================================================================ 日本堆積学会 メールマガジン ◆2014年10月10日(587号) ================================================================ Hereby we have the pleasure to inform you about the organization of the session "Revealing palaeoceanographic variability from Contourite Depositional Systems: state-of-the-art and future challenges" during the XIX INQUA Congress, organized from 27 July to 2 August, 2015, in Nagoya, Japan. The title for this congress is “Quaternary Perspectives on Climate Change, Natural Hazards and Civilization”. We kindly invite you to consider submitting an abstract for this session. You can find the abstract of the session below. The call for abstracts and preregistration will open soon and will close on 20 December 2014. You may find more information of this meeting on http://inqua2015.jp or through Facebook https://www.facebook.com/INQUA2015 ABSTRACT of session: Contourite Depositional Systems contain an association of erosional and depositional sedimentary features, which are driven through a complex interaction of bottom currents, pre-existing seabed morphology and sediment supply, reflecting the oceanographic response on the variable atmospheric processes. Although most of the large present-day contourite drifts have been initiated within the Neogene, they all experienced an intensification since the start of the Quaternary, whereas some responded even more vigorously with respect to the Middle Pleistocene Revolution. Both geophysical records as coring and drilling, allow to extract a wealth of palaeoceanographic information from the contourite deposits, enabling to reconstruct the spatially and temporally variable currents pathways, orientation, intensities, as well as all related water-mass properties. During the last decade, improved technologies and a higher awareness of the contourite paradigm has revealed more small-scaled examples along the ocean margins, as well as in shallow water environments and even within lakes. This session aims to further increase the awareness and the (sensitive) palaeoceanographic recording potential of Contourite Depositional Systems in presenting a collection of state-of-the-art case studies from all possible depositional environments and to address the future challenges in this multidisciplinary domain. One of the major challenges include to better understand the dynamic link between various contouritic erosive or depositional features and their driving physical oceanographic processes. Whereas initially this was solely coupled to the deep-water thermo-haline circulation, it has become evident that local bottom current intensification, for example through internal tides or amplification by topographic obstacles, play a larger role than previously expected. Additionally, more reports are being made of an opportunistic feed-back loop between contouritic processes and cold-water coral reefs and mounds. In addressing the above topics, and others, we endeavor to improve the existing set of diagnostic criteria, aiming to fully access to the palaeoceanographic potential locked inside the contouritic log-book. ================================================================ # 不達メールアドレスは随時配信リストより削除します. # メルマガのバックナンバーは堆積学会ホームページからご覧いただけます. ■■■■■■■■■■■■■■■■■■■■■■■■■■■ 日本堆積学会 事務局 〒305-8567 茨城県つくば市東1-1-1中央第七 産業技術総合研究所地質調査総合センター(田村 亨)内 メールアドレス: ホームページURL: http://sediment.jp/ ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
