波罗的海深水的通风是由大风强迫的正压或斜压盐水流入驱动的。近二十年来，大正压流入（主要在冬季）的频率有所减少，中等强度斜压流入（在夏季）的频率有所增加。由于周围富氧水的夹带，夏季流入对深水通风也很重要。最近对盐水羽流的过程研究表明，夹带速率通常比早期夹带模型预测的速率要小。除了入口区域，Slupsk井和Slupsk沟也是水团转化的重要地点。通过斯卢普斯克沟，重力驱动的密集底流和地下气旋涡旋都被温盐侵入侵蚀，使哥特兰盆地东部的深水通风。最近一项利用二维浅水模型对正压波运动向斜压波运动的能量转移进行的研究表明，在盐斜层以下深水混合所需的能量中，约有30%是由内波的破裂来解释的。在深水区，氧浓度下降和硫化氢浓度增加的十年停滞期可能是由异常大的淡水流入和异常高的平均纬向风速引起的。在不同的研究中，估计平均盐度的典型反应时间尺度大约在20至30年之间。这篇综述总结了最近的研究成果，最后列出了一系列悬而未决的问题和建议。
The ventilation of the Baltic Sea deep water is driven by either gale-forced barotropic or baroclinic salt water inflows. During the past two decades, the frequency of large barotropic inflows (mainly in winter) has decreased and the frequency of medium-intensity baroclinic inflows (observed in summer) has increased. As a result of entrainment of ambient oxygen-rich water, summer inflows are also important for the deep water ventilation. Recent process studies of salt water plumes suggest that the entrainment rates are generally smaller than those predicted by earlier entrainment models. In addition to the entrance area, the Slupsk Sill and the Slupsk Furrow are important locations for the transformation of water masses. Passing the Slupsk Furrow, both gravity-driven dense bottom flows and sub-surface cyclonic eddies, which are eroded laterally by thermohaline intrusions, ventilate the deep water of the eastern Gotland Basin. A recent study of the energy transfer from barotropic to baroclinic wave motion using a two-dimensional shallow water model suggests that about 30% of the energy needed below the halocline for deep water mixing is explained by the breaking of internal waves. In the deep water decade-long stagnation periods with decreasing oxygen and increasing hydrogen sulphide concentrations might be caused by anomalously large freshwater inflows and anomalously high mean zonal wind speeds. In different studies the typical response time scale of average salinity was estimated to be between approximately 20 and 30 years. The review summarizes recent research results and ends with a list of open questions and recommendations.
