Suchraumkulisse Moorrenaturierung (LEP 2013)

Für den Freistaat Sachsen liegt eine umfassende Übersicht der Moore und anderer organischer Nassstandorte aus dem Projekt SIMON vor (DITTRICH et al. 2011 https://www.boden.sachsen.de/erstellung-fachkonzept-landesweites-informationssystem-moore-und-organische-nassstandorte-simon-18146.html). Dafür wurden neben Flächen, die der bodenkundlichen Moordefinition (> 30 cm Torf) entsprechen, auch Böden mit flacheren Torfauflagen (aus Bodenkarten, geologischen Karten) und moortypische Feuchtbiotope (moortypische Biotope aus der Selektiven Biotopkartierung, moortypische FFH-Lebensraumtypen, teilweise ohne nachgewiesene Torfauflage) erfasst und die Maximalfläche aus allen verwendeten Kartengrundlagen gebildet. Die Moorflächen Sachsens wurden somit nicht rein bodenkundlich, sondern ökosystemar unter Einschluss der Moorbiotope und torfbildenden Vegetation definiert. Diese Flächen sind als Moorkomplexe zusammengefasst und bilden die Suchraumkulisse für Renaturierungen von Moor- und Nassstandorten. Die Daten stellen die Moorkomplexe differenziert dar wo: a) eine moortypische Vegetation auf einem moortypischen abiotischen Standort kartiert wurde (3700 ha beziehungsweise 8 Prozent der Moorkomplexfläche) dies sind die nach einer ersten groben Abschätzung noch relativ naturnahen Flächen, b) ein moortypischer Standort kartiert ist, aber keine naturnahen moortypischen Biotope (mehr) vorhanden sind (27000 ha beziehungsweise 57,5 Prozent), c) moortypische Biotope oder FFH-LRT kartiert sind, aber in Boden- und geologischen Karten kein moortypischer Standort (16100 ha, 34,5 Prozent) dargestellt ist es handelt sich um Flächen mit nur flacher oder ohne nachgewiesene Torfauflage oder um kleine Flächen.

Processed seismic data of Cruise SO161 SPOC 2001

Within the frame of the comprehensive SPOC project (Subduction Processes off Chile) the SONNE cruises SO161 Leg 2 and 3 have been conducted between October 16th and November 29th, 2001, off central Chile between 28° and 44° S. In that period some 5,300 km were surveyed with multichannel seismic (MCS) reflection, magnetic, gravity, high-resolution bathymetric and echographic methods. In addition, approximately 3,900 km were surveyed with the same spectrum of methods but without MCS. The total number of 2D profiles was 48. Target was the variation of the subduction properties between the convergent oceanic Nazca and continental Southamerica plates and the different conditions that might influence the subduction process as there are: (1) age of the oceanic crust, (2) its structure and composition, (3) its sedimentary cover, (4) its thermal state, (5) the subduction angle and obliquity, and (6) the terrigenous sediment afflux from the continent. Furthermore, special focus was given to the subduction front, the subduction interface, the structure of the slope as well as to the forearc basin structure and history, and the general distribution of gas hydrate indicating bottom simulating reflectors (BSR's). The results are to be compared with previous studies of the Chilean active margin, e.g. CONDOR (SO 101 and 103) and CINCA (SO 104). The SPOC target area was subdivided into three sub-areas A,B and C. One area was chosen for a detailed survey by aid of a narrowly spaced grid and for a close link with a lot of partners. This area is characterized by a distinctly different margin type south of it is assumed. Moreover, the subducting portion of the aseismic Juan Fernandez Ridge is located in that area representing another important target of the survey. Advantageous conditions enabled the survey of an east-west profile south of Chiloé Island, providing a section through the submerged coastal Cordillera into the flooded longitudinal valley. Some results of Leg 2 and 3 are: In all areas A, B and C no subduction bulge (outer high) in the oceanic crust was visible perhaps due to the shortness of the profiles. The sedimentary cover of the oceanic crust is exceptionally thin, and the crustal thickness is generally quite "normal" with around 7 km derived from relatively weak Moho reflections. In area B a so far magnetically unmapped region was filled providing reliable ages of the oceanic crust, and suggesting that the Challenger Fracture Zone abruptly terminates west of the area of investigation. The survey in area C yielded valuable information on the trench morphology. The so far unique MCS profile south of Chiloé island shows a very wide trench and allows to extrapolate the general conditions encountered an area A southward to approximately 44° S. It can be stated that the situation is in sharp contrast to the basin structures detected by industry profiles further north in the Golfo de Corcovado.

Processed seismic data of Cruise BGR86 1986

In the scope of International Geoscientific Programs and in close cooperation with PETRONAS, Malaysia, and in agreement with the Bureau of Mineral Resources (BMR) and the Bureau of Energy Development (BED), Manila, the Federal Institute for Geosciences and Natural Resources (BGR) carried out a geophysical survey on the continental margin off Sabah during the period from 20th July to 10th August, 1986, and in the Northwestern Sulu Sea during the period from 12th August to 28th August, 1986, using the PRAKLA-SEISMOS vessel EXPLORA chartered by the BGR. The research cruise is a continuation of BGR’s marine geoscientific studies in the South China Sea and in the Sulu Sea with the German research vessels VALDIVIA (1977), SONNE (1982/83) and EXPLORA (1984). The previous investigations provided new information regarding the geological and tectonic history of the southern part of the South China Sea in the context of plate tectonics. According to the interpretation of the large amount of geophysical, geological and geochemical data collected by BGR on previous cruises the widely accepted hypotheses of the presence of an ancient subduction zone beneath the Sabah-Palawan Trough has to be revised. The main objective of the EXPLORA cruise was to search for an Oligocene-Early Miocene carbonate platform off Sabah and in the western Sulu Sea. On the continental margin off Sabah 27 lines were surveyed with gravity and multichannel reflection seismics and partly with magnetics, with a total length of 3,126 km. A strong reflector interpreted as reflector BLUE of previous BGR cruises off Palawan was recognizable beneath the Sabah Trough in depth between 4 and 7 sec (TWT). The isochrones of the reflector strike approximately 50°N. The surface of the reflector dips with 2 to 3 degree towards southeast. Toward the north-western part of the Sabah Trough the reflector is disrupted by a basement high. According to the preliminary interpretation of the gravity data, the prominent free-air anomaly associated with the Sabah Trough and adjacent areas has the same shape as the anomaly observed across the Palawan Trough. Therefore it is concluded that the Sabah Trough is underlain by a thinned continental crust.

Where are we going?

More and more people are flying. In 2018 alone, worldwide passenger air traffic will increase by 6.7 percent compared to the previous year. And it continues to grow. This means that the negative effects are also growing. With this brochure, the German Environment Agency (⁠ UBA ⁠) is therefore addressing an important and at the same time very complex issue. How much air traffic is actually necessary? At what cost to humans, the climate and the environment will it be affordable in the future? How can we achieve a change in transport that not only affects aircraft and airports, but also changes in the economy and consumer behavior? Veröffentlicht in Broschüren.

A blind spot in the assessment of POP/PBT/vPvB properties

This paper relates to the assessment of transformation products (i.e. metabolites, degradation or reaction products), which are formed from plant protection products. It addresses a detail in Regulation (EC) No. 1107/2009 which is not in line with other substance regulations for ⁠ REACH ⁠, medicinal products, and biocides. Our concern: Also transformation products can be hazardous substances. Meanwhile, they are not yet covered within the ⁠ POP ⁠/⁠ PBT ⁠/vPvB assessment and the approval criteria for active substances. Our proposal: At least transformation products occurring in a relevant amount should be included in the assessment and the approval criteria in the same way as active substances.

Green Products in Germany 2014

Are green products being substituted for conventional products, or are they simply being used in parallel? Is the same trend being seen across all product segments? Does it apply to the big points of sustainable consumption? This report takes these questions as a point of departure from which to explore market developments in sustainable consumption overall in Germany, away from any isolated reports of growth in specific segments. The English report is the updated and extended edition of the German report “Grüne Produkte in Deutschland 2013: Status Quo und Trends”. Veröffentlicht in Broschüren.

Introduction of a Carbon Border Adjustment Mechanism (CBAM) in the EU

The EU will introduce a carbon border adjustment mechanism (⁠ CBAM ⁠) on October 1, 2023. The main idea is to apply the same carbon price to imported emission-intensive goods as if they had been produced under EU carbon pricing rules (EU ETS). This is intended to prevent the relocation of domestic industry, which has to bear rising ⁠ CO2 ⁠ costs within the EU ETS, to countries without comparable carbon pricing. This would not protect the climate. The factsheet explains the objectives and functioning of the new climate protection instrument. Veröffentlicht in Fact Sheet.

Helicopter-borne Magnetics CASE11

Onshore geological field work combined with an onshore/offshore aeromagnetic survey was carried out during a joint expedition of the German BGR and the Canadian GSC to understand the structural architecture of the North American continental margin. The helicopter-borne magnetic survey of 2008 covered the northern coastal areas of Ellesmere Island and the adjacent marine areas. The survey was conducted with a line separation of 2 km and covered a 40 to 50 km wide swath offshore about parallel to the north coast of Ellesmere Island from Yelverton Bay in the west to Parr Bay east of Cape Columbia, the northernmost point of Canada. Between Yelverton Bay and M'Clintock Inlet, the survey extended about 40 to 50 km inland, which was the prime target area of the CASE 11 geological investigations. This section of mountainous terrain was flown in a “draped” mode to keep the distance to ground at approximately 1500 ft, same as over the offshore areas. During a 4-weeks period in May/June 2008, close to 8000 km of aeromagnetic line data were acquired, covering an area of 12000 km².

Step-by-Step Guide to Sustainable Supply Chain Management

Many smaller and medium-sized companies, like larger companies, are already engaging with social responsibility in their business practices. At the same time, they are being asked to live up to their social reponsibilities when it comes to their supply chains and are motivated to do so, as supply chains are the origin of a large share of environmental impacts. Supply chains also hold great potential for and provide opportunities to avoid or at least decrease considerable risks to the environment, those impacted, and the companies themselves. The catastrophic impact of suppliers’ insufficient security and occupational health and safety standards, as the collapse of the Rana Plaza building in Bangladesh revealed, shows how important and urgent it is for companies to address the social impact of their activities within their supply chains as well.
