  • This project aims to characterize the evolution of the coastline during the Quaternary and discern what were the contributions to this evolution: 1) neotectonic, 2) eustatic variations and 3) sedimentary transport; for this purpose was selected as study area the coastal stretch between Cabo da Roca (~ 38 46'N) and the village of Comporta (~ 38 20'N).

  • 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 spring acoustic surveys are usually held in April/May with the ship "Noruega" and cover the Portuguese continental waters and the Spanish waters of the Gulf of Cadiz, between 20 and 200m deep.

  • Quantification of contaminant metals including mercury, lead and cadmium in bivalve harvested semiannually in bivalve mollusc coastal and transition production areas in mainland Portugal since the year 2014. These analyzes are part of the National monitoring system of bivalve mollusc production areas and are considered in the classification of these areas and in the decision-making relative to their status. The data is collected according to the Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004.

  • Ocean thermal fronts are produced daily "detected" with the SIED algorithm - Single Image Edge Detection (Cayula and Cornillon, 1992) applied of the sea surface temperature in the HYCOM model (HYbrid Coordinate Ocean Model) available at DEIMOS and provided / supplies by IH.

  • The ASTARTE 2014 seismic campaign aims extending the area of previous seismic surveys to a distance of around 20 nautical miles from the coast till the edge of the continental shelf. The survey plan was made for acquisition of 24 profiles divided in two classes: the in-line class perpendicular to the coastline and the cross-line class orthogonal to the in-line lines. The main reason for selecting the offshore Quarteira region is because this region is a target for tsunami in prints on the continental shelf although the entire Algarve coast can be a repository of past tsunami geologic records.

  • Marine biotoxins monitoring of bivalve molluscs in classified production areas in mainland Portugal, since 2014, at intervals defined in the respective sampling plan, through the detection and quantification of the various groups of marine biotoxins laid down in Regulation (EC) 853 / 2004 in live bivalve tissues. These analyzes are part of the national monitoring of bivalve molluscs production areas and are considered in the official control system for decision-making concerning health rules applicable to bivalve in the various production areas. The data is collected according to the requirements of Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004 and the rules set out in Decree No. 1421/2006 of the Ministries of Economy and Innovation and Agriculture, Rural Development and Fisheries of 21 December 2006.
