		In 1730 he was made professor of hydrography at Havre, and succeeded Pierre Louis Maupertuis as associate geometer of the Academy of Sciences.

		Bouguer was a prodigy trained by his father, Jean Bouguer, in hydrography and mathematics.
		Bouguer measured gravity by pendulum at different altitudes and was the first to attempt to measure the horizontal gravitational pull of mountains.
		He observed the deviation of the force of gravity, measured on a high plateau, from that calculated on the basis of the elevation, and he correctly ascribed the effect to the mass of matter between his station and mean sea level.

		The Bouguer (named after Pierre Bouguer, a French geodesist) gravity field is often noted as simple Bouguer for the gravity field before applying terrain corrections or complete Bouguer for the gravity field after applying terrain (and sometimes curvature) corrections.
		The gravity anomalies observed in the Bouguer field are caused by lateral density contrasts within the sedimentary section, crust and sub-crust of the earth.
		The Bouguer correction requires an estimation of bulk density to calculate and eliminate the gravitational effect of the subsurface mass between point of gravity measurement and a datum.

	Antonio de Ulloa - Wikipedia, the free encyclopedia
		In 1735 he was appointed with fellow Spaniard Jorge Juan a member of a scientific expedition which the French Academy of Sciences was sending to Peru to measure a degree of the meridian at the equator, led by Pierre Bouguer.
		His name is also recalled as the meterological term Ulloa's halo (also known as Bouguer's halo) which an observer may see infrequently in fog when sun breaks through (for example, on a mountain) and looks down-sun -- effectively a "fog-bow" (as opposed to a "rain-bow").
		A fog-bow is defined as "an infrequently observed meteorological phenomenon; a faint white, circular arc or complete ring of light that has a radius of 39 degrees and is centered on the antisolar point.

	Calculating Bouguer Anomalies from Observed Gravity Values (Site not responding. Last check: 2007-10-09)
		The process involved calibrating the data, applying tidal corrections, averaging repeated values and their times of occupation, dedrifting the values, obtaining gravity differences between the base and the stations referred to it, and finally converting the relative values to absolute values using a base at which absolute gravity is known.
		The Bouguer anomaly is named after a French scientist (Pierre Bouguer), who derived the formula for an infinitely extending slab, the basis for the so-called mass correction (discussed below).
		Two types of Bouguer anomalies are recognized: (1) simple Bouguer anomalies, in which the various factors have been corrected, with the exception of terrain effects, and (2) complete Bouguer anomalies, for which terrain effects have also been removed.
