A magnetometry survey of the interior of the hillfort in 2010 revealed over 400 circular anomalies of uncertain purpose ( maculae ) distributed across the fort, although there were fewer around the south-east.

As early as the 18th century he was also the first to propose that light from the stars could be deflected by their own gravity, and has been described as the father of seismology and magnetometry.

By analyzing the magnetometry maps in the light of actual excavations of representative areas, the archeologists detected patterns suggesting a planned community that, as Algaze said, " was built in one go ."

With John Gater, Gaffney co-authored the book " Revealing the Buried Past : Geophysics for Archaeologists " and along with Schmidt and Aspinall, Gaffney authored " Magnetometry for Archaeologists ".

A private nonprofit group located the ship Feb . 23 with aerial magnetometry, and divers recovered two artifacts-- a pistol and a musket-- that provided preliminary confirmation that the sunken hulk was La Salle's ship.

Magnetometry can also detect buried metal ( or indeed fired objects such as bricks or even where surface fires were ) using simple total field magnetometers, through to fluxgate gradiometers and high-end alkali vapour gradiometers, depending upon accuracy ( and cost ) required ( see ).

The landscape having been dramatically altered since Dickinson's excavations, in 1982 Stephen Dockrill of the School of Archaeological Science at Bradford University undertook two trial magnetometry and resistivity trial surveys of the site; the latter showed a possible base and ring-ditch surrounding a ploughed-out tumulus.

Specific facilities are a clean room for thin film deposition and nanolithography, Sputtering, Pulsed Laser Deposition and Spin Coating as well as lift-off and RIE facilities for lithography, profilometry, Atomic / Magnetic Force Microscopy, SQUID and Magneto Optical Kerr Effect ( MOKE ) magnetometry, etc.

He has both exploited and advanced methods in experimental low temperature physics, developing new techniques ( hydrostatic pressure, stress, magnetometry, calorimetry ) for high-resolution studies at milliKelvin temperatures, complementing laboratory dilution refrigerator approaches with synchrotron x-ray measurements in diamond anvil cells at cryogenic temperatures.

This is a mid-neolithic barrow dated to the approximate period 3300-2800 BC . Previously known only from a cropmark, magnetometry and resistivity surveys have produced more detailed information about this unexcavated site, which is on level ground on the flood plain of the River Thames at SU 9170 7935, 250 metres from the river.
