The Ted ED video was very interesting. What struck me the most is how the earths ecosystems are all dependent on the deep sea current patterns. This is something that I had never learned about. Here are some of the things I learned: A gyre is a big loop in surface currents that travel clockwise in northern hemisphere and counterclockwise in the southern hemisphere. This natural phenomenon makes air traveling north in the northern hemisphere to deflect eastward and air traveling south to deflect westward this is the opposite in the southern hemisphere. This wind pushes currents and due to the properties of heat retention in water, this helps to distribute heat. Thermohaline circulation is caused because near the poles there is colder water and when the ice freezes it holds on to salt which makes it more dense and sinks; this frozen water gets replaced by warmer water. Thermohaline circulation and surface currents combine to form the global conveyor belt. This conveyor belt is the longest ocean current known to man and travels throughout the globe. When the warm water rises, it carries micro-nutrients helps to start the food chain in ocean ecosystems. This conveyor belt moves very slowly (a couple inches per day) rising temperature cause the conveyor belt to slow down which alter weather patterns, food distribution, and heat dilution. A couple questions I have from this video are: Why does rising ocean temperatures make the conveyor belt move slower? If frozen water is more dense and thus sinks near the ice caps, why does ice in a cup of water float? How deep do ocean currents affect? If the earth warms to a certain extent could the global conveyor belt cease to exist? This is a cool hole that I found at sunset cliffs. It was a very circular hole that had equally circular rings inside of it. I believe these rings were caused by periods of a lot of water and periods with no water. This could have been due to a storm or just the tides. I traced the image with a sharpie pen which is why the rings are not very circular. I then used Photoshop to color the rings and then put it on top of the original photo. This is some of the math that I have been working on this week. I am a little behind because of last week which is why the "differentiating logs is not completed but I will definitely have that done by next week. I am feeling confident in calculus right now even though I was gone for so long. I have been helping other people to understand how to solve some problems especially in the "Implicit Differentiation" worksheet.
Unfortunately we have not made very much progress on my personal project. I talked to Molly and she gave me a good idea for a project which is to pick a local fish and do multiple dissections on it and document the innards of the species. I think this is a more viable option. Also the reason that tagging sharks didn't work out was because we didn't have a boat that we could use and so we had to contact researchers to see if we could do our project with them. Unfortunately, not very many people responded so we were unable to continue with our project. However, I spoke with Bryan and he said that if I wanted to develop a tag this semester, We could go out on the blue dot boat during the summer and see if we could tag any sharks then.

Semester AzulThis semester I am in Semester Azul which is a class with around 20 students of all high school grade levels. We are exploring the vast mysteries of the ocean learning about the ecosystems, climate, and human influence. I hope you enjoy my progression!. Archives
