Oxygen compounds marine organic matter

The distribution of trace organic compounds such as chlorobiphenyls (CBs) and polycyclic aromatic hydrocarbons (PAHs) in seawater and marine particulate matter is determined by the complex influence of physical, biological and chemical processes. The interpretation of horizontal and vertical distribution patterns of these substances requires information on the corresponding characteristics of the water bodies, e.g., temperature, salinity, depth and the concentrations of nutrients and dissolved oxygen. 

Crude petroleum is a liquid that consists of hydrocarbons, as well as some related sulfur, oxygen, and nitrogen compounds. Other elements, including metals, may be present in trace amounts. Crude oil is formed by the decay of marine animal and plant organisms that lived millions of years ago. Over many millions of years, under the influence of temperature, pressure, catalysts, radioactivity, and bacteria, the decayed matter was converted into what we now know as crude oil. The crude oil is trapped in pools beneath the ground by various geological formations.
