VECTOR seismic array in the Irish Midlands

A network of 210 continuously running, digital seismic stations equipped with short-period sensors (200 stations) and broadband sensors (10 stations) was deployed in an area of ~8 x ~6 km in the Irish Midlands (north of Collinstown) for a time period of ~6 weeks. The network was part of the EU project VECTOR (https://vectorproject.eu) aiming to investigate – among others – possible solutions for least invasive forms of exploration for mineral resources. In this context the collected data was mainly used to derive a 3D model of the subsurface (seismic shear wave velocity) using ambient noise tomography (down to ~1.5km depth). We thank all field crews for their excellent work rendered to the project. Waveform data is available from the GEOFON data centre, under network code 7W.

Upward mantle flow from novel seismic observations (UPFLOW)

The goal of the UPFLOW project is to develop new high-resolution seismic imaging approaches along with new data collection, and to use them to constrain upward flow in unprecedented detail. We conducted a large off-shore experiment in the Azores-Madeira-Canary Islands region, which is a unique natural laboratory with multiple upwellings that are poorly understood in general. UPFLOW deployed and recovered 49 ocean bottom seismometers (OBSs) in a ~1,000×2,000 km2 area in the Azores-Madeira-Canary Islands region starting in July 2021 for ~13 months, with an average spacing of ~150-200 km. The seismic deployment and recovery involved institutions from five different countries: Portugal (IPMA, IDL, Univ. of Lisbon, ISEL), Ireland (DIAS), UK (UCL), Spain (ROA) and Germany (Potsdam University, GFZ, Geomar, AWI). 32 OBSs were rented from the DEPAS international pool of instruments maintained by the Alfred Wegener Institute (Bremerhaven), Germany, while other institutions borrowed additional instruments (7 from DIAS, 4 from IDL, 3 from ROA, 4 from GEOMAR). Most of the instruments have three-component wideband seismic sensors, but three different designs of OBS frames were used. Waveform data is available from the GEOFON data centre, under network code 8J, embargoed data may be accessible upon request. We want to acknowledge the exceptional support of the whole team of able seaman, steward, cooks, engineers, mechanicians, electricians and motorman assistants of the vessel RRV Mário Ruivo. With special Thanks to José Ângelo Gomes (Captain), Luís Ramos (Superintendent), Mafalda Carapuço Vessel’s manager (IPMA), Henrique Ferreira Land logistics (IPMA), Celine Ahmed and Jen Amery (Administrative support at UCL)

Roman cements for architectural restoration to new high standards (ROCARE)

Objective: Highly hydraulic binders, known as natural or Roman cements, were key materials to cover façades of buildings of the European Historicism and Art Nouveau (19th/early 20th century), a period of rapid urban growth in Europe. The maintenance, restoration and reconstruction of historic Roman cement façades form therefore an important issue in Europe s efforts to preserve its architectural heritage. Therefore, the ROCARE project is proposed to provide conditions for the industrial development and commercialisation of Roman cements which is an innovative, promising technology developed at the level of a pilot-scale prototype in the recent research project of the 5th Framework Programme ROCEM, 2003-2006. The increasing awareness of the conservation profession and their interest in the product call now for further actions encompassed by the proposed ROCARE-project, which aim at filling gaps in knowledge and reducing the entry barriers of the novel technology to the market. They include: - scaling up of the RC technology to a competitive level by optimising the process technologies at various conditions of production - laboratory tests and studies to fully understand cement hydration and property development, as well as optimum conditions of mortar processing and handling in the conservation practice - broad dissemination measures to enlarge the market potential of the technology. The proposed project is designed for three-year duration and will be jointly conducted by 15 partners from industry, SMEs and research centres in 7 countries. It will allow the prototype developed in the earlier project to establish itself on the European market of building construction.

Etude de methodes d'entretien de zones protegees propres a restaurer et entretenir leur valeur naturelle (FRA)

Pour assurer une gestion des zones protegees qui conserve les valeurs naturelles originales, il faut souvent maintenir une pression qui freine l'evolution vers le climax. Cette operation, toujours delicate, demande la mise en oeuvre de moyens complexes, mais qui doivent rester pratiquement realisables et financierement supportables pour les organismes publics ou prives qui se chargent de cette tache. Fauchage, decapage superficiel, interventions diverses sont evalues dans cette etude situee dans la region genevoise. (FRA)

Erosion am Suedufer des Neuenburgersees

Studie zur Untersuchung der Ufererosion am Suedufer des Neuenburgersees zwischen Yverdon und Estavayer. Betroffen ist vor allem das Naturschutzgebiet von Champ-Pittet. Jedes Jahr werden ein bis zwei Meter Ufer oder ein bis zwei ha des Ufergebietes von den Wellen abgetragen. Neben den Wellen ist die Seespiegelabsenkung der 1. Juragewaesserkorrektion um 3m die wichtigste Ursache.

Aufbau eines Langfrist-Basisprogramms zur Beobachtung der natuerlichen Entwicklung im Schweiz. Nationalpark

Sukzessive sollen die bestehenden Dauerbeobachtungen im Nationalpark ergaenzt und untereinander koordiniert werden. Als Ziel wird ein mit vertretbarem Aufwand durchfuehrbares Basis-Beobachtungsprogramm angestrebt. Dieses soll - langfristige Umweltveraenderungen aufzeigen, - relevante Einfluesse (Huftiere, Tourismus, Klima etc.) erfassen, - als Grundlage fuer die Parkverwaltung dienen (Management, Planung von Eingriffen, Information), - den Nationalpark als Referenzgebiet darstellen.

Mindestbedarf von naturnahen Ausgleichsflaechen in landwirtschaftlichen Gunstlagen des Alpenrheintales

Der Inhalt der Forschungsfrage lautet: Wieviel Natuerlichkeit braucht die Landschaft? Dies soll an konkreten Fallbeispielen untersucht werden. Ziel des Projektes ist der Versuch der Formulierung angemessener Aussagen ueber die Notwendigkeit von verschiedenen naturnahen Landschaftselementen und Mindestflaechen, sowie deren Verteilung in typischen Lagen des Alpenrheintals. Es sind, wenn moeglich, Folgerungen fuer die Ausstattung landwirtschaftlich intensiv genutzter Lagen zu ziehen.

Nutzungsgeschichte des Nationalparks

Zusammentragen aller verfuegbaren Daten ueber die verschiedenen Nutzungsarten ab ca. 1200 (Mittelalter) im Raum des spaeteren Nationalparkes (Gemeinden Zernez; Scuol/ Muenstertal). Heutige Flaeche: 168 km2 Heutige Nutzung: Natur-Reservat (keine weiteren Eingriffe des Menschen) Umweltbezug: Veraenderungen der Lebensraeume durch den Menschen, spaetere Entwicklung der Natur ueberlassen.
