  • 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).The crustaceans campaigns are usually held in June/July with the ship “Noruega” and cover the extension of the Portuguese coast of Alentejo and Algarve.

  • Identification and enumeration of harmful and potentially toxic phytoplankton species from water samples collected weekly in shellfish production areas, coastal and transition in mainland Portugal since the year 2014. These analyzes are part of the national system of monitoring bivalve mollusc production areas of IPMA and are considered in the zoning and in making decisions regarding their status. The data is collected for the requirements of Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004.

  • Digital archive of the analyzes of the surface charts of 00 UTC and 12 UTC, held in IM and IPMA Weather Forecast Center since October 2015. In the surface analysis charts, the isobars are filled up every 5 hPa, the high pressure centers (A) and the low pressure centers (B). Frontal surfaces, crest lines, valley lines, lines of instability and convergence are represented according to the standards established by the WMO. This compilation is in digital format (pdf) with a total of 1094 charts.
