Established in 1960 as a Portuguese Navy unit, Instituto Hidrográfico is presently a state laboratory, with scientific competences in the areas of hydrographic surveying, safety of navigation, oceanography, marine geology and chemistry.
The main research areas in the last few years covered the dynamics of continental shelf and slope waters and interaction with the deep-sea circulation, physical and sedimentary impacts of river inputs to the shelf, geological characterization of continental shelf and slope, submarine canyon dynamics, operational oceanography, including the use of data assimilation models in Oceanography.
