International standard for marine surveys proposed by China has been officially published and promulgated by the International Standard Organization
The international standard ISO 23040:2021, “Marine environment impact assessment (MEIA) — Specification for marine sediments in seabed areas — Survey of interstitial biota”, which was jointly proposed by the Institute of Oceanology, Chinese Academy of Sciences and the First Institute of Oceanology, Ministry of Natural Resources, has been officially published and implemented by the International Standard Organization (ISO) on December 10, 2021. It is the first ISO international standard in the field of Marine surveys developed by China and jointly formulated by eight countries, marking an important breakthrough in the internationalization of China's Marine survey technical standards. The project leaders of ISO 23040:2021 are Prof. Yanli Lei and Prof. Tiegang Li.
The international standard ISO 23040 has been officially published and implemented by the International Standard Organization (ISO)
This international standard provides requirements and recommendations for conducting marine surveys of interstitial biota in marine sediments. It includes the specification of technical methods for the investigation of marine sediments, foraminifera, ostracoda, radiolaria, diatoms, coccoliths, sedimentary sporopollen, benthic viruses, benthic microbes (including bacteria, archaea and fungi), benthic microalgae, benthic protozoa and metazoan meiobenthos. This international standard is applicable to marine surveys in diverse benthic habitats at any seabed, such as benthic sediments of coastal zones, shallow seas, or deep-sea waters. This international standard provides relevant technical approaches for the investigation of sediment interstitial biota in seabed areas.
This international standard embodies the recent developments of modern marine science and technology to facilitate international cooperation. It is applicable to investigations and evaluations of marine sediment biodiversity in seabed areas, favoring the development and utilization of marine biological resources, the comprehensive environmental exploration, ecological environment assessment, protection and management, etc. The specifications in this document incorporate technical advances and technological key points, reflecting current state-of-the-art and international practice. The international standards will provide technical support and standard guarantee for multilateral cooperation in the field of Marine survey, build a friendly bridge for international cooperation, and provide a scientific basis for international negotiations and contracting mining activities in seabed areas.
According to the "United Nations Convention on the Law of the Sea" (UNCLOS), the international seabed area refers to the seabed and ocean floor and its subsoil outside the sea area under national jurisdiction, accounting for about 40% of the earth's surface area. In addition, the ongoing negotiation of an international agreement on the conservation and sustainable use of "Biodiversity Beyond National Jurisdiction (BBNJ)" in the seas beyond the scope of national jurisdiction by the United Nations is the most important international legislative process in the marine field. The main topics surrounding the BBNJ, including the area management and environmental impact assessment of international high seas protected areas, require conclusions based on the investigation of sediments and organisms in the seabed area. In addition, many large-scale international comprehensive research programs have been carried out in the seabed area, such as the Ocean Drilling Program (ODP) and the International Ocean Discovery Program (IODP). But so far, due to the lack of international standards, various countries have used different procedures and techniques in the biological survey of seabed sediment gaps, which has created obstacles to data comparison and results calibration in international cooperation. In addition, it also affects the consistency of the scientific assessment of the biodiversity of the seabed area and the environmental assessment resulting from contracting operations.
In 2017, in the absence of an ISO standard in the field of marine surveys, China proposed a New Proposal (NP) for this international standard, which was approved by the ISO project, and received positive responses from relevant countries in the world, such as the United States, the United Kingdom, Russia, Germany, Iran, South Korea, Singapore and Panama appointed experts to participate in the formulation of this international standard. The Working group Draft (WD) was adopted in May 2019, the Committee Draft stage (CD) was adopted at the International Standards Conference in September 2019, and the inquiry Draft International Standard stage (DIS) international ballot was adopted in October 2020. It lasted for four years. ISO 23040：2021 is officially published and promulgated by ISO.
