What's at the bottom of the ocean?
Ninety-five per cent of the ocean is unexplored. What's down there? In 1960, Don Walsh and Jacques Piccard travelled seven miles down, to the deepest part of the ocean, in search of answers. Their voyage pushed the boundaries of human endeavour but gave them only a glimpse of life on the seafloor. It's so difficult getting to the bottom of the ocean that for the most part we have to resort to sending unmanned vehicles as scouts. The discoveries we've made so far – from bizarre fish such as the barreleye, with its transparent head, to a potential treatment for Alzheimer's made by crustaceans – are a tiny fraction of the strange world hidden below the waves.
What's at the bottom of the ocean?
Darkness! Because not even a fraction of sunlight reaches the depths. Since no light, no plants.Pressure! The water exerts tremendous pressure as u go deeper and at great depths of say > 1000 meters, the pressure is crushingCold! Lack of sunlight and the fact that water is a bad conductor of heat means the bottom layers of the ocean are very very coldOccasionally violent! The bottom of the sea represents the thinnest part of the earths crust and hence most prone to earthquakes, volcanoes, tsunamis etc.Rich topography! Mountains, valleys, rivers and beaches … each larger than their counterparts on the surface means a whole undiscovered planetLonely! The cold and dark means that except a few rare organisms like sponges that are specially adapted, there is practically nothing living at the bottom of the sea2 billion years from now when the sun starts cooling and expanding, it will have engulfed the earth but the heat would have melted the ice on moons like Titan providing mankind wit the next home. However, all such homes are likely to be water planets and how we adapt to living on and below the endless oceans on these planets will determine whether we continue to survive as a species.
What lives in the bottom of the ocean?
There are lots of things that live at the bottom of the ocean. These are called benthic creatures. The actual type of creature will depend on the depth. In very deep water as another post here indicates, there can be hydrothermal vents which supports communities using chemicals from inside the earth rather than sunlight and photosynthesis. These are quite rare though and most benthic creatures that live in deep water survive on detrital particles falling through the water column or by eating other things on the bottom. They need to do this because sunlight can only penetrate the first 50m of water or so. Deep water is very dark and photosynthesis isn't possible. Deep sea Benthic creatures include bacteria, fungus, and other microbes/ simple organisms, brittle stars, lampreys, molluscs, annelids, arthropods and coelenterates. There are also some very ancient types of shark and some deep sea fish. Unless something like a whale carcass falls to the bottom, it is considered a low energy environment.
Whats at the bottom of the ocean?
Because the ocean is sooo vast, we probably can't/won't explore it fully. There are a lot of mysteries and incredible discoveries every year. Like the thought to be extinct Coelacanth, which was thought extinct for millions of years until 1938... or mega mouth sharks... or sea life at the deepest parts of the ocean around the thermal-sulfur vents. The incredible discoveries are cool, but the size or awe factor isn't that life impacting. Giant squid can be huge, but they are NOT the monsters of story books. Aquatic life is limited to biological balances, like food-need, oxygen-need, heat, light, etc. Unfortunately, I don't think some giant squid is going to pull a large-boat down, or atlantis being active with mer-people. What is equally incredible is the fish with no predetermined growth size.... they can keep growing until their environment (food) balances them out. Or the life around sulfur vents...that seem, even to scientists, puzzling, due to the fact they shouldn't handle that much pressure, heat, chemicals, etc...which can translate to an alien environment off on another planet, which we thought was too harsh. I get excited by sea CREATUREs that use photosynthesis, they self feed off light like plants....that's awesome. Or ones that regenerate whole body parts. That's the mysteries I think will wow us, and change a lot of science like medicine etc. I'd love to be green with chlorophyll and be able to grow my arms back.
What is the bottom of the ocean called?
The Sea Floor or sometimes "The Abyss"
Have we reached the bottom of the ocean?
Well you need a submersible. I would suggest using James Cameron’s Deep Sea Challenger. He used it to dive into the Challenger Deep in the Marinas Trench. It is the deepest spot on earth at 6.83 miles or 36,070 ft. At that dept the pressure on the vehicle is 8 tons per square inch! It is a solo vehicle which can get you to all of the the ocean bottoms.As with spaceships, deep-sea submersibles must be engineered to accommodate innumerable challenges, including dramatic changes in pressure and temperature and a total absence of sunlight. In the process of meeting these challenges, the DEEP SEA CHALLENGER submersible engineering team has made historic breakthroughs in materials science, incorporated unique approaches to structural engineering, and innovated new ways of imaging through an ultra small stereoscopic camera capable of withstanding the pressure at full ocean depth. After reaching the seafloor, the DEEP SEA CHALLENGER was able to explore the bottom for several hours—dramatically longer than the 20 minutes U.S. Navy Lt. Don Walsh and Swiss oceanographer Jacques Piccard were able to spend there during their expedition in the bathyscaphe Trieste on January 23, 1960.Hope this helps my friend.Footnotes DEEPSEA CHALLENGE
What sort of sand is in the bottom of oceans?
It depends on where in the ocean you are looking. In shallow coastal waters, you have medium-grained sands and as you get a little deeper, it becomes fine-grained. This fine-grained sand transitions to silt as you get further from shore. Once you reach the edge of the continental shelf, you're talking clays and carbonate sediments now. In the really deep oceans your clays transition to siliceous and calcareous ooze. In the deepest depths of the ocean, calcium carbonate materials become unstable and you pretty much just have siliceous ooze and some weird clays that form very slowly (read the link below). And yes, ooze is the technical term.Pelagic sediment
What would the bottom of the ocean look like if all the water were taken out?
Several of the answers have dealt nicely with the matter of topography, making reference to the many mountain ranges, fault lines & trenches and their associated rift valleys and volcanoes.But, for all of the impressive highlands, much of the drained oceans would be fairly unimpressive to behold. Lots of broad, flat abyssal plains beyond the continental slopes. Furthermore, there would be a vast expanse of black organic mud across the abyssal plains; the accumulation of millennia of dying micro-organisms. It would stink, make no mistake. Organics at depth for ages, in virtually motionless conditions? The anaerobic conditions produce noxious, foul-smelling gases within the sediments, which one would be wise to leave undisturbed!Closer to the continental shelf, there would be coarser sediments along the base of the continental slope; turbidite deposits of mixed-up, semi-sorted sands, silts and clays. Cast down from the shelf above by earth tremors, these tumbled sediments get finer as they extend a short distance of a hundred miles or so from the top of the slope.Up on the continental shelf, fringing the drained oceans, would be yet more mud, but a slightly more pleasant mixture of silts and marine snow (dead plankton), along with the results of coastal erosion, tides and other dynamic events; the shelves are a much more interesting place than the plains, but perhaps only if you are a marine biologist or a geologist!Perhaps the most interesting aspect of the drained oceans, and one perhaps not immediately evident, is the total absence of hydraulically-formed watersheds. Total submergence for millions of years, during the formation & growth of the oceans, and during deposition of sediments, means that there has been no ‘run-off’ - no drainage - with the ocean basins themselves.This means that there are no river valleys whatsoever; the very things which define the ranges of hills that make our above-water landscapes so naturally familiar to us, wherever on Earth we are. It would be a strange-looking place, yet curiously boring for the average person to behold, I suspect.
What do you call 1,000,000,000 lawyers at the bottom of the ocean?
A good start
What sits at the bottom of the ocean and shakes a lot?
hahahahaha my friends saw this joke but we knew the right answer but we though of a different funny answer
