<p>The transportable Quantum Gravimeter QG-1 is designed to determine the local gravity to the nm/s² level of uncertainty. It relies on the interferometric interrogation of magnetically collimated Bose-Einstein condensates in a transportable setup consisting of a sensor head and an electronics supply unit.<br>In this contibution we introduce the measurement concept and discuss it's impact on the measurement uncertainty. We are reporting on the first gravity data taken with the device over the course of three days thereby validating the operability and the measurement concept applied in QG-1.<br>We acknowledge financial support from "Niedersachsisches Vorab" through "Förderung von Wissenschaft und Technik in Forschung und Lehre" for the initial funding of research in the new DLR-SI Institute.

The papers in this volume were presented at the eleventh meeting of the Austronesian Formal Linguistics Association (AFLA 11), held from April 23-25 at the Zentrum für Allgemeine Sprachwissenschaft, Berlin, Germany. The conference was organized by Hans-Martin Gärtner, Joachim Sabel, and myself, as part of the research project Clause Structure and Adjuncts in Austronesian Languages. We gratefully acknowledge the financial support by the German Research Foundation (Deutsche Forschungsgemeinschaft). We would like to thank Wayan Arka, Agibail Cohn, Laura Downing, Silke Hamann, S J Hannahs, Ray Harlow, Nikolaus Himmelmann, Yuchua E. Hsiao, Lillian Huang, Ed Keenan, Glyne Piggott, Charles Randriamasimanana, Joszef Szakos, Barbara Stiebels, Jane Tang, Lisa Travis, Noami Tsukido, Sam Wang, Elizabeth Zeitoun, Kie Ross Zuraw, and Marzena Zygis for reviewing the abstracts. We are thankful to Mechthild Bernhard, Jenny Ehrhardt, Fabienne Fritzsche, Theódóra Torfadóttir and Tue Trinh for their help during the conference. I would like to thank Theódóra for providing essential editorial assistance.
