La marea nera sta distruggendo i coralli giganti nel Golfo del Messico

Era il 20 aprile 2010 quando la piattaforma petrolifera Deepwater Horizon ha cominciato a sversare nelle acque del Golfo del Messico il petrolio dal pozzo Macondo, situato a oltre 1.500 metri di profondità.
La marea nera a distanza di mesi dal disastro, e dopo la chiusura della falla, torna a far parlare di sé. Dopo l’annuncio dei progetti per ristabilire la vita marina nelle acque del Golfo, come il 100-1000 partnership, la BP potrebbe essere responsabile della morìa dei coralli giganti che vivevano vicino al pozzo della piattaforma petrolifera.

Lo ha rilevato la spedizione scientifica a bordo della nave oceanografica Ronald H. Brown che ha analizzato i fondali vicino al pozzo Macondo. Come ha dichiarato Timothy Shank, uno dei ricercatori della Woods Hole Oceanographic Institution

I coralli giganti nelle vicinanze del pozzo sono coperti da una sostanza nera e o sono morti o stanno morendo. In qualche caso sono rimasti soltanto scheletri.

La fauna marina è stata quella più danneggiata dal disastro ambientale del Golfo del Messico, ricordiamo l’allarme per il cavalluccio marino nano, già specie a rischio estinzione, ma ora anche i coralli giganti sono seriamente minacciati. La spedizione scientifica ha rilevato che il 90% di 40 gruppi di coralli, compresi in un raggio di circa 400 metri attorno al pozzo, sono stati danneggiati o stanno morendo. Le cause? l’esposizione al petrolio, l’impiego di disperdenti chimici e la mancanza di ossigeno. Come ha spiegato lo studioso

La vicinanza al sito del disastro e la profondità sono più che una pistola fumante, sono un cannone fumante. Quello che abbiamo trovato è il frutto dell’esposizione al petrolio, ai disperdenti chimici e all’acqua deprivata di ossigeno.

I coralli più distanti dall’area del pozzo non sembrano aver subito danni, eppure gli esperti temono di aver scoperto solo la “punta di un iceberg” di quello che può essere accaduto nei fondali marini e nell’intero ecosistema del Golfo del Messico dopo il disastro.

  7. First off I would like to say fantastic blog! I had a quick question that I’d like to ask if you don’t mind. I was interested to know how you center yourself and clear your head prior to writing. I have had difficulty clearing my thoughts in getting my thoughts out. I do enjoy writing however it just seems like the first 10 to 15 minutes tend to be wasted just trying to figure out how to begin. Any suggestions or hints? Kudos!

  10. The Zune concentrates on being a Portable Media Player. Not a web browser. Not a game machine. Maybe in the future it’ll do even better in those areas, but for now it’s a fantastic way to organize and listen to your music and videos, and is without peer in that regard. The iPod’s strengths are its web browsing and apps. If those sound more compelling, perhaps it is your best choice.

  18. I want to show my thanks to the writer for rescuing me from such a trouble. As a result of looking out through the world wide web and meeting solutions which were not powerful, I was thinking my life was over. Living without the strategies to the issues you have sorted out by means of your website is a serious case, and ones that would have in a wrong way affected my career if I hadn’t come across your blog post. The understanding and kindness in playing with all things was valuable. I am not sure what I would’ve done if I hadn’t come upon such a subject like this. I can at this moment look forward to my future. Thank you very much for this impressive and result oriented help. I won’t be reluctant to propose your site to anyone who desires care on this topic.
