A full year of measurements of surface ozone over the Arctic Ocean far
removed from land is presented (81° N–88° N latitude). The
data were obtained during the drift of the French schooner TARA between
September 2006 and January 2008, while frozen in the Arctic Ocean. The data
confirm that long periods of virtually total absence of ozone occur in the
spring (mid March to mid June) after Polar sunrise. At other times of the
year, ozone concentrations are comparable to other oceanic observations with
winter mole fractions of ca. 30–40 nmol mol<sup>−1</sup> and summer minima of
ca. 20 nmol mol<sup>−1</sup>. Contrary to earlier observations from ozone sonde data
obtained at Arctic coastal observatories, the ambient temperature was well
above −20°C during most ODEs (ozone depletion episodes). Backwards
trajectory calculations suggest that during these ODEs the air had previously
been in contact with the frozen ocean surface for several days and originated
largely from the Siberian coast where several large open flaw leads and
polynyas developed in the spring of 2007.
