Popular Science of Navigation —— Talking about the Pacific Ocean

The Pacific Ocean is the largest ocean on the earth, accounting for about 46% of the earth's water surface and 32.5% of its total area. The Pacific Ocean spans the coast of Antarctic continent, reaching the Bering Strait in the north, Asia in the west, Oceania and Antarctic continent in the south and America in the east.

China's main export route to the United States and western countries is the American-Western route. The more active maritime trade between China and ports in the western United States is through Vancouver, Canada, and the juande Strait in Fuka, which is owned by the United States and Canada. Seattle, USA.

The fog in the Juan de Fuka Strait is enchanting in the middle of the mountains on both sides of the strait. The United States is on the south bank of the Strait and Canada is on the north bank, but the scenery on both sides is quite different.

In winter, the white clouds implicitly keep her beauty, hovering over the mountains where there are many pines and cypresses. However, under the heavy pressure of the bitter northeast cold wind from Siberia and across the ocean, Baiyun broke into pieces of cotton balls, stretched for miles on the mountainside intermittently, panting, fled everywhere, and suddenly fell into the valley and threw them into the sky.

What's more, the indomitable spirit of the pines also struggled to sway in Li Feng, scarred by the wind, and Lin Tao gave a surging roar. The white top of the mountain is more reminiscent of the flying goose feather snow, which destroys the green jungle like a fox, but it also evokes people's thinking about the turmoil and trauma of the modern world.

In summer, the forest is lush. The whole strait is dressed like a fairyland, the Moon Palace Chang 'e and the Milky Way in the sky. Negative oxygen ions in the air soar in the straits, float in the mountains, and breathe the fresh forest breath, which can probably prolong the life of one hour. The Fuka Strait in Juande is definitely a paradise. As an ocean captain, boating in such scenery is a gift from nature.

North of the Fuka Strait in Juande is the port of Alaska, USA; South to San Francisco, Los Angeles, Long Beach and other ports. Further south is the gulf formed by the California Peninsula, where there are Mexican ports. Further south, there are many countries in the isthmus of Panama on the Pacific side of Central America. A pearl island chain in the Aleutian Islands connects Asia, Russia, Sakhalin and Chiba Islands in northern Japan with North America, and separates the Bering Sea from the Pacific Ocean.

Throughout the year, the Aleutian Islands either spend their winter in white and storms or are shrouded in fog in summer. There are countless ships along the Aleutian Islands, which is the only Pacific Great Circle route in the world. Large container merchant ships from the Far East choose the shortest great circle route from Asia to North America. The northern Pacific Ocean is bounded by the Bering Strait, with a width of only 102 km. Japan faces the North Pacific Ocean and enters the Sea of Japan around the Tsutsugaru Strait. Note that we must be cautious and psychologically prepared to take this big circle route in winter, because winter is basically stormy weather. Captain Yiyang is on the American-Spanish route, and ships often encounter wind and waves.

China's territory is located in the marginal sea on the west side of the Pacific Ocean, namely the Yellow Sea, the East China Sea, the southeast coast and the South China Sea. The eastern part of Taiwan Province Province, the treasure island of the motherland, directly faces the Pacific Ocean, which is the most important Pacific export facing China and the development area of Asia-Pacific Economic Cooperation.

The Pacific Ocean is about 15900 km long from north to south and about 19900 km wide from east to west. In the middle of the Pacific Ocean, it extends to the northwest at about 20 north latitude, including the island chain of Hawaii and midway, and the world-famous international international date line, which artificially divides the earth into the eastern hemisphere and the western hemisphere, forming the geographical concepts of the eastern hemisphere and the western hemisphere.

The Pacific Ocean extends further south to South American countries, and the coastline is occupied by Colombia, Ecuador, Peru and Chile. Chile's Pacific coastline extends all the way to Cape Horn strait of magellan, the southernmost tip of South America! The narrow territory of Chile suddenly blocked a land dam in western Bolivia and Argentina, separating the Pacific Ocean. The southeast is connected with the Atlantic Ocean through the Drake Strait between Tierra del Fuego in South America and Graham Land in Antarctica. The southern part of Cape Horn is a westerly belt roaring in the southern hemisphere. The China scientific research ship "Snow Dragon" should have a deep understanding. When Captain Yiyang arrived in Singapore after loading in Argentina in South America, he chose to go to strait of magellan to avoid the roaring westerlies outside Cape Horn.

In the southern hemisphere, from the Colombian coast in South America to Asia in the northern hemisphere, a string of Pacific island countries are embedded in the Pacific Ocean like pearls, extending to the Malay Peninsula, with the longest east-west length of 2 1300 km. Including the sea, the volume is 7 144 10000 cubic kilometers, but excluding the sea, the volume is 696 189000 cubic kilometers. The average depth with sea is 3939.5 meters, and the average depth without sea is 4 187.8 meters. Mariana Trench is near Guam, with the known maximum depth of11033m.

The dividing line between the southwest Pacific Ocean and the Indian Ocean is: from Sumatra Island to Timor Island via Java Island, then to Cape Delhi, Australia via Timor Sea, then from southern Australia via bass strait, and from Tasmania to the Antarctic continent.

The Pacific Ocean is vast, and the water in the deep sea is dark blue. As we approach the edge of the sea, the color of water changes from deep to shallow, and gradually becomes dark blue-light blue-dark green-green. In fact, it is also a visual experience of the process of ocean shallowing.

The Pacific Ocean is rich in products, from energy to minerals, from marine animals to marine fish. It is the most active Asia-Pacific economic cooperation organization in the world and the highest-level intergovernmental economic cooperation mechanism in the Asia-Pacific region. Every year, the heads of state of the Asia-Pacific Economic Zone hold a grand APEC meeting.

200 1 10, APEC meeting was held in Shanghai, China. This is the first APEC meeting held in China. In 20 14, APEC meeting came to China again after 13. As of September 20 14, APEC has 2 1 full members and 3 observers.
