Limits used for the issuance of Meteorological Forecast Reports for Maritime Navigation in the areas of sea of national responsibility (Mainland Portugal, Azores and Madeira), inserted mainly in METAREA II, according to the standards defined by the Global Maritime Distress and Safety System (GMDSS).

The current artificial reefs were deployed, starting with a pilot project in 1990, in order to serve as instrument for the revitalization of coastal ecosystems, planning of coastal fisheries and integrated coastal zone management. Each reef is composed by, at least, 2940 concrete modules with a weight of 3 tons and 36 large modules with more than 40 tons each. The reef complex groups 20,748 modules (with a total volume of over 100,000 m3), occupying discontinuously a total area of approximately 43.5 km2, with an area of influence greater than 67 km2.

Within Portugal's National Biological Sampling Project (PNAB) a set of activities are conducted in the collection, management and use of biological data, collected from the registered commercial fleet in mainland Portugal (fisheries-dependent data) and several research surveys (independent fisheries data). These activities allow the assessment of the state of fishery resources, population structure, distribution and abundance of resources, diversity and dynamics of biological communities associated with the fishery resources and biological studies (growth, reproduction).This resource shows the geographic distribution of european hake abundancy index (nr. individuals/hour) registered during the DEMERSAL2010 campaign in September 2010.

IPMA conducts regularly, since 1996, monitoring campaigns of bivalve molluscs banks that occur in the oceanic coast of the South West zone, in order to assess their condition. These campaigns allow the adjustment of the fishing effort and fishing quotas to the state of resources in order to not compromise its sustainability.This resource shows the geographic distribution of white clam biomass index (g/5 minutes per drag) recorded during the bivalve banks monitoring campaign held in June 2014.

Delimitation of portuguese coastal shellfish waters, according to the Law nº 236/98 and the European Directive 2006/113/EC concerning the protection of the aquactic environment and improvement of water quality in order to support shellfish (bivalve and gasteropod molluscs) life and growth and thus to contribute to the high quality of shellfish products directly edible by man, as well as the evaluation of the quality of coastal shellfish waters - Conformity according to Directive 113/2006 / EC, excluding the metals silver (Ag) and Arsenic (As), and fecal coliforms.

Delimitation and classification of coastal and estuarine-lagoon areas of molluscs and bivalve production located in the mainland published by Diário da República (the Portuguese Official Gazette) Nº. 78/2015, 2nd series of 2015-04-22, Order Nº. 4022/2015 including the additions published by Diário da República Nº. 188/2016, 2nd series of 2016-09-29, Order Nº. 11610/2016. See also rectification statement no. 1077/2016 (in rectification of order no. 11610/2016) published by Diário da República, 2nd series, no. 211 of November 3, 2016. To check the status of classification and / or the most current bans associated with the areas it is recommended to consult the IPMA page dedicated to the matter from 'http://www.ipma.pt/en/pescas/bivalves'.

This spatial dataset is part of the High Value Datasets/HVD identified in agreement with Implementing Regulation 2023/138 of Directive (EU) 2019/1024 on open data and the re-use of public sector information. The CONVERT project aimed at identifying, in an objective and quantitative way, the different types of endogenous biomass that can be applied in the short-medium term to economically viable technological solutions for the production of power and heat, energy vectors, and especially advanced biofuels. These should comply with all the sustainability criteria set by the European Directives, in particular the Red II (2015/1513) Directive. This project included the following activities: Activity 1 - Energy potential of the organic fraction of solid urban waste; Activity 2 - Energy potential of biowaste produced under industrial context; Activity 3 - Potential of mainland Portugal for energy crops; Activity 4 - Conversion technologies and respective energy products; Activity 5 - Life Cycle Analysis and estimation of Sustainable Value and Activity 6 - Communication plan. As part of Activity 3, LNEG developed a spatial data infrastructure to facilitate the exchange and use of information between all the beneficiary agents in a first phase, with visualization and consultation via the web. These data are crucial for choosing locations for energy crops/microalgae and for selecting the species to cultivate, while also identifying critical or limiting locations for their utilisation.
