By creating a dependable, transparent, and cost-effective system for forecasting and ongoing environmental impact monitoring of exploration and exploitation activities in the deep sea, TRIDENT seeks to contribute to the sustainable exploitation of seabed mineral resources. In order to operate autonomously in remote locations under harsh conditions and send real-time data to authorities in charge of granting licenses and providing oversight, this system will create and integrate new technology and innovative solutions. The efficient monitoring and inspection system that will be created will abide by national and international legal frameworks. At the sea surface, mid-water, and the bottom, TRIDENT will identify all pertinent physical, chemical, geological, and biological characteristics that must be monitored. It will also look for data gaps and suggest procedures for addressing them. These are crucial actions to take in order to produce accurate indicators of excellent environmental status, statistically robust environmental baselines, and thresholds for significant impact, allowing for the standardization of methods and tools. In order to monitor environmental parameters on mining and reference areas at representative spatial and temporal scales, the project consortium will thereafter develop and test an integrated system of stationary and mobile observatory platforms outfitted with the most recent automatic sensors and samplers. The system will incorporate high-capacity data processing pipelines able to gather, transmit, process, and display monitoring data in close to real-time to facilitate prompt actions for preventing major harm to the environment. Last but not least, it will offer systemic and technological solutions for predicting probable impacts of applying the developed monitoring and mitigation techniques

The ocean takes up approximately 25% of the carbon dioxide that humans emit to the atmosphere, it absorbs most of the excess heat trapped in the Earth system by greenhouse gas emissions, thus regulating climate and life on Earth, and also provides a remarkable number of resources for humanity. Most geo-hazards occur in oceanic areas. High-quality systematic ocean observations are necessary to improvour knowledge and understanding of the complex environmental processes and to serve as early warning systems of great socio-economic impact. Research Infrastructures (RIs) are large-scale facilities that provide resources and services for scientific communities to conduct high-level research and foster innovation. RIs promote knowledge, outreach and education to public, private, and policy stakeholders, as well as providing crucial information to operational services such as Copernicus. In Europe several marine RIs have been established, which are maintained by national and European Union (EU) resources. This paper describes the significance of the marine RIs in the European Marine Observation Landscape, their status in terms of cooperation, coordination and integration. It highlights the socio-economic benefits for this integration process, being a significant pillar of the European Ocean Observing System (EOOS)

The Norway lobster, Nephrops norvegicus, supports a key European fishery. Stock assessments for this species are mostly based on trawling and UnderWater TeleVision (UWTV) surveys. However, N. norvegicus are burrowing organisms and these survey methods are unable to sample or observe individuals in their burrows. To account for this, UWTV surveys generally assume that “1 burrow system = 1 animal”, due to the territorial behavior of N. norvegicus. Nevertheless, this assumption still requires in-situ validation. Here, we outline how to improve the accuracy of current stock assessments for N. norvegicus with novel ecological monitoring technologies, including: robotic fixed and mobile camera-platforms, telemetry, environmental DNA (eDNA), and Artificial Intelligence (AI). First, we outline the present status and threat for overexploitation in N. norvegicus stocks. Then, we discuss how the burrowing behavior of N. norvegicus biases current stock assessment methods. We propose that state-of-the-art stationary and mobile robotic platforms endowed with innovative sensors and complemented with AI tools could be used to count both animals and burrows systems in-situ, as well as to provide key insights into burrowing behavior. Next, we illustrate how multiparametric monitoring can be incorporated into assessments of physiology and burrowing behavior. Finally, we develop a flowchart for the appropriate treatment of multiparametric biological and environmental data required to improve current stock assessment methods.

At 1440 utc (1540 local time) on Saturday 18 June 2022, when low tide had passed and the tide was due to rise, the water drained from the harbours of Union Hall and nearby Courtmacsherry on the south coast of Ireland (see Figure 1a). Eyewitnesses captured the event on video,1 with observers remarking that it reminded them of reports of the tide receding ahead of the tsunami in Japan in 2011. The event was captured by the Irish Marine Institute’s tide gauge in Union Hall, which recorded a drop in water level of 70cm in 5min. Compared to the normal ebb and flow of tides of ~1cm per minute, this was a dramatic event. The event impacted most of the Irish south coast, from Castletownbere to Dunmore East and onwards to Britain, with reports of unusual tidal behaviour in Pembrokeshire in South Wales (see Sibley, 2022, this issue).
