  • 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.

  • 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).

  • The TOPOMED-FREEZE campaign was organized as a joint campaign of the TOPOMED and FREEZE projects sponsored by the Fundação para a Ciência e a Tecnologia (FCT) (Plate reorganization in the western Mediterranean: lithospheric causes and topographic consequences, TOPOEUROPE/0001/2007; Submarine FREshwater dischargEs: characteriZation and Evaluation study on their impact on the Algarve coastal ecosystems, PTDC/MAR/102030/2008). These two projects share complementary study areas and objectives. The first concentrates on the effects of neotectonics on the evolution of landscape and environments and the second on the investigation of Submarine Fresh-Water Discharges.

  • 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.
