Geosciences conjointly referred to as oceanology and marine science, is that the branch of natural science that studies the ocean. Geosciences covers a large variety of topics as well as marine organisms and scheme dynamics; ocean currents, waves, and geology fluid dynamics; tectonics and therefore the earth science of the ocean floor; and fluxes of assorted chemical substances and physical properties among the ocean and across its boundaries. The study of the oceans is joined to understanding international climate changes, potential warming and connected part issues. The study of Geosciences is split into branches: Biological earth science investigates the ecology of marine organisms within the context of the physical, chemical, and earth science characteristics of their ocean surroundings.
High-impact journals are those considered to be highly influential in their respective fields. 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.
