CCS – was ist das? // Folge 10 – In der Nordsee: CCS, Lärm und Schweinswale

from CCS – was ist das? · host CCS – was ist das?

In dieser Episode sprechen wir mit Tim Taugnitz vom Deutschen Meeresmuseum in Stralsund, der uns Einblicke in die Auswirkungen von Unterwasserlärm auf Schweinswale gibt. Tim erklärt, wie die Meeressäuger akustische Signale nutzen, um sich in ihrer Umgebung zu orientieren, und warum sie besonders empfindlich auf menschliche Lärmquellen wie Schiffsverkehr, Bauarbeiten für Windkraftanlagen oder auch seismische Untersuchungen für eine mögliche CO2-Speicherung im tiefen Meeresuntergrund reagieren. Wir diskutieren, wie der Bau von Anlagen im Meer umweltverträglicher gestaltet werden kann, beispielsweise durch den Einsatz von Blasenschleiern, und welche Herausforderungen und Fortschritte es bei der Lärmminderung gibt. Zudem werfen wir einen Blick auf die Methoden der Forschung und den aktuellen Wissensstand zur langfristigen Wirkung von Lärm auf Schweinswalpopulationen. 2:38 - Wie erforscht man Schweinswale?  8:02 - Regelmäßigkeit der Untersuchungen 9:35 - Welche Herausforderungen gibt es bei der Nutzung von Hydrophonen? 11:18 - Wie kann man sich ein Hydrophon vorstellen?  14:25 - Wie geht es Schweinwalen in der Nordsee? 15:42 - Was gibt es für typische Lärmquellen in der Nordsee? 21:19 - Verhält sich Lärm unter Wasser anders als in der Luft? 23:58 - Wie wirkt sich Lärm auf Schweinswale aus? 28:36 - Wie funktionieren Blasenschleier und wie effektiv sind sie? 34:09 - Welcher Lärm entsteht bei CCS-Voruntersuchungen und ließe sich der Lärm reduzieren? 43:29 - Lässt sich der hohe Frequenzbereich der Airguns optimieren, um den Schweinswalen weniger zu schaden? 46:17 - Wie gut ist der Effekt von Lärm auf Schweinswale bereits erforscht und welche Lücken gibt es noch? 47:29 - Wie sind die Auswirkungen der Ausfahrten langfristig auf die Population? 53:08 - Wie läuft eine Untersuchung ab? 1:06:48 - Gibt es in anderen Ländern schon Schutzvorgaben für Schweinswale? 1:15:58 - Lärmmanagement unter der Nordsee #CCS, #podcast , #klimaschutz Moderation: Kristin Hamann Gesprächspartner: Tim Taugnitz Produktion: Ole Duggen Weitere Informationen unter folgendem Link: https://cdrmare.de/infomaterialien/ Kontakt-Mailadresse: [email protected] Musik: Songtitel & Künstler: “Astrisx”, von Blue Dot Sessions Quelle: Free Music Archive https://creativecommons.org/licenses/by-nc/4.0/

Managing Next Generation Energy Systems Cambridge University Background Stakeholders working with energy systems have to make complex decisions formulated from risk-based assessments about the future. The move towards more renewables in our energy systems complicates matters even further, requiring the development of an integrated power grid and continuous and steady transformation of the UK power system. Network flows must be managed reliably under uncertain demands, uncertain supply, emerging network technologies and possible failures and, further, prices in related markets can be highly volatile. Mathematicians working with engineers and economists, can make significant contributions to address such issues, by helping to develop fit-for-purpose models for next generation energy systems. These interdisciplinary approaches are looking to address a range of associated problems, including modelling, prediction, simulation, control, market and mechanism design and optimisation. This knowledge exchange workshop was part of the four months Res The Data Engineering Show The Firebolt Data Bros The Data Engineering Show is a podcast for data engineering and BI practitioners to go beyond theory. Learn from the biggest influencers in tech about their practical day-to-day data challenges and solutions in a casual and fun setting.SEASON 1 DATA BROSEldad and Boaz Farkash shared the same stuffed toys growing up as well as a big passion for data. After founding Sisense and building it to become a high-growth analytics unicorn, they moved on to their next venture, Firebolt, a leading high-performance cloud data warehouse.SEASON 2 DATA BROSIn season 2 Eldad adopted a brilliant new little brother, and with their shared love for query processing, the connection was immediate. After excelling in his MS, Computer Science degree, Benjamin Wagner joined Firebolt to lead its query processing team and is a rising star in the data space.
