In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, that are derived from terrestrial environments.(Pinet, 79) Consisting of sand, mud, and silt carried to sea by rivers, their composition is usually related to their source rocks; deposition of these sediments is largely limited to the continental shelf.(Pinet, 79-83) Thermohaline circulation Oceanography (from Ocean + Greek γράφειν = write), also called oceanology or marine science is the study of the Earths oceans and seas. ...
