Total ozone content (TOC) measurements have been performed by different organizations on a regular basis at Murmansk (φ = 68.97°N, λ = 33.05°E; Ф=64.5°N,  115.2°E). All the data of ozone observations since the beginning of observations in 1971 till 1997 are collected as a data base in the Geophysical Observatory Loparskaya. An initial analysis of collected data was implemented and it was noted that the TOC over Murmansk during the last 27 years showed the decreasing of the one. A seasonal behaviour and other characteristics of TOC were obtained.
