自然资源部海洋生态系统动力学重点实验室（海洋生态系统动力学实验室），原国家海洋局海洋生态系统与生物地球化学重点实验室，成立于2005年8月。实验室以自然资源部第二海洋研究所为依托单位，在该所原海洋化学研究室、海洋生物学研究室基础上，整合其它相关优势学科组建而成。

实验室根据自然资源部“两统一”职责部署，结合原有学科基础，目前设置近海生态系统关键过程与健康评估、深海生态系统观测与生境保护、极地生物地球化学过程与气候变化三个研究方向。主要研究内容包括：探索人类活动和环境自然变化对我国陆架边缘海、深海大洋与极地海域C、N、P、Si等生源要素循环的调控机制；开展区域海洋生态系统关键物种的生态和生理特征及其调控机制，大洋上层生态系统与底层生态系统的耦合关系等研究；研发海洋生态环境观测和监测关键技术，发展适用于海上的，快速、方便、准确的新技术、新方法，以及实时监测和自动观测平台，完善相关的现场监测、观测和取样技术体系和标准。

实验室现有固定研究人员78人，其中研究员18名、正高级工程师1名，副研究员26名、高级工程师9名；博导12名、硕导36名。目前在站博士后8人，硕博研究生110人，聘用人员10余人。实验室拥有价值上亿元的内、外业调查和分析测试设备，初步形成了包括海洋实时原位观测、锚系观测、走航观测、拖曳式观测取样、剖面观测在内的生态环境外业观测体系。通过全体实验室成员的努力，目前已在深海和极地生物地球化学过程、大洋生物多样性、近海环境变化与生态效应等方面形成了观测技术研发与科学研究相结合的研究特色。

实验室未来将围绕我国近岸海域生态空间规划、海洋生态修复，以及极地、大洋生态环境国际治理，解决海洋生态环境保护、海洋生物资源可持续利用和海洋治理中的科学和技术问题；瞄准国际前沿，在我国邻近边缘海、极地、大洋的全球变化与生态系统响应研究中取得创新成果。

Key Laboratory of Marine Ecosystem Dynamics, MNR

Key laboratory of Marine Ecosystem Dynamics (MED), MNR was established in August 2005 and merged from the former Marine Chemistry Department and Marine Biology Department, Second Institute of Oceanography (SIO), Ministry of Natural Resources (MNR). The laboratory is one of three key laboratories in SIO, and one of the main basic research lab on marine ecology and environment under Ministry of Natural Resources.

As one of the main forces, the laboratory staff participated in the Sino-US joint investigation and study on process of marine sedimentation in the Changjiang Estuary from 1980 to 1981, the first South Ocean Expedition in China in 1984, the first Chinese Arctic Expedition in 1999 and the Sino-French joint investigation and study on marine biogeochemistry in the Changjiang Estuary from 1985 to 1987, which has strongly promoted the development of marine biogeochemistry studies in Chinese coastal waters and polar seas. Since the 1980s, laboratory staff have also participated in major national investigations and research projects such as the comprehensive survey of coastal zone & marine resources, the comprehensive survey of Chinese island resources, the Sino-Japanese Kuroshio survey, the environmental survey of China's continental shelf economic exclusive zone, China's previous scientific surveys of the north and south poles, the national marine pollution baseline survey, the comprehensive survey and evaluation of China's coastal environment, and the international seabed regional environmental survey and evaluation. Since 1976, the laboratory has led the development and production of more than 40 kinds of standard and references materials for marine environmental monitoring and oceanographic research, such as nutrients and trace metals.

At present, the laboratory is home for 74 permanent researchers, temporary employees and graduate students. The laboratory was equipped more than 150 million RMB facilities for field observation and lab analysis. Field facilities include real-time in-situ ocean observation system, mooring observation system, navigation observation system, towed observation and sampling system, and profile observation system. Laboratory based functional analytical clusters include seawater chemical analysis, organic geochemical analysis, trace element analysis, pollutant analysis, marine biological identification, molecular biology, primary productivity, flow cytometry and laser scanning confocal electron microscope, etc. In the past 10 years, the laboratory has undertaken over 300 projects, including MOST key projects (863, 973 key projects), NSFC key projects, Marine Public Welfare key projects, National Ocean Specific Project and Chinese Specific Projects for Polar Research (CHINARE Project). The laboratory published more than 800 scientific papers, including more than 200 SCI papers. More than 20 invention patents have been obtained, and more than 30 monographs, atlas and essays have been published. It has won 20 scientific research awards at or above the national and provincial levels, of which 3 have won the first prize at the provincial and ministerial levels.

The current laboratory research fields include (1) biogeochemical processes in the Chinese coastal waters and polar seas with specific focus on biological pump and organic carbon burial; (2) ocean biodiversity and benthic food web; (3) coastal environmental changes and ecological responses such as harmful algal bloom, hypoxia and ocean acidification, marine microbial biodiversity and molecular biology.
