El IEO se adhiere a la Iniciativa de Acceso Abierto de Budapest
On 15 February 2017, the Spanish Institute of Oceanography formalized its adhesion to the Budapest Open Access Initiative (BOAI). The BOAI was the first to define the term “open access” as the free availability on the public Internet of the full texts of peer-reviewed research literature, and its definition is frequently cited in the context of open access policies, practices, and laws around the world. The BOAI is a groundbreaking initiative that has been widely embraced by stakeholders, and that has stimulated significant progress toward the global understanding and adoption of open access to academic research, much of which is publicly funded.El 15 de febrero de 2017, el Instituto Español de Oceanografía oficializó su adhesión a la Iniciativa de Acceso Abierto de Budapest (BOAI).

Scientific dissemination in the Instituto Español de Oceanografía (IEO): Best practices in recent years
There is a growing interest and obligations to
bring the results of scientific research closer to society. In this
sense, the Instituto Español de Oceanografía (IEO, CSIC) has
acquired in recent years an institutional commitment with the
scientific dissemination, carrying out some projects on this
topic. The objective of these projects is to visualize and value
their research and results in different formats increasing the
scientific culture of society that demand and financed most of
public research. In the present work four successful initiatives
or projects are presented. Diversimar project is a citizen
science tool for the observation of the marine and fishing
biodiversity of Galicia and the Cantabrian Sea. Mar interior
project brings activity of IEO to society with face-to-face
conferences and workshops. Planet Tuna project combines
science with art through an online platform to enhance the
scientific knowledge of tuna and other big pelagics for their
sustainability. To end, the interactive book “45 days on the
Flemish Cap Bank” spreads the technical and human effort of
an oceanographic survey that remains behind the fisheries
management developed by the IEO. The objective of the
present study is to make visible and put in value these projects
and serve as inspiration.Versión del edito
Deep-sea habitat characterization using acoustic data and underwater imagery in Gazul mud volcano (Gulf of Cádiz, NE Atlantic)
Gazul is the shallowest mud volcano (MV) within the Shallow Field of Fluid Expulsion (SFFE) of the northeastern Gulf of Cádiz (NE Atlantic; 300–1200 m depth). The SFFE represents an important geo- and biodiversity area that was designated as a Site of Community Importance under the European Habitats Directive in 2014. In this study, geological features, habitats and associated biodiversity, as well as anthropogenic impacts, were characterized at Gazul MV from underwater imagery and multibeam bathymetry. Multivariate methods using the Bray-Curtis similarity index identified six main habitats, each of which harbored a characteristic faunal assemblage that included: (1) sandy ripple bottoms typified by the actiniarian Actinauge richardi; (2) sandy, muddy, coarse sand and bioclastic bottoms dominated by the solitary coral Flabellum chunii; (3) coarse sand and bioclastic bottoms, together with soft sediments covered by scattered methane-derived authigenic carbonates (MDACs) (mixed bottoms), characterized by the echinoid Cidaris cidaris; (4) hard bottoms comprising MDACs dominated by a wide variety of sponges and gorgonians; (5) coral-rubble bottoms typified by the presence of colonial scleractinian communities dominated by Madrepora oculata; and (6) mixed bottoms characterized by the presence of a styelid ascidian. Slope and water depth were the main factors explaining assemblages’ distribution, which was also supported by the presence of MDACs such as slabs, crusts and chimneys on the seafloor, as well as by the geomorphologic diversity of Gazul MV. The results highlight Gazul MV as an eco-biologically important area harboring different vulnerable marine ecosystem (VME) elements with indicator taxa such as scleractinians, sponges, gorgonians and black corals. ROV images revealed abandoned or lost fishing gears and marine debris on the seafloor, indicating anthropogenic impacts in Gazul MV and adjacent areas. Indeed trawling fisheries activities have also been detected in Vessel Monitoring System datasets. A fishery restricted area is recommended in Gazul MV due to the occurrence of diverse VMEs and species included in different conservation directives and conventions.Postprin
Effect of fluid emissions in the acoustic response on the seabed of the Gulf of Cádiz
Advances in remotely-sensed techniques have revolutionized mapping methods and our
understanding of the seabed environment. In particular, multibeam backscatter data nowadays
allows developing quantitative studies on the composition of the seafloor, which represents an
important baseline for habitat mapping. Usually, the acoustic response is considered as a direct
proxy of sediment texture, but seepage could affect significantly this relationship. A multibeam data
set from the Gulf of Cádiz, was grouped using an ISO-cluster analysis and results were compared
with 80 ground-truthing stations taken inside and outside cold seepage areas. Results show
significant differences between the acoustic response of sediments with the same texture depending
on the presence/absence of fluid emissions. Understanding this relationship is necessary to make
image-based backscatter classification that allows the production of sediment and habitat maps in
areas with extensive fluid emissions such as the Gulf of Cádiz.Versión del edito
Hydrography applied to the mapping of submarine volcanoes
Technical advances in hydrographic studies of the seafloor and the progressive use of
these techniques in oceanographic expeditions with scientific objectives, is generating greater
collaborations between the hydrographic and oceanographic institutions. Coordination between the
different institutions and the use of IHO criteria in the acquisition of bathymetric data in
oceanographic expeditions, allow regional hydrographic offices to have an additional source of data
for the improvement of the navigation charts. Meanwhile the Oceanographic Institutions will benefit
by having validated bathymetric data of high precision. This product is of great interest in studies of
submarine geological hazards where is necessary to have a very detailed knowledge of the seabed to
determine possible morphological changes associated with the risk processes and the possible active
structures. In addition, monitoring of active volcanoes need to have a good knowledge of changes in
the physico-chemical properties of the water column, the possible changes in low intensity emissions
(hot water, gas) can be detected with these studies in the overlying water masses.Versión del edito
Vulnerable marine ecosystems and biological features of Gazul mud volcano (Gulf of Cádiz): A contribution towards a potential "Gulf of Cádiz" EBSA
The Gulf of Cádiz (GoC) represents an area of socioeconomic and scientific importance for oceanographic, geological and biological processes. An interesting feature of the GoC is the presence of a large amount of mud volcanoes (MVs) and diapirs that display different seepage, seabed types, oceanographic settings and biological communities. Detailed exploration of some MVs is still needed for detecting Vulnerable Marine ecosystems (VMEs) that seem to be rare in other areas of the GoC, improving the current knowledge on its biodiversity and ecological attributes. During different expeditions (MEDWAVES-ATLAS, INDEMARES-CHICA 0610 & 0412 and ISUNEPCA 0616) carried out in different years, biological samples and videos were obtained in Gazul MV (Spanish Margin of the GoC). The study of those samples and videos has revealed the presence of several ecologically important VMEs (e.g. 3 species of reef framework-forming corals, coral gardens including solitary scleractinians, gorgonians and antipatharians, as well as deep-sea sponge aggregations and chemosynthesis-related structures) and a large number of species occurring in this MV, including new records for the European margin, threatened species and non-previously described species. The combination of different environmental and anthropogenic factors allowed the present-day persistence of these VMEs in the GoC. Some of Gazul MV biological and ecological attributes fit several criteria of the Convention on Biological Diversity for EBSA description (e.g. 1,3,4,6) that, together with those of other areas of the GoC, may contribute to the future potential nomination of an EBSA in this area of the NE Atlantic
Cruise Summary Report - MEDWAVES survey. MEDiterranean out flow WAter and Vulnerable EcosystemS (MEDWAVES)
The MEDWAVES (MEDiterranean out flow WAter and Vulnerable EcosystemS) cruise targeted areas under the potential influence of the MOW within the Mediterranean and Atlantic realms. These include seamounts where Cold-water corals (CWCs) have been reported but that are still poorly known, and which may act as essential “stepping stones” connecting fauna of seamounts in the Mediterranean with those of the continental shelf of Portugal, the Azores and the Mid-Atlantic Ridge. During MEDWAVES sampling has been conducted in two of the case studies of ATLAS: Case study 7 (Gulf of Cádiz-Strait of Gibraltar-Alboran Sea) and Case study 8 (Azores).
The initially targeted areas in the Atlantic were: the Gazul Mud volcano, in the Gulf of Cádiz (GoC) area, included in the case study 7, and the Atlantic seamounts Ormonde (Portuguese shelf) and Formigas (by Azores), both part of the case study 8. In the Mediterranean the targeted areas were The Guadiaro submarine canyon and the Seco de los Olivos (also known as Chella Bank) seamount. Unfortunately it was not possible to sample in Guadiaro due to time constraints originated by adverse meteorological conditions which obligate us to reduce the time at sea focusing only in 4 of the 5 initially planned areas.
MEDWAVES was structured in two legs; the first leg took place from the 21st September (departure from Cádiz harbour in Spain) to the 13th October 2016 (arrival in Ponta Delgada, São Miguel, Azores, Portugal took place the 8th of October due to the meteorological conditions that obligated to conclude the first leg earlier as planned). during the Leg 1 sampling was carried out in Gazul, Ormonde and Formigas. The second leg started the 14th October (departure from Ponta Delgada) and finished the 26th October (arrival in Málaga harbour, Spain). MEDWAVES had a total of 30 effective sampling days, being 6 days not operative due to the adverse meteorological conditions experienced during the first leg which forced us to stay in Ponta Delgada from the 08th to the 13th October.
During MEDWAVES the daily routine followed a similar scheme, depending of course on the weather and sea conditions. The main activity during the day, starting early in the morning (around 08:00 AM, once the night activities were finished), was the ROV deployment. Generally a single ROV dive of around 8 hours was performed, however in several occasions two dives were carried out in the same day (see General station list, Appendix II). After the ROV (and sometimes between two dives) the Box Corer and/or Van Veen Grab and/or Multicore was deployed. After these activities, during the night CTD-Rosette deployments and MB was conducted. Accordingly to this schema the scientific personnel worked in the day or in the night watch.
A total of 215 sampling stations have been covered in MEDWAVES, using the following sampling gears: Multibeam echosounder, CTD-Rosette, LADCP, Box Corer, Van Veen Grab, Multicorer and a Remotely Operated Vehicle (ROV). Table 1 sumamrised the number of sampling stations conducted with each gear in each sampling zone. Additionally MB surveys have been conducted during the transits between area
