During the last years of Emperor Trajan’s reign, the Legio IV Scythica was stationed in the capital of Armenia at that time, Artaxata. It had made its way there within the scope of the Roman campaign against the Parthians. Its presence was immortalised on stamped rooftiles, bricks and a monumental inscription discovered by the southern border of the present-day village of Pokr Vedi. The inscription carved into limestone confirms the building activities of the Roman army. Similar inscriptions were frequently placed on the gates and most important buildings in legionary camps. Polish and Armenian archaeologists undertook a joint search for the supposed camp of the Fourth Scythian Legion in the vicinity of the present-day village of Pokr Vedi, where the above-mentioned construction inscription had been found. The field surveys conducted within the framework of the Pokr Vedi Project were mainly of a non-invasive character. The following were applied: surface prospection, aerial photography, interviews with the inhabitants, scanning of part of the terrain and geophysical measurements done using two methods: electrical resistivity and magnetic measurements. The accumulated data enabled the selection of sites in which survey trenches were located

Geophysical Measurements

The purpose of this study was to use fast geophysical measurements of soil magnetic susceptibility (κ) as supplementary data for chemical measurements of selected light rare earth elements (REEs) in soil. In order to ensure diversity in soil conditions, anthropogenic conditions and types of land use, seven areas were selected, all located in regions subjected to past or present industrial pollution. Magnetometric parameters were measured using a selected magnetic sensor that was specially designed for measurements of soil cores and were used to classify collected soil cores into six distinctive types. The analysis of REEs concentrations in soil was carried out taking into account the grouping of collected soil samples based on the type of study area (open, forested and mountain), and additionally on the measured magnetometric parameters of collected soil cores. A use of magnetometric measurements provided different, but complementary to chemical measurements information, which allowed to obtain deeper insight on REEs concentrations in soils in studied areas.

Geophysical Measurements

When geophysical measurements are made from the air, it is important to know the position of the aircraft. The position at any time is usually known from a combination of position-fixing and dead-reckoning systems. In-flight optimization of this combination is a well-studied subject. When post-flight track plotting is required for geophysical survey, use can be made of both the initial and terminal position fixes to correct the dead-reckoning track and hence improve on the in-flight version. This technique is applied to compute the track of aircraft conducting ice thickness measurements in the Antarctic, and the effect of certain errors is evaluated. The algebraic results are equally applicable in parts of the world where better navigational aids are available. A relation is derived between the track plotting errors and die errors in the geophysical measurement such that the precision of one is not degraded by errors in the other.
