The objective of the research is to outline the modern multilingualism and internationalization issues of the educational process through the practical implementation of the new ESP ideas at the Northern (Arctic) Federal University. We pay special attention to the key foreign language competencies and skills development of future professionals. The experimental part of the research included implementation of "The Arctic Quest", designed by Zhanna Elukova for ESP lessons, and developing criteria for foreign language mastering skills assessment necessary for being involved effectively into the multilingual and cross-cultural educational interaction. The methods used are a pedagogical experiment and the analysis of the experiment results. The results of the research show that implementing Arctic content into ESP lessons and after class activities allows stimulating and motivating the students for the autonomous learning, and involving the undergraduates into the multilingualism education process through ESP class activities.
