Ocean thermal fronts are produced daily "detected" with the SIED algorithm - Single Image Edge Detection (Cayula and Cornillon, 1992) applied to satellite images of the sea surface temperature (SST), made available by the CMEMS (Copernicus Marine Environment Monitoring Service) and DEIMOS, is run by Meteo France CMS over EUROPE.

Microbiological monitoring of bivalve mollusc production areas in mainland Portugal, since the year 2014, performed by quantification of Escherichia coli in meat and liquid intravalvular live bivalve, according to the sample planning. 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 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.

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.

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.

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.

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.
