Geology and Geomorphology of offshore Portugal in the Quaternary period, using as reference the Geological Chart of the Immersed Area, Scale 1: 2 000 000, of the Geological Chart of Portugal, Scale 1: 1 000 000. National Laboratory of Energy and Geology (LNEG) 2010 .

Volcanic centres in the Portuguese offshore, located between the Mid-Atlantic Rift zone (Azores archipelago) and the continental margin.

Location of structures resulting from the submarine fluids emissions, such as: mud volcanoes (methane hydrates); Pockmaks (methane) and hydrothermal vents (fluids enriched in salts and metallic elements), located between the Mid-Atlantic Rift zone (Azores archipelago) and the continental margin.

This layer provides geographic information related to a Omega calcite saturation in the seabed of the Azores (Orr 2005)

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.

This layer provides geographic information related to a Seafloor silicate concentration in the Azores.

This layer provides geographic information related to the polymetallic nodules distribution in the Azores, based on the International Seabed Authority organisation.

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).
