The Deep Sea
By: Tracy Tran
What You Need To Pack
What you need to be prepared for:
The average temperature: about 4-10 degrees Celsius (depends on where in the twilight/midnight zone you are)
Things that will be provided:
-A submersible that can withstand high pressure
-net to catch small life forms
Things you'll need to bring
-some form of entertainment, perhaps a book or game while you wait for the submersible to dive down
- any sort of materialistic necessity you may have (like phones to take pictures)
Ocean Floor Attractions
So what does the Deep Sea look like?
The Deep Sea is actually split into zones. The main zones are the twilight zone and the midnight zone. The midnight zone is farther down than the twilight zone and receives even less light! There's hardly any algae down here because of that!
Some examples of types of Animals in the Deep Sea: (Kingdom: Animalia)
Copepods- Phylum: Arthropoda, Class: Crustacea
Comb Jellies- Phylum: Arthopoda, Class: Ctenophora
Isopods- Phylum: Arthopoda, Class: Isopoda
Octopus- Phylum: Mollusca, Class: Cephalopoda
Cookiecutter Shark: Phylum: Chordata, Class: Chondrichthyes
Anglerfish: Phylum: Chordata, Class: Actinopterygii
There's a lot of darkness in the deep sea, since not a lot of light reaches down there. One of the main attractions are the animals with bioluminescence. These animals can light up, because they naturally produce light! Examples of animals with bioluminescence: Anglerfish, different Copepods, and etc!
Since you can't go to the ocean floor, you'll mainly see the interesting animals down the the deep sea.
The Science Section
The Deep sea is simply too far down to have any currents, and so the currents and gyres are on top of this zone.
Upwelling is when colder, more nutrient filled water rises to the surface. Upwelling effects the deep se because this is where the water is coming from.
Underwater mining is a huge resources in the Deep Sea! This is when people and companies mine underwater for oil and minerals.
We dive down to mine the oil and minerals in the deeper zones. We risk carrying deep sea invasive species to the surface.
How to Protect This Zone:
It's protected by the large amount of pressure and cold temperatures, however we could all do the ocean a favor and not throw our trash into it.
