The geochemical equilibrium in the seawater must be observed taking into account the chemical, geological as well as biological processes. Namely, the concept of equilibrium takes into account the composition of the system and the kinetics of the reactions taking place therein. In coastal waters, nutrients and trace elements can be delivered not only through rivers but also through atmospheric input and submarine groundwater discharges. In addition to natural sources, levels of different elements can also be influenced by growing and diverse human activities along the coasts. Consequently, the pathways and fate of different environmental chemicals in coastal areas are governed by various factors. The multiparameter approach, combined with different statistical tools, is a well-established way of interpreting their inputs and behaviour in marine systems. Nevertheless, the data for the karst regions, as found in the Mediterranean, are particularly scarce. The Special Issue “Geochemical Equilibrium and Processes in Seawater” of Geosciences gathers five articles on different topics related to water and sediment geochemistry of the coastal karst areas of the Mediterranean, including Slovenia, Croatia and Egypt. The topics included by this Issue refer to 1) geochemistry of sediments in the area of intensive anthropogenic activity, 2) the geochemistry of sediment and biota in protected area under increasing pressure due to tourist activity, 3) the influence of thermal power plant on the geochemistry of the surrounding area, 4) the influence of underground water discharges on the water quality, and 5) the possibility of monitoring natural and anthropogenic processes in karst systems by using a specific group of elements.
