Oceans are vast bodies of saltwater that cover over 70% of Earth's surface. They play a crucial role in regulating the planet's climate, providing a habitat for a wide variety of marine life, and supporting various industries such as fishing, shipping, and tourism. Research on oceans encompasses a wide range of disciplines, including marine biology, oceanography, and climate science. Scientists study ocean currents, marine biodiversity, ocean acidification, and the impact of human activities on marine ecosystems. Understanding the oceans is essential for addressing issues such as climate change, overfishing, and pollution, as well as for conserving marine biodiversity and ensuring the sustainable use of marine resources.
