    Authors: Scholz, Dieter;

    Die Umweltwirkung eines Verkehrsmittels setzt sich zusammen aus Energieverbrauch, Er-derwärmung, Änderung der lokalen Luftqualität, Lärm und Landschaftsverbrauch. Die Erderwärmung ergibt sich im Verkehrswesen insbesondere durch die Klimawirkung des CO2. Die gesamte Umweltwirkung ergibt sich bei Flugzeugen aus CO2, Stickoxiden (NOx) und durch Wolkenbildung aufgrund von Kondensstreifen. Dies wird mit Hilfe der äquivalenten CO2 zusammengefasst. Statistisch gesehen kann die Umweltwirkung insbesondere durch niedrigeres Fliegen stark verringert werden. Kondensstreifen treten auf, abhängig von der Flughöhe, der Lufttemperatur und der Luftfeuchtigkeit. Langlebig sind die Kondensstreifen nur dann, wenn die relative Luftfeuchtigkeit einen bestimmten Wert überschreitet. Es sind die typischen Passagierflugzeuge mit Strahltriebwerden die Kondensstreifen im Reiseflug verursachen. Nur wenige dieser Kondensstreifen müssten vermieden werden, um die Umweltwirkung deutlich zu reduzieren. Die Erderwärmung durch Passagierjets ist dreimal so hoch, wie durch CO2 allein. Das ist ein erheblicher Umweltnachteil des Flugzeugs gegenüber dem bodengebundenen Verkehr. Die Wahl des Verkehrsmittels kann bereits nach den physikalischen Grundprinzipien geschehen. Das System Rad-Schiene hat hier einen klaren Vorteil. Insbesondere zum schnellen Überwinden der Ozeane sind Flugzeuge aber konkurrenzlos. Vorgestellt werden Möglichkeiten, mit denen Flugreisende ihre Umweltwirkung verringern können. Das "Ecolabel for Aircraft" bewertet Flugzeuge im Vergleich. Verschiedene Buchungstools stehen im Internet zur Verfügung, die auch den CO2-Ausstoß angeben. The environmental impact of a means of transport is made up of energy consumption, global warming, changes in local air quality, noise and landscape consumption. Global warming in the transport sector is mainly due to the climate impact of CO2. The entire environmental impact of aircraft results from CO2, nitrogen oxides (NOx) and cloud formation due to contrails. This is summarized with the help of the equivalent CO2. Statistically speaking, the environmental impact can be greatly reduced, especially by flying lower. Contrails occur depending on altitude, air temperature, and humidity. Contrails are only persistent, if the relative humidity exceeds a certain value. It is the typical passenger aircraft with jet engines that cause contrails in cruise flight. Only a few of these contrails would have to be avoided in order to significantly reduce the environmental impact. Global warming caused by passenger jets is three times as high as CO2 alone. This is a significant environmental disadvantage of the aircraft compared to ground-based traffic. The selection of a means of transport can already be made according to basic physical principles. The wheel-rail system has a clear advantage here. However, aircraft are unrivalled, especially for quickly overcoming the oceans. Ways in which air travelers can reduce their environmental impact are presented. The "Ecolabel for Aircraft" evaluates aircraft in comparison. The "Karman-Gabrielli Diagram" considers also speed in a comparison of modes of transport.

    Authors: Wink, Mike;

    Tämä diplomityö keskittyy merenkulun säännösten toteuttamiseen ja vaihtoehtoihin perinteisillä Wärtsilä W46 -moottoreilla varustetuille aluksille. Tutkimus käsittelee erityisesti näiden alusten kohtaamia haasteita, kun ne pyrkivät täyttämään kansainvälisen merenkulkujärjestön (IMO) asettamat uusimmat päästöohjeet, erityisesti hiilidioksidipäästöjen vähentämiseen liittyvät vaihtoehdot. Tutkimus tehtiin laivanmoottorivalmistajan toimeksiannosta ja keskittyy pääasiassa tuotannon ulkopuolisiin moottoreihin. Tavoitteena oli tarjota kattava analyysi erilaisista toimenpiteistä ja strategioista, joita voidaan käyttää varmistaakseen IMO:n päästöohjeiden noudattaminen. Näiden vaihtoehtojen tutkiminen edistää tehokkaiden ratkaisujen kehittämistä hiilidioksidipäästöjen vähentämiseksi ja hiilidioksidin intensiteetti-indeksin (CII) parantamiseksi merenkulun alalla ja Wärtsilä-moottoreilla varustetuissa laivoissa. Tutkimuksen tutkimusmenetelmiksi valittiin reaaliaikaisen tiedon sekä kokemusten kerääminen aluksilta, joita voitaisiin hyödyntää tutkimuksessa. Tämä osoittautui kuitenkin haastavaksi lopulta. Saadut tiedot olivat hyvin rajallista johtuen heikosta osallistumisesta ja muista ulkopuolisista syistä. Kuitenkin tutkimus saavutti tilan, jossa teknisiä parannuksia pystyttiin todentamaan ja tuomaan arvokasta sekä hyödynnettävää tietoa moottorivalmistajalle. This Master's thesis focuses on the implementation and options of maritime regulations for vessels equipped with conventional Wärtsilä W46 engines. The study specifically addresses the challenges faced by these vessels in meeting the latest emission guidelines set by the International Maritime Organization (IMO), with a particular emphasis on carbon dioxide reduction options. The study was commissioned by a ship engine manufacturer and primarily examines out-of-portfolio engines. Its objective is to provide a comprehensive simplified analysis of the various measures and strategies that can be employed to ensure compliance with the IMO's emission guidelines. By exploring these options, this study aims to contribute to the development of effective solutions for reducing carbon dioxide emissions and improving the carbon intensity index (CII) in the maritime industry and installations with Wärtsilä W46 engines. The research methods for the study were chosen to be the collection and utilization of real-time data and experiences from the vessels which was found challenging in the end. Received data stayed very narrow due to the poor participation of query and other reasons beyond the control. However, the study achieved the state where technical improvements are raised and offers valuable and useful information to engine manufacturer.

    The 9th Data Science Symposium took place from April 4 - 5, 2024. This time it was organized by AWI. Established in 2017, this is part of a joint series of symposia of AWI, GEOMAR and Hereon. It aims at building bridges between science methods, science applications, and infrastructure developments. As in previous years, contributions are collected, including ideas or results from ongoing projects. As an infrastructure provider, we are particularly interested in current trends, current and overarching developments and community activities. HGF project-related information (Helmholtz Incubator, pilots and projects within the framework of the Initiative and Networking Fund (IVF)) are as interesting as current developments in High Performance Computing, O2A, as well as other projects related to PoF IV or Data Science and Data Management.

    The EO4Intertopo project focuses on mapping Normandy's intertidal zones using optical and radar satellite data. The aim is to improve the management and conservation of these crucial ecosystems. Details Intertidal zones, as natural buffers, are essential for coastal protection, but face strong pressure from human activities and environmental challenges such as rising sea levels and intensifying storms. By focusing on Normandy's intertidal zones, the project supports informed decision-making and encourages proactive management practices to ensure the resilience and sustainability of coastal ecosystems. EO4Intertopo includes the comprehensive mapping of the topography and substrate of Normandy's intertidal environments, the identification of morphological changes in relation to current events and the potential effects of climate change, and the generation of products from satellite data to raise awareness and support decision-making. The methodology involves the use of optical and radar satellite data, as well as tidal models and in-situ observations to measure intertidal topography. EO4Intertopo represents a crucial initiative to understand and protect intertidal ecosystems in the face of current and future environmental challenges. More To learn more about the application please explore Space for Climate Observatory website. Website is available in English and French.

    The Arctic climate is a major environmental concern as it is experiencing strong changes. Notably, recent Arctic warming drives rapid sea ice loss making the Arctic increasingly vulnerable. To better anticipate the consequences of this strong Arctic warming, it is crucial to better understand the driving processes responsible for large uncertainties in future climate projections. Interactions at the atmosphere-ocean-sea ice interface require particular attention. In this context, the PolarRES project aims at developing the coupled system MAR (atmosphere) - NEMO (ocean-sea ice) over the Arctic region at high spatial resolution (25 km). Such coupling will enable the climate community to access precise data at large scale. Since this coupling has never been applied to the Arctic, a proper model evaluation is required. Here standalone model simulations are compared against a newly compiled dataset including land station data. We find high correlations between the modeled and observed data. Our evaluation marks an important step in in the ongoing development of coupled models.

Statistisch gesehen kann die Umweltwirkung insbesondere durch niedrigeres Fliegen stark verringert werden. Kondensstreifen treten auf, abhängig von der Flughöhe, der Lufttemperatur und der Luftfeuchtigkeit. Langlebig sind die Kondensstreifen nur dann, wenn die relative Luftfeuchtigkeit einen bestimmten Wert überschreitet. Es sind die typischen Passagierflugzeuge mit Strahltriebwerden die Kondensstreifen im Reiseflug verursachen. Nur wenige dieser Kondensstreifen müssten vermieden werden, um die Umweltwirkung deutlich zu reduzieren. Die Erderwärmung durch Passagierjets ist dreimal so hoch, wie durch CO2 allein. Das ist ein erheblicher Umweltnachteil des Flugzeugs gegenüber dem bodengebundenen Verkehr. Die Wahl des Verkehrsmittels kann bereits nach den physikalischen Grundprinzipien geschehen. Das System Rad-Schiene hat hier einen klaren Vorteil. Insbesondere zum schnellen Überwinden der Ozeane sind Flugzeuge aber konkurrenzlos. Vorgestellt werden Möglichkeiten, mit denen Flugreisende ihre Umweltwirkung verringern können. Das "Ecolabel for Aircraft" bewertet Flugzeuge im Vergleich. Verschiedene Buchungstools stehen im Internet zur Verfügung, die auch den CO2-Ausstoß angeben. The environmental impact of a means of transport is made up of energy consumption, global warming, changes in local air quality, noise and landscape consumption. Global warming in the transport sector is mainly due to the climate impact of CO2. The entire environmental impact of aircraft results from CO2, nitrogen oxides (NOx) and cloud formation due to contrails. This is summarized with the help of the equivalent CO2. Statistically speaking, the environmental impact can be greatly reduced, especially by flying lower. Contrails occur depending on altitude, air temperature, and humidity. Contrails are only persistent, if the relative humidity exceeds a certain value. It is the typical passenger aircraft with jet engines that cause contrails in cruise flight. Only a few of these contrails would have to be avoided in order to significantly reduce the environmental impact. Global warming caused by passenger jets is three times as high as CO2 alone. This is a significant environmental disadvantage of the aircraft compared to ground-based traffic. The selection of a means of transport can already be made according to basic physical principles. The wheel-rail system has a clear advantage here. However, aircraft are unrivalled, especially for quickly overcoming the oceans. Ways in which air travelers can reduce their environmental impact are presented. The "Ecolabel for Aircraft" evaluates aircraft in comparison. The "Karman-Gabrielli Diagram" considers also speed in a comparison of modes of transport.

    Authors: Wink, Mike;

    Tämä diplomityö keskittyy merenkulun säännösten toteuttamiseen ja vaihtoehtoihin perinteisillä Wärtsilä W46 -moottoreilla varustetuille aluksille. Tutkimus käsittelee erityisesti näiden alusten kohtaamia haasteita, kun ne pyrkivät täyttämään kansainvälisen merenkulkujärjestön (IMO) asettamat uusimmat päästöohjeet, erityisesti hiilidioksidipäästöjen vähentämiseen liittyvät vaihtoehdot. Tutkimus tehtiin laivanmoottorivalmistajan toimeksiannosta ja keskittyy pääasiassa tuotannon ulkopuolisiin moottoreihin. Tavoitteena oli tarjota kattava analyysi erilaisista toimenpiteistä ja strategioista, joita voidaan käyttää varmistaakseen IMO:n päästöohjeiden noudattaminen. Näiden vaihtoehtojen tutkiminen edistää tehokkaiden ratkaisujen kehittämistä hiilidioksidipäästöjen vähentämiseksi ja hiilidioksidin intensiteetti-indeksin (CII) parantamiseksi merenkulun alalla ja Wärtsilä-moottoreilla varustetuissa laivoissa. Tutkimuksen tutkimusmenetelmiksi valittiin reaaliaikaisen tiedon sekä kokemusten kerääminen aluksilta, joita voitaisiin hyödyntää tutkimuksessa. Tämä osoittautui kuitenkin haastavaksi lopulta. Saadut tiedot olivat hyvin rajallista johtuen heikosta osallistumisesta ja muista ulkopuolisista syistä. Kuitenkin tutkimus saavutti tilan, jossa teknisiä parannuksia pystyttiin todentamaan ja tuomaan arvokasta sekä hyödynnettävää tietoa moottorivalmistajalle. This Master's thesis focuses on the implementation and options of maritime regulations for vessels equipped with conventional Wärtsilä W46 engines. The study specifically addresses the challenges faced by these vessels in meeting the latest emission guidelines set by the International Maritime Organization (IMO), with a particular emphasis on carbon dioxide reduction options. The study was commissioned by a ship engine manufacturer and primarily examines out-of-portfolio engines. Its objective is to provide a comprehensive simplified analysis of the various measures and strategies that can be employed to ensure compliance with the IMO's emission guidelines. By exploring these options, this study aims to contribute to the development of effective solutions for reducing carbon dioxide emissions and improving the carbon intensity index (CII) in the maritime industry and installations with Wärtsilä W46 engines. The research methods for the study were chosen to be the collection and utilization of real-time data and experiences from the vessels which was found challenging in the end. Received data stayed very narrow due to the poor participation of query and other reasons beyond the control. However, the study achieved the state where technical improvements are raised and offers valuable and useful information to engine manufacturer.

    The 9th Data Science Symposium took place from April 4 - 5, 2024. This time it was organized by AWI. Established in 2017, this is part of a joint series of symposia of AWI, GEOMAR and Hereon. It aims at building bridges between science methods, science applications, and infrastructure developments. As in previous years, contributions are collected, including ideas or results from ongoing projects. As an infrastructure provider, we are particularly interested in current trends, current and overarching developments and community activities. HGF project-related information (Helmholtz Incubator, pilots and projects within the framework of the Initiative and Networking Fund (IVF)) are as interesting as current developments in High Performance Computing, O2A, as well as other projects related to PoF IV or Data Science and Data Management.

    The EO4Intertopo project focuses on mapping Normandy's intertidal zones using optical and radar satellite data. The aim is to improve the management and conservation of these crucial ecosystems. Details Intertidal zones, as natural buffers, are essential for coastal protection, but face strong pressure from human activities and environmental challenges such as rising sea levels and intensifying storms. By focusing on Normandy's intertidal zones, the project supports informed decision-making and encourages proactive management practices to ensure the resilience and sustainability of coastal ecosystems. EO4Intertopo includes the comprehensive mapping of the topography and substrate of Normandy's intertidal environments, the identification of morphological changes in relation to current events and the potential effects of climate change, and the generation of products from satellite data to raise awareness and support decision-making. The methodology involves the use of optical and radar satellite data, as well as tidal models and in-situ observations to measure intertidal topography. EO4Intertopo represents a crucial initiative to understand and protect intertidal ecosystems in the face of current and future environmental challenges. More To learn more about the application please explore Space for Climate Observatory website. Website is available in English and French.
