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)
收藏资源简介：
<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>Related References:<br /> See Benoit-Bird & Gilly (2012) and Hoving et al.

本数据集收录了2013年10月于瓜伊马斯海盆开展的单次科考航次的积分面积散射值，亦称海区散射系数（Nautical Area Scattering Coefficients，NASC）。数据集同时包含各积分单元的起止时刻（UTC时间）与位置、各单元排除线的平均深度，以及积分格点的平均厚度。 请注意，本数据集在积分处理前仅进行了极少量的噪声剔除工作，涉及溅落干扰、电磁干扰及CTD（温盐深仪）施放过程干扰等类型。原始声学散射数据（.raw格式文件）体量极大，目前存档于俄勒冈州立大学，可根据申请通过实体存储介质共享。 相关参考文献： 详见Benoit-Bird与Gilly（2012）以及Hoving等（2013）的研究成果。 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、行为及生理特征</a>（http://www.bco-dmo.org/project/2279）
