Abstract

An investigation of the latitudinal distribution of concentrationsof 137Cs at 19 stations in the surface water of the SouthernOcean on cross-sections to the South from the Cape of Good Hope(section SR2) and in the Drake Passage (30th cruise "Academic Ioffe",01.12.2009–09.01.2010) was performed. The data obtained reinforcedthe time-dependent exponential decrease in the 137Csconcentrations in the surface water of the Atlantic sector of theSouthern Ocean. Increased 137Cs concentrations were foundin the Drake Passage and in the section SR2 in the vicinity of thePolar Front. The average value of 137Cs concentrationsfor all measurements equals 0.18 Bq.m–3 σ = 0.11.
