Abstract—In 2003, measurements of the total ozone content (TOC) in the central Arctic Basin were resumed
after a long-term break at the NP-32 and NP-33 drifting research stations. This paper presents the first results
of analyses of the observational data obtained at the NP-32 and NP-33 stations and aboard the R/V Akademik
Fedorov. An approach allowing comparison of the mean ozone-content values measured in different time peri-
ods from moving platforms, such as drifting stations and research vessels, is used. The TOC variability over the
central Arctic Basin in 2003–2005 is described, and results of comparison of these data with the data of both
long-term TOC measurements at a number of stationary Arctic stations in 1973–2002 and measurements at the
NP-22 station in 1976–1977 are presented.
