AtlantECO podcast

In this episode of the AtlantECO podcast, we had the privilege of speaking with Ferenc Jordan, an expert in network analysis, who shared insights into the importance of this methodology in studying the ocean. Although Ferenc hails from Hungary, a landlocked country, his fascination with the sea began in childhood, inspired by the documentaries of David Attenborough and Jacques Cousteau. His journey in marine science and ecology led him to explore the fascinating world of network analysis, an essential tool for understanding marine ecosystems.Network analysis is a method of studying systems made up of interacting elements. These interactions can occur between species in an ecosystem, animals in a group, or even individuals in a society. By analysing the structure of these interactions, we can uncover valuable insights that would be missed by focusing on individual elements in isolation.Ferenc explains that in the context of the AtlantECO project, network analysis plays a critical role in studying the microbiome—the trillions of microorganisms that live in marine environments. These microbes, though invisible to the naked eye, form incredibly complex networks, interacting with each other in ways that are not yet fully understood. By mapping these relationships, scientists aim to uncover how different microbes work together or avoid each other, helping to unlock the ecological processes that govern the ocean.Studying the microbial networks in the ocean presents unique challenges. Unlike the traditional food webs of animals, where we can directly observe predator-prey relationships, microbial networks are harder to interpret. Microbes can coexist or avoid each other without any clear sign of direct interaction. The data collected in the AtlantECO project shows how these microorganisms occur together in certain patterns, but the meaning behind these patterns—whether it indicates cooperation or competition for example—remains unclear.Ferenc describes the process of creating smaller, more manageable networks from large, complex microbial datasets. Aggregating these networks to identify "key" microbes—those that play a crucial role in maintaining the stability of the community—can provide valuable insights into the overall health of marine ecosystems. This is a topic of ongoing research in AtlantECO, and the results will likely shed light on new ways to monitor and manage ocean health.One of the key goals of network analysis in the AtlantECO project is to develop indicators that can help communicate the health of marine ecosystems to decision-makers and stakeholders. Just as GDP is a simple indicator of a country's economic health, network-based indicators could signal the well-being of marine environments. These indicators would provide a clear, easily understandable metric that could inform policy decisions and guide the sustainable management of ocean resources.Ferenc also shared his passion for science communication, particularly with younger audiences. As a scientist, he believes it is crucial to make complex research accessible and relatable to the next generation. His goal is not just to contribute to scientific understanding but also to inspire young people to engage with environmental issues and become advocates for the planet's future.More on AtlantECO: www.atlanteco.eu  The AtlantECO project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 862923.

Diving into Ocean Dynamics: A Conversation with Bruno Buongiorno NardelliIn this episode of the AtlantECO podcast, we got the chance to sit down with Bruno Buongiorno  Nardelli, a researcher based in Italy, who has spent over two decades studying the impact of ocean dynamics on climate and marine ecosystems. Join us as we unravel the complexities of his work, understand its significance, and explore what the future holds.Bruno's research focuses on understanding how various oceanic variables contribute to climate change and the behavior of marine ecosystems. Initially, his scientific education centered around geophysical fluid dynamics and remote sensing. Combining these areas, he has developed techniques utilising statistical analysis, physical models, and artificial intelligence to interpret observations and improve our knowledge of the earth’s systems.One core aspect of his research involves collecting and analyzing data from both remote sensing technologies and in situ observations. This approach allows scientists to develop more accurate predictive models and forecasts by understanding underlying processes more thoroughly. He stresses the importance of continuous observation to grasp these complex dynamics, as surface-level data alone cannot provide the full picture.Within the AtlantECO project, Bruno's efforts are directed towards analysing data to understand phytoplankton abundance through ocean color satellite data and separating natural oceanic oscillations from those induced by anthropogenic activities. Such work is vital not just for determining the ocean’s current state but also for predicting future impacts on marine ecosystems and validating climatic models.Bruno mentions that his work extends to shaping future satellite missions for the European Space Agency. These missions aim to improve our observational capabilities, especially concerning the air-sea interface dynamics. Another significant aspect is understanding how mesoscale turbulence helps transport carbon vertically within the ocean—a critical component of the global carbon cycle.Bruno acknowledges that scientific investigation is a never-ending journey. The continuous cycle of discovery and inquiry is central to advancing our understanding of ocean dynamics and their broader implications. Once AtlantECO ends, the data and insights generated will serve as a foundation for future research and projects.The ultimate goal is to provide robust data and sophisticated tools that will enable policymakers to make informed decisions regarding oceanic and environmental stewardship. Thus, Bruno and his colleagues' work is deeply intertwined with the broader mission of sustaining and protecting ocean health in this era of rapid climate change.More on AtlantECO: www.atlanteco.eu  The AtlantECO project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 862923.

In this episode, we delve into the fascinating world of bioprospecting with Tonje Heggeset and Giang-Son Nguyen from SINTEF, a renowned research organisation in Norway. In conversation with Tonje and Giang-Son, we uncover the essence of bioprospecting, its applications, and its significance within the AtlantECO project. First, we ask… what is bioprospecting? Bioprospecting involves exploring various natural sources like plants, animals, and microorganisms for commercially valuable substances such as medicinal drugs, biochemicals, and other materials. In the context of the project, the focus is on microorganisms, including bacteria and fungi, discovered in environments rich in biodiversity. These microorganisms can potentially yield new antibiotics, anti-cancer compounds, and industrial enzymes, contributing to significant advancements in medicine and industry.We then transition into the methodologies of bioprospecting. Our guests explain that there are two primary approaches: functional screening and genome/metagenome sequencing. Functional screening involves searching for specific activities in nature, such as antibiotics. On the other hand, genome sequencing entails identifying genes and predicting their functions using bioinformatics tools.Within the AtlantECO project, SINTEF is in charge of molecular bioprospecting, focusing on discovering new enzymes relevant to stakeholders. This involves data mining from various sources, functional screening, and creating a database of genetic markers for biological sensors. The aim is to provide valuable enzyme candidates for diagnostics, molecular research, and other applications, contributing to the blue economy.More on AtlantECO: www.atlanteco.eu  The AtlantECO project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 862923.

In the latest episode of the AtlantECO podcast, we delve into one of our case studies, which aims to apply the knowledge and resources developed in the project to existing challenges in shallow sea diamond mining. Our guest, Natasha Karenyi, sheds light on the considerations necessary for developing and implementing environmental regulations of coastal areas.Natasha, a marine biologist and lecturer at the University of Cape Town (UCT), shares her journey toward studying and researching marine biology. With a childhood curiosity sparked by high school biology classes and a love for swimming, Natasha's passion for the ocean led her to specialise in benthic ecology and pursue a PhD at the Nelson Mandela University.In our case study, we focus on two countries, Namibia and South Africa, both of which have keen interests in diamond and phosphate mining, as well as petroleum extraction. However, these countries have different policy frameworks, data limitations, and understandings of their marine systems. Natasha highlights the specific challenges and needs within each country and the importance of addressing them to develop effective environmental regulations.Supporting Policy Making through AtlantECO: to address these challenges, AtlantECO implements various strategies. In Namibia, they collaborate with the Namibian Ministry of Fisheries and Marine Resources and Debmarine Namibia to provide baseline benthic information for informed policy decisions. In South Africa, they work with the Department of Mineral Resources to develop guidelines for environmental management of ocean mining.Through research and collaborative efforts, Natasha and her team have identified several challenges that hinder effective environmental impact assessments (EIAs) and marine spatial planning (MSP) processes. These challenges include the lack of consideration for cumulative and indirect impacts, insufficient inclusion of social and economic aspects, and limited access to information; these aspects were all included in the recommendations made recently. As we progress, we aim to further support the different stakeholders in their endeavour to develop EIA processes, streamline reporting standards across sectors, and enhance the integration of social and economic considerations.More on AtlantECO: www.atlanteco.eu  The AtlantECO project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 862923.

In the latest episode of the AtlantECO Podcast, we delve into the critical topic of mega heatwaves in the Atlantic withguest Thomas Frölicher. The conversation covers the causes, consequences, monitoring, and future expectations of theseincreasingly observed phenomena, including the recent heatwave observed in the North Atlantic.Thomas Frölicher, originally from landlocked Switzerland, shares his unique journey into oceanography. Growing up with a curious mind inspired by his father's interest in physics, Thomas eventually found his passion for environmental science. His focus on atmospheric physics led him to explore oceanography during his PhD, where he investigated the variations in oceanic oxygen concentration and its connection to human-caused global warming.We then discuss marine heatwaves, defined as periods of persistently warm ocean temperatures. Thomas explains that these events are becoming more prevalent globally, affecting ecosystems, weather patterns, and land conditions. The North Atlantic, in particular, is experiencing mega heatwaves, with temperatures significantly higher than ever recorded. Thomas discusses potential causes of marine heatwaves, such as enhanced air-sea heat uptake, changing ocean currents, and various other factors. The global ocean currently faces record-high temperatures, with about 30% experiencing a marine heatwave. The North Atlantic stands out with temperatures 0.5 degrees higher than previous records, raising concerns among scientists.To understand these heat waves, scientists rely on high-temporal-resolution datasets from satellites, ARGO floats, buoys, and ocean models. Thomas emphasises the importance of collaboration among researchers with diverse expertise to comprehensively analyse the multitude of factors contributing to the current temperature anomalies. We then touch upon the consequences of mega heat waves on marine life and ecosystems, and Thomas highlights the sensitivity of ecosystems to high temperatures, leading to damages worth billions of dollars in industries such as fisheries and tourism. In AtlantECO project, Thomas and his team aim to assess the impact of a combination of multiple extreme events in the Atlantic, providing valuable data for managing ocean resources and mitigating risks.More on AtlantECO: www.atlanteco.eu  The AtlantECO project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 862923.
