Geophysical Journal International

Geophysical Journal International is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Geophysical Journal International rather than just read about it. In short: Geophysical Journal International (GJI) is a monthly peer-reviewed scientific journal in the field of geophysics. It is published by Oxford University Press on behalf of two learned societies: the Royal Astronomical Society (RAS) and the Deutsche Geophysikalische Gesellschaft (German Geophysical Society, DGG), who select and peer-review the contents.

Geophysical Journal International belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Geophysical Journal International to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Geophysical Journal International (GJI) is a monthly peer-reviewed scientific journal in the field of geophysics. It is published by Oxford University Press on behalf of two learned societies: the Royal Astronomical Society (RAS) and the Deutsche Geophysikalische Gesellschaft (German Geophysical Society, DGG), who select and peer-review the contents. GJI was formed in 1988 by the merger of three earlier geophysics journals, the oldest of which was established in 1922. The editor-in-chief is Joerg Renner (Ruhr University Bochum). The journal publishes original research papers, research notes, letters, and book reviews. Its topical scope includes research on all aspects of theoretical, computational, applied and observational geophysics.

History GJI was formed by a complex series of mergers between previous geophysical journals. Its origins can be traced to 1919, when the RAS absorbed the Geophysical Committee (which had previously been part of the British Association), thereby becoming the learned society responsible for British geophysics. This led to an increase in the number of geophysical papers being published in the Monthly Notices of the RAS (MNRAS). In 1922 it was decided to separate the geophysical papers from those on astronomy, by issuing the Geophysical Supplement to Monthly Notices. These were not published on a regular schedule, but instead issued whenever a sufficient number of geophysical papers were ready for publication, and distributed to MNRAS subscribers. This arrangement continued for several decades, until the International Geophysical Year of 1957-58 brought renewed attention to the subject. This prompted the RAS to convert the supplements to a separate journal, which began publishing in 1958 as Geophysical Journal. In 1970, it established an office in the United States to handle the increasing number of submissions from North America. Meanwhile in Germany, the DGG was founded in 1922 and in 1924 began publishing the German language journal Zeitschrift für Geophysik (lit. Journal for Geophysics). From 1954 it was published in partnership with Physica-Verlag. In 1973 the publisher was acquired by Springer Verlag, who began including papers in English and changed the journal's name to the bilingual Journal of Geophysics – Zeitschrift für Geophysik. In France, the CNRS began publishing Annales de Géophysique (lit. Annals of Geophysics) in 1944. In Italy, the Annali di Geofisica (also lit. Annals of Geophysics) began publishing in 1948, by the Istituto Nazionale di Geofisica. These two journals merged in 1983, under the auspices of the European Geophysical Society (EGS), with the combined journal given the name Annales Geophysicae (the Latin translation of both names). In 1986 this split into two series, A and B, with content relevant to GJI being published in Annales Geophysicae, Series B: Terrestrial and Planetary Physics. Finally, these three branches of journals merged in 1988. The RAS's Geophysical Journal, the DGG's Journal of Geophysics and the EGS's Annales Geophysicae, Series B were combined and published jointly by the three societies. The new merged journal retained the name Geophysical Journal for one year, before adopting its current name Geophysical Journal International in 1989. Volume numbering continued from the earlier RAS-only journal. When the EGS merged into the European Geosciences Union in 2002, the new body decided not to continue involvement with GJI, leaving it under the control of the RAS and DGG, which is the current arrangement.

Worked examples

Example 1 — a first encounter with Geophysical Journal International

Start with the simplest possible case. Write down what Geophysical Journal International claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Geophysical Journal International before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Geophysical Journal International ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Geophysical Journal International

In research: Geophysical Journal International appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Geophysical Journal International in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Geophysical Journal International is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic journals established in 1922, English-language journals, Geophysics journals, so understanding it makes those chapters shorter.
In everyday life: Look for Geophysical Journal International outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
