This two-day workshop is to develop a comprehensive, integrated, interdisciplinary approach to observing, understanding and modeling ice-shelf-buttressed, marine-based glacier systems that drain major ice sheets. Such systems have the ability to evolve rapidly (years to decades) in response to ocean-induced ice-shelf loss, with consequences for rapid rise of global sea level and potentially huge impacts on society. Three components are required to understand the potential significance of these systems: simultaneous comprehensive measurements of all physical elements (atmosphere, ocean, ice shelf, glacier, sea ice, sea/glacier bed); paleo history of the study region(s) from late glacial times through the Holocene to present, to assess relative stability and potential rates of change; and comprehensive modeling incorporating principal physical processes including the ability to represent system variability through the Holocene in relation to climate reconstructions and into the future in response to projected climate change.The workshop will assemble bring representatives of the above three disciplines to identify key elements required to make transformative progress on understanding processes that control the sensitivity of these systems to change. Invitees include researchers with skills in in situ and remote-sensing observations of all elements of the target systems including existing structure of ocean and ice-shelf systems as well as reconstructions of past oceans and climate, and numerical modelers with interests ranging from regional ocean circulation and ice-shelf and glacier processes to paleo-history of large ice sheets. International invitees include researchers with capabilities and skills that augment US resources.Discussions at the workshop will be centered on (1) identification of essential components of a comprehensive study, and (2) development of a logistically manageable interdisciplinary strategy that could be applied to study one or more systems determined to be representative of similar systems in both Greenland and Antarctica.Broader impacts: The workshop will document a strategy for making transformative advances in understanding the potential for large and rapid sea level rise from ocean-induced retreat of marine-based glaciers and ice streams presently buttressed by ice shelves. The specific goals of the proposed workshop will stress the urgency of interdisciplinary collaborations between glaciologists, oceanographers, paleo-scientists, modelers, and technology developers. Likely attendees include early-career polar researchers and underrepresented groups. Proposed meeting dates are adjacent to major national meetings, and students will be encouraged to attend to experience the process of developing major research initiatives.

这个为期两天的研讨会将制定一个全面的，综合的，跨学科的方法来观察，理解和建模冰架支撑，海洋冰川系统，排水主要冰盖。这种系统有能力迅速演变（数年至数十年），以应对海洋引起的冰架损失，造成全球海平面迅速上升，并可能对社会产生巨大影响。了解这些系统的潜在意义需要三个组成部分：所有物理要素的同时综合测量（大气、海洋、冰架、冰川、海冰、海/冰川床）;研究区域从晚冰期到全新世到现在的古历史，以评估相对稳定性和潜在变化率;和综合模拟，包括主要的物理过程，包括代表系统变化的能力，通过全新世与气候重建和未来的预测气候变化的反应。研讨会将汇集来自上述三个学科，以确定关键要素，需要取得变革性进展的理解过程，控制这些系统的变化的敏感性。受邀者包括具备对目标系统的所有要素进行现场和遥感观测技能的研究人员，包括海洋和冰架系统的现有结构以及过去海洋和气候的重建，以及感兴趣的数值模拟人员，其兴趣范围从区域海洋环流和冰架和冰川过程到大型冰盖的古历史。国际受邀者包括具有丰富美国资源的能力和技能的研究人员。研讨会的讨论将集中在（1）确定综合研究的基本组成部分，以及（2）制定一个后勤管理的跨学科战略，该战略可应用于研究一个或多个被确定为格陵兰岛和南极洲类似系统代表的系统。研讨会将记录一项战略，以取得变革性进展，了解海洋引起的海洋冰川和目前由冰架支撑的冰流退缩可能导致海平面大幅度快速上升。拟议的研讨会的具体目标将强调冰川学家，海洋学家，古科学家，建模者和技术开发人员之间的跨学科合作的紧迫性。可能的与会者包括早期职业极地研究人员和代表性不足的群体。拟议的会议日期毗邻主要的国家会议，并鼓励学生参加体验发展重大研究举措的过程。
