黄岩岛海域具有重要生态价值资源价值科研价值——专家谈《2025年黄岩岛海域生态环境状况调查评估报告》
华南所副所长陆俊卿:2025年8月,华南所等单位在2024年首次对黄岩岛开展摸底调查的基础上,再次 联合开展黄岩岛海域生态环境状况的系统调查。与去年首次调查相比,今年的调查工作可以总结为"三 个更加注重"。 一是更加注重系统性与针对性。在调查对象和内容上,除了去年调查的海水水质、沉积物质量、生物质 量、海洋垃圾、珊瑚礁生态系统等各类生态环境要素外,针对黄岩岛自然生态系统和物种多样性,今年 新增了对黄岩岛潟湖内海草、黄岩岛海域砗磲生态状况的专题调查。在调查点位设置上,在去年调查点 位的基础上,进一步加密黄岩岛潟湖、礁坪和礁坡等点位布设,其中,珊瑚礁生态调查点位比去年增加 了50%,所获取的1740份样品量是去年的2.9倍,为更加系统深入地了解黄岩岛海域生态环境状况提供 了坚实基础。 二是更加注重科学性与先进性。现场调查和综合评估严格遵守国家相关技术标准规范,充分参考借鉴国 际上通用的相关技术方法,通过全过程质量控制确保调查数据科学性可靠性。同时,采用先进技术手 段,通过潜水调查、水下机器人、无人机航拍等获取了反映黄岩岛海域生态环境状况的大量影像资料, 在《报告》配套的视频中可以看到不少我们在现场拍摄的生动鲜活素 ...
“海洋与气候村”世界巡展走进上海
Core Viewpoint - The "Ocean and Climate Village" world tour exhibition aims to enhance public understanding of the ocean's critical role in regulating the Earth's climate system, aligning with the United Nations' goals for sustainable ocean development [3]. Group 1: Event Overview - The exhibition is held in Shanghai from October 10 to 19, co-hosted by UNESCO's Intergovernmental Oceanographic Commission and Prada Group [3]. - The event features various components, including a technology exhibition, photography exhibition, documentary screening, thematic discussions, and educational workshops [3]. - The exhibition is free to the public and has attracted over 12,000 visitors [3]. Group 2: Key Themes - The exhibition focuses on critical themes such as marine biodiversity, climate change, ocean acidification, sea level rise, and the impact of human activities on the ocean [3]. - It aims to achieve the seventh expected outcome of the UN's "Ocean Decade," which is to create an inspiring and attractive ocean [3]. Group 3: Expert Engagement - Experts from the Ocean Institute participated in discussions on "Ocean Literacy and Global Consensus," engaging with the public on topics related to ocean science, climate change, and public education [4].

Core Insights - An international research team led by researcher Chen Jitao from the Nanjing Institute of Geology and Palaeontology has published findings on the impact of global warming under high oxygen environments on oceans in the journal Proceedings of the National Academy of Sciences (PNAS) [1] Group 1: Research Context - The late Paleozoic glaciation period, lasting from 360 to 260 million years ago, is noted as the longest icehouse climate period since the establishment of terrestrial higher plants and ecosystems [4] - During this period, atmospheric oxygen levels peaked at approximately 1.2 to 1.7 times the current levels, potentially linked to the gigantism of marine and terrestrial animals and triggering significant marine biodiversity events [4] Group 2: Research Findings - The research team studied carbonate rock sediment sequences from 310 to 290 million years ago in the Guizhou Luodian Basin, exploring global carbon cycles and marine redox states during this period [5] - The findings indicate that increased organic carbon burial in the ocean may have led to a decrease in atmospheric CO2 and an increase in oxygen levels, despite high overall oxidation levels [5] - Intermittent massive carbon emissions during this time could cause repeated climate warming and hypoxia in the oceans, expanding the area of oceanic hypoxia to between 4% and 12%, potentially leading to stagnation or decline in marine biodiversity [5] Group 3: Implications - The study suggests that under current icehouse climates and high oxidation states, global warming may lead to widespread oceanic hypoxia, providing valuable insights into the interconnections and feedback mechanisms within the Earth's climate system [7]
