The Spanish Institute of Oceanography has realized nineteen oceanographic cruises in order to monitor the geomorphological changes during the submarine eruption of the Tagoro volcano and later evolution. The major geomorphological features were achieved fundamentally by the use of Multibeam EM710 echosounder data. Eruption was characterized by two...
The shallow Tagoro submarine volcano monitoring represents a unique opportunity not only for improving our sparse understanding of submarine volcanic processes in specific scientific fields as physical and chemical oceanography or marine geology but also its interactions over the marine biology in one of the richest marine ecosystems in Europe. Thi...
About 80% of the marine litter found in the marine environment comes from land-based activities being an extremely complex and damaging pressure for the environment. The Canary Islands have 1501 km of coastline but until late 2020, the impact generated by accumulation of marine debris on coastline had no specific monitoring plans that addressed thi...
Seabed mapping techniques have improved over the last decades in accordance with the increasing needs of obtaining high-resolution information. In this sense, the use of single-beam echo-sounders is now combined with multi-beam ones in order to gain data accuracy. In the framework of oceanography surveys carried out by the R/V R. Margalef performed...
The Spanish Institute of Oceanography is responsible, among other aspects, for scienti c and technical advice for the Government's sheries policy as well as for the protection and sustainability of the marine environment. In this task, it generates a large amount of oceanographic data characterized by its spatial dispersion during acquisition as we...
In Europe, the Marine Strategy Framework Directive (MSFD) seeks to achieve a good environmental status of European marine waters and protect the resource base on which economic and social activities related to the sea depend. With this legislative tool the European Parliament recognizes the vital importance of the management of human activities tha...
Tagoro, the shallow submarine volcano that erupted south of El Hierro (Canary Islands, Spain) in October 2011, has been intensely monitored for over 7 years, from the early eruptive stage to the current degassing stage characterized by moderate hydrothermal activity. Here, we present a detailed study of the emissions of inorganic macronutrients (NO...
Macaronesian Maritime Spatial Planning (MarSP) project was a perfect opportunity to finalize conceptual MSP INSPIRE data model development and, what is more important, to test developed data model and apply it on the real use cases, developed in the Macaronesia MSP process. During the 2nd MarSP technical workshop – capacity building, held in March...
Europe's Blue Growth strategy promotes the intensification of human activities at sea and increases the environmental risk such as the decline of the provision of key ecosystem services and potential conflicts among human activities. The fishing sector, in the Alboran Sea, is economically and culturally one of the most important and relies on overe...
The Spanish Institute of Oceanography was created in 1914, it is a public research organization dedicated to reseach in marine science, especially in relation to scientific knowledge of the oceans, sustainability of fishing resoureces and the marine environment. The researches performs multidisciplinary studies of the marine environment, as well as...
We analyzed and discussed the types of distribution, existing for 117
species of demersal fishes distributed along the North Alborán Sea, Gulf of Vera, and Balearic Sea (Alicante, Ebro Delta and Blanes coast). Data from 19 consecutive years (1994-2012) surveys, with similar sampling protocol, were used to characterise the demersal fishes assemblage...
Complex multifault earthquake ruptures involving secondary faults emphasize the necessity to characterize their seismogenic potential better and study their relationship with major faults to improve the seismic hazard assessment of a region. High-resolution geophysical data were interpreted to make a detailed characterization of the Averroes Fault...
CODIIGE (Executive Board of the Geographic Information Infras-tructure of Spain) has created Thematical Working Groups (TWG) with the main objective of analyzing how apply the INSPIRE data specifications for transforming the Spatial datasets produced by Spanish public orgnizations and help them to be INSPIRE conformant and promote data interoperabi...
Report on the environmental monitoring (geophysics, seabed sampling, physical and chemical characteristics, and planton) made on the submarine volcano of Tagoro (El Hierro Islands) to evaluate the degree of affection and recovery on the marine ecosystem of the last volcanic eruption in the Canary region, making it extendable to other regions of the...
Report on the geophysics and seabed sampling made on the submarine canyon of Algeciras to know its geological, geomorphological and benthic characteristics. In addition, a series of underwater mounds were studied in two sectors of the northern margin of the Alboran Sea.
Between October 2011 and March 2012 a submarine volcanic eruption took place at the offshore of El Hierro Island. The extensive study of the eruption and subsequent degassing process has allowed monitoring the newly generated volcanic edifice. Multibeam bathymetric has enabled building a digital high-resolution bathymetric model (grid 1x1 m). The p...
This Good Practice Guide is the outcome of a project co-funded by the European Commission (DG Mare) called Transboundary Planning in the European Atlantic (TPEA), which ran from December 2012 to May 2014. The aim of the project was to demonstrate approaches to transboundary maritime spatial planning (MSP) in the European Atlantic region. This is on...
A small amount of the total strain produced by the convergence between the Nubian and Eurasian plates is accommodated in the Alboran Sea basin by different fault systems. High resolution bathymetric maps show several NE-SW lineaments across the Djibouti High, among them the Djibouti fault, that have lengths up to 30 km and are apparently offsetting...
