Marine sediments are composed of both biogenic and terrigenous materials.
Biogenic sediments includes the remains of planktic and benthic organisms,
which provide a record of past climate and oceanic circulation. Terrigenous
material provides a record of humidity-aridity variations on the continents,
intensity and direction of winds, and other modes of sediment transport
(rivers, glaciers, erosion, etc.).
