Observations of the geomagnetic field taken at Earth’s surface and at satellite altitude are combined to construct continuous models of the geomagnetic field and its secular variation from 1957 to 2020.

Jovimagnetic secular variation [PDF]
Planetary dynamos, resulting from fluid flow in electrically conductive parts of their interior, are thought to be highly time dependent. Currently, our understanding of temporal variation of these fields is limited because we only have observations for one example, the Earth.

Community participation in secular and religious contexts across sociodemographic groups in 22 countries [PDF]
In an increasingly fragmented and isolated world, community participation remains an essential source of social connection. However, how community participation varies across countries and sociodemographic groups remains unclear.

Compatibility of magnetic imprinting and secular variation [PDF]
SummaryDiverse ocean migrants, including some sea turtles, elephant seals, and salmon, begin life in particular reproductive areas along coastlines, disperse across vast expanses of sea, and then return as adults to their natal areas to reproduce [1–3].

How might magnetic secular variation impact avian philopatry? [PDF]
A tendency to return to the natal/breeding site, ‘philopatry’, is near ubiquitous amongst migratory birds. It has long been suggested that a magnetic ‘map’ could underpin such movements, though it is unclear how a magnetic map might be impacted by ...

Geomagnetic secular variation [PDF]
Abstract We analyse over 175000 magnetic observations from an interval spanning 1695-1980 to produce a sequence of maps of the magnetic field at the core-mantle boundary; we find that even the earlier data enable us to determine reliable maps.

Dependence of the velocity changes of secular variations on the position of observatory and time
According to the data of world observatories net secular variations of geomagnetic fields from internal and outer sources have been studied. Averaged 3-year data have been used for this purpose.

The Meaning of ‘Secular’ as a Scientific Concept
The meaning of ‘secular’ in the scientific use of ‘secular trend’, ‘secular variation’, and similar terms is a topic that merits historical investigation.

This paper develops a composite absolute paleointensity record for Holocene paleomagnetic secular variation (PSV) from central North America. Twelve full‐vector (inclination, declination, paleointensity) PSV records were assessed in order to build the ...
