摘要

研究了大西洋50°S ~ 61°N区域保守放射性污染物137Cs的纬向分布。由于阿古拉斯泄漏而向南大西洋供应的这种放射性核素在南纬31°S提供了与北大西洋相当的高活度浓度，为- 1.32 Bq/m3，尽管受到南极水域的稀释影响，但在南纬40°S - 50°S的活度浓度几乎不变（~ 0.60 Bq/m3）。中大西洋（30°S - 15°N） 137Cs的平均活度浓度也高于往年，达到1.00 Bq/m3。1989-2022年北大西洋（15°N - 45°N）未发现显著的137Cs输入源；到2022年，其平均活性浓度降至1.21 Bq/m3。

Distribution of 137Cs in surface waters of the Atlantic Ocean (50°S – 61°N) in 2020–2022 based on field research on cruises 79 and 87 of the R/V “Akademik Mstislav Keldysh”

The cross-latitudinal distribution of conservative radioactive pollutant ¹³⁷Cs in the Atlantic Ocean from 50°S to 61°N was studied. Supply of this radionuclide into the South Atlantic due to the Agulhas Leakage provides high activity concentration levels at 31°S, comparable to those in the North Atlantic, − 1.32 Bq/m³, and almost constant activity concentration (~ 0.60 Bq/m³) at latitudes of 40°S - 50°S, despite the diluting influence of Antarctic waters. In the Central Atlantic (30°S – 15°N) average activity concentration of ¹³⁷Cs was also higher than in previous years and amounted to 1.00 Bq/m³. No significant sources of ¹³⁷Cs input were found in the North Atlantic (15°N – 45°N) in 1989–2022; its average activity concentration decreased by 2022 to 1.21 Bq/m³.

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
