Basics of the Deep Sea
The deep sea section of the ocean is located in the Midnight zone; the lowest part of the ocean. It can reach 11,500 ft down at its lowest point. The average temperature in the deep sea is 39 degrees Fahrenheit. The pressure is 16,000 lbs per square inch down there. If you were to go there, it would be complete and utter darkness; seeing literally nothing because the sun is blocked by all that water. There are also lots of deep trenches down there that are the lowest points on earth. This section of deep waters is called the Mariana Trench.
Affects on the deep sea
Most things do not affect the deep sea due to its depth, but some things do. For example, near Antarctica, there is an up-welling. The up-welling brings algae to the surface and pumps up nutrients. But things such as the majority of currents do not affect the deep sea. And of course tides do not because those are right near the shore; started by wind which the deep sea does not receive.
Planning on going on a deep sea exploration? Think twice. Humans cannot go to those intense depths in the earth. That is why we do not know much about the ocean floor; because we cannot physically go down there. The animals down there? No thanks. Deep sea animals are definitely not your average marine animals. I personally would never want to be anywhere near a Giant Spider Crab, Fangtooth Fish, nor a Vampire Squid.
Now if you're still hooked on going down to the deep sea, you can go in a submersible. A submarine that can take you all the way down. You still can't stay too long though. So if you are, but sure to bring a flashlight, some clothes, and plenty of oxygen. Also, bring a camera to bring the dark sea to life when you gets back up to land.
Along with the up-welling, the deep sea hold a few invasive species including pathogens and parasites. There are also lots of materials we can get from the deep sea. Some of those include manganese nodules, cobalt, and lots of other metals. Now humans affect the ocean big time, no matter where you are. All our waste and car exhaust goes straight to the waters, killing off lots of animals.
a call for help
So how do we help these creatures whom we have destroyed. well for starters we can start many more MPA's who help the ocean animals. We can try our hardest to move to less cars, or cars that run off safer chemicals. That would help us all. And lastly, we can have safer environments for fishers so they don't ruin our marine life.
