Abstract

This paper summarises research on ambient noise data collected during the summers of 2016 and 2017 by an autonomous Ambient Noise Measurement System (ANMS) deployed in the Kongsfjorden, Arctic. The primary goals of this study are to identify the various soundscape components and the variation of the soundscape in the Arctic environment during the summers of 2016 and 2017. This work mainly quantifies the ambient noise sources during each month of the summer. After analysing the data, five distinct sources of soundscape were identified, out of which three geophysical sources, including iceberg bubbling, glacier calving, and rain noise, as well as two anthropogenic sources, such as shipping noise and ice ramming noise, were identified. No biological sources were identified either in the summer of 2016 or in 2017. A comparison of average Sound Pressure Levels (SPL) in the summers of 2016 and 2017 shows that the difference in average SPL below 8 kHz is 3 dB re 1 μPa²/Hz.

北极斯瓦尔巴群岛康斯峡湾夏季声景

本文总结了部署在北极康斯峡湾（Kongsfjorden）的自主环境噪声测量系统（ANMS）在 2016 年和 2017 年夏季收集的环境噪声数据研究。这项研究的主要目标是确定 2016 年和 2017 年夏季北极环境中的各种声景成分和声景变化。这项工作主要量化夏季每个月的环境噪声源。在对数据进行分析后，确定了五个不同的声景来源，其中有三个地球物理来源，包括冰山冒泡、冰川压裂和雨水噪声，以及两个人为来源，如航运噪声和冲冰噪声。2016 年夏季和 2017 年均未发现生物源。对 2016 年和 2017 年夏季的平均声压级（SPL）进行比较后发现，8 kHz 以下的平均声压级相差 3 dB re 1 μPa2/Hz。

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
