photic zone

But plants, as we have seen, can grow only near the surface of the sea, in the photic zone.

Its origin lies in activities within the productive photic zone.

The photic zone covers the oceans from surface level to 200 metres down.

The photic zone can be subdivided into two different vertical regions.

In this way, a sample can be collected across the whole photic zone where most ichthyoplankton is found.

The pelagic part of the photic zone is known as the epipelagic.

This is also known as the euphotic, or more simply as the photic zone.

The photic zone has sufficient light for phytoplankton to photosynthese.

Day length and insolation intensity also controls the extent of the photic zone.

The photic zone exposed to sufficient sunlight for photosynthesis to occur.

The term deep sea creature refers to organisms that live below the photic zone of the ocean.

This limits phytoplankton photosynthesis to a relatively shallow photic zone.

The depth of the photic zone can be greatly affected by seasonal turbidity.

Because the photic zone typically extends only a few hundred meters below the water, about 90% of the ocean volume is in darkness.

Net photosynthesis in the water column is determined by the interaction between the photic zone and the mixed layer.

The depth to which sunlight or artificial light can penetrate into water, so that photosynthesis may occur, is known as the photic zone.

It is also referred to as the surface waters or the sunlit zone, and includes the photic zone.

The different fauna present in the Eagle Ford suggest the waters were calm and within the photic zone.

When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability.

The photic zone is defined as the surface waters down to the point where the sunlight has attenuated to 1 percent of the surface value.

Typically, each spring, the planktonic plants and animals in the surface photic zone do very well, feeding on nutrients at the surface.

For practical purposes, the thickness of the photic zone is typically defined by the depth at which light reaches 1% of its surface value.

Deep sea fish - Deep-sea fish is a term for any fish that lives below the photic zone of the ocean.

It is a significant means of exporting energy from the light-rich photic zone to the aphotic zone below.
