Publisher National Institute of Polar Research 10-3, Midori-cho, Tachikawa-shi, Tokyo 190-8518, Japan Editors Kazuyuki Saito Mamoru Ishikawa Preface The second Asian Conference on Permafrost (ACOP 2017) was convened at Hokkaido University, Sapporo, Japan, July 2-6. The conference organizers and co-sponsors were the Arctic Research Center, Hokkaido University, Japanese Society of Snow and Ice, Tokyo Geographical Society, Sapporo Convention Center, Kajima Co., Shimizu Co., Meiwafosis Co., LI-COR, Chemical Grouting Co., Seiken Co., Cubic-I Co., Campbell Scientific, Climate and Cryosphere (CliC), Arctic Challenge for Sustainability (ArCS), and the International Permafrost Association (IPA). A total of 180 participants from 18 countries including accompanying persons attended: Austria (1), Canada (7), China (62), Denmark (1), France (4), Germany (5), Hong Kong (2), Indonesia (1), Japan (55), Mongolia (6), Norway (18), Portugal (2), Republic of Korea (2), Russia (23), Slovenia (1), Switzerland (2), and the USA (6). The ACOP 2017 LOC provided travel grants to 20 persons including young researchers and keynote speakers. The sessions covered all aspects of frozen ground research, from needle ice to deep permafrost, from frozen ground engineering in cities to permafrost on volcanoes, and from links between frozen ground and ancient cultures to present-day outreach. The daily sessions started with plenary talks from senior and young keynote speakers: Tazio Strozzi (Switzerland), Norikazu Matsuoka (Japan), Kabir Rasouli (Canada), Arne Instanes (Norway), Hisao Izuta (Japan), Sonia Tomaskovicova (Denmark), Anna Liljedahl (USA), and Jens Strauss (Germany). A total of 86 oral and 55 poster submissions were presented in a series of two concurrent sessions. In the first day of the conference, a joint workshop between the IPA’s Mapping Initiative and GlobPermafrost took place to discuss current conditions and future collaboration on permafrost mapping and remote sensing. On the same day, Arctic adventurer Yasunaga Ogita and Professor Emeritus at Hokkaido University, Masami Fukuda, kindly provided general lectures to the public at the museum of Hokkaido University. The abstracts submitted to the conference were compiled, and distributed in a USB memory to the participants at the registration. After the conference, however, we received a number of enquiries from those who could not attend the conference, asking for publication of the ACOP2017 abstracts in a more accessible and citable form. The local organizing committee of the ACOP2017 decided, following internal discussions, that we should publish with a doi. Finally, total of 141 abstracts were published in this Book of Abstracts, ACOP2017. - Kazuyuki Saito and Mamoru Ishikawa, 2020.
