Based on the vertical distribution of ²¹⁰Pb activity concentrations in bottom sediment, linear accumulation rates (LAR) and mass accumulation rates (MAR) were determined for 31 locations in the southern Baltic Sea region by applying models: Constant Flux Constant Sedimentation Rate (CF:CS) and Constant Rate of Supply (CRS). The dating of sediment layers in selected locations was also carried out. The reliability of the results was verified using radiotracers: ¹³⁷Cs and, for the first time, ⁹⁰Sr. The results obtained were the basis for the development of maps of continuous distributions of LAR and MAR values in the areas where a particular type of bottom sediments were found: silt-clay, sandy silt, silty sand and mixtites covering the region of the southern Baltic. The maps constitute a tool supporting basic and applied research. Data for marine open areas were supplemented with sediment accumulation rate data for the areas of the Szczecin Lagoon and the Vistula Lagoon. The linear accumulation rates of bottom sediments of the southern Baltic varied from 0.61 to 3.54 mm y⁻¹ while mass accumulation rates ranged from 390 g m⁻² y⁻¹ to 910 g m⁻² y⁻¹, largely reflecting the LAR values.

根据底部沉积物中²¹⁰ Pb活度浓度的垂直分布，通过应用以下模型确定波罗的海南部地区31个地点的线性累积率（LAR）和质量累积率（MAR）：恒定通量恒定沉降率（CF： CS）和恒定供应率（CRS）。还对选定位置的沉积物层进行了测年。使用放射性示踪剂验证了结果的可靠性：¹³⁷ Cs，首次为⁹⁰Sr.所获得的结果是在发现特定类型底部沉积物的地区开发LAR和MAR值的连续分布图的基础，这些沉积物包括：粉砂粘土，砂质粉砂，粉质砂和覆盖该地区的混合岩。波罗的海南部。这些地图构成了支持基础研究和应用研究的工具。海洋开放区域的数据补充有什切青泻湖和维斯杜拉泻湖区域的沉积物累积速率数据。波罗的海南部南部底部沉积物的线性累积速率从0.61到3.54 mm y ^-1变化，而质量累积速率从390 g m ^-2 y ^-1到910 g m ^-2 y ^-1不等，在很大程度上反映了LAR值。
