavljivo da raste.

Independent navodi da je Džoni Gaskel, morski biolog iz Australije, podelio na Instagramu fotografiju uz koju je dopisao:

– Plavu rupu su geolozi ranije opisivali navodeći da je možda starija čak i od čuvene Velike plave rupe u Belizeu. Ovo mesto je jedno od najslabije istraženih delova Velikog koralnog grebena. Kako bismo stigli do ovog mesta morali smo da putujemo 10 sati tokom noći da bi nas dočekalo savršeno vreme i savršena plima. I vredilo je.

Today's mission to Fairy Reef. This was the first time we've explored this part of the Great Barrier Reef, located directly north of the Whitsundays. Was a bit of a mission to get there but well worth it. Awesome swim throughs and a lot of vivid coloured stony corals... unfortunately the reef is not all like this, Corals that are just holding on, any warmer and even these could be gone.

On je napisao i to da su zidovi ove rupe pod morem vrlo nalik lokaciji koju su istraživali nekoliko nedelja ranije, samo što je ova rupa dublja i skoro savršeno okrugla.

– Juče smo ronili nešto dublje od 20 metara, pre nego što smo naišli na sedimente koji su nas polako usmeravali prema središtu. Bilo je divno videti zdrave koralne kolonije – rekao je Gaskel.

Yesterday in the Great Barrier Reef!!! After spotting this deep blue hole on google maps we decided to head far offshore, out further than our normal Reef trips to see what dwelled within. What we found inside was hard to believe considering 5 months ago a Cat 4 cyclone went straight over the top of it. At around 15m - 20m deep there was huge Birdsnest Corals (Seriatopora) and super elongated Staghorn Corals (Acropora) both of which were among the biggest and most delicate colonies I've ever seen. Totally unaffected by the cyclone. The position of this deep hole within the lagoon walls has obviously protected these corals for decades. We may very well be some of the first to dive this deep hole as it was hidden within one of the Great Barrier Reef's biggest lagoons...

Tako dolazi do bleđenja koralja. Ukoliko temperatura mora na vreme opadne, korali mogu da prežive.

No, za one korale kod kojih je proces uzeo previše maha, više nema spasa.

“Plava rupa” u Belizeu široka je 300 metara i 125 metara duboka. Smatra se najvećom takvom u svetu, dok je najdublja na svetu podmorska rupa u Južnokineskom moru, duboka 301 metar.
