Intertidal and shallow sublittoral zones to a depth of about 10 m.

It occurs in the littoral and shallow neritic zone.

This limits phytoplankton photosynthesis to a relatively shallow photic zone.

The first, the littoral zone, is the shallow zone near the shore.

Others have shallow rooting zones and poor drainage due to subsoil cementation.

This process accounts for many of the shallow, abnormally pressured zones in the world.

Instead, they found a shallow zone of methane production.

In recent years at least the massive concrete walls alongside the river have been replaced in most of the shallower zones by large stones.

Their model shows a shallow zone where rocks, even boulders, can be kicked upward at high speed without ever feeling the full pressure of the wave.

Some species are found under rocks in the lower intertidal and shallow subtidal zones.
