jibraaltar jalasandhi poorv mein bhoomadhya saagar ko pashchim mein atalaantik mahaasaagar se jodti hai. iske uttar mein Europe ke Spain aur jibraaltar kshetr hain jabki dakshin mein uttari afreeka ke marokko aur seuta kshetr hain. apne sabse kreebi bindu par Europe aur afreeka ke mahaadveepon mein keval 14.3 kimi ki hi doori hai. kyonki yeh bhoomadhya saagar aur atalaantik mahaasaagar ke beech mein yaataayaat ka ek sikuda hua bindu hai isaliye is jalasandhi par kbja karna aitihaasik roop se mahatvapoorn raha hai. madhyakaal ke aarambh mein uttar afreeka se aae arabon ne is jalasandhi ko laanghakar Spain par kbja kiya tha aur speniyon ne kai sau varsh baad unhein jalasandhi ke paar khadedkar apna saamraajya fir sthaapit kiya tha.

bhaugolik itihaas va bhavishya

aaj se 59 lakh varsh poorv jibraaltar jalasandhi dheere-dheere band ho gayi aur bhoomadhya saagar aur atalaantik ka sampark toot gaya. samay ke saath bhoomadhya saagar sookhata gaya aur iske paani mein namak ka sankeindran (konsantreshan) badhta gaya. anumaan lagaaya jaata hai ki yadi aaj jibraaltar jalasandhi band ho jaae to 1000 varshon mein bhoomadhya saagar ka adhiktar paani sookh jaaega aur yeh ek faili hui namak se bhari droni ban jaaegi. aaj se lagbhag 53.3 lakh saalon pehle jalasandhi khulne lagi. yeh pehle to ruk-ruk ke hua lekin fir jalasandhi poori tarah khul gayi. is se atalaantik mahaasaagar ka paani bhayankar bahaav se bhoomadhya saagar mein girne laga. anumaan lagaaya jaata hai ki bhoomadhya saagar ko poori tarah bharne mein kuchh maheeno se lekar 2 varshon tak ka samay laga.[1][2] bhoomadhya saagar ka frsh atalaantik se lagbhag 1 kimi neeche hai aur is pravaah mein aadhunik amejn nadi se 1000 guna adhik pratisaikind ki jalamaatra dahaadti hui bhoomadhya saagar mein giri hogi.[1]

bhavishya mein afreeka aur Europe ki lagaataar kam hoti doori se aaj se laakhon varsh baad yeh jalasandhi fir se band ho jaaegi aur bhoomadhya saagar mein shushkikran fir hone lagega.
