No evidence for the use of magnetic declination for migratory navigation in two songbird species. [PDF]
Determining the East-West position was a classical problem in human sea navigation until accurate clocks were manufactured and sailors were able to measure the difference between local time and a fixed reference to determine longitude.

Research on WMM-00 geomagnetic field model accuracy in Lithuanian territory
The development of surveying technology gives the possibility for a detailed exploration of physical processes on the Earth’s surface. The satellite geomagnetic surveys, the precise geomagnetic surveys in magnetic observatories, the measurement at repeat

Changes in the level of magnetic declination in the Adriatic from 1806 to 1995 – a contribution to the history of Adriatic seafaring [PDF]
The paper analyzes changes in magnetic declination in the Adriatic Sea from the first measurements in 1806 to the latest isogonic charts from 1995. The basis of analysis are data provided by the Adriatic pilot books as literature that mariners used as an

Measurement experiences with FluxSet digital D/I station [PDF]
Geomagnetic observatories use classical theodolites equipped with single-axis flux-gate magnetometers known as declination–inclination magnetometers (DIM) to determine absolute values of declination and inclination angles.

Research on magnetic declination in Lithuanian territory
Magnetic declination is the angle between the planes of the astronomic and magnetic meridians. Magnetic declination is used in navigation, geophysics, geodesy, cartography, geology, and other fields.

Effects of neutral wind on the electron temperature at a height of 600 km in the low latitude region [PDF]
Electron temperature observed by the Hinotori satellite with the low inclination at the height of ~600 km was studied in terms of local time, season, latitude, magnetic declination and solar flux intensity during a 16-month period from 1981 to 1982 ...

Magnetic declination of the territory of Ukraine: the results of observations and calculations
A technology is proposed for calculating the strength and angular components of the vector of the induction of the Earth's magnetic field. The technology is based on the development of a three-dimensional model of the earth's crust and the calculation of
