Background: In a situation of compulsory home isolation enacted by governments at the spreading of the Covid-19 pandemic, the emotional health and well-being of students became a key factor in the successful implementation of distance teaching methodologies in face-to-face education universities. Psychological well-being, an essential factor in preventing academic failure, has been threatened in this serious situation of unprecedented and stressful isolation. The aim of this study is to analyze the students' cognitive-emotional regulation as well as their beliefs and perceptions about the pandemic and this lockdown situation. With this extensive study we are carrying out, want to describe the extent to which the lockdown situation is a risk factor, and, in the future, make proposals for preventive and palliative actions, if necessary, to minimize this potential risk. Method: We applied the CERQ Cognitive Emotion Regulation Questionnaire by means of an online application together with a questionnaire, CC/covid-19, of objective description and subjective perception of the lockdown situation of the students, their conditions to study, general opinions about the pandemic and specific opinions about the real possibilities of implementing online education in the middle of the academic year at the university. 1910 valid responses from more than 80 universities in 13 different Spanish-speaking countries were obtained and submitted to descriptive analysis and modeling using structural equations. Results: Most of them consider that the lockdown decision is correct, that health systems are not prepared to deal with the pandemic, and that although the universities have adequate means, the teaching staff is not competent to implement online teaching methodologies. They have a good perception of the conditions of isolation, however, the time devoted to studying has not increased. One of the results of our study is the students' self-evaluation about their digital competence and their capacity to perform

Tintoré et al. Sustained Mediterranean Observing Forecasting SystemThe Mediterranean community represented in this paper is the result of more than 30 years of EU and nationally funded coordination, which has led to key contributions in science concepts and operational initiatives. Together with the establishment of operational services, the community has coordinated with universities, research centers, research infrastructures and private companies to implement advanced multi-platform and integrated observing and forecasting systems that facilitate the advancement of operational services, scientific achievements and mission-oriented innovation. Thus, the community can respond to societal challenges and stakeholders needs, developing a variety of fit-for-purpose services such as the Copernicus Marine Service. The combination of state-of-the-art observations and forecasting provides new opportunities for downstream services in response to the needs of the heavily populated Mediterranean coastal areas and to climate change. The challenge over the next decade is to sustain ocean observations within the research community, to monitor the variability at small scales, e.g., the mesoscale/submesoscale, to resolve the sub-basin/seasonal and inter-annual variability in the circulation, and thus establish the decadal variability, understand and correct the model-associated biases and to enhance model-data integration and ensemble forecasting for uncertainty estimation. Better knowledge and understanding of the level of Mediterranean variability will enable a subsequent evaluation of the impacts and mitigation of the effect of human activities and climate change on the biodiversity and the ecosystem, which will support environmental assessments and decisions. Further challenges include extending the science-based added-value products into societal relevant downstream services and engaging with communities to build initiatives that will contribute to the 2030 Agenda and more specifically to SDG14 and the UN's Decade of Ocean Science for sustainable development, by this contributing to bridge the science-policy gap. The Mediterranean observing and forecasting capacity was built on the basis of community best practices in monitoring and modeling, and can serve as a basis for the development of an integrated global ocean observing system.

Closure dams in estuaries and tidal areas have a strong impact on their hydrodynamics and morphology. Among other reasons, this impact can be due to tidal reflection. In the Guadalquivir estuary (SW Spain), data measured allowed to identify a partially standing motion along the upper third of the estuary. We estimate the frequencydependent complex reflection coefficients at the head dam, and analyze the effect of the combined action of the incident and reflected tidal waves on the residual currents. Erosion-deposition patterns induced by the tidal reflection were identified. The most energetic tidal constituent, the semidiurnal M2, favors sedimentation near the entrance of the Port of Seville, where the most intense dredging works take place. Finally, we briefly discuss the potential consequences of reflection on the turbidity spatial distribution.

En la Universidad del Siglo XXI, la función de liderazgo está en la base de los procesos de surgimiento, mantenimiento e institucionalización de una nueva cultura de la calidad (Fernández Cruz, 2015).En este contexto, las universidades han creado unas Unidades de Calidad como responsables de los procesos de acreditación, seguimiento y renovación de títulos que deben actuar como verdaderos impulsores de unas acciones de mejora para las que resulta indispensable la puesta en marcha de procesos de evaluación y seguimiento que exigen el ejercicio de un liderazgo que fomente una cultura de calidad que impregne el quehacer diario de la institución.Los nuevos Títulos de Grado establecidos dentro del Espacio Europeo de Educación Superior demandan una serie de actuaciones que deben ser ejecutadas por los llamados Coordinadores de Grado como responsables de la coordinación de los equipos docentes.Además de lo anterior, el proceso de internacionalización que conlleva el Espacio Europeo de Educación Superior supone el desarrollo de estrategias de liderazgo a nivel interno, que se han traducido hacia el exterior en un fuerte liderazgo institucional (Cleveland-Innes, 2012; Juárez-Casalengua, 2015), y en un impulso y liderazgo político e institucional de la UE.Por otra parte, y dado que la mayoría de los trabajos de investigación sobre liderazgo se han centrado tradicionalmente en los cargos directivos, hemos querido abordar desde una óptica alternativa la función de liderazgo que ejercen los estudiantes universitarios mediante los diferentes cargos de representación que desempeñan.Finalmente, dedicamos un apartado al estudio de la importancia que tiene la formación en liderazgo en los planes de estudio de los futuros maestros, comprobando que ante la carenciade una formación suficiente, los maestros buscan su preparación en el ejercicio del liderazgo fuera de su formación inicial: a través de cursos de formación continua o incluso de Másteres.

Abstract. The AlborEX (Alboran Sea Experiment) consisted of a multi-platform, multi-disciplinary experiment carried out in the Alboran Sea (western Mediterranean Sea) between 25 and 31 May 2014. The observational component of AlborEx aimed to sample the physical and biogeochemical properties of oceanographic features present along an intense frontal zone, with a particular interest in the vertical motions in its vicinity. To this end, the mission included 1 research vessel (66 profiles), 2 underwater gliders (adding up 552 profiles), 3 profiling floats, and 25 surface drifters.Near real-time ADCP velocities were collected nightly and during the CTD sections. All of the profiling floats acquired temperature and conductivity profiles, while the Provor-bio float also measured oxygen and chlorophyll a concentrations, coloured dissolved organic matter, backscattering at 700 nm, downwelling irradiance at 380, 410, and 490 nm, as well as photo-synthetically active radiation (PAR).In the context of mesoscale and sub-mesoscale interactions, the AlborEX dataset constitutes a particularly valuable source of information to infer mechanisms, evaluate vertical transport, and establish relationships between the thermal and haline structures and the biogeochemical variable evolution, in a region characterised by strong horizontal gradients provoked by the confluence of Atlantic and Mediterranean waters, thanks to its multi-platform, multi-disciplinary nature.The dataset presented in this paper can be used for the validation of high-resolution numerical models or for data assimilation experiment, thanks to the various scales of processes sampled during the cruise. All the data files that make up the dataset are available in the SOCIB data catalog at https://doi.org/10.25704/z5y2-qpye (Pascual et al., 2018).
