Areas that evidence the occurrence of submarine landslides, located between the Middle Atlantic Rift zone (Azores archipelago) and the Continental margin.
The Portuguese Mineral Occurrences and Resources Information System (SIORMINP) provides access to geoscientific, technical and economic information on occurrences, reserves and resources, associated commodities, geology, mines, mining activities, mining wastes and areas with mining potential known in mainland Portugal.

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.
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 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.
The ASTARTE 2014 seismic campaign aims extending the area of previous seismic surveys to a distance of around 20 nautical miles from the coast till the edge of the continental shelf. The survey plan was made for acquisition of 24 profiles divided in two classes: the in-line class perpendicular to the coastline and the cross-line class orthogonal to the in-line lines. The main reason for selecting the offshore Quarteira region is because this region is a target for tsunami in prints on the continental shelf although the entire Algarve coast can be a repository of past tsunami geologic records.
