Poster para Congreso The Maritime Spatial Planning (MSP) INSPIRE data model concept has been developing from 2014, applying Infrastructure for spatial information in Europe Directive 2007/2/EC (INSPIRE) data management concepts for marine planning, through the Marine Pilot project (EC Joint Research Centre 2014-2016) and continuing with the PLASMAR project (INTERREG–V 2017-2020). The results and findings delivered have been published in the paper “Maritime spatial planning supported by infrastructure for spatial information in Europe (INSPIRE)” (Abramic et al., 2018). Currently, there are difficulties in harmonising products, visions, maps and frameworks of maritime spatial plans delivered by countries sharing the same marine (sub)region. This is mainly due to the fact that maritime plans do not use a common symbology and data structure to describe maritime activities. A solution for this issue is to apply on a marine spatial plans, INSPIRE standards for data sets, layers and portrayals. The MarSP project was a perfect opportunity to finalise conceptual data model development and, what is more important, to test results applying it on the real use cases, developed in the Macaronesia (Azores, Madeira, Canaries) MSP process. Initially, the INSPIRE data model for terrestrial planning (Planned Land Use, Figure 1) was tested to see if it could be applied for MSP. Tests pointed out that the terrestrial data model is robust, and can map MSP’s, but it tends to lose detail and specific information on marine uses. To be applied for MSP, the Planned Land Use data model needs to be adapted for planning of the maritime activities in the marine space. Conceptual model was analyzed, adapted, applying data modeling techniques, adjusting for MSP requirements: 1. Developed conceptual MSP data model, extending Planned Land use, using Unified Model Language (Figure 2); 2. Extending spatial scope of the data model - from two-dimensional land planning to the three dimensions planning. Extended structure includes maritime activities within the sea surface, water column, seabed and subsoil, when land model consists mainly of land surface planning; 3. Developed specific maritime uses classification (including register), extending Hierarchical INSPIRE Land Use classification (HILUCS); 4. Developed MSP data model templates, using simplified and feature complex spatial data architectures. Different type of codification templates, for advanced, standard and rookie GIS users (gml, GeoPackage, Shapfile, available at Canaries MSP platform); 5. Styled Layer Descriptor (color & simbology layout) for MSP, based on International Hydrographic Organization standards. 6. Data specification document v1.0 for Maritime Spatial Planning INSPIRE data model MarSP 2nd capacity building workshop was a great opportunity to test MSP data model results. Participants were trained on how to apply MSP data model on selected use case (Madeira MSP draft), during the “hands on” session, discussing potential issues and technical solutions. MarSP

Knowledge of the distribution and extent of seagrass habitats is currently the basis of management and conservation policies of the coastal zones in most European countries. This basic information is being requested through European directives for the establishment of monitoring programmes and the implementation of specific actions to preserve the marine environment. In addition, this information is crucial for the quantification of the ecological importance usually attributed to seagrass habitats due to, for instance, their involvement in biogeochemical cycles, marine biodiversity and quality of coastal waters or global carbon budgets. The seagrass atlas of Spain represents a huge collective effort performed by 84 authors across 30 Spanish institutions largely involved in the scientific research, management and conservation of seagrass habitats during the last three decades. They have contributed to the availability of the most precise and realistic seagrass maps for each region of the Spanish coast which have been integrated in a GIS to obtain the distribution and area of each seagrass species. Most of this information has independently originated at a regional level by regional governments, universities and public research organisations, which explain the elevated heterogeneity in criteria, scales, methods and objectives of the available information. On this basis, seagrass habitats in Spain occupy a total surface of 1,541,63 km2, 89% of which is concentrated in the Mediterranean regions; the rest is present in sheltered estuarine areas of the Atlantic peninsular regions and in the open coastal waters of the Canary Islands, which represents 50% of the Atlantic meadows. Of this surface, 71.5% corresponds to Posidonia oceanica, 19.5% to Cymodocea nodosa, 3.1% to Zostera noltii (=Nanozostera noltii), 0.3% to Zostera marina and 1.2% to Halophila decipiens. Species distribution maps are presented (including Ruppia spp.), together with maps of the main impacts and pressures that has affected or threatened their conservation status, as well as the management tools established for their protection and conservation. Despite this considerable effort, and the fact that Spain has mapped wide shelf areas, the information available is still incomplete and with weak precision in many regions, which will require an investment of major effort in the near future to complete the whole picture and respond to demands of EU directives.

A total of 173 taxa of seaweeds have been identified from the Selvagens Isles as result of a recent Research Expedition (MACARONESIA 2000, May 1999), with samples from intertidal and subtidal habitats. 66 taxa (53 species + 13 genera) are new records for the islands. Ficogeographically, the results presented here increase the number of amphiatlantic species and confirmed several others species with restricted distribution in the Macaronesia s.s. archipelagos (Madeira, Selvagens and Canaries) as defined by Prud'homme van Reine & van den Hoek (1990) 0
