What Types of Soil Are in the Ocean?

The ocean floor is composed of three different types of soil, known as pelagic sediments or marine sediments. They include calcareous ooze, red clay and siliceous ooze.

The Ocean Floor

The ocean floor is made up of mountains, valleys, plains, plateaus, islands, ridges and volcanoes. The Earth's floor below the ocean is very similar the that above the ocean.

Ooze vs. Clay

Ooze is made up of debris from living organisms; any soil composed of more than 30 percent organic debris is classified as ooze, making it a biogenous sediment. Red clay is not organic; it's made of rock and is considered lithogenous sediment.

Calcareous Ooze

Calcareous ooze is the most common of the three soils and covers approximately 48 percent of the ocean floor. It is composed of the shells of foraminifera, coccolithophores and pteropods, which are tiny organisms living in the ocean.

Red Clay

Red clay covers approximately 38 percent of the ocean floor and is brown. It is made up of quartz, clay minerals and micrometeorites, which are rocks that weigh less than a gram and have fallen to Earth from outer space.

Siliceous Ooze

Siliceous ooze is the least common of the three soils, covering approximately 15 percent of the ocean floor. It is composed of plankton debris and silica shells.

“Somewhat Alive”

My intention is to create an experience that appears subtle while conveying a sense of power.
The draped fabric appears quite and subtle. The shades of pink create a monochromatic atmosphere
of fleshy life. The sheets are connected to an inner motor so that every few moments both forms
pulsate at their own rhythm. Sporadic thuds can be heard as the mechanism turns.This installation
creates a delicately engaging interaction with the viewer, as its calls attention to itself if the
viewer is willing to stop and experience the limited movement.

Materials:
Cotton fabric
Rotisserie chicken motors
Wood
Wire
