Fig. 1. Fieldwork.
In July and August 2019, the Federal State Budget Institution «Russian Arctic National Park» organized an expedition to the islands of the Franz Josef Land to study oil-contaminated areas.
The ground-penetrating radar method is well known for localization of oil polluted areas, so the organizers turned to us for cooperation and assistance with GPR equipment.
GPR profiling was performed using the GROT-10 georadar, which is the prototype of modern serial GROT 12 georadars.

Fig. 3. Photo from the fieldwork site. Rainbow film is visible, which is typical for areas contaminated with oil products.
The purpose of georadar profiling was to localize underground zones of contaminated soil.
Fig. 4. Radargram considering the topography and figured out zones of interstratal filtration.
On the radargram (fig. 4) zones of interstratal filtration are visible (marked with black ovals). In these zones, seepage occurs and pollutants penetrate into the underlying layers.
Specialists are aware of cases when, while drilling in these lands, they came across kerosene lenses at a depth of 6 meters. GPR studies help localize similar anomalies.
We express our gratitude to Dmitry Kryukov and all the Russian Arctic National Park for cooperation!
