We assessed the anthropogenic impacts on southwestern Australian submarine canyons by quantifying macro-litter discovered during Remotely Operated Vehicle surveys. The study area encompasses the Bremer canyon systems and Perth Canyon. The categories of macro-litter identified by our study are plastic, metal, aluminium, glass, fabric, mixed, derelict fishing gear, and unclassified. The anthropogenic impacts in the canyons explored is minimal, especially in the Bremer canyon systems, whereas Perth Canyon has comparatively more macro-litter, presumably due to intense maritime traffic and nearby urban development. On a global scale, however, the environmental status of southwestern Australian canyons is relatively pristine. This analysis provides a baseline for the monitoring and enduring stewardship of these habitats where lush and diverse biota, including deep-sea corals, thrive.
我们通过量化在遥控潜水器调查中发现的大型垃圾来评估人为因素对澳大利亚西南部海底峡谷的影响。研究区域包括布雷默峡谷系统和珀斯峡谷。我们研究中确定的大型垃圾类别有塑料、金属、铝、玻璃、织物、混合、废弃渔具和未分类。探测到的峡谷中的人为影响很小，特别是在布雷默峡谷系统中，而珀斯峡谷中的大型垃圾则相对较多，可能是由于海上交通繁忙和附近城市发展所致。然而，就全球范围而言，澳大利亚西南部峡谷的环境状况相对原始。这项分析为这些栖息地的监测和长期管理提供了一个基线，这些栖息地拥有丰富多样的生物，包括深海珊瑚。
