Evaluierung der historischen Daten der deutschen Larvensurveys im Hauptlaichgebiet des Herings der westlichen Ostsee

The results of the time series of larvae surveys in the main spawning area of the western Baltic Sea spring spawning herring were evaluated. The quality of the recruitment index N 30 was studied. The raw data of 1977 to 1987 have got lost. In 1988 and 1989 the data for the estimation of the recruitment index are biased. Only since 1990 the basic data can be considered reliable

Tensed Muscles

In 2019 Steffi Klenz was selected as one of the artists to undertake the Camden Alive Commission. Camden Alive is part of the Mayor’s London Borough of Culture and is a Mayor’s Cultural Impact Award winner. In 1971 Camden Council acquired 22 acres of land, just off York Way, London from the National Freight Corporation and built the Maiden Lane Estate. 200 years ago the site was farmland, with ‘Midden Lane’ running through it. This route into London from the north became notorious for highwaymen and footpads until the Midland Railway took over the area and used it as a depot for coal, cattle and sheep. The Maiden Lane estate, designed by architects Benson and Forsyth, was a visionary, modernist scheme which included plans for 400 new homes, shops, sports facilities, a community centre, a primary school and open spaces. Due to financial pressures in the late 1970s the plans were not fully realised, resulting in a split site and years of practical and social challenges. During 2019 Steffi Klenz spent time at Maiden Lane talking with residents and immersing herself in the architecture of the space. Her photographic practice has been preoccupied with the built environment, exploring the notion of place and spatiality. Her work unfolds in urban places and buildings but it is not architectural photography; instead it uncovers unexpected narratives and traces of history embedded in the place. Tensed Muscles explores the relationship between the architectural promise of modernist living; of equality and opportunity, and the reality of living in Maiden Lane in the 40 years since its inception. Klenz layers images of the neighbourhood, mixed with architectural plans, archive material and hand-drawn medical illustration to unearth what is hidden beneath the surface of the site. Klenz is interested in the entanglements of the poetic, political and socio-economic aspects of the neighbourhood and uses the metaphor of the ‘phantom limb’ to present this. Medical drawings and images of Maiden Lane residents’ disconnected limbs signify something missing – something missing in society relating to inequality and social-economic trauma, represented through bodily trauma. The use of the body in her work connects us with the site, animating modernist architectural plans which use the body to merely populate the space. Illustrations of tensed, spasmodic muscles suggests that these animated bodies (that society and politics might want to disappear) become visible, real and vocal. This idea is apparent in the images of disconnected hands. These hands are separate and disconnected from the main body politic through trauma, but are presented as significant tools of communication. In hip hop and rap hands become gestural instruments and, as presented in Tensed Muscles, capable of vocalising through sign language by shaping an alphabet. Klenz further explores communication by making correlations between Scriptio Continua (continuous writing), an early style of writing without spaces or punctuation which was performed rather than read and the fast-paced transmission of ideas through rap and hip hop. Klenz’s complex abstract collages of images, photograms, Scriptio Continua, graph work and line drawing disrupt the discipline of architecture as a measured, rational and ordered space; interrupting this with human agency, interaction and the realities of life on a London estate. First iteration of project: a music album which is available on Spotify for free and also on the 7th March 2020 Brownsilla and Boss B with a string quartet performed the album live in front of Klenz's large projection piece. There will also be a solo exhibition at the Camden Arts Centre and an Augmented reality app designed by Arcade. In the Spring of 2019 Maiden Lane rap artists Brownsilla and Boss B collaborated with photographic artist Steffi Klenz. As artists in residence at the Camden Local Studies and Archives Centre, they explored the histories of Maiden Lane, using maps, newspapers, court reports and images. Weaving these stories with their own experiences of living and being in London, the artists reflect on what has been, and of its relevance to lives today. The resulting album presents a complex view of Maiden Lane, one of tension and frustration but also of confidence and optimism

Das deutsche Larvenprogramm im Hauptlaichgebiet des Herings der westlichen Ostsee - eine Forschungsaufgabe von internationaler Bedeutung

The German larvae surveys in the main spawning area of the herring of the western Baltic Sea - an international important program. The article gives an overview over the German herring larvae surveys in the Greifswalder Bodden and Strelasund. This program is performed under ecological points of view annually in the main spawning area of the herring of the western Baltic Sea and delivers indices, which are well suited as independent estimates of the herring year-class strength

Schwacher Nachwuchsjahrgang 2001 des Herings in der westlichen Ostsee

Several fishery independent estimates of the year-class strength are necessary for the assessment and the management of the total fish stock. An index for the year-class strength of the spring spawning herring in the western Baltic Sea is estimated on the basis of larvae surveys in the most important spawning ground. The results indicate a weak year-class 2001

Guter Nachwuchsjahrgang 2004 des Herings der westlichen Ostsee, des Kattegats und Skagerraks (ICES-Gebiete IIIa und 22 – 24)

Several fishery independent estimates of the year-class strength are necessary for the assessment and the ma-nagement of the total fish stock. An index for the year-class strength of the spring spawning herring in the western Baltic Sea is estimated on the basis of larvae surveys in the most important spawning ground. The results indicate a good year-class 2004

Ichthyoplanktonaufnahmen als Beitrag zu Biodiversitätsuntersuchungen in der westlichen Ostsee

Ichthyoplankton material provides information on the species composition in an area of investigation and leads to a better understanding of the entire fish community. Since 1993 every year in May and/or June an ichthyoplankton survey in ICES-Subdivision 22 and 24 has been performed to sample the plankton community of fishery resources in the western Baltic Sea. One objective was to get signs of possible changes in the natural structures of this fish community. The time series derived from the Bongo-Net samples does not show a clear trend in larval densities. Values varied, but up to now samplings in the western Baltic Sea yielded only low mean densities. According to the kind of reproductive biology the fish species were divided in three major groups: • Fish species with a long developmental phase in the plankton community • Small short living species with benthic eggs and a reduced plankton phase • Guests without local spawning populations. Species could be identified, which were absent in the fish larvae catches of the western Baltic Sea in the 60s and 70s

Staffages

8 individual images: digital C-Type prints framed in oak frames with glass (each individual image sized differently). The artist selects, collages and photographs objects from the Tunbridge Wells Museum collection to form new arrangements and associations. Severed from their previous context in the collection, the objects chosen become ‘new originals’ in non-hierarchical compositions in which objects of local importance or quotidian matter are accorded the same status as objects of historical and economic value. The degree of flexibility and portability of the collection is translated in Klenz’ experimental usage of the plinth. Klenz is interested in the traditional role of the plinth as isolating the object from its surrounding, having the authoritarian ability to take the object away from its collection. Klenz is interested to transform the traditional plinth into an abstract sculpture that refers us to the utopian visions of Constructivist Vladimir Tatlin’s sculptures, El Lissitzky’s posters and paintings and Kazimir Malevich ‘Architectons’ of the second and third decades of the 20th Century

A Survey of Past and Present Principles of Dealing with Desertion in the Four Major Non-Lutheran Protestant Church Bodies in America

The question then arose as to what church bodies have said in an official way to guide and direct their ministers in handling each individual case on its own grounds . This then became the center of attention for this thesis. To limit the scope of the thesis, concern was narrowed to the principles of treatment as found in the recognized confessions and creeds of the four major, non-Lutheran, Protestant denominations in America

Maglehøj – preservation of birch bark in a passage grave with evidence of forced entry in prehistory

Maglehøj is a Danish passage grave which has birch bark incorporated into its construction. An account of the opening of the monument in 1823 reports the discovery of an earth-free chamber and describes constructional details, including the use of birch bark. An investigation undertaken in 1997, prompted by the information given in this account, revealed that the birch bark was relatively well preserved and that there had been a break-in through one gable of the chamber later in prehistory. This article gives several examples of similar intrusions, which were a more common phenomenon than previously appreciated. The results of a 12-month investigation of the climatic conditions inside Maglehøj’s chamber, aimed at optimising preservation of the birch bark, are also presented. The investigation included measurements of air change and humidity carried out under different conditions. The outcome was a recommendation that the entrance to the chamber be closed with an air-tight seal
