Sea ice plays a critical role in polar ecosystems and in regional and global climate. Sea ice moderates the exchange of carbon dioxide and other gases between the atmosphere and ocean, supports global ocean circulation through salt drainage, acts as an insulator between the warm ocean and cold atmosphere, and plays a key role in polar food webs. Sea ice remains understudied despite its significance due to the difficulty of accessing and analyzing sea ice samples. The sea ice environment is dynamic and presents numerous hazards that require considerable expertise to mitigate; also, because ice is a solid, samples often require more complex preparation for biological and chemical measurements than for seawater. These challenges may be considerable barriers for new investigators, who typically learn how to overcome them through one-on-one training by a mentor, supervisor, and advisor. This award supports travel for US PhD students and postdoctoral researchers to attend an international sea ice field school hosted by the SCAR expert group Biogeochemical Exchange Processes at Sea Ice Interfaces (BEPSII) and SCOR working group Essential Climate Variables in Ice (ECVice). The field school is taking place at the Canadian High Arctic Research Station, a state-of-the-art field station located in Cambridge Bay, Nunavut, Canada. Students at the school receive comprehensive training in field and laboratory best from international and local experts in sea ice physics, biogeochemistry, ecology, and operations, which will help broaden participation within the sea ice community and encourage new investigators to undertake sea ice studies. Sea ice plays a key role in Arctic and Antarctic biogeochemical cycles. The physical nature of sea ice presents challenges to safe and effective study that serve as a considerable barrier for new investigators. Typically, knowledge of how to safely operate on sea ice, design experiments, and make biogeochemical measurements is transmitted vertically from a mentor, supervisor, or thesis advisor to a student or postdoc. While effective, this compartmentalizes knowledge and excludes new investigators with different expertise, perspectives, and backgrounds from sea ice biogeochemical studies. To broaden participation within the sea ice biogeochemistry community and encourage new investigators to undertake sea ice studies the Biogeochemical Exchange Processes at Sea Ice Interfaces (BEPSII) SCAR expert group and SCOR working group Essential Climate Variables in Ice (ECVice) is hosting an international field school at the Canadian High Arctic Research Station Campus in Cambridge Bay, Nunavut, Canada in May of 2022. The field school brings together international and local (Iqaluktuurmiut) experts in sea ice physics, biogeochemistry, ecology, and operations to provide a comprehensive training program for early career scientists. The school combines classroom and practical sessions and cover topics including snow and ice sampling, the sea ice carbon cycle, gas flux measurements and theory, nutrient cycles, primary and bacterial production, and biogeochemical modeling.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.

海冰在极地生态系统以及区域和全球气候中起着至关重要的作用。海冰缓和了大气和海洋之间的二氧化碳和其他气体的交换，通过盐排水支撑全球海洋循环，充当温暖的海洋和寒冷大气之间的绝缘体，并在极地食品网中起关键作用。尽管很难获取和分析海冰样品，但海冰仍然被忽略了。海冰环境具有动态性，并带来了许多需要大量专业知识来减轻的危害；另外，由于冰是固体，因此与海水相比，样品通常需要更复杂的生物学和化学测量准备。对于新调查人员来说，这些挑战可能是相当大的障碍，他们通常学习如何通过导师，主管和顾问一对一培训来克服他们。该奖项为美国博士学生和博士后研究人员提供了旅行，以参加由Scar Expert Group生物地球化学交换过程（BEPSII）（BEPSII）（BEPSII）和SCOR工作组基本气候变量（ECVICE）主持的国际海冰野外学校。该野外学校将在加拿大北北北极研究站进行，位于加拿大努纳武特的剑桥湾。学校的学生接受了海冰物理学，生物地球化学，生态学和运营的国际和本地专家的野外和实验室的全面培训，这将有助于扩大海冰界的参与，并鼓励新的研究人员进行海冰研究。 海冰在北极和南极生物地球化学周期中起着关键作用。海冰的物理性质给安全有效的研究带来了挑战，这是新研究人员的相当障碍。通常，了解如何在海冰上安全操作，设计实验和进行生物地球化学测量的知识是从导师，主管或论文顾问垂直传输到学生或博士后的。虽然有效，但这将知识划分，并排除了海冰生物地球化学研究中具有不同专业知识，观点和背景不同的新研究人员。为了扩大海冰生物地球化学社区的参与并鼓励新研究人员进行海冰研究，海冰界面的生物地球化学交换过程（BEPSII）疤痕专家小组和SCOR工作组中的ICE（ECVICE）的基本气候变量（EXVICE）在加拿大高级研究站的国际野外校园内举行了国际野外竞选220的国际野外学校，诺纳夫（Cambbridge Bay），加拿大竞技场，加拿大五月内纳纳夫（Cambridge Bay）。 （Iqaluktuurmiut）海冰物理学，生物地球化学，生态学和运营专家，为早期职业科学家提供全面的培训计划。该学校结合了课堂和实践会议，并涵盖了主题，包括雪和冰采样，海冰碳循环，气通量测量和理论，养分周期，主要和细菌的生产以及生物地球化学建模。这项奖项反映了NSF的法定任务，并通过评估了基础的Merit和Broadia and Broadia and Broadia and Broadia and Intellia and Suppliation and Broadia and Supportion。
