... temporary broadband deployments. The largest of these is IberArray (Díaz et al., 2009) that covered northern Morocco and the Iberian Peninsula in three consecutive deployments, starting in the south in 2007 and ending in the north in 2013, resulting in a total of 167 sites. Subsequently, other tempo ...

Types of Tides - whatsinthebay
... The gravitational force of the moon is one ten-millionth that of earth, but when you combine other forces such as the earth's centrifugal force created by its spin, you get tides. The sun's gravitational force on the earth is only 46 percent that of the moon. Making the moon the single most importan ...

Variations of phase velocity and gradient values of ULF
... A method of constructing of the gradient and phase velocity vectors along the Earth’s surface using three-point measurements of the ULF magnetic field variations was described in (Kopytenko et al., 2000; Ismaguilov et al., 2001; Kopytenko et al., 2002). The phase-gradient method gives a possibility ...

Geodesy
Geodesy (/dʒiːˈɒdɨsi/), — also known as geodetics or geodetics engineering — a branch of applied mathematics and earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space. Geodesists also study geodynamical phenomena such as crustal motion, tides, and polar motion. For this they design global and national control networks, using space and terrestrial techniques while relying on datums and coordinate systems.
