Ocean 540: Marine Sedimentation. --Marine Geological Processes--Autumn Quarter 2002. Overview of Marine Sedimentation. The term sediment refers to material composed of particles that have settled to bottom of a liquid. Sediments are classified by the processes involved in determining their physical and chemical character.

Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can show inflammatory activity in the body. Many health problems can cause a sed rate test result to be outside the standard range. A sed rate test is often used with other tests to help your health care team diagnose or check … See more

Sedimentation is affected by particle concentration. From everyday experience, the effect of sedimentation due to the influence of the Earth's gravitational field (g ¼ 981 cm s −2) versus the increased rate of sedimentation in a centrifugal field (g > 981 cm s −2) is apparent.To give a simple but illustrative example, crude sand particles …
