  • 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.

  • 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 FREEZE 2010 geophysical cruise was planned to acquire a detailed bathymetry just off Olhos d'Agua, high resolution seismic and Side Scan Sonar data in order to investigate and define the geological and the tectonic settings off Olhos d'Agua (Algarve coast, South Portugal) and to find any possible evidence of supposed existing submarine groundwater discharges (SGDs) in this area.

  • Produção de cartografia numérica vectorial à escala 1: 10 000 para o concelho do Bombarral. Esta informação encontra-se no Sistema de Referência PT-TM06/ETRS89 e a referência vertical é o Datum Altimétrico de Cascais Helmert 38.

  • A campanha sísmica ASTARTE 2014 tem como objetivo estender a área de levantamentos sísmicos anteriores até a uma distância de cerca de 20 milhas náuticas a partir da costa até a borda da plataforma continental. O planeamento da campanha contempla a aquisição de 24 perfis divididos em duas classes: uma classe em linha perpendicular à costa e uma classe em linha cruzada ortogonal às anteriores. A principal razão para selecionar a região ao largo da Quarteira é porque esta região é um alvo de registos de tsunamis na plataforma continental, embora toda a costa do Algarve possa ser um repositório de registros geológicos de tsunamis passados.

  • 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).

  • Digital archive of the analyzes of the surface charts of 00 UTC and 12 UTC, held in IM and IPMA Weather Forecast Center since October 2015. In the surface analysis charts, the isobars are filled up every 5 hPa, the high pressure centers (A) and the low pressure centers (B). Frontal surfaces, crest lines, valley lines, lines of instability and convergence are represented according to the standards established by the WMO. This compilation is in digital format (pdf) with a total of 1094 charts.

  • 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.
