For each person on the planet there are approximately 60 billion gallons of ocean water and water is 60& of the Earth so obviously Oceans are a big part of that. There are four main oceans, those are the Pacific Ocean, Atlantic Ocean, Arctic Ocean, and Indian Ocean.
The Pacific ocean borders China, Japan, and Russia to the west and the United States and Brazil to the east. Those five countries make up one third of the world population. And the United Nations human developmental index (a measure of statistics that takes into account a populations schooling, income, literacy, and life expectancy) most of the countries bordering the pacific ocean are highly developed population-wise. Some of the exceptions are Guatemala, Vietnam, Cambodia, and Papua New Guinea, which are not highly developed. Fisheries in the southern, northern, and eastern regions of the pacific ocean are most productive. Most of the pacific oceans catch is herring-like fish like Japanese sardine, south american sardine and the peruvian anchovy. These fish are often processed into fish oil or fish meal which among other things, serve as a food source in fish farming.
Area of Pacific Ocean - 64 million square miles.
Mean depth of Pacific Ocean - 13,741 feet.
Maximum depth of the Pacific Ocean - 36,161 feet, the marina trench.
Volume of water - 167 million cubic miles.
The Atlantic Ocean borders Africa, the countries on the west coast of Africa are mainly poorly developed but the two developing hot spots are Ghana and Nigeria. But also three of the worlds largest cities border the south atlantic. Those cities are Buenos Aires, Rio de Janero and Sao Paulo are all located along the east coast and border the south atlantic. More than 26% of the worlds fish catch comes from the atlantic ocean and 2/3 of that catch from the northeast and east area of the atlantic. The north atlantic is the most heavily fished area. Sardine, anchovy and herring for the most part. Bordering the atlantic ocean are many of the worlds most economically developed regions. particularly ones in north america and northwest europe regions. Many countries have a lot of fishing and pollution pressure from the north atlantic.
Area of Atlantic Ocean - 32 million square miles.
Mean depth of Atlantic Ocean - 12,612 feet.
Maximum depth of the Atlantic - 30,248 feet.
Volume of water - 72 million cubic miles.
The Indian Ocean borders pakistan, india, and bangladesh on the north coast and these countries are among the ones with the highest population densities and are the poorest. The Indian ocean is also home to many coral and mangrove swamps which house many special creatures and precious ecosystems.
Area of Indian Ocean - 28 million square miles.
Mean depth of Indian Ocean - 12,704 feet.
Maximum depth of the Indian Ocean - 23,812 feet. Java Trench.
Volume of water - 68 million cubic miles.
The Arctic ocean is the smallest ocean and it does not have a lot of fisheries due to it’s location and size. It borders Russia, Canada and Greenland and it is very very cold.
Area of Indian Ocean - 4.7 million square miles.
Mean depth of Indian Ocean - 3,665 feet.
Maximum depth of the Indian Ocean - 17,878 feet. Eurasian Basin.
Volume of water - 3.3 million cubic miles.
