The Intensity, Directionality, and Statistics of Underwater Noise From Melting Icebergs

Glowacki Oskar; Deane Grant B.; Moskalik Mateusz

摘要

Abstract >Freshwater fluxes from melting icebergs and glaciers are important contributors to both sea level rise and anomalies of seawater salinity in polar regions. However, the hazards encountered close to icebergs and glaciers make it difficult to quantify their melt rates directly, motivating the development of cryoacoustics as a remote sensing technique. Recent studies have shown a qualitative link between ice melting and the accompanying underwater noise, but the properties of this signal remain poorly understood. Here we examine the intensity, directionality, and temporal statistics of the underwater noise radiated by melting icebergs in Hornsund Fjord, Svalbard, using a three‐element acoustic array. We present the first estimate of noise energy per unit area associated with iceberg melt and demonstrate its qualitative dependence on exposure to surface current. Finally, we show that the analysis of noise directionality and statistics makes it possible to distinguish iceberg melt from the glacier terminus melt. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >熔化冰山和冰川的淡水势态是海平面上升和海水异常的重要贡献者极地地区的盐度。然而，冰山和冰川附近遇到的危害使得难以直接量化其熔体率，激励冷冻声作为遥感技术的发展。最近的研究表明了冰熔化和随附的水下噪声之间的定性联系，但这种信号的性质仍然明白很差。在这里，我们使用三个元件声学阵列来检查通过苏尔巴德·斯瓦尔巴德熔炼冰山辐射的水下噪声的强度，方向性和时间统计。我们介绍了与冰山熔融相关的每单位面积的噪声能量的第一估计，并证明其对表面电流暴露的定性依赖性。最后，我们表明噪声方向性和统计数据的分析使得可以将冰山熔体与冰川末端熔体区分开来。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-23539/'>《Geophysical Research Letters》</a> <b style="margin: 0 2px;">|</b><span>2018年第9期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Glowacki Oskar&option=202" target="_blank" rel="nofollow">Glowacki Oskar;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Deane Grant B.&option=202" target="_blank" rel="nofollow">Deane Grant B.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Moskalik Mateusz&option=202" target="_blank" rel="nofollow">Moskalik Mateusz;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Institute of GeophysicsPolish Academy of SciencesWarsaw Poland;</p> <p>Scripps Institution of OceanographyUniversity of California San DiegoLa Jolla CA USA;</p> <p>Institute of GeophysicsPolish Academy of SciencesWarsaw Poland;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/163.html" title="地球物理学">地球物理学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=glacier&option=203" rel="nofollow">glacier;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=iceberg&option=203" rel="nofollow">iceberg;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ice melting&option=203" rel="nofollow">ice melting;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=melt rate&option=203" rel="nofollow">melt rate;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=underwater acoustics&option=203" rel="nofollow">underwater acoustics;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ambient noise oceanography&option=203" rel="nofollow">ambient noise oceanography;</a> </p> <div class="translation"> 机译：冰川;冰山;冰融化;熔融率;水下声学;环境噪声海洋学;
