The intensity of sunlight, or irradiance, is an important factor for primary production in the ocean. Irradiance is measured in photons arriving per square meter per second, and varies depending on the time of day, the season, and weather conditions. The photic zone is that portion of the ocean that receives sunlight. Only low levels of light reach the deeper layers of the ocean because most of the light is absorbed by algae just below the surface and as depth increases light is absorbed by the water itself. When fewer algae are present, the photic zone extends deeper. The depth of the photic zone can also be affected by seasonal mixing of ocean waters. In the spring, for example, deep water is circulated toward the surface reducing sunlight penetration due to suspension of particles from the bottom. Most primary production occurs within a depth of 200 m.

Why the coin was seen when water is poured into the transparent cup?
When water is poured into a transparent cup with a coin at the bottom, the light gets refracted as it passes through the water and into the air, causing the coin to appear raised and no longer hidden by the water. This phenomenon is called refraction and it makes the coin visible even though it's at the bottom of the cup.
Where is the coldest water in the ocean?
The coldest water in the ocean is the bottom of the ocean.
Is water a transparent object?
Yes its blue in the ocean because of the particles floating around and the ocean. Water is clear by itself
Is there air on the bottom of the ocean?
No. There is water at the bottom of the ocean. There is oxygen in the water that a fish can breath in through it's gills.
Is the titanic still in the bottom of the ocean or has it been lifted out of the water?
The Titanic is still at the bottom of the ocean.
Why doesn't the bottom of the ocean freeze?
The bottom of the ocean doesn't freeze because water is a good insulator and the Earth's core heat keeps the ocean water from freezing.
Why is there fresh water at the bottom of the ocean?
There are fresh water lakes
Where would a anchovy live?
in brackish waters with good mud at the bottom not in very cold water not in very warm water basically and ocean,bay,stream,and river though
The arrangement of water masses in the southern Atlantic Ocean from the surface to the bottom is?
The arrangement of water masses in the southern Atlantic Ocean from the surface to the bottom is Antarctic Intermediate water, north Atlantic deep water, and the Antarctic bottom water. The location where water flow uninterrupted between the Pacific, the Atlantic, and the Indian Oceans is in the southern ocean.
Where can light not travel?
Through solid matter and certain other things in the other phases.Answer:Visible light cannot travel through opaque materials. However enough thickness of any material can eventually block out light. As an example, even though sea water is transparent, the bottom of the deep ocean is dark as light is incapable of reaching through miles of water
Environment of a starfish?
bottom of sea/ocean in water
What refers to the bottom of the ocean?
Benthic, it pertains to the botoom of the ocean or any body of water.
