[Montegiove site] Overview of the station site (Montegiove, TR) - June 2023 – First MARGE station installed!

[Alignment of the electrodes 1] The first step to do is to determine North-South and East-West directions and to identify the locations where electrodes will be placed. To accomplish this, we utilize a “surveyor’s cross”, which is a compass equipped with thin slits that allow sighting towards the desired directions. In the picture, team member Massimo Miconi can be seen performing this operation. - June 2023 – First MARGE station installed!
[Alignment of the electrodes 2] The electrodes are positioned at the vertices of a cross, aligned along North-South and East-West magnetic directions with a distance of 40 meters between each electrode and the center.. In the picture, team member Igino Coco can be seen measuring the distance between one of these vertices. - June 2023 – First MARGE station installed!
[Placing the electrodes] The electrodes are cylinders with 10 cm diameter and 15 cm height, containing a copper sulfate solution (CuSO4). They shall be buried in a small hole about 35-40 cm deep, and dipped in a bentonite paste in order to increase the electrode contact resistance. In the picture, the team member Roberta Tozzi is placing an electrode. - June 2023 – First MARGE station installed!
[Connecting the electrodes] Once buried, electrodes are connected to the data recording system through a cable laid on the ground. - June 2023 – First MARGE station installed!
[Solar panels 1] Solar panels play a crucial role in providing a sufficient power source for the station, ensuring its continuous operation over extended periods. - June 2023 – First MARGE station installed!

[Preparatory work for magnetometers accommodation 1] Magnetometers too shall be aligned on the North-South and East-West magnetic directions and buried at a depth of about 50 cm, in order to minimize temperature variations that could influence the measurements and to avoid accidental displacements from the alignment done. The image depicts team member Igino Coco actively engaged in excavating a trench to accommodate a magnetometer instrument. - June 2023 – First MARGE station installed!
[Magnetometers accommodation] A magnetometer accommodated in its trench. The team member Gerardo Romano, by using a spirit level, is verifying that the instrument perfectly lays in the ground plane, without any degree of inclination. - June 2023 – First MARGE station installed!
[Magnetometers coverage] MARGE Project Manager Paola De Michelis makes sure that magnetometers are well covered. - June 2023 – First MARGE station installed!
[Measuring station] The Analogue/Digital Unit (ADU), which allows to connect all the instruments, properly set them up, and acquire long time series of electric and magnetic data. - June 2023 – First MARGE station installed!
