This course on Marine Sediments in Oceanography aims to teach students about the classification of marine sediments, paleoceanography, and the distribution of different sediment types in the ocean. Students will learn about the properties of sediments such as grain size, texture, and composition, as well as the environmental factors that influence sediment formation. The course covers various types of marine sediments including lithogenous, biogenous, hydrogenous, cosmogenous, and evaporites. The teaching method involves lectures on sediment classification, properties, and distribution, with a focus on understanding the geological processes that shape the ocean floor. This course is intended for students and professionals interested in oceanography, geology, environmental science, or marine biology.
Overview
Syllabus
Intro
Classification of Marine Sediments
Paleoceanography and Marine Sediments Paleoceanography - study of how
Lithogenous Quartz and Wind Transport
Grain Size One of the most important sediment properties Proportional to energy of transportation and deposition
Texture and Environment Texture indicates environmental energy
Biogenous Sediment Hard remains of once-living
Calcium Carbonate in Biogenic Sediments Coccolithophores
Distribution of Biogenous Sediments Depends on three
Neritic Deposits Dominated by lithogenous sediment, may contain biogenous sediment · Carbonate Deposits
Calcareous Ooze and the CCD Scarce calcareous ooze below 5000 meters (16,400 fot) in modern ocean
Distribution of Modern Calcium Carbonate Sediments
Hydrogenous Marine Sediments Minerals precipitate
Manganese Nodules Fist sized lumps of manganese, iron and other metals
Phosphates and Carbonates Phosphates - Phosphorus-bearing
Metal Sulfides Metal sulfides Contain
Evaporites Evaporites
Cosmogenous Marine Sediments Macroscopic meteor debris
Marine Sediment Mixtures Usualy mixture of different sediment types Typicaly one sediment type dominates in different areas of the Sea
