Burning Fossil Fuels in the Ocean
The process of ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulates in the atmosphere, where it causes global warming. But it also affects our oceans. As carbon dioxide enters the ocean, it reacts with seawater to form carbonic acid. This then kills most of the animals in the ocean which can lead to extinction. -

Increased Carbon Dioxide
the amount of carbon dioxide in the atmosphere rises, the oceans absorb a lot of it. Things like ships, cars, planes, trains and subways are good examples of things that produce carbon dioxide in the atmosphere. This then goes into the ocean, carbon dioxide reacts with seawater to form carbonic acid. This causes the acidity of seawater to increase which then harms animals like sea urchins to make their shells. -
Dissolved Carbon Dioxide decreased pH of the Ocean causing Acidification
Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed in the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean. This isn't a good thing for all of the animals that live in the ocean. -
Ocean Acidification damaged corals and other calcifiers weakening their shells, preventing their growth, and causing them to die.
Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. Animals that produce calcium carbonate structures have to spend extra energy either repairing their damaged shells or thickening them to survive. Some animals can't repair or thicken their shells or skeletons because of low energy or them being on the verge of death. -
Introduction
This is the introduction of the Trends of the Ocean by Jahan B. Sarshar.
Abiotic factors of an ecosystem: Water temp,Sunlight, moisture, wind currents, water currents, and soil type.
Biotic factors: Fish, turtles, dolphins, crustaceans, human activity, and coral polyps. -
Summary Pt.2
These animals also have an effect on animals outside of the oceans. Animals like coyotes can have problems with carbon dioxide in the air. This can affect the coyote's sense of smells and they might not be able to find their prey. It is normally common sense that if you can't eat you don't have energy and if you don't have energy you can't survive. -
Summary
The trends in the ocean are affected by many things, there are things like boats, cars, planes, trains, etc... These things increase the carbon dioxide levels that then increase the acidity levels. This can affect the animals in the long run, like how normally sea urchins live for up to 400 years but if the levels kill them off they can only live up to at least 350 years because they can't handle the levels. Some sea urchins have the energy to thicken or repair their shells.
