“…Furthermore, we included all depth levels given in Table 1, although the cultivation at different water depths will require different technologies, some of them more feasible than others. Information about offshore installations, alterations required or other further details might be provided by [62,53,13,19]. The potential of a site for co-location depends on biological, ecological and hydrological factors.…”

“…The possibility of co-location depends on site specific characteristics and adaptive management [3,12]. In this field, case studies are essential to explore co-location-options, like [13] for offshore aquaculture in combination with wind farms in Danish waters or by [11] as well as [14] for co-management options and legal constraints for offshore aquaculture possibilities in German waters. According to [15], not only the research community but also the policy makers are interested in 'sustainable, resource-and spaceefficient solutions'.…”

“…Selecting offshore areas for IMTA brings advantages such as enhanced water quality due to higher levels of dissolved oxygen, less impact by other human activities and opportunities to increase the scale and expansion for aquaculture [11,13,19,21,22]. In spite of the risks (currents, strong wave action, harsh offshore wind conditions) and disadvantages (increasing environmental costs in comparison to onshore aquaculture due to logistics) [19], offshore aquacultures have already been successfully undertaken for haddock, halibut and mussels in the US waters [23] as well as oysters and mussels within the German Bight [24].…”

“…There can be positive effects concerning shared logistics and infrastructure and restrictions for other types of activities due to the security zone around the OWFs. Further, next to 'room-in-room-solutions' the provision of OWFs structures to build on has been discussed [11,13,25,26], though, according to [27,13], this purpose would require alterations to OWF technologies. As this not only leads to increased costs, but also to extraordinary forces acting upon aquaculture cages and potentially destroying OWF structures, latest plans do refrain from banking on such doubled benefits.…”

A GIS modelling framework to evaluate marine spatial planning scenarios: Co-location of offshore wind farms and aquaculture in the German EEZ

a b s t r a c tThe concept of co-location of marine areas receives an increased significance in the light of sustainable development in the already heavily used offshore marine realm. Within this study, different spatial colocation scenarios for the coupling of offshore aquacultures and wind farms are evaluated in order to support efficient and sustainable marine spatial management strategies. A Geographic Information System (GIS) and multi-criteria evaluation (MCE) techniques were combined to index suitable co-sites in the German exclusive economic zone of the North Sea. The MCE was based on criteria such as temperature, salinity or oxygen. In total, 13 possible aquaculture candidates (seaweed, bivalves, fish and crustaceans) were selected for the scenario configuration. The GIS modelling framework proved to be powerful in defining potential co-location sites. The aquaculture candidate oarweed (Laminaria digitata) revealed the highest suitability scores at 10-20 m depth from April to June, followed by haddock (Melanogrammus aeglefinus) at 20-30 m depth and dulse (Palmaria palmata) and Sea belt (Saccharina latissima) at 0-10 m depth between April and June. In summary, results showed several wind farms were de facto suitable sites for aquaculture since they exhibited high suitability scores for Integrated MultiTrophic Aquaculture (IMTA) systems combining fish species, bivalves and seaweeds. The present results illustrate how synergies may be realised between competing needs of both offshore wind energy and offshore IMTA in the German EEZ of the North Sea. This might offer guidance to stakeholders and assist decision-makers in determining the most suitable sites for pilot projects using IMTA techniques.

“…Social scientific research analyzed social acceptance by wind-park operators, fishermen, and the like [13,14]. Economists have addressed the question of economic feasibility [15,16], while others have focused on planning issues [17] and identification of the proper sites for MUPS [18]. These multi-use platforms are difficult to realize as they come with a set of complex knowledge questions, challenges for governance, and issues of sustainability, and require cross-sectoral cooperation [13][14][15].…”

Participatory Design of Multi-Use Platforms at Sea

et al. 2016

European oceans are subject to rapid development. New activities such as aquaculture and ocean energy have gained importance. This triggers interest in "multi-use platforms at sea" (MUPS), i.e., areas at sea in which different activities are combined. MUPS are complex features with regards to technology, governance, and financial, socioeconomic, and environmental aspects. To identify realistic and sustainable solutions and designs for MUPS, the MERMAID project applied a participatory design process (PDP) involving a range of stakeholders representing companies, authorities, researchers, and NGOs. This paper evaluates if and how the participatory design process contributed to the design of multi-use platforms. It is based on interviews with the managers of the case study sites and a questionnaire administered to all stakeholders participating in the PDP workshops. Analyzing the four case studies, we conclude that the participatory design process has had a valuable contribution to the development of the four different designs of MUPS, even though the preconditions for carrying out a participatory design process differed between sites. In all four cases, the process has been beneficial in generating new and shared knowledge. It brought new design issues to the table and increased knowledge and understanding among the different stakeholders.

Marine Spatial Planning (MSP) requires the analysis of the spatial distribution of marine uses and environmental conditions. Such analyses can be carried out with GIS, but standard GIS programs do not feature a toolbox that combines the most needed functionalities for such analyses. The SPACEA toolbox presented here was created to bundle and adapt existing functionalities in one toolbox. SPACEA consists of several script tools that have been designed to be user-friendly and applicable to different analyses for MSP. This includes the processing of different input layers with regard to marine uses and environmental conditions. The main functionalities of SPACEA are exemplified in a fictional case study in the Baltic Sea, where the tools are applied to find potentially suitable areas for mussel farming. The tools feature a user-friendly interface and more experienced users may also use the provided sample codes to run it from the python window or as a stand-alone script. As such, the tools can be applied by users with different levels of GIS knowledge and experience.
