Simplifying quality control and standardization of CTD data under SeaDataNet requirements

Sharing marine data through SeaDataNet infrastructure ensures preservation and promotes reusability. Submission of data to this infrastructure demands a set of technical tasks that cover quality control processing, adoption of common vocabularies, implement fle format standards and preparation of associated metadata. Although common software tools are made available to Data Centres and/or End Users to facilitate data and metadata preparation, these tasks continuous to be complex and time-consuming. To speed-up this process, a Python-Flask web application is presented here to quality check and create metadata and data according to SeaDataNet requirements. The web tool focuses on CTD vertical profles, although code could be easily adapted to process other type of records.Peer Reviewe

Promoting FAIRness in marine data at Centro Nacional Instituto Español de Oceanografía

The Spanish Institute of Oceanography is responsible, among other aspects, for scientifc and technical advice for the Government’s fsheries 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 well as by its diferent typology. The purpose of both the National Oceanographic Data Center and the GIS team is to safeguard data and to disclose what data exists and where, how and when it has been acquired and, in addition, to provide access to that data through the collaboration with diferent international data infrastructures like EMODnet or SeaDataNet. To this end, the data and metadata are subjected to quality control and formatted for integration into a national Spatial Data Infrastructure (SDI). This SDI has a GeoNetwork catalogue with ~ 1750 oceanographic campaigns, together with (meta)data and services that are continuously being revised and incorporated. All this with the ultimate goal of making the data increasingly FAIR.Peer Reviewe

POLYBIUS2020, a cost-effective underwater autonomous video system to record fishing gear selectivity performance catching fish and marine litter

Underwater video cameras are a highly versatile survey solution for marine fsheries research. The POLYBIUS2020 is a system specially designed to be used as a tool for video recording inside towed fshing gears. Its design allows for rapid installation onboard commercial fshing vessels as well as for quick reconfguration and battery replacement. The system is based on simple commercial components to ensure low costs and the opportunity of future studies using house technology. The feld experiments carried out have shown the fexibility and ability of the system to obtain key information about fshing selectivity, fora and fauna characterization and marine litter presence.Peer Reviewe
