Chemical oceanography deals with the study of ocean chemistry, more precisely, the activities of the chemical elements in the world's oceans. The ocean contains almost the entire elements in the periodic table. The main focus of chemical oceanography is to illustrate the biogeochemical cycling of these elements occurring within the ocean. These cycles are typically characterized by the quantitative fluxes between constituent reservoirs within the oceans and as residence times within the oceans. Carbon, nitrogen, and phosphorus and few vital trace elements such as iron are of particular global and climatic importance. Isotope geochemistry is another very important field of learning in chemical oceanography in which they are used as tracers of past and present oceanographic and climatic processes, e.g., the occurrence of 18O could be used as an indicator of polar ice sheet coverage, and boron isotopes are important indicators of pH and CO2 content of oceans in the geologic past.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
