Deep sea Deep sea zones. The deep sea or deep layer is the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1000 fathoms (1800 m) or more. Little or no light penetrates this part of the ocean, and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone.

How far does light travel in the ocean? How far does light travel in the ocean? Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters. The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it. Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level.

Definitions &Translations Darkness, as polar to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space. Humans are unable to distinguish color when either light or darkness predominate. In the absence of light, perception is achromatic and ultimately, black.

If thereâs no light, there can be no photography; but what is light, exactly? Without going knee-deep into physics, light can be thought of as tiny particles that move very, very fast. Understanding light is vital to your understanding of photography. The more you know how it behaves, the better you can manipulate it to create photos. To start, weâre going to learn to identify âhardâ and âsoftâ light, terms youâll often hear photographers reference. Soft light. A large light source—such as light reflected off a large surface for example a ceiling, or the sun diffused by a layer of clouds—does the opposite: the light will be ‘soft,’ and the resulting shadows will be much softer as well.

Dispatches from the Deep: Light and Dark in the Sea In the aphotic zone; all that’s left of sunlight is a dim, dark, blue-green light, too weak to allow photosynthesis to occur. There is food to be had, though; detritus, bits of decaying plants, and animal waste falls from above to feed the organisms in the aphotic zone. After the aphotic zone, there’s complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either.

Q: Is darkness a wave the way light is a wave? What is the speed of dark? Physicist: The very short answer is no: darkness is not a wave. There are no waves in the dark for very much the same reason that there’s no surfing (or ocean waves) in Death Valley. Darkness, being an absence of electromagnetic waves (light) has nothing to do any waving.

How far does light travel in the ocean? The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet). Sunlight does not penetrate to these depths and the zone is bathed in darkness. ‘Photic’ is a derivative of ‘photon,’ the word for a particle of light.

- The average depth of the ocean is about 12,100 feet (3,688 m). The lowest ocean depth on Earth is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench.

Southern Ocean - Map & Details. The Southern Ocean has typical depths of between 4,000 and 5,000 meters (13,000 to 16,000 ft) with only limited areas of shallow water. Its greatest depth is measured at 7,236 meters (23,737 ft) at the southern end of the South Sandwich Trench, at 60°00'S, 024°W.

- For example, if a wave at the surface has a height of 4 meters and a wavelength of 45 m, then the depth where no motion from the wave exists is 45/2 or 22.5 meters.

Decompression Sickness (The Bends) Most dives encountered are termed no-decompression dives that means no decompression stop was necessary. However on ascent if the elimination of nitrogen fails to keep up with the pressure reduction then a point may be reached where the gas no longer stays in solution.

What's At The Bottom Of The Deepest Hole On Earth? For the next 24 years, they drilled on and off into the Earth’s crust. The result was the Kola Superdeep Borehole and a drill-depth of more than 7.5 miles (12 kilometers). To put that in perspective, Kola descends further than the deepest point of the ocean, which lies at nearly 6.8 miles (11 kilometers). The borehole is located on the Kola Peninsula of Russia.

- Operating at night (or in reduced visibility) can present some special challenges. Not only is your depth perception lessened, bright lights on the shore can cast misleading reflections on the water and if you wear glasses, or worse yet bifocals, you simply don't see as well at night as you do during the day.

Aphotic zone The aphotic zone (aphotic from Greek prefix ἀ- + φῶς without light) is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1% of sunlight penetrates. Consequently, bioluminescence is essentially the only light found in this zone.

- When I was a kid a pool without a diving board, is just as useless as a pool without water! Lib I am in favor of non-diving pools. We've had inground pools installed in our first home (1996) and present home (2004). The first pool had a traditional deep end, and our present pool is 6 feet at the deepest point. pool without a deep end is like going to a theme park that decided to forgo the roller coasters for a merry-go-round and a small slide. Oldtimer I have a 40' pool 91/2' deep. We have had the pool for 42 years and I now need a new diving board.

How long can you go without air? Then with a small splash, he dove under the water and began swimming down into the Dean’s Blue Hole – an underwater cave in the Bahamas. Mevoli’s goal was to reach a depth of more than 70 metres (230ft) – and do it on a single breath of air. It would end in disaster.
