Nautical Area Scattering Coefficients (NASC) from an R/V BIP cruise in the Guaymas Basin, Gulf of California in 2013 (Jumbo Squid El Nino Response project)

<p>Integrated, area scattering values, or Natuical Area Scattering Coefficients (NASC) are provided from one cruise in the Guaymas Basin that occurred October 2013. Also included are the time (UTC) and location at the start and end of each integration bin, mean depth of the exclusion line for each bin, and the average thickness of the integrated cell.</p>

<p>Note that noise removal from this data set (e.g. splash down, electrical interference, and CTD casts) was minimal before integration. Raw acoustic scattering data (.raw files) are extremely large. These are archived at Oregon State University and will be shared using physical media upon request.</p>

<p>本数据集包含2013年10月瓜伊马斯海盆（Guaymas Basin）单次科考航次获取的积分面积散射值，即海域面积散射系数（Nautical Area Scattering Coefficients，NASC）。数据集同时涵盖各积分单元起始与结束时刻的协调世界时（UTC）及位置信息、每个积分单元对应剔除线的平均深度，以及积分单元格的平均厚度。</p><p>需注意，本数据集在积分处理前仅开展了极少量噪声剔除工作（如声脉冲入水干扰、电磁干扰及温盐深仪（CTD）下放作业带来的干扰）。原始声学散射数据（.raw文件）体量庞大，现存档于俄勒冈州立大学，可应申请通过实体存储介质共享。</p><p>相关参考文献：<br />详见Benoit-Bird与Gilly（2012）以及Hoving等（2013）的研究成果。</p><p>相关项目：<a href="http://www.bco-dmo.org/project/2279" target="_blank">低氧环境与美洲大赤鱿（Dosidicus gigas）的生态学、行为学及生理学特征</a>（http://www.bco-dmo.org/project/2279）</p>
