Clément Adrien Vincendon-Dumoulin made the first calculation of magnetic declination, thus allowing the location of the magnetic South Pole (January 23, 1838), and drew up the 1st map of magnetic declination. Place (Earth is the third planet in the solar system in order of distance…) Adelie (1840)

Riding the Astrolabe by Dumont d’Urville (1837-1840)

In 1837, at the suggestion of Admiral Ferdinand Hamelin, it was named “a. man (A male is an adult male individual of a species called Modern Man (Homo…).) who is wise and industrious will do us good,” he was appointed hydrographer.

This is when it happened navigation (Navigation is a collection of science and capabilities:) More than 3 years (July 1837 – November 1840) Adélie Land (Antarctica) will be discovered (January 1840); he will also be the first Frenchman to see him hoisted on a pole he is not afraid to climb.

Its main mission is to map the poorly known coasts that the two ships of the expedition will pass.

It will solve a specific problem of voyages of discovery: coasting without having and being able to disembark from predetermined points: raise under sail.

His method of hoisting under sail is very clearly explained in volume 1 of the volume devoted to hydrography in the edition of the voyage, and cartography (Cartography refers to the preparation and study of geographic maps. The…) as abundant as accurate; he did not replace the graphic constructions he proposed with other more ingenious constructions, but there was a need to quickly draw the coast from the coast. the sea (The term sea encompasses several realities.)

Dumont d’Urville will be pleased to name five islands near him Land of Louis-Philippe “Dumoulin Islands”, then others Adelie Land (66 deg latitude (Latitude is an angular value, an expression of the north-south position of a point on Earth…) south).
