No evidence for the use of magnetic declination for migratory navigation in two songbird species. [PDF]

open access: goldPLoS ONE, 2020
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 magnetic declination in Lithuanian territory

open access: diamondAviation, 2008
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.

Changes in the level of magnetic declination in the Adriatic from 1806 to 1995 – a contribution to the history of Adriatic seafaring [PDF]

open access: yesGeodetski Glasnik, 2017
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

Halley's Chart of Magnetic Declinations [PDF]

open access: bronzeNature, 1896
WITHIN the last few days I have come into possession of another early map showing Halley's lines. The date of this map is 1725, and it was published by John Senex, F.R.S. It is entitled “A Map of the World, corrected from the Observations communicated to the Royal Societys of London and Paris.” The map consists of the two hemispheres, each of which is ...
