  • Joint campaigns of the TOPOMED and FREEZE projects sponsored by the Portuguese Foundation for Science and Technology (FCT). These two projects share complementary and objective areas of study. The first focuses on the effects of neotectonics on the evolution of landscape and environments and the second on the investigation of underwater discharges of fresh water.

  • Notifications concerning marine casualties and marine incidents occurring in the Portuguese territorial waters and in internal waters and with Portuguese flaged vessels in any part of the world.

  • Web Map Visualization, INSPIRE (ISO19128-WMS 1.3.0) compliance, of the: delimitation of portuguese coastal monitoring areas, 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; Artificial reef complexes deployed by IPMA off the Portuguese coast, Algarve and Nazaré, to serve as instruments for the revitalization of coastal ecosystems, coastal fisheries management and integrated coastal management.

  • 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.

  • TAGUSDELTA geophysical campaigns aim to collect the necessary information to elaborate the high resolution 3D seismic stratigraphy of the Tagus Delta.

  • ASTARTE geophysical campaigns aim to collect the necessary information for the assessment, strategy and risk reduction for Tsunamis in Europe.

  • Joint campaigns of the ERSTA and SANDEX projects, the ERSTA project is designed to study seismogenic and tsunamigenic bodies and to prepare a seismotectonic model for the Algarve region, the SANDEX project aims to evaluate the physical impact of sand and gravel extraction on the sedimentary balance and the evolution of the coastline.

  • The Tagusdelta campaign had technical and scientific objectives. The main technical objective was to make the proof of concept of the new proposed method for the acquisition of 3D very high resolution seismic reflection data. The accomplishment of this objective included: deployment and data acquisition systems tests; positioning uncertainty assessment; seismic and positioning data processing for the 3D seismic volume generation. From the scientific point of view the main objective was to acquire very high resolution seismic reflection data that allow the characterization of the frontal area of the Tagus ebb-tide delta seismic stratigraphic facies arquitecture. A special focus was placed in the: identification, characterization and mapping of mass wasting features, in order to allow a first trial of the Pleisto-Holocene mapping and chronostratigraphy of these features in the Tagus delta; imaging the morphologies of landslide structures with 3D seismic, particularly in what concerns the landslide already identified with the previous data, to allow the quantification and precise location of the events, to generate data of unprecedented realism that can be fed into the tsunamigenic mathematical models.

  • The ERSTA project intended to study the seismogenic and tsunamigenic bodies and prepare an sismotectonic model for the Algarve region. For this project, in this campaign, was intend to carry out a geophysical survey that will contribute to a more detailed characterization, in the offshore region, of São Marcos-Quarteira and Carcavai faults. The SANDEX project aims to evaluate the physical impact from the extraction of sand and gravel in the coastal sediment balance and evolution of the coastline. The campaign aims to collect bathymetric data that will contribute to monitoring of the impact caused by the exploitation of sand deposits carried off the Quarteira as well as for the assessment of sediment budget of the study area.

  • 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.
