Communicating uncertainty in geomagnetic field estimates provided by the BGS to aid directional drilling [PDF]
, 2008 Navigating underground when drilling for oil and gas has become more challenging as companies try to hit smaller targets in reservoirs already congested with existing wells.

Archaeological Prospection, EarlyView.ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

Recovering external contribution from the monthly mean series of a given geomagnetic observatory
Annals of Geophysics, 2016 The differences between monthly mean values of the observed geomagnetic field and monthly values predicted by different models of the internal geomagnetic field (named “model biases”) for the time period 2000-2015 at several geomagnetic observatories are

Archaeological Prospection, EarlyView.ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Archaeological Prospection, EarlyView.ABSTRACT Preliminary geophysical investigations are a cost‐effective and efficient way to screen archaeological sites and locate buried structures. Ground‐penetrating radar (GPR) is one of the most widely used methods for archaeological prospection, but in some sites, it cannot be employed effectively due to the presence of clay or other electrically ...

Fifty-year investigation of the correlation between the geomagnetic field and climate
地球与行星物理论评After 50 years of research on the correlation between the geomagnetic field and climate, we have gained a deeper understanding that the regulation of climate by geomagnetic field changes is far more complex than previously imagined.

Revised time-of-flight calculations for high-latitude geomagnetic pulsations using a realistic magnetospheric magnetic field model [PDF]
, 2005 We present a simple time-of-flight analysis of Alfvén pulsations standing on closed terrestrial magnetic field lines. The technique employed in this study in order to calculate the characteristic period of such oscillations builds upon earlier time-of ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.The standalone non‐local thermodynamic equilibrium (NLTE) bias correction schemes, utilizing a look‐up‐table and a linear regression method developed in Part I and new quality control procedures for short‐wave infrared radiances (SWIR), were tested within a data assimilation framework.
