Today, this presentation will talk about how ocean acidification is affecting our marine ecosystems and how it is affecting human life and how it can cause future problems for both ecosystems. Our main ecosystem focus is Alaska. At the end of this we hope that the information that has been given to you encourages you take more notice to the ocean acidification problem in our marine areas.
There are very few factors that go into the cause of ocean acidification. The main one ones are the increase dioxide in the atomsphere as well as other greenhouse gases.
Ocean Acidification: Alaska
Scientists estimate that oceans are 25% more acidic than they were 300 years ago. Due to increasing levels of carbon dioxide because of fossil-fuel combustion and land-use change. Alaska is very prone to acidity due to its relatively shallow shelf seas, cold water, high rates of primary production and glacial melt.
Ocean Acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.
Affect on organisms
Increasing ocean acidification has negatively impacted calcium shelled organisms. Causing their shells to dissolve and reduce the ability of reef-building corals to produce skeletons
The keystone species in this environment is the sea otter. Without the sea otter, herbivorous invertebrates are left to eat unclean kelp that releases carbon. Based on calculations, areas with more sea otters had more kelp that did not release carbon and throws off the balance of the ecosystem.
The "Call to Action"
Their is a drop in pH level of the ocean, shells, like crawfish dissolve, reduce ability of reef-building corals to make skeletons
OUR BELOVED CLIENTS
Once the funding is taken care of, we can use some of that funding and research to protect these animals by making a water capsule that not only cleanses water but the organisms. One compartment gently rinses the organisms through and gives them a gentle push back into the ocean. The other compartment is for water purification, which is your basic water filter that does NOT suck up the organisms because the sifts are too small, and only catches unwanted materials or chemicals in the water, helps control and monitor pH levels in the water. This filter is about the size of an 8 year old child, and are cleaned twice a month. They are distributed throughout the sea as often as cleaned.
A solution to reducing the acidification in the seas of Alaska would be first to fund for more research for the more technical ways that specific organisms are affected. Which can round up to about 1.5 billion.
What should motivate you to want to be apart of this change is how rapidly this is affecting killing off sea life. Overall seas have increased 25% in the last 300 years which is especially dangerous for sea life in Alaska since their seas are more shallow, the temperatures are colder, and since glaciers are melting. Alaska is one of the popular places for ice fishing. Think about standing on that fresh ice that's actually filled with carbon and acidity along, while hoping and wishing that you catch a huge fish for pictures, when really the bodies and gills are filled with water that is filled with acidity, carbon, and crazy pH levels, doesn't make ice fishing seem as fun huh?
The point is, everything is so much better and much more fun when it's clean and you're doing it efficiently and harmlessly. Everything's better when it's nice and clean.
