Country Profile: Pacific Ocean
The Pacific Ocean, the largest of the world's ocean basins, spans an impressive area of approximately 168.723 million square kilometers, making it about 15 times the size of the United States. This vast body of water plays a crucial role in global climate patterns and trade routes, featuring strategically significant waterways. The ocean's diverse ecosystems are home to a variety of marine species but face challenges due to pollution and overfishing. Governed collectively by numerous countries, the Pacific Ocean is also historically rich, having been named "Mar Pacifico" or "peaceful sea" by the Portuguese explorer Ferdinand Magellan.
Geography
The Pacific Ocean is situated between the Southern Ocean, Asia, Australia, and the Western Hemisphere, and is characterized by a variety of geological features including trenches, ridges, and atolls. It covers about 28% of the Earth's surface and is home to the deepest natural point on the planet, Challenger Deep.
- Area: 168.723 million sq km
- Coastline: 135,663 km
- Mean Depth: -4,080 m
- Highest Point: Sea level
- Lowest Point: Challenger Deep at -10,924 m
- Volume: 669.88 million cu km (50.1% of World Ocean total volume)
- Seismic Activity: Contains about 75% of the world's volcanoes and 90% of earthquakes
Environment
The Pacific Ocean faces significant environmental issues, including pollution, habitat destruction, and overfishing, putting pressure on its diverse marine life. Climate changes, such as sea level rise and ocean acidification, impact ecosystems and the fishing industry. The fisheries in this ocean are the largest in the world, contributing to a substantial percentage of global marine capture.
- Fisheries Contribution: 58.1% of global marine capture in 2020 (45,800,000 metric tons)
- Major Fishing Regions:
- Northwest Pacific: 24.3% of global catch
- Western Central Pacific: 16.8% of global catch
- Southeast Pacific: 10.7% of global catch
- Endangered Species: Dugongs, sea lions, sea otters, seals, turtles, and whales
- Pollutants: Sewage, nutrient runoff, plastic waste, oil spills
