  • Sedimentological characterization of part of the continental shelf. Folk classification (7 classes).

  • 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.

  • 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).

  • Earthquakes (epicenters) and areas that mark large submarine landslides of sedimentary material, which caused tsunamis whose impact was recorded on the Portuguese coast.

  • 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.

  • The Nazaré Artificial Reef deployed in 2010, covering an area of apr. 3 Km2 was a public project commissioned by the Nazaré Council, with the technical and scientific support of the multidisplinary research team from IPMA.

  • 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.

  • Areas that evidence the occurrence of submarine landslides, located between the Middle Atlantic Rift zone (Azores archipelago) and the Continental margin.

  • Database that stores and catalogues thin sections and polished surfaces, as well as the corresponding source samples, providing a valuable resource for the scientific community.

  • 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.
