# 3 Can Ocean Currents affect why organisms migrate and live in the specific geographical regions?

Currents affect living organisms by influencing food supply, water temperature and weather patterns. The three main causes of currents in the ocean are winds created by the earth's rotation and density differences in the ocean waters. So how are ocean currents playing a role in influencing where organisms live? The answer is a link that all organiss are interconnected together by in an ecosystem. The food chain! Currents are responsible for transporting nutrients and plankton from one area to another. An example is when fish heavily populate locations that have good food resources such as plankton, attracting larger predators such as tuna, birds and marine mammals and finally humans migrate to the nutrient rich environment. When warm water currents reach South America, plankton die because of the lack of nutrients in the warmed water current forces fish, such as anchoves to scatter to find food. This is an example of an ocean food chain that has been disrupted by ocean currents. Imagine this occurring daily in the most diverse part of the planet's oceans. In addition, ocean currents can slow down migration or speed it. It influences where plants and animals live and ultimately affects the settling of people in geographical, food rich, regions. When all is said and done, currents move our nutritional resources and heterotrophs must migrate to better resources. This is an simple explaination of how diverse life is on earth and how it's very success is driven by cycles occuring in the our ecosytem. We are all interconnected between living and non-living influences and currents make a gigantic influences on how and where organisms live successfully.

# 2 Willl Seasons be affected by Ocean Currents


Ocean currents affect seasons by changing the composition of the atmosphere, the output of the sun, and changing positions of continents and ocean currents. For example, the onset of the Indian monsoon can be timed with the first uplift of the Himalayas which drives it. Climate has not remained constant over a geological time scale and that is why slight changes of the suns wavelength, geographic location and wind driven currents make it predictable that the ocean currents have a direct impact on our climate. It is clear that even individuals have recognized the "unseasonable" weather patterns we are experiencing today. Seasons are no longer "set in stone" on our calendars. Some seasons are extremely longer than past recorded dates and others seemed to have been skipped altogether. Will we accept changes in a calendar year easily? I think the shift will be difficult and challenging yet still somewhat predictable for short term purposes.

# 1 How does weather affect ocean currents?


Two types of ocean currents affect climatic conditions. Deep water and surface currents provide the force to drive winds that that push warm and cold air masses. This is the major driving force creating our weather patterns. Warm equatorial currents drive toward the poles to colder temperatures and bring it back to the warmer equatorial climate. The two currents create our weather patterns because if forces warmer air masses to rise and ride over the denser cold air masses allowing movement of air with different temperatures to interact and create daily weather patterns. Surface currents are mainly influenced by wind, tides, waves and other environmental events. About a hundred meters down in the ocean you would be entering the waters known as deep water. Weather can also affect the waves of the ocean by unequal heating in the ocean. The Water Cycle plays a role by the process of precipitation. Just this slight change causes water movement forcing denser water to sink and warm water to rise generating wave action. In addition, ocean currents are affected by the distribution of the sun rays that provide the energy to move and drive global weather patterns.

Hey, welcome to my blog! :D

Hello, this blog is going to be about the ocean currents and how the weather effects them and how it helps to form most of our ocean currents. My title is "Surfs up! well maybe not." The reason why I named it that was because most ocean currents have massive waves when there is a change in the weather. Stay tuned because I will be posting more information about ocean currents and the change in weather and how they effect our climate. Hope you comment soon!! :D
Thank you :D
