10月13-15日，有机碳循环和生物地球化学国际研讨会（International Workshop on Organic Carbon Cycle and Biogeochemistry in Marginal Seas）在中国海洋大学成功举行。
本次研讨会由中国海洋大学赵美训教授、王旭晨教授、美国佛罗里达大学Thomas S. Bianchi教授和瑞士联邦理工学院Timothy I. Eglinton教授共同组织发起，由国家自然科学基金创新研究群体项目“海洋有机生物地球化学（41221004）”、高等学校学科创新引智计划“海洋化学”创新引智基地（B13030）与海洋化学理论与工程技术教育部重点实验室、青岛海洋科学与技术国家实验室共同资助。会议邀请了来自德国亥姆霍兹中心极地与海洋研究所的Ruediger Stein教授、美国华盛顿大学的Julian Sachs教授、纽约州立大学石溪分校Cindy Lee教授、美国欧道明大学David Burdige教授、厦门大学戴民汉教授、同济大学张传伦教授和中科院植物所冯晓娟研究员等来自不同国家的20余位专家和学者。中国海洋大学校长于志刚教授出席会议并致欢迎词，国家自然科学基金委地球科学部任建国处长、中科院广州地化所彭平安院士作为特邀嘉宾出席。创新研究群体项目组、海化重点实验室和国内其他单位百余名师生参加了研讨会。
此次研讨会聚焦河口与边缘海有机碳循环和生物地球化学，在为期三天的会期内，海内外学者就河流物质输送、河口和近岸过程、边缘海生物地球化学循环、沉积过程和历史记录、边缘海与大洋物质交换和开放大洋过程等前沿方向的最新进展和未来发展趋势展开了热烈交流和讨论，并就未来加强合作达成了基本共识。本次研讨会对海化重点实验室学科方向进一步凝练、若干国家级在研项目的执行都起到了巨大的推动作用。与会青年教师和研究生也纷纷表示，与这些学术大师的近距离接触不但使他们拓宽了视野，也使他们感受和体悟到了科研的魅力，激励他们从新的角度思考和解决问题。
