Umweltbewertung von Abgasreinigungsanlagen zur Schwefelminderungen auf Seeschiffen; Schwerpunkt: Analyse des Scrubber-Waschwassers und Aktualisierung der Grenzwerte der Scrubber-Richtlinie (MEPC.259(68)) - ImpEx

Ziel des Vorhabens ist es, den internationalen Verhandlungsprozess für die Regelung des Abwassers aus Abgasreinigungsanlagen zur Schwefelminderung auf Seeschiffen (Scrubbern) mit den im Rahmen des Projektes erarbeiteten wissenschaftlichen Ergebnissen unter Berücksichtigung der Belange des Meeresumweltschutzes zu unterstützen und dadurch zur Versachlichung der Diskussion in den Gremien beizutragen. Um weitere Erkenntnisse über die Menge und Zusammensetzung des Abwassers zu erlangen, ist eine Probenahmekampagne auf mehreren Schiffen geplant. Die Wasserproben werden im Labor analysiert, u.a. auf Schadstoffe, wie Schwermetalle und PAKs. Darüber hinaus werden die Wasserproben ökotoxikologisch untersucht. Whole Effluent Toxicity (WET) Tests und spezifische Toxizitätsstudien werden durchgeführt, um die Auswirkungen der Einleitungen auf die Meeresumwelt besser bewerten zu können. Weitere Fragestellungen im Projekt sind die Bewertung der Online-Messsysteme an Bord und die Verbesserung des Probenahme-Protokolls. Die Ergebnisse werden kontinuierlich in die Gremien auf EU- (ESSF) und internationaler Ebene (IMO) eingespeist.

REHEATFUNQ: A Python package for the inference of regional aggregate heat flow distributions and heat flow anomalies

The REHEATFUNQ Python package helps to work with the (residual) scatter of surface heat flow even in small regions. REHEATFUNQ uses a stochastic model for regional aggregate heat flow distributions (RAHFD), that is, the collected set of heat flow measurements within a region marginalized to the heat flow dimension. The stochastic model is used in a Bayesian analysis that (1) yields a posterior estimate of the RAHFD which captures the range of heat flow within the analysis region, and (2) quantifies the magnitude of a surface heat flow anomaly within the region, for instance through the generating frictional power. The stochastic model underlying REHEATFUNQ views heat flow data, uniformly sampled across the region of interest, as a random variable. A gamma distribution is used as a model for this random variable and information from the global data set of Lucazeau (2019) is introduced by means of a conjugate prior (Miller, 1980). The detailed science behind the model is described in Ziebarth et al. (202X). The analysis by Ziebarth et al. (202X) can be reproduced through the Jupyter notebooks contained in the subdirectory “jupyter/REHEATFUNQ/”. The location specified in the map below covers the region to which REHEAFUNQ is applied in this analysis. REHEATFUNQ is a Python package that uses a compiled Cython/C++ backend. Compiling REHEATFUNQ requires the Meson build system and a number of scientific libraries and Python packages (and their dependencies) that are listed in the documentation. A Docker image “reheatfunq” is provided as an alternative means of installation. The Docker image comes in two flavors, specified in “Dockerfile” and “Dockerfile-stable”. The former is based on the current “python:slim” image and downloads further dependencies through the Debian package manager, leading to a short image generation time. The latter bootstraps the REHEATFUNQ dependencies from source, aiming to create a reproducible model. To do so, “Dockerfile-stable” depends on the sources contained in “vendor-1.3.3.tar.xz”. If you plan to build the stable image, download both “REHEATFUNQ-1.3.3.tar.gz” and “vendor-1.3.3.tar.xz”, and see the README contained in the latter. Later versions of the “REHEATFUNQ” archive are compatible with the latest “vendor” archive. A quickstart introduction and the API documentation can be found in the linked documentation.

Felt reports collected by the European-Mediterranean Seismological Centre (EMSC) and aftershocks distribution for a selection of 36 global earthquakes between 2014 and 2020

The European-Mediterranean Seismological Centre (EMSC) is a non-profit scientific organization aiming at establishing and operating a rapid earthquake detection system globally and in particular in the European and Mediterranean regions as well as facilitating exchange between seismological institutes. The EMSC has been a pioneer in citizen seismology by collecting in-situ information on the earthquake impact directly from the witnesses. The EMSC has been collecting citizen intensity felt reports at a global scale for many years via two channels: its websites and its “LastQuake” smartphone application. These felt reports are collected through a set of 12 cartoons representing the 12 levels of the European Macroseismic Scale (Grünthal, 1998). They provide rapid information on how the earthquake’s impact is felt by the local population. The EMSC felt reports were shown to be consistent with the USGS Did You Feel It? (Wald et al., 2011) responses and with manually derived macroseismic datasets (Bossu et al., 2017). Such felt reports are provided for a set of 36 earthquakes, each tagged with a unique ID number. They are only considered for intensity values of up to 10, since higher values are unrealistic. Additionally, an interactive map of the aftershocks distribution is provided for each earthquake. These aftershocks are selected from the EMSC catalogue in the 14 days after the event and within 500km of the epicentre location. On each map, the beachball representing the two nodal planes as given by the Global Centroid Moment Tensor catalogue (Dziewonski et al., 1981; Ekstrom et al., 2012) is displayed at the epicentre location. For each event (identified by unique id number), the first line indicates catalogue information on the earthquake (event_id, region, origin_time (UTC), latitude, longitude, depth, magnitude, strike angle from GCMT) Each following line is a felt report gathered by the EMSC including, the longitude, latitude, reported intensity and report time.

Erstellung eines EU-weiten Überblicks zu Bodenschutzpolitiken (SoCo)

Im Rahmen der EU-Studie mit dem Titel Nachhaltige Landwirtschaft und Bodenschutz (Soco) wird die Beziehung zwischen Bodenschutz-Praktiken und deren ökologische Auswirkungen, die Akzeptanz durch die Landwirte und die Angemessenheit der Maßnahmen auf der Grundlage einer Reihe von Fallstudien untersucht. Dieses Teilprojekt unterstützt die Gesamtstudie, indem sie den Status des Bodenschutzes in allen 27 EU-Ländern durch die Klassifizierung von politischen Maßnahmen auf der Basis eines soliden methodischen Rahmens untersucht. Das Projekt-Team verfolgt für die Recherche einen methodischen Ansatz, die in erster Linie auf der Grundlage einer kombinierten Telefon-und Online-Umfrage unter den Experten in den beteiligten Ministerien und Behörden basiert. Informationen über mögliche Experten in der nationalen Verwaltungen werden über bereits bestehenden Netze (ESSC, SCAPE) gesammelt. Die Online-Erfassung und Speicherung der eingehenden Daten auf einem gesicherten Server-basierte Datenbank-System ermöglicht die effiziente Verwaltung der Ergebnisse und eine bessere Präsentation in standardisierter Form einschließlich Länder-Fiches und Überblickstabellen.

FP4-ENV 2C, A rapid warning system for earthquakes in the european-mediterranean region

Objective: The project aims at improving the procedure currently in operation at the European-Mediterranean Seismological Centre for rapidly locating significant earthquakes in the European-Mediterranean area, analysing their source mechanism, and providing this information to the relevant European authorities and the scientific community in a timely manner. General Information: To enhance the geographical coverage of short-period seismological stations transferring data in quasi-real-time by adding five new networks (Canary Islands, The Netherlands, United Kingdom, Bulgaria and Romania) to the 16 European networks which already send their data to the EMSC in case of a large earthquake. To increase the number of seismological centres locating earthquakes in quasi-real-time. Automatic location software will be implemented at seismological centres in Edinburgh and Thessaloniki. This will improve the capacity of the EMSC to be alerted rapidly in case of a major earthquake and it will allow the EMSC to lower the threshold for triggering the alert system to magnitude 5.0 (it is currently set at 5.5). To carry out studies for defining a better propagation model for the European-Mediterranean region in order to enhance the accuracy of the location computed. This will be achieved by building regional propagation tables and by integrating automatic depth evaluation using a regional discretization of the European-Mediterranean area. To integrate the automatic computation of the scalar seismic moment and Mm magnitude. This magnitude will then be used as a reference magnitude in the alert messages disseminated to the users. To define and implement the appropriate software for fast moment tensor inversion of regional seismic events. To reduce the delay in computing the full moment tensor, automatic phase picking will be applied. Furthermore, the number of broad-band seismic stations contributing their data in real-time will be increased: one station in Spain, two in the Netherlands, one in the United Kingdom and two long-period stations in France will be made available. The main deliverable of this research project will consist of information messages sent out routinely and freely to all interested users following large earthquakes (magnitude greater than 5.0) occurring in the European-Mediterranean area. Within one hour, a first message will provide basic information on the earthquake location and magnitude. A second message will then give the complete description of the source mechanism of the event. Prime Contractor: Centre Sismologique Euro-Mediterraneen; Strasbourg; France.
