Abstract. Submarine groundwater discharge (SGD) influences ocean chemistry, circulation, and the spreading of nutrients and pollutants; it also shapes sea floor morphology. In the Baltic Sea, SGD was linked to the development of terraces and semicircular depressions mapped in an area of the southern Stockholm archipelago, Sweden, in the 1990s. We mapped additional parts of the Stockholm archipelago, areas in Blekinge, southern Sweden, and southern Finland using high-resolution multibeam sonars and sub-bottom profilers to investigate if the sea floor morphological features discovered in the 1990s are widespread and to further address the hypothesis linking their formation to SGD. Sediment coring and sea floor photography conducted with a remotely operated vehicle (ROV) and divers add additional information to the geophysical mapping results. We find that terraces, with general bathymetric expressions of about 1 m and lateral extents of sometimes >100 m, are widespread in the surveyed areas of the Baltic Sea and are consistently formed in glacial clay. Semicircular depressions, however, are only found in a limited part of a surveyed area east of the island of Askö, southern Stockholm archipelago. While submarine terraces can be produced by several processes, we interpret our results to be in support of the basic hypothesis of terrace formation initially proposed in the 1990s; i.e. groundwater flows through siltier, more permeable layers in glacial clay to discharge at the sea floor, leading to the formation of a sharp terrace when the clay layers above seepage zones are undermined enough to collapse. By linking the terraces to a specific geologic setting, our study further refines the formation hypothesis and thereby forms the foundation for a future assessment of SGD in the Baltic Sea that may use marine geological mapping as a starting point. We propose that SGD through the submarine sea floor terraces is plausible and could be intermittent and linked to periods of higher groundwater levels, implying that to quantify the contribution of freshwater to the Baltic Sea through this potential mechanism, more complex hydrogeological studies are required.

Crisis Of Modernity

Crises in one way or another accompany the development of mankind throughout its history. But the current global crisis is fundamentally different from the previous ones. Its difference is that it is integral, multidimensional, deep and has at its core the oblivion of the spiritual essence of a person. All forms of modern human activity bear the stamp of this oblivion – the spiritual content of any human activity today is minimal and tends to disappear completely. The loss of spirituality, and recently the conscious refusal of a person from his spiritual essence, lies at the basis of the modern global crisis. In turn, the rejection of the spiritual essence by man was the result of the loss of the unity of man and God, which is a moral crime on the part of man. Man has despised the commandments given to him by God, forgetting that the commandments are not only moral maxims, but also the laws of existence, and their fulfillment connects a person with God on an ontological level. Therefore, the current crisis is truly global and eschatological. Overcoming this crisis, getting out of it is possible only on the ways of recreating a person's spiritual essence, on which the future of society and the positive historical perspective of humanity depend.

Mutual Agreement

Meaning formation strategies are one of the integral regulators of modern human activity. To model semantic regulation, two polar strategies of semantic formation are considered: adaptive and developing. The sphere of personal meanings is in mutual agreement with the personality traits manifested in interactions. The article presents the results of empirical identification of polar semantic strategies profiles based on semantic scales of personality traits. We studied a sample (n = 145) with gradations by age, gender, and occupation. Both differences and similarities in the profiles of polar semantic strategies were established. This indicates the dynamics of the world image of the experiencing subject, which reflects the different effects of strategies for the meanings formation.
