Antarctic science--global concerns by Gotthilf Hempel( Book )

13 editions published in 1994 in 3 languages and held by 318 WorldCat member libraries worldwide

Public awareness of the importance of Antarctic research, particularly in relation to global problems, has increased. The book spans a broad spectrum of Antarctic science from the "ozone hole" to microbiology to the sea ice. The main focus is on the role of Antarctica and the Southern Ocean in the world climate system, e.g. the formation of sea ice and its relevance to ocean circulation, the biological pump in relation to CO2 release. The past climate history is revealed by the analysis of ice cores and sediments. Studies of plate tectonics and fossil records reach further back in earth history. Key words in the biological chapters are krill and the rich Antarctic benthos. Finally, the potential conflict between conservationists, researchers and tourists is discussed

Faszination Meeresforschung : ein ökologisches Lesebuch by Gotthilf Hempel( )

7 editions published between 2006 and 2017 in German and held by 220 WorldCat member libraries worldwide

In diesem Buch berichten 95 Wissenschaftlerinnen und Wissenschaftler über ihre Forschung im Ozean und an den Küsten. Sie führen den Leser von den eisbedeckten Polarmeeren über die Nord- und Ostsee bis zu den Seegraswiesen, tropischen Mangroven und Korallenriffen. Die Beiträge veranschaulichen die Vielfalt der Lebensgemeinschaften zwischen Strand und Tiefsee. Das Größenspektrum der Organismen reicht von Walen und Fischen über Planktonkrebse und Muscheln bis zu Kieselalgen und Bakterien. Die globalen – vom Leben im Meer bestimmten – Stoffkreisläufe werden ebenso behandelt wie die molekularbiologischen Anpassungen der Mikroorganismen, und hier sind auch die größten methodischen Fortschritte zu verzeichnen. Zu den spannenden Themen der angewandten Meeresforschung gehören die Überfischung und die nachhaltige Nutzung der Meere, die Gefährdung durch Schad- und Nährstoffeinträge, die Einschleppen fremder Organismen und die Zerstörung von Lebensräumen. Vielfältig und bereits deutlich nachweisbar sind die Einflüsse des globalen Klimawandels auf das Leben im Meer. Forschungsschiffe, Unterwasser-Roboter, Gensonden und Datenbanken, aber auch mathematische Modelle und naturnahe Experimente sind wichtige Werkzeuge der Meeresbiologen. Exkurse über die Geschichte und Struktur der meeresbiologischen Forschung in Deutschland runden die Übersicht ab. In 48 selbständigen Beiträgen fügt sich die Vielfalt moderner, meeresökologischer Forschung zu einem faszinierenden Gesamtbild zusammen. Das Buch richtet sich an Lehrende und Lernende und an alle, die sich für das Meer und seine Bewohner, für modernes Ressourcenmanagement und marinen Naturschutz interessieren
