There are several research infrastructures or other data services running in Europe that cover a multitude of marine-related sciences, providing specific datasets coming from observations collected with different methods. These infrastructures constitute a diverse world, each looking at a piece of the big picture, sometimes hindering collaboration and data sharing. Blue-Cloud aims to overcome fragmentation and build a bridge between thematic science clusters - such as marine, climate, food and agriculture sciences - and EOSC, creating a data federation and providing a common access to a so-called thematic EOSC for marine data. By connecting leading marine data management infrastructures with horizontal e-infrastructures, the project aims to maximise the exploitation of data resources available from different sources. The Blue-Cloud framework consists of two major technical components: (1) a Blue-Cloud Data Discovery and Access service, already presented in a previous EOSC in practice story, to serve federated discovery and access to blue data infrastructures, and (2) a Blue-Cloud Virtual Research Environment (VRE) to provide computing platforms and analytical services facilitating the collaboration between researchers, which is detailed hereafter. The Blue-Cloud VRE is powered by the D4Science Infrastructure. [M. Assante et al. (2019) Enacting open science by D4Science. Future Gener. Comput.

Despite the current high level of safety and the efforts to make passenger ships resilient to most fire and flooding scenarios, there are still gaps and challenges in the marine emergency response and ship evacuation processes. Those challenges arise from the fact that both processes are complex, multi-variable problems that rely on parameters involving not only people and technology but also procedural and managerial issues. SafePASS Project, funded under EU’s Horizon 2020 Research and Innovation Programme, is set to radically redefine the evacuation processes by introducing new equipment, expanding the capabilities of legacy systems on-board, proposing new Life-Saving Appliances and ship layouts, and challenging the current international regulations, hence reducing the uncertainty, and increasing the efficiency in all the stages of ship evacuation and abandonment process.

Microplastics are substrates for microbial activity and can influence biomass production. This has potentially important implications at the sea-surface microlayer, the marine boundary layer that controls gas exchange with the atmosphere and where biologically produced organic compounds can accumulate. In the present study, we used large scale mesocosms (filled with 3 m3 of seawater) to simulate future ocean scenarios. We explored microbial organic matter dynamics in the sea-surface microlayer in the presence and absence of microplastic contamination of the underlying water. Our study shows that microplastics increased both biomass production and enrichment of particulate carbohydrates and proteins in the sea-surface microlayer. Importantly, this resulted in a 3% reduction in the concentration of dissolved CO2 in the underlying water. This reduction suggests direct and indirect impacts of microplastic pollution on the marine uptake of CO2, by modifying the biogenic composition of the sea’s boundary layer with the atmosphere.

First-pass perfusion cardiac magnetic resonance (FPP-CMR) is becoming essential to detect blow flow anomalies. However, the need for real-time acquisitions limits the achievable spatial resolution and coverage of the heart. To keep both within a reasonable range, FPP-CMR needs to be accelerated. A SElf-Supervised aCcelerated REconsTruction (SECRET) DL framework is presented to speed-up reconstruction of FPP-CMR images from undersampled (k,t)-space data. The physical reconstruction models are used to train deep neural networks without requiring fully sampled images. SECRET achieves good quality reconstructions at a variety of acceleration rates, with significant speed-ups compared to the state-of-the-art.

Optical projection tomography is the optical analogue of X-ray tomography, a 3D mesoscopic imaging modality of the optical attenuation or fluorescence intensity distribution within transparent samples. As current limitations, the requirement of several hundreds of angular projections for filtered backprojection reconstruction leads to acquisition times of several minutes. While iterative methods allow to reconstruct images from sparsely sampled datasets, they convey several seconds, thus precluding from real-time reconstruction. Here we present a model-based unrolled network with a CNN as a regularization prior, trained on four zebrafish datasets. Based on an alternating algorithm, our network rapidly reconstructs high quality images from few projections within milliseconds. Youtube: https://youtu.be/4sNyq7zFEC8

Ten innovative EU projects to build ocean observation systems that provide input for evidence-based management of the ocean and the Blue Economy, have joined forces in the strong cluster ‘Nourishing Blue Economy and Sharing Ocean Knowledge’. Under the lead of the EuroSea project, the group published a joint policy brief listing recommendations for sustainable ocean observation and management. The cooperation is supported by the EU Horizon Results Booster and enables the group to achieve a higher societal impact. The policy brief will be presented to the European Commission on 15 October 2021. The ocean covers 70% of the Earth’s surface and provides us with a diverse set of ecosystem services that we cannot live without or that significantly improve our quality of life. It is the primary controller of our climate, plays a critical role in providing the air we breathe and the fresh water we drink, supplies us with a large range of exploitable resources (from inorganic resources such as sand and minerals to biotic resources such as seafood), allows us to generate renewable energy, is an important pathway for world transport, an important source of income for tourism, etc. The Organisation for Economic Cooperation and Development (OECD) evaluates the Blue Economy to currently represent 2.5% of the world economic value of goods and services produced, with the potential to further double in size by 2030 (seabed mining, shipping, fishing, tourism, renewable energy systems and aquaculture will intensify). However, the overall consequences of the intensification of human activities on marine ecosystems and their services (such as ocean warming, acidification, deoxygenation, sea level rise, changing distribution and abundance of fish etc.) are still poorly quantified. In addition, on larger geographic and temporal scales, marine data currently appear fragmented, are inhomogeneous, contain data gaps and are difficult to access. This limits our capacity to understand the ocean variability and sustainably manage the ocean and its resources. Consequently, there is a need to develop a framework for more in-depth understanding of marine ecosystems, that links reliable, timely and fit-for-purpose ocean observations to the design and implementation of evidence-based decisions on the management of the ocean. To adequately serve governments, societies, the sustainable Blue Economy and citizens, ocean data need to be collected and delivered in line with the Value Chain of Ocean Information: 1) identification of required data; 2) deployment and maintenance of instruments that collect the data; 3) delivery of data and derived information products; and 4) impact assessment of services to end users. To provide input to the possible future establishment of such a framework, ten innovative EU projects to build user-focused, interdisciplinary, responsive and sustained ocean information systems and increase the sustainability of the Blue Economy, joined forces in a strong cluster to better address key global marine challenges. Under the lead of the EuroSea project, the group translated its common concerns to recommendations and listed these in the joint policy brief ‘Nourishing Blue Economy and Sharing Ocean Knowledge. Ocean Information for Sustainable Management.’. Following up on these recommendations will strengthen the entire Value Chain of Ocean Information and ensure sound sustainable ocean management. In this way, the 10 projects jointly strive to achieve goals set out in the EU Green Deal, the Paris Agreement (United Nations Framework Convention on Climate Change) and the United Nations 2021-2030 Decade of Ocean Science for Sustainable Ocean Development. Toste Tanhua (GEOMAR), EuroSea coordinator: “It was great to collaborate with these other innovative projects and make joint recommendations based on different perspectives and expertise.”

Objectives: To explore deep-sea areas of the Azores EEZ to better understand the distribution patterns of large VME species and commercial fishes. Specifically, the objectives of the cruise were to (i) continue the characterization of benthic communities inhabiting the slopes of Terceira and neighboring submarine ridges, (ii) identify new areas that may fit the FAO definition of what constitutes a Vulnerable Marine Ecosystem; and (iii) to contribute with additional data to address patterns and drivers of the distribution of deep-sea benthic biodiversity in the Azores region. It will also provide valuable information in the context of Good Environmental Status (GES), Marine Spatial Planning (MSP) and provide new insights on how to sustainably manage deep-sea ecosystems. Vessel: R/V Pelagia Chief scientist: Fleur Visser (NIOZ) Scientific team: Manuela Ramos (IMAR-UAç) Cruise summary: Six new dives were performed by the towed camera system of R/V Pelagia during the cruise. Four dives were performed on the southern Terceira island depression, covering a depth range between 1300 and 1900 m. The remaining two dives were performed in the Serreta Ridge, WNW of Terceira, between 780 and 1100 m depth. Overall, we collected 6 h of new video footage.

Data products, based on in situ temperature and salinity observations from SeaDataNet infrastructure, have been released within the framework of SeaDataCloud (SDC) project. The data from different data providers are integrated and harmonized thanks to standardized quality assurance and quality control methodologies conducted at various stages of the data value chain. The data ingested within SeaDataNet are earlier validated by data providers who assign corresponding quality flags, but a Quality Assurance Strategy has been implemented and progressively refined to guarantee the consistency of the database content and high quality derived products. Two versions of aggregated datasets for the European marginal seas have been published and used to compute regional high resolution climatologies. External datasets, the World Ocean Database from NOAA and the CORA dataset from the Copernicus Marine Service in situ Thematic Assembly Center, have been integrated with SDC data collections to maximize data coverage and minimize the mapping error. The products are available through the SDC catalogue accompanied by Product Information Documents containing the specifications about product’s generation, characteristics and usability. Digital Object Identifiers are assigned to products and relative documentation to foster transparency of the production chain, acknowledging all actors involved from data providers to information producers.
