Magnetic declination By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west. Isogonic lines are lines on the Earth's surface along which the declination has the same constant value, and lines along which the declination is zero are called agonic lines.agnetic declination should not be confused with magnetic inclination, also known as magnetic dip, which is the angle that the Earth's magnetic field lines make with the downward side of the horizontal plane.

Magnetic declination Declination is defined as the angle between magnetic north and the true north. However, the diagram on the topographic map sheet gives the value of the angle between magnetic north and grid north, which is referenced to the grid lines shown on the map. This angle is properly called grid declination.erminology. Both declination and variation are used to describe the angle between magnetic north and true north. The term deviation is also used from time to time. Here is an explanation of the differences between the three terms.

How to adjust a compass for magnetic declination or variation The direction in which the compass needle points is known as Magnetic North, and the angle between Magnetic North and the True North direction is called magnetic declination.

decibel Noun. (plural decibels). 1  A common measure of sound intensity that is one tenth of a bel on the logarithmic intensity scale. 2  It is defined as dB = 10 * log 10 (P 1 /P 2), where P 1 and P 2 are the relative powers of the sound.oun.

refraction 2. The apparent change in position of a celestial body caused by the bending of light as it enters the Earth's atmosphere. Usage The words refraction and reflection describe two different ways that a light wave, sound wave, or other wave can move when it encounters a boundary between two media.

Coordinate Systems Instead of latitude, the North-South celestial coordinate is called Declination (Dec). As on the Earth, North-South positions are measured from the celestial equator, with the vertex at the Earth's center. Like latitude, it is measured in degrees, with negative values for positions South of the celestial equator.

Glossary Diurnal inequality. The difference in height of the two high waters, or of the two low waters of each tidal day. Also, the difference in speed between the two flood tidal currents, or the two ebb currents of each tidal day. Diurnal inequality is sometimes called declinational inequality.

Magnetic declination The term magnetic deviation is sometimes used loosely to mean the same as magnetic declination, but more correctly it refers to the error in a compass reading induced by nearby metallic objects, such as on board a ship or aircraft.agnetic declination should not be confused with magnetic inclination, also known as magnetic dip, which is the angle that the Earth's magnetic field lines make with the downward side of the horizontal plane.

Magnetic declination The term magnetic deviation is sometimes used loosely to mean the same as magnetic declination, but more correctly it refers to the error in a compass reading induced by nearby metallic objects, such as on board a ship or aircraft.he magnetic declination in a given area may (most likely will) change slowly over time, possibly as little as 2–2.5 degrees every hundred years or so, depending upon how far from the magnetic poles it is. For a location closer to the pole like Ivujivik, the declination may change by 1 degree every three years.

Decibels General. The decibel, or dB, is a means of expressing the gain of an active device (such as an amplifier) or the loss in a passive device (such as an attenuator or length of cable). It is simply the ratio of output to input expressed in logarithmic form.The decibel was developed by the telephone company to express the gain or loss in telephone transmission systems, and is best understood by first discussing the rationale for its development.he decibel, or dB, is a means of expressing the gain of an active device (such as an amplifier) or the loss in a passive device (such as an attenuator or length of cable).

Compass Depending on where the compass is located on the surface of the Earth the angle between true north and magnetic north, called magnetic declination can vary widely with geographic location. The local magnetic declination is given on most maps, to allow the map to be oriented with a compass parallel to true north.
