Collaborative Research: Conference: Priorities for Future US-led Physical Oceanography Fieldwork in the Sub-polar Southern Ocean

南大洋在调节海平面上升和全球气候方面发挥着关键作用。这些地区也是开展持续观测项目最具挑战性的地区之一，因为进入这些地区存在巨大的后勤困难。基于大型国际正在进行的观测工作（如南大洋碳气候观测和建模以及国际思韦茨冰川合作）的成功，迫切需要重新评估和调整未来由美国主导的南大洋物理海洋学研究和观测重点。该项目将举办一个研讨会，讨论未来美国主导的南大洋科学的优先事项，强调可以监测快速演变的海冰覆盖地区和南极边缘的全年观测方法。虽然近年来我们对南大洋动力学的理解取得了实质性进展，但控制热量吸收和碳吸收、海冰变率和冰盖稳定性的局部过程是全球气候模式中最大的不确定性来源。一个关键的缺口是缺乏对南大洋次极地的全年一致观测测量。本次研讨会将促进社区讨论以下问题：(1)维持美国在南极海洋学方面的领导地位的关键科学和后勤需求；(2)有希望的新观测方法将测量扩展到传统上有限的冬季；(3)加强研究界的途径，包括加强传统上代表性不足的群体（包括早期职业研究人员）的参与和提高与国际伙伴的协调水平。该研讨会虽然主要侧重于物理海洋学，但将召集来自南大洋各个分支学科的研究人员，并确保参与反映更广泛的科学界的多样性。讲习班活动和建议的摘要文件将在活动结束后两个月内汇编和散发。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Southern Ocean play a key role in regulating sea level rise and our global climate. These regions are also some of the most challenging to conduct sustained observational programs due to the immense logistical difficulties in accessing them. Building on the success of large international ongoing observations efforts (such as Southern Ocean Carbon Climate Observations and Modelling and the International Thwaites Glacier Collaboration), the need to reassess and align future US-led research and observational priorities for Southern Ocean physical oceanography is pressing. This project will host a workshop to discuss priorities for future US-led Southern Ocean science, emphasizing year-round observational approaches that can monitor the rapidly evolving sea ice-covered regions and Antarctic margins.While there have been substantial advances in our understanding of the Southern Ocean’s dynamics in recent years, local processes that govern the uptake of heat and carbon uptake, sea ice variability, and ice sheet stability are among the greatest sources of uncertainty in global climate models. A critical gap is the lack of consistent year-round observational measurements of the subpolar Southern Ocean. This workshop will facilitate community discussion concerning (1) key scientific and logistic needs to sustain the US’s leadership in Antarctic oceanography; (2) promising new observational approaches that extend measurements into traditionally limited winter periods; (3) ways to strengthen the research community, both by enhancing participation from traditionally underrepresented groups (including early career researchers) and improving the level coordination with international partners. The workshop, while primarily focused on physical oceanography, will convene researchers from various Southern Ocean subdisciplines and ensure participation that reflects the diversity of the broader scientific community. A summary document of the workshop’s activities and recommendations will be compiled and disseminated within two months of the event’s conclusion.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
