In 2006, Barrick Gold had proposed moving the glacier ice from the Toro 1, Toro 2 and the Esperanza glaciers to facilitate their exploitation of the region’s resources.
The case is County of Los Angeles et al v Monsanto Co et al, U.S. District Court, Central District of California, No. 19-04694.
The World Magnetic Model (WMM) is a standard model of the core and large-scale crustal magnetic field. It is used extensively for navigation and in attitude and heading referencing systems by the UK Ministry of Defence, the US Department of Defense, the North Atlantic Treaty Organization and the International Hydrographic Organization.
The WMM is a model of the core and large-scale crustal fields only. However the satellite data contain unwanted signals such as small-scale crustal, external ionospheric and magnetospheric and their induced counterparts. These fields would have added noise to the WMM2015 SV model and could have biased its estimates.
BGS employed two techniques to avoid the contamination caused by external magnetic fields. Firstly we rejected those data most contaminated by these sources, as identified by a combination of local time, geomagnetic indices and solar wind data. ……..
