The Geological Survey conducted on the south coast of the island of Porto Santo, aimed at the characterization of underwater morphology and sedimentary cover between the coastline and 100 meters deep. This project is the result of an agreement made between the Hydrographic Institute and the Regional Government of Madeira.
Surveys of 20 bathymetric profiles along the Porto Santo bay were made, distanced 500 meters from depth of -10 meters to the shoreline, and its orientation as perpendicular as possible to the bathymetry.
The multidisciplinary study carried out on the south coast of Madeira Island between Cabo Girão and the Ponta de S. Lourenço, aimed at the study of sediment dynamics between the coastline and 100 m depth. This project is the result of an agreement made between the Hydrographic Institute and the Regional Government of Madeira.
The project focused on Porto Santo Beach and contemplated topographic surveys carried out using the Trimble 5700 GPS RTK (with planimetric accuracy of 1 cm and altimetry precision of 2 cm) and hydrographic surveys carried out using the Trimble 5700 GPS RTK, Raytheon DE719D echosounder and Knudsen 320 M/P echosounder with centimeter accuracy. The fieldwork processed in three distinct phases: July 2006, January 2007 and July 2007.
Reference areas, points and delimiting data where the general conditions are applied as defined in the management plans and management of classified areas.
The work carried out intended to complement existing data, especially with regard to the morphological, sedimentary and physics study area. Considering the limited information available, it was proposed an exhaustive survey and as complete as possible, divided into five complementary areas. For logistical and operational issues, each of these areas was performed independently, with different technical teams. Seagoing work took place on board the vessel "S.Roque" (owned by the Autonomous Region of Madeira). Subsequent to the field work, laboratory analysis of the collected sample was held at the facilities of the Hydrographic Institute in Lisbon.
Excel and shapefile datasets, including geo-referenced data of opportunistic cetacean sightings in the Madeira Archipelago waters.
Access Databases, Excel and shapefiles, including geo-referenced data of cetacean and sea turtle sightings, surface waste, marine traffic and environmental conditions. It also includes the routes of transects in point and polylines formats.
Geophysical surveys and sedimentological study of surface samples of the sedimentary cover to delimitation, quantification and characterization of sedimentary deposits on the south coast of Madeira Island. This project is the result of a protocol made between the Hydrographic Institute and the Regional Government of Madeira.
