本报告概述了深海采矿（DSM）活动产生的水下噪声排放及其对海洋生物的潜在影响的最新知识。报告还总结了水下噪声的现有法律和政策框架，包括其在该地区DSM活动管理方面的缺陷。最后，本文就填补知识空白的必要步骤提出了建议，并为DSM活动产生的噪音的决策奠定了坚实的基础。
人为水下噪声被科学界和许多国际组织视为对海洋生物的主要威胁。有确凿证据表明，与DSM活动相关的船舶和主动声勘探（如声纳和地震勘测）的噪声排放对海洋物种具有重大有害影响。此外，提取（疏浚、钻探、刮除）、采矿工具定位（声纳）、泵（立管系统）和潜水器、ROV和AUV（例如推进装置）会发出巨大的噪音，可能对海洋物种造成潜在的重大有害影响。
This report gives an overview of the current knowledge on underwater noise emissions from Deep-Sea Mining (DSM) activities and their potential impacts on marine life. The report also summarises existing legal and policy frameworks on underwater noise including their shortcomings with respect to management of DSM activities in the Area. It concludes with recommendations on the necessary steps to fill knowledge gaps and create a solid basis for decisionmaking regarding noise from DSM activities.
Anthropogenic underwater noise is recognized by science and a wide range of international organizations as a major threat to marine life. There is solid evidence that noise emissions from vessels and active acoustic exploration (e.g. sonar and seismic surveys), which are relevant to DSM activities, have significant harmful effects on marine species. In addition, extraction (dredging, drilling, scraping), mining tool positioning (sonar), pumps (riser system), and submersibles, ROVs and AUVs (e.g. propulsion), can emit loud noise which may result in potentially significant harmful effects on marine species.
