\begin{abstract}
This study assessed total hydrocarbon content and polycyclic aromatic
hydrocarbon content in Gr\selectlanguage{ngerman}önfjord (the Greenland Sea, Svalbard). The
field study was held in marine expeditions of research vessel
``Barentsburg'' by the North-Western Branch of the Federal State Budget
Institution, Research and Production Associaton «Typhoon» in summer
periods of 2012 to 2022. In the framework of the field works
simultaneous measurements of hydrological and hydrochemical
characteristics of the water column were done. The data was analyzed
using standard procedure in purpose to gather new information about the
levels of hydrocarbons~ ~ (measured as total hydrocarbon contents),
polycyclic aromatic hydrocarbons. The results showed pronounced
interannual variations of total hydrocarbon contents and polycyclic
aromatic hydrocarbons concentrations. Supposed that local natural
sources contribute to elevated polycyclic aromatic hydrocarbons and
total hydrocarbon content levels both in water and in sediments,~ the
levels of contamination do not signify exclusively anthropogenic
influence on the sea-body. At the same time, some local elevated
petroleum hydrocarbons concentrations, which were detected in the
surface water layer, may be a sign of existing industrial activity
affecting the waters of the fjord. Continuity of tasks starting from
earlier expeditions indicates that many processes in
the~Norwegian~Sea,~Greenland~Sea require further research.%
