The Ocean's Memory: Sediment Distribution Patterns
While sediments of all varieties can be found almost anywhere in the marine environment, there are some very distinct distribution patterns.
The Ocean's Memory: Biogenous Sediments
While most sediments are terrigenous, there are other sediments that are also found in the marine environment. Biogenous sediments are those that form from the shells or skeletons of marine animals.
The Ocean's Memory: Terrigenous Sediments
Sediment is the debris that accumulates on the surface of the Earth as the result of chemical, physical and biological processes. Most sediment, known as terrigenous sediment, forms when rain falls on soil and washes it into rivers, which then carry...
The Ocean's Memory: Sediments and Past Climate
As sediments get laid down, they carry with them a record of the kind of environment in which they were formed. Scientists can read that record and learn valuable information about past climate and temperature change.
