In industrial prospecting activity that uses the telluric current method, electrodes are properly located on the ground to sense the voltage difference between locations caused by the oscillatory telluric currents. [7] [8] It is recognized that a low frequency window (LFW) exists when telluric currents pass through the Earth's substrata.
Prospecting is the first stage of the geological analysis (followed by exploration) of a territory. It is the search for minerals , fossils , precious metals, or mineral specimens. It is also known as fossicking .

In the early 1890s, Joplin's friends, the brothers Tom and Charles Turpin, had done prospecting in the Searchlight, Nevada area. The brothers' frequent stories of this experience, recounted to the patrons of their bar, inspired the title of the rag.
The Baltic Sea anomaly is a feature visible on an indistinct sonar image taken by Peter Lindberg, Dennis Åberg and their Swedish OceanX diving team while treasure hunting on the floor of the northern Baltic Sea at the center of the Gulf of Bothnia in June 2011.
In anomaly detection, the local outlier factor (LOF) is an algorithm proposed by Markus M. Breunig, Hans-Peter Kriegel, Raymond T. Ng and Jörg Sander in 2000 for finding anomalous data points by measuring the local deviation of a given data point with respect to its neighbours.
Prospecting took place under the auspices of NUNAOIL, a partnership between the Greenland Home Rule Government and the Danish state. Various oil companies secured licences and conducted exploration over the period 2002 to 2020.
