The article presents the methodology, statistical analysis and original results of an empirical psychological study of the significant factors of interpersonal interaction of winterers Ukrainian Antarctic Akademik Vernadsky station. The study covers three areas of interpersonal interaction which are strongly interconnected: professional, daily, and leisure. Winterers performed their professional duties and solved daily and leisure problems inside small groups with isolation from the external world. As a result, over four years of observation we have identified the factors and modeled the optimization of interpersonal interaction of peoples in each area. These models can be applied in developing preventive approaches such as psychological training and support the peoples during the log-term expedition.  It will allow to optimize the interpersonal interaction of team members in the extreme conditions of Antarctic winter, increase the effectiveness of their professional activities, reduce the influence of extreme factors of environmental and social environment and creating conditions for optimal social adaptation in a small group.

Introduction. Extreme conditions of Antarctica and socio-spatial isolation of a small group of expeditioners’ significantly affect their physiological and psychological state. Aim. To empirically investigate the changes in the expeditioners’ psychological state indicators during a year-long Antarctic expedition. Methods. For statistical analysis were used Descriptive statistics (mean, standard deviation); One-Sample Kolmogorov-Smirnov Test; and Paired Sample T-Test. Results. The self-assessed indicators of expeditioners’ psychological states rise significantly during the first four months of the year-long expedition. Then their average self-esteem begins to decline gradually, reaching the lowest values in the last two months of stay at the Antarctic station. Conclusions. This study confirms that the long stay and work within an isolated group of people is a factor that affects the expeditioners’ psychological health at the first place.

The extreme working and living conditions at Antarctic stations cause numerous psychological changes in expeditioners. However, research on the changes in expeditioners' personality traits is virtually non-existent. Therefore, the present study aims to determine the changes in expeditioners' personality measures during 1 year Antarctic expeditions. This study examined 56 expeditioners working at the Ukrainian Antarctic Akademik Vernadsky station (52 men, 4 women; ages 20–63 years, M = 38.12, SD = 10.01) who participated in five annual expeditions between 2016 and 2021. The Ukrainian adaptations of four measures were used: the Thomas-Kilmann Conflict Mode Instrument, the Eysenck Personality Questionnaire, the Leonhard-Schmieschek Questionnaire and the Leary Interpersonal Checklist. During 1 year Antarctic expeditions, 8 of the 26 indicators used to describe expeditioners' personality measures changed significantly (P < 0.001–0.1). These indicators belonged to three of the four measures used in the study and were assessed as personally unfavourable. They included increased psychoticism and competing, managerial-autocratic, aggressive-sadistic, responsible-hypernormal, competitive-narcissistic and self-effacing-masochistic styles and a decreased accommodating style. Based on these results, promising areas for further research that could improve psychological selection, training and work for Antarctic expedition personnel are outlined.

Впервые на о. Питерман выявлена ритмическая расслоенность крупнозернистых габброидов поздней интрузивной фазы, которая сходна с дюймовой расслоенностью пород в известном массиве Стиллуотер. Она представлена чередованием темных и светлых полос габброидов, содержащих разное количество пироксена и рудных минералов. В темных полосах размер кристаллов пироксена достигает 4×5 мм, а в светлых-до 1×2 мм. Нами предложена интерпретация образования косой слоистости габброидов м. Туксен в зоне контакта меланократовых и лейкократовых габброидов как следствия кристаллизации минералов при быстром движении магмы. Полученные результаты имеют важное значение для понимания процессов формирования расслоенных базитовых интрузий и оценки перспектив их рудоносности.

Вона представлена чергуванням темних і світлих смуг габроїдів зі вмістом різної кiлькості пiроксену та рудних мiнералiв.
