Yesterday I measured Secchi disk transparency and compared that with simultaneous photometer measurements in a subtropical estuary. The lower border of the photic zone (1% of surface irradiance) according to my YSI photometer was at a depth of 4.7 m , while Secchi reading was at 1.6 m. Multiplying 1.6 by 2 gives 3.2, which is significantly lower than 4.7 m. Before that observation I believed in the "double-Secchi rule".

How deep is the oceans photic zone?
Photic - light; photic zone - light falling zone. Depth of photic zone refers to the distance travelled by sunlight in to the depth of the water and enable photosynthesis. It is measured using SECCHI DISC or photometer. Depth of photic zone is influenced by turbidity. It includes atmosphere-water surface to the depth where the total penetrating light intensity falls by 1%. This zone is a zone of productivity.
Why is life abundant in the photic zone?
Life is abundant in the photic zone for one very big reasons. The temperature of this location was warm and supportive of life.
What adaptations do plankton have to help them avoid sinking below the photic zone?
What adaptations do plankton have to help them avoid sinking in the photic zone ?
What plants and animals live in the photic zone?
Euphotic zonethe zone of water that is penetrated by sunlight, Phytoplackton make up its primary inhabitantshttp://content.answers.com/main/content/wp/en-commons/thumb/2/23/150px-Phytoplankton_SoAtlantic_20060215.jpgthis is a picture of a plankton bloom
Do any abyssal zone animals go to the photic zone?
yes

What determines whether a zone is photic or aphotic?
The aphotic zone is formally defined as the depth beyond which less than 1% of sunlight penetrates.
What is the well lit upper layer part of the ocean is known as the?
photic zone.
What type of animals live in the photic zone?
The uppermost layer of the world's oceans that receive sunlight during the daytime is called the photic zone. The depth of this zone depends on the clarity or murkiness of the water. In clear water, the photic zone can be quite deep; in murky water, it can be only 50 feet deep. On average, it extends to about 660 feet. Animals that live in the photic zone are plants, such as free-floating algae, sea weeds, etc. Zooplankton, most ocean fish, sea turtles, seals, etc. Bottom-dwellers such as starfish and sea shells live in the photic zone too. This zone is defined in terms of light, not depth.
Is the Photic zone in South America?
The photic zone is the depth of the water in a lake or ocean, that is exposed to sufficient sunlight for photosynthesis to occur. So you could say that it is all around South America, and on it where there are lakes and ponds.
At what depth does light fail to penetrate water?
The upper 100 -200 m of the ocean is called the Photic zone (photo = light).At about 150 meters 99% of light is absorbed.Beyond the Photic zone, light does not penetrate, and it is pitch dark.
What is the photic zone of the ocean-?
The photic zone of the ocean is the surface of the ocean that receives sunlight.
Portion of the marine biome that is too deep for sunlight to penetrate?
I dont know i want to know the answer myself
What distinguishes the photic zone from the aphotic zone in an aquatic zone?
Photic = where there's light Aphotic = where there isn't light, deeper waters.
Which ocean zone does sunlight penetrate?
The epipelagic zone is the region in the ocean that is exposed to a sufficient enough amount of sunlight to allow photosynthesis to occur.
Phytoplankton is most frequently found in which zones?
photic
What distinguishes the photic zone from the photic zone in marine ecosystems?
photic and aphotic derive their names fron the root word photo means light that is photic and aphotic zone differ each other in amount of light reaching there photic zone is directly lit up by by solar energy while aphotic zone is perpetually dark inhabiting least amount of floran fauna
