Member States across all European sea basins are encountering similar issues with respect to MSP data needs. These issues stem from the differences in the scope of activities, maritime uses, sea basins and the type of planning that is being carried out in the specific Member States. Common data gaps include socio-economic data for different uses and socio-cultural information. By and large, data and information gaps are less about missing data than about how to aggregate and interpret data in order to acquire the information needed by a planner. Challenges for Member States lie in developing second generation maritime spatial plans, which often require more analytical information and strategic evidence. Underlying this is the need for spatial evaluation tools for assessment, impact and conflict analysis purposes.
Additionally, transnational MSP data needs are different than national MSP data needs. While the scope and level of detail of data needed is typically much simpler at international level, ensuring its coherence and harmonisation across borders remains a challenge. Pan-European initiatives, such as the EMODnet data portal and sea basin checkpoints have the potential to support transboundary MSP data exchange needs by providing access to a range of harmonised data sets across European Sea Basins and testing the availability and adequacy of existing data sets to meet commercial and policy challenges.
The MSP Data Study (2017), conducted by the EU MSP Platform for the European Commission, presents an overview of the data and knowledge needed by Member States to make MSP decisions, taking into account variations in planning scales and the differing points in the MSP cycle. The study examines current and future MSP data and knowledge issues from various perspectives (i.e. from the perspectives of Member States, sea basin(s) as well as projects and other relevant initiatives) in order to identify:
• What data is available for MSP purposes and what data is actually used for MSP;
• Commonalities in MSP projects and Member State experiences;
• The potential for EMODnet sea basin portals to help coordination of MSP at a regional level and options for realising marine spatial data infrastructures to implement MSP;
• Potential revisions to be made concerning INSPIRE specifications for MSP purposes.

What themes or categories of data have been frequently used for the MSP purposes?
MSP information and data needs strongly depend on the type of planning that is being carried out in a particular maritime jurisdiction. However, results based on the MSP Data Study show that the data categories currently used by MSP planners are essentially similar across countries.A general list of types and categories of data and information commonly used in MSP processes have been indicated in Table 1. The table also shows how these MSP data themes and categories relate to INSPIRE spatial themes (column 3). This is not to say that MSP planners have no need for additional data sets, but rather that these may be either unknown or inaccessible to MSP planners, or in fact non-existent due to ‘knowledge gaps’.
Four broad categories have been identified:
1. Administrative boundaries,
2. Description of the geophysical environment and biological/ecological features,
3. Data relating to the relevant human activities and sectors,
4. Socio-economic and policy-related data.
Least variation is noted with respect to the first two categories, i.e. the description of the geophysical environment and biological/ecological features in the planning areas and boundaries (basic geographical and administrative boundaries, such as the limits of the EEZ, country and county boundaries or depth contours).
Physical and biological data are often related to the MSFD categories and, in some cases, are drawn directly from MSFD assessments. Such data is largely descriptive and serves to characterise the planning area and its major features. Where there are direct links to MSFD assessment, the descriptive data categories also include human pressures and occasionally the sources of such pressures (e.g. marine litter, marine underwater noise, point sources of pollution). Linking MSFD and MSP efforts in this manner seems an effective way of ensuring MSP is based on sound environmental evidence; in turn, it is a way of ensuring that MSP is able to contribute to achieving the objectives of the MSFD.
The third category, data relating to human activities and sectors, is more varied. The main sectors are once again similar and differences are mostly found in the weight given to each sector in terms of the diversity of data categories specified and the expression of the sector (e.g. whether offshore energy refers to offshore wind farming, wave energy, CCS, oil and gas, etc.). The most significant differences are found in the fourth category (socio-economic and policy-related data) and whether this is included in the plan/data portal. There is evidence that older plans are less likely to include this type of information (e.g. the German plan for the EEZ) but all of the more recent drafts or plans make some reference to it. It is therefore likely that this data category will become more important in the future.
Data, information, evidence and knowledge are closely related concepts but each has their own role in relation to the other. Knowledge is the logical interpretation of evidence from data and information. Evidence needs are therefore likely to be influenced by:
• The strategic level of the plan, taking its timeframe into account (e.g. requiring evidence on future trends, long-term perspectives, scenarios and projections),
• The level of integration pursued by the plan (e.g. requiring more complex evidence, such as evidence of cumulative impacts of sea use),
• The degree of participation and, linked to this, the types of knowledge included in decision-making (influencing the kind of evidence that is admitted to the decision-making process – e.g. scientific vs. non-scientific evidence),
• The need to be able to justify planning decisions (e.g. if the plan is challenged in court),
• Transboundary dimension of the plan, if relevant,
• Monitoring and evaluation of the planning area and the plan itself.
What are known MSP information gaps?
Most Member States apply a similar approach to stocktaking of current uses and describing the status quo, although they employ slightly different data sets and descriptions of categories in accordance with their needs. However, there is a predominance of descriptive data, which describes the marine environment, and less analytical information, which is where the challenge lies in developing more detailed second generation plans. These tend to be more ambitious in scope and focus on a broader range of evidence. Some data gaps do exist, and commonly, these are found under the categories of socioeconomic data for different uses/activities, commercial fisheries data and socio-cultural information. While the concept of ecosystem services has advanced over the last decade and theoretical approaches have been developed to quantify their value, applying these practically in an ecosystem based approach remains a struggle for planners. Further discussion on socio-economic information can be found in the FAQ on that topic (forthcoming).
Common challenges with respect to data gaps, data policy and transboundary data exchange found at the European, sea basin and regional scales include:
• Availability of suitable data sets in a consistent manner (i.e. compatible formats) across sea basins and regions, coherence across boundaries.
• No statistical unit (i.e. NUTS equivalent) for sea space.
• Difficulty in disaggregating information between land and sea
• Limited availability of data or information on land-sea interactions, e.g. degree to which coastal communities are dependent on their links to adjacent seas and the potential for them to benefit from growing maritime
• Limited access to social, economic and governance data, although this is improving.
• Gaps and weaknesses in historical time series, and ensuring data quality.
Overall, with respect to data and information gaps, the challenge for MSP authorities is not so much about what data but more how to aggregate and interpret the data in order to acquire the information needed by the planner. Further insight into specific data and information gaps are likely to be identified as part of the EMODnet Sea-basin Checkpoints where the availability and adequacy of marine data to meet different commercial and policy challenges is being evaluated.

What data infrastructure have been made/used ?
A systematic analysis of data infrastructures across European sea basins was carried out as part of the Data Study to identify the scope and potential relevance of existing data infrastructures to MSP processes. The focus was on European and national level systems which are operational (i.e. regularly updated and maintained). Themes and sub-themes adopted from the MMO Evidence Strategy 2015 – 2020 were used to establish the scope of the data infrastructure with respect to providing relevant data for MSP purposes. A total of 60 data infrastructures potentially addressing one or more of the above MSP process themes were identified. Among these, a broad coverage of different types of data infrastructures across the different sea basins was found, with data portals being at the forefront, followed by GIS mapping tools and information services. The following table presents the findings from the MSP Data Study on Data Infrastructures:

What are some assessment/decision support tools that have been used for MSP?
In various completed MSP projects, assessment/decision support tools were used to support the interpretation of information and building of evidence for MSP. However, only in some instances were assessment/decision support tools actually developed and/or applied throughout the course of a project.
According to Sprague & Carlson (1), decision support tools or Decision Support Systems (DSS) are defined as interactive computer-based systems designed to help decision makers use data and models to solve unstructured problems. Decision support tools are commonly separated into 4 distinct classes according to their focus as follows:
- Model driven DSS –are often more complex systems using mathematical, statistical or simulation models to generate results.
- Data driven DSS –do not require a computer model rather allow users to use data to provide specific answers to specific questions for example by selecting options within a database in order to generate a result.
- Communications driven DSS –facilitate communication between different stakeholders to assist in providing different outcomes. An example of this could be online collaboration systems.
- Knowledge driven DSS –(also known as expert DSS) use a series of stored rules and facts in order to generate results. These systems are designed to produce results, which mimic the way experts reach decisions.
Below is a list of examples of different decision support tools that are available:
Developed by the University of Queensland Marxan is a model driven decision support tools which is most commonly be used in the selection of site for nature protection. It is reported to be the most widely used decision support software used for conservation planning globally and used in 184 countries globally (Marxan.net). As part of the BaltSeaPlan and BALTSPACE projects, the Marxan software tool was tested in MSP for site selection of i.e. offshore wind power and/or fishery areas. Further resources on how to use Marxan are available from PacMARA.
The DISPLACE project developed a model based platform primarily for research purposes aimed to transform the fishermen’s detailed knowledge into models, evaluation tools. The software also has the facility to incorporate other utilization of the sea including but not limited to energy production, transport and recreational uses.
The DeCyDe for Sustainability tool is a data-driven, spread sheet based set of indicators and decision support tool that allows coastal communities and authorities to self-assess their progress towards sustainability goals.
FisherMap is an example of a communication driven decision support tool, which aimed to map the nature and extent of fishing activities and fishermen’s knowledge of marine ecosystems. The tool developed by Finding Sanctuary a regional development partnership aimed to assist them in developing a network of Marine Protected Areas around the coasts and seas of South West England. A series of interviews were conducted with individual fishermen who also highlighted they areas they used on maps along with providing information of the types of equipment used, species targeted and other relevant information. The results were fed into a GIS database and maps digitised. The information was used to create summary maps, which were made publicly available.
Recent reviews have been conducted regarding the use of decision support tools in MSP, including recommendations for future application (2) (3). Descriptions of additional decision support/assessment tools which are or could be used in an MSP process are available under the tab "Decision Support / Assessment Tools" below, and a list of those that have been used in MSP projects can also be found in Table 3 from the MSP Data Study.

Does a common standard exist for representing uses / sectors / activities on maps used in national MSPs?
Cartographic standards for MSP are a national issue, often determined based on specific national planning ordinances. Therefore, common and agreed standards for representing uses / sectors / activities on maps in national MSP plans do not yet exist across EU Member States. As a result, uses and their respective spatial areas are often symbolised in diverse formats.
However, there have been some attempts at the sea-basin level to develop common cartographic standards for depicting maritime uses and activities as a result of voluntary, transnational cooperations. For example, the Adriatic Atlas to support ICZM and MSP was one the outputs of the Shape project in the Adriatic Sea region.
Additionally, the INSPIRE Directive relates to data on spatial aspects of maritimes uses and activities. The relationship between the INSPIRE Directive and MSP data is discussed in the recently published MSP Data Study, specifically in the section "MSP data themes and the INSPIRE Directive.“
