Limnology is that the study of landlocked aquatic ecosystems. The study of earth science includes aspects of the biological, chemical, physical, and geologic characteristics and functions of landlocked waters (running and standing waters, contemporary and saline, natural and man-made). This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater. A newer sub-discipline of earth science, termed landscape earth science, studies, manages, and seeks to conserve these ecosystems employing a landscape perspective, by expressly examining connections between associate aquatic scheme and its watershed. Recently, the necessity to grasp international landlocked waters as a part of the world System created a sub-discipline known as international earth science. This approach considers processes in landlocked waters on a world scale, just like the role of landlocked aquatic ecosystems in international biogeochemical cycles. earth science is closely associated with aquatic ecology and hydrobiology, that study aquatic organisms and their interactions with the abiotic (non-living) atmosphere. whereas earth science has substantial overlap with freshwater-focused disciplines (e.g., fresh biology), it conjointly includes the study of landlocked salt lakes.

To increase the visibility and ease of use of open access scientific and scholarly journals top online publishing journals are indexed in different indexing and archiving services. Indexing provides easy access of the article online. The top online publishing journals publish articles which are cited as references by many authors in their work. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. Indexing provides easy access of the article online. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, relevant and reliable information based on the current research and development on a variety of subjects. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal.
