Εver wondered how deep the sea is? How far down you could swim and how much more there is left to reach the bottom?
There were a number of occasions were i was really curious to know whats the deepest point of the sea in general, I mean, did we manage to 'find' it? And if we did, how could we be sure that we actually did find it?
Questions like this made me to start digging for information regarding the depth of the sea, how deep we managed to go and how much deeper it could go according to estimates and hypothesis. What kind of life, what kind of sea species are living there? Below you will find an interesting picture showing a couple of examples:
1. Human diving
Depending if it is free diving or scuba diving, limit is 145m (475 ft)
2. Submarine (military type)
Its limit is around 900m (2950ft). Now i guess there might be some small differences depending on the 'model' or the evolution and the technology, but i guess this would be an average.
3. Whales
Since there are so many different whales, i used the example of Sperm Whale (Cachalot) and it can reach 1150m (3773 ft)
4. NR-1(Nuclear Research Sumbarine)
This was a research type submarine, used to map ancient coral reefs, gather samples, recoveries and repairing objects in the ocean. Its limit would be around 1500m (4500ft)
5. Titanic's wreck
From the headline, this one is easily understood. Titanic's remainings were found at 3810m (12500ft)
6. Deepest Recorded Fish
According to Nasa's seawifs website, the deepest recorded fish was found at 8370m (27,460ft). Unfortunately, no name was provided, so i checked what was the fish that used to have the 'record' before that, and it was snailfish in the Pacific Ocean, found its picture on Daily Mail's site:
7. Amphipod
It seems that many ampipods can go up to 9789m (32.199ft)
8. Bathyscaphe Trieste
Bathyscaphe Trieste is a two manned vessel (Swiss-designed and Italian built) that managed to reach 10912m (35802ft). It was the first manned vessel that managed to reach the bottom of the Challenger Deep, the deepest known point in Earth's seabed hydroshpere.
Note 1:
Director James Cameron almost reached the same point like the Bathyscaphe Trieste in 2012 as a challenge mission.
Note 2:
After 1000 meters(3280 ft), we are so deep in the sea that everything is dark, since sunlight can't reach anything beyond this point.
Note 3:
It is considered that there is over a thousand species that mankind hasn't been able to discover yet in the sea.
There is a nice video that shows many of those details, for whoever enjoyed the topic, here it is:
P.S
What do you think about my first steemit picture edit?
