लवणता (Salinity) क्या है | What is Salinity| Lecture-9 |By- Prof. SS Ojha Sir | Geography GK

पृथ्वी के लगभग 71% भाग पर महासागर फैले है | महासागरों की कई गतिया है, जैसे- लहर , धारा, ज्वार तथा सुनामी इत्यादि | यह ऊर्जा प्रदान करते है, जैसे - लहर ऊर्जा , ज्वारीय ऊर्जा ओटेक ऊर्जा, ओस-प्रे ऊर्जा इत्यादि |
महासागरों में सम्पन्न नितल / निक्षेप संसाधन मिलते है,- जैसे एल्युमीनियम, कोबाल्ट, निकेल, मग्निशियम, लोहा इत्यादि | महासागर जैविक संसाधनों मेंभी संपन्न होते है, जैसे - मछली , प्रवाल तथा औषधि मूल्य की शैवाल | महासागर हमें नमक तथा नौकायन सुविधाए प्रदान करते है |
पार्थिव उष्मन तथा बर्फ पिघलने के कारण समुद्र तल उठ रहा है | इस प्रकार महासागर तटीय भू-भाग तथा द्वीपों को ढक ले रहे हैं | दो देशों के बीच समुद्री संसाधनों पर विवाद हो रहा है | इसलिए अन्तराष्ट्रीय समुद्र नितल प्राधिकरण तथा अन्तराष्ट्रीय महासागर कानून बबये गए है |
इस प्रकार आज का वर्तमान तकनीकी मानव विश्व महासागरों के विभिन्न पहलुओं की तरफ देख रहा है, और उनका अध्ययन कर रहा है |
Oceans cover about 71% area of the earth. Oceans have several motions like Wave, Current, Tide, Tsunamis etc. These provide energy like Wave Energy, Tidal Energy, Otec Energy, Osprey Energy.
Oceans have rich Bottom Deposits/ Resources like Aluminium, Cobalt, Nickel, Magnesium, Iron etc. Oceans are rich in biotic resources such as fish, Corals and algae of medicinal value. Oceans provide us salt and navigation facilities.
Due to global warming and ice- melting sea level is rising. Thus oceans are occupying coastal land and island.
Disputes arise on the marine resources between two countries hence International seabed authority and International ocean laws have been formulated.
Thus today present technological man is looking at and studying different aspects of world oceans.
