Digital Twins of the Ocean (DTO) are a rapidly emerging topic that has attracted significant interest from scientists in recent years. The initiative, strongly driven by the EU, aims to create a digital replica of the ocean to better understand and manage marine environments. The Iliad project, funded under the EU Green Deal call, is developing a framework to support multiple interoperable DTO using a federated systems-of-systems approach across various fields of applications and ocean areas, called pilots. This paper presents the results of a Water Quality DTO pilot located in the Trondheim fjord in Norway. This paper details the building blocks of DTO, specific to this environmental monitoring pilot. A crucial aspect of any DTO is data, which can be sourced internally, externally, or through a hybrid approach utilizing both. To realistically twin ocean processes, the Water Quality pilot acquires data from both surface and benthic observatories, as well as from mobile sensor platforms for on-demand data collection. Data ingested into an InfluxDB are made available to users via an API or an interface for interacting with the DTO and setting up alerts or events to support ’what-if’ scenarios. Grafana, an interactive visualization application, is used to visualize and interact with not only time-series data but also more complex data such as video streams, maps, and embedded applications. An additional visualization approach leverages game technology based on Unity and Cesium, utilizing their advanced rendering capabilities and physical computations to integrate and dynamically render real-time data from the pilot and diverse sources. This paper includes two case studies that illustrate the use of particle sensors to detect microplastics and monitor algae blooms in the fjord. Numerical models for particle fate and transport, OpenDrift and DREAM, are used to forecast the evolution of these events, simulating the distribution of observed plankton and microplastics during the forecasting period.
Background: Nurses and nursing students experienced an emotional burden while working during the COVID-19 outbreak. During the COVID-19 outbreak three questions for nurses working under these extreme circumstances were formulated: 1. What today’s events do you remember? 2. How do you feel (physically and mentally)? 3. Do you have enough support? The purpose of this study was to obtain insight into whether nurses and nursing students perceive that the use of the three-questions-method contributes to effective coping with the emotional burden during the COVID-19 outbreak. Methods: Focus group interviews were held with hospital nurses (n = 11) and nursing students with internships in mental health care (n = 2), hospital (n = 9), and homecare/nursing home care (n = 3) in September 2020 followed by twenty semi-structured interviews one year later. Results: Almost all nurses and nursing students named factors that contributed to the emotional burden: fear, powerlessness, frustration, lack of knowledge about COVID-19, and pressure to pass the internship. Participants indicated that using the three-questions-method can help to effectively cope with the emotional burden during and after the COVID-19 outbreak. Conclusions: Using the three-questions-method offers added value in coping with emotional burden and can be used in education as well as in practice.
