The carbon and nitrogen content of marine Sedimente is associated with processes such as rates of sedimentation, and environmental aspects of deposition and diagenesis. Information on the distribution of these elements is also pertinent to the evaluation and reconstruction of past environments. It is thus necessary that we have a more thorough understanding of the relationship between carbon and nitrogen in sedimentary materials. The logarithmic relationship of carbon and nitrogen for sixty-five samples of near-shore marine Sedimente, both surface and subsurface, has been examined. The resulte are, compared, using data from various sources. Carbon and nitrogen show an approximately logarithmic linear functional relation. For both surface and subsurface samples the statistical C / N ratio may increase or decrease with increasing organic content. The slopes of the least-squares lines, representing this relationship, range from 0.09 to the vertical. Sedimente obtained from a Maine fjord indicate that the carbon-nitrogen association for surface and subsurface samples are quite different. The organic supply and environment of organic decomposition appear to be the primary factors controlling the ratio of carbon to nitrogen loss. The particular type of relationship between carbon and nitrogen in marine Sediments varies considerably. Consequently data from different areas must be treated separately.
