Why are Ocean Currents Important?

Types of Ocean Currents

Ocean currents are driven by a variety of factors, including tides, winds, and changes in water density. These factors work together to create a complex system that has a significant impact on our weather, marine travel, and oceanic ecosystems. Tides, which are caused by the gravitational pull of the moon and the sun, play a role in driving ocean currents. The rising and falling of tides create a rhythmic movement of water, contributing to the flow of currents. Winds also have a strong influence on ocean currents. Global wind systems, driven by the uneven heating of the Earth's surface, transfer heat from the tropics to the polar regions. This heat transfer creates pressure differences in the atmosphere, which in turn generate winds. These winds, known as surface winds, push the surface waters of the ocean, creating surface currents. In addition to tides and winds, changes in water density contribute to the formation of ocean currents. Variations in temperature and salinity, both of which affect water density, play a crucial role. This process, known as thermohaline circulation, drives deep ocean currents. In cold regions like the North Atlantic Ocean, differences in water density caused by variations in temperature and salinity are particularly important. It is important to note that ocean currents are not solely influenced by abiotic factors. Biological factors also come into play. The distribution of food and nutrients in the ocean can be influenced by ocean currents, which in turn affects marine ecosystems. In conclusion, the driving forces behind ocean currents are diverse and interconnected. Tides, winds, and changes in water density all contribute to the complex system of currents that shape our planet's climate system and support marine ecosystems.

The Great Pacific Garbage Patch

This collection of litter (composed mostly of tiny pieces of plastic) is located in the North Pacific. The trash is collecting in the calm center of the North Pacific Subtropical Gyre. A gyre is a large system of swirling ocean currents. The North Pacific Subtropical Gyre is made of four separate currents: the California current, the North Equatorial current, the Kuroshio current, and the North Pacific current. These four currents are moving large amounts of trash towards the Great Pacific Garbage Patch — helping it grow ever larger.

To Understand Ocean Currents, it's best to start with understanding the waves. and how it plays a large role in creating energy.

The five major oceans wide gyres are the North Atlantic, South Atlantic North Pacific South Pacific, Indian Ocean, Ocean gyres and world map pacific of plastic pollution. The currents we see at the beach are called coastal currents that can affect land and wave formations. Currents travel around 5.6 miles per hour in warmer waters of the northern hemisphere and in the North Pacific moves much slower in cold water at 0.03 to 0.06 miles per hour.

Currents & Marine Organisms

Ocean currents exist both on and below the surface. Some currents are local to specific areas, while others are global. And they move a lot of water. The largest current in the world, the Antarctic Circumpolar Current, is estimated to be 100 times larger than all the water flowing in all the world’s rivers! All of this moving water helps more stationary species get the food and nutrients they need. Instead of going looking for food, these creatures wait for the currents to bring a fresh supply to them. Currents also play a major role in reproduction. The currents spread larvae and other reproductive cells. Without currents many of the ocean’s ecosystems would collapse.

What Can You Do?

Cleaning up the Great Pacific Garbage Patch is a challenge. It is not close to any coastline, which means no one country or organization has stepped up to take responsibility for its cleanup. However, many ocean conservation organizations, such as Ocean Blue Project, one of the best Ocean cleanup organizations removing 1 million pounds of plastic by 2025. Help save our blue economy by making a one time donation to help remove plastic pollution from a beach near you.

The best way to support this effort — reduce your use of single-use plastics. If less plastic is being used, then less of it will end up in our oceans.

What are the Five Oceans of the World?

"The Five bodies of water and the global ocean produces more then half oxygen humans breath."

Historically the Ocean was thought of having 4 oceans the Pacific, Atlantic, Indian, and Arctic. Today we have Five Bodies Of Water and Our One World Ocean or Five oceans AKA Ocean 5, and two seas covering over 71 percent of the earths surface and over 97 percent of the earth’s water. Only 1% of earths water is freshwater and percent or two is part of our ice glaciers. With sea level rise just think of our ice melting and how a percent of earth would so be under water. The oceans of the world host over 230,000 marine animals species and more could be discovered as humans learn ways to explore the deepest sections of the ocean. We all share the same ocean our one world Ocean, learn more about how we can protect the microplastics that are harming fish and how we can support the ocean cleanup.

Antarctic Ocean

The Southern Ocean also known as the antarctic area.

The Antarctic ocean is the smallest of our oceans and the fourth largest and is full of wildlife and mountains of ice lastly throughout the year. Although this area is so cold humans have managed to live here. One of the largest setbacks is with global warming most of the ice mountains is expected to melt by 2040. The depth of The Antarctic Ocean is 23,740′ in depth. The Southern Ocean also known as the Antarctic Area: 7.849 million mi².

How many people live in the Antarctic? No humans live in Antarctica permanently, but around 1,000 to 5,000 people live through the year at the science stations in Antarctica. The only plants and animals that can live in cold live there. The animals include penguins, seals, nematodes, tardigrades and mites.

Indian Ocean

Fun facts: Between Africa and Austral

Indian Ocean is located between Africa and Austral-Asia and the Southern Ocean. is the third largest of our oceans and covers a fifth ( 20%) of our earths surface. Until the mid 1800s the Indian Ocean was called the Eastern Oceans. The Indian Ocean is around 5.5 times the size of United States and is a warm body of water depending on the Ocean Currents of the Equator to help stabilize the temperatures.

Atlantic Ocean

Atlantic Ocean boards North America, Africa, South America, and Europe. This Ocean is the second largest of our five oceans and home of the largest islands in the world. The Atlantic Ocean covers 1/5 of the earths surface and 29% of the waters surface area.

The Atlantic Ocean ranks the second for the most dangerous ocean waters in the world. This ocean water is usually affected by coastal winds, temperature of the water surface currents maps.
