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.
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.
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.
