Life in the Ocean Article
A: Major Points
-71% of the earth’s surface is covered in water
-Water compromises more than 90% of the biosphere volume
-Water covers 360 million square kilometers
-Sea slowly being explored
-10% of the ocean has been studied
-1% of the deep ocean floor has been studied
-Marine animals have greater diversity than land animals
-Only 250 thousand species have been identified in the ocean
-There are approximately 400,000 to 450,000 species
-This number could rise in the future
-Seawater is 800 times as more dense as air and more vicious
-Most animals stay fixed grazing on the food around them
-Total terrestrial species ranges from 5 million to 50 million
-1 to 10 million benthic species have not been described
-A cubic meter of soil yields 50 kg of organic matter per year while, a cubic meter of seawater yields 5 g
-Water absorbs light differently; Shorter wavelengths( blues and greens) penetrate more deeply than the longer wavelengths (reds and yellows) do. So the view 10 meters below the surface is mostly blue.
-100 meters below the ocean there is no light, no photosynthesis
-The deep ocean is rarely depleted of oxygen
-Oxygen minimum occurs at the depths 500 and 1,000 meters below the surface
-Every 10 meters of water/atmosphere
-At 1 kilometer the atmosphere’s pressure is 100 times what people experience
-In the deepest trenches the atmosphere’s pressure is 1,100 times what people experience
-The marine snow or shower of organic particles feed organisms in the deep ocean
-There are less consumers at lower depths
-Ocean animals have some of the longest migrations
-Ocean communities and creatures near the shore are well known
-These areas only make up 1 percent of the sea floor
-Marine ecosystems have been left out of discussions of saving biodiversity
-Fisheries are being operated at or beyond sustainable levels
B: Summary
The ocean makes up 71% of the earth’s surface and covers 360 million square kilometers of the earth. This leads to only 10% of the ocean has being explored. The ocean is extremely diverse and different compared to ecosystems and creatures on land. For every 10 meters is a different atmosphere. At 1 kilometer the atmosphere is 100 times what we experience but in the deepest trenches in the ocean the atmosphere is 1,100 times what we experience. These conditions are the reason why the deep ocean remains unexplored and is often out of discussion for protection. Since the biodiversity of these ecosystems are ignored, problems that arise are often not paid attention to. There is a lot more to the ocean than what we know and it is important to know about the biodiversity and ecosystems in this ocean so we shouldn’t disturb the ocean like what we (humans) are currently doing.
C: Reaction/Reflection
After reading this article I learned more of the difference between ecosystems on land and in the ocean. Earth supposedly should be called Oceanus since its surface is 71% water or has 360 million square kilometer of water on the surface; however I think that would be a rip-off of Neptune. This affects me because the ocean is on the planet that I live on and a lot of my needs are supported by factors that the ocean brings us like food. I believe that the ocean can be easily “fixed” if we just weren’t ***holes to it by using it a sewage drop-off and making it absorb all of the carbon we produce from industrialization.
So What?
The ocean is the most diverse place on the planet and is called home by many species we haven't identified
Says Who?
James W. Nybakken and Steven K. Webster
What if?
What if the entire ocean has been explored, and we found out that the deepest part of the ocean actually still contained ancient aquatic life.
What does this remind me of?
This reminds me of plainly the Earth itself, since we barely know all of things on it yet we assume that we understand some of it.
