“…Using long-term data on salinity, it was possible to calculate the average inflow to approximately 325 m 3 s -1 . This order of magnitude is close to what Engqvist and Andrejev (2003) found using a fine resolution hydrodynamical model to calculate the water exchange in Stockholm archipelago for the year 1992. The average inflow in that year was calculated to be around 390 m 3 s -1 (Engqvist and Andrejev 2003).…”

“…The inflow of water from the outer archipelago goes mainly (around 85%) through the sound Oxdjupet (Fig. 1), but also through the sounds, Kodjupet, Stegesund, Skävsjö-holmssundet, and Baggen-Stäket (Engqvist and Andrejev 2003). The total inflow of water from outside areas to the inner archipelago was calculated through simple mass balance calculations for salt, applying Knudsen's relations (Knudsen 1900).…”

Improved benthic conditions compared to the 1990s were found during benthic investigations, including sediment and benthic macrofauna in the inner Stockholm archipelago during 2008. In the 1990s, these areas were dominated by black and laminated surface sediments and very sparse fauna. A clear relationship was found when comparing sediment status with the benthic macrofauna. Reduced surface sediment and impoverished macroinvertebrate community was only found at one sampling station representing an enclosed part of the inner archipelago, whereas the other seven stations, with depths ranging from 20 to 50 m, had oxidized surface sediments and considerable biomasses of benthic macrofauna (6-65 g m -2 ) dominated by the invading polychaete Marenzelleria neglecta. An extrapolation of the results shows that, within the investigated area, the coverage of reduced surface sediments had decreased from approximately 17% in the late 1990s to 4% in 2008.

“…The transport processes are both advective and diffusive driven by the interacting flows of the northern basins of the Baltic Sea and the North Sea [58]. Particles from Arkona Basin flow northwards along the Stolpe Channel, which is in agreement with Meier et al [6].…”

“…To consider the transport of Cu through the system of recipients, we propose to follow the approach of Engqvist and Andrejev [15] and divide the surface water into connected basins and straits based on geometric form, with straits being narrow, with an associated, expected lower water residence time ( Figure 3). In order to trace the Cu through the system, the water flow through the straits between the basins must be established.…”

“…For the archipelago, Engqvist and Andrejev [15] already suggested a partitioning into basins and straits; for Lake Mälaren and the transitional region, we consider the water bodies with slender form as straits, whereas others were considered as basins ( Figure 6). Basins with a maximum depth of more than 10m were considered deep (full contour ellipse in Figure 6), whereas the rest were considered shallow (dashed contour ellipse in Figure 6).…”

Sources and fates of heavy metals in complex, urban aquatic systems: modelling study based on Stockholm, Sweden

Despite management of point sources, heavy metals today remain at an elevated level in the urban environment, with diffuse sources dominating the emissions. In order to manage these pollutants, it is necessary to understand the coupling between the urban sources of heavy metals and their monitored, environmental levels, for example in aquatic sediments. In this work, we suggest a simple approach to quantitatively model Cu from its urban sources through a complex aquatic system. We apply the proposed model to Stockholm, situated between Lake Mälaren and the archipelago of the Baltic sea, and discuss data availability along with conceptual difficulties. Using literature data, we show that Cu occurs at elevated levels in the aquatic sediment close to the centre of Stockholm, Sweden.
