资源简介:
This dataset is based on acoustic recordings from five moorings deployed during the UNDER-ICE experiment in the Fram Strait. The UI1 mooring carried 8 hydrophones: HM501 (467m), HM502 (476m), HM504 (494m), HM505 (503m), HM506 (512m), HM507 (521m), HM509 (530m), HM310 (539m). A total of 8188 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI2 mooring carried 10 hydrophones: HM511 (336m), HM512 (327m), HM513 (318m), HM514 (309m), HM515 (300m), HM516 (291m), HM517 (282m), HM518 (273m), HM519 (264m), HM320 (255m). A total of 4358 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI3 mooring carried 10 hydrophones: HM521 (317m), HM522 (308m), HM523 (299m), HM524 (290m), HM525 (281m), HM526 (272m), HM527 (263m), HM528 (254m), HM529 (245m), HM330 (236m). A total of 8188 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI4 mooring carried 10 hydrophones: HM531 (313m), HM532 (304m), HM533 (295m), HM534 (286m), HM535 (277m), HM536 (268m), HM537 (259m), HM538 (250m), HM539 (241m), HM340 (232). A total of 8189 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Jan 2016. The UI5 mooring carried 9 hydrophones: HM542 (565m), HM543 (556m), HM544 (547m), HM545 (538m), HM546 (529m), HM547 (520m), HM548 (511m), HM549 (502m), HM550 (493m). A total of 4359 recordings were obtained from each hydrophone every 3 hours from Sep 2014 - Mar 2016. Each acoustic recording covered 130 s with sampling rate 1000Hz. 10-, 50- and 90- percentiles of sound pressure and power were calculated for each reception using 50 % overlapping Hanning window with a window length of 1024 samples. The units for sound pressure is Pa. The unit for power (ocean sound level) is dB re uPa2 Hz-1. Noise by cable strumming is included. The processing is described in Geyer et al. 2021 https://doi.org/10.1121/2.0001507.

本数据集源自弗拉姆海峡(Fram Strait)UNDER-ICE实验期间部署的5套锚系声学采集系统获取的声学录音。UI1锚系搭载8台水听器(hydrophone):HM501(467米)、HM502(476米)、HM504(494米)、HM505(503米)、HM506(512米)、HM507(521米)、HM509(530米)、HM310(539米)。在2014年9月至2016年1月期间,每台水听器每3小时可获取共计8188条录音。UI2锚系搭载10台水听器:HM511(336米)、HM512(327米)、HM513(318米)、HM514(309米)、HM515(300米)、HM516(291米)、HM517(282米)、HM518(273米)、HM519(264米)、HM320(255米)。在2014年9月至2016年1月期间,每台水听器每3小时可获取共计4358条录音。UI3锚系搭载10台水听器:HM521(317米)、HM522(308米)、HM523(299米)、HM524(290米)、HM525(281米)、HM526(272米)、HM527(263米)、HM528(254米)、HM529(245米)、HM330(236米)。在2014年9月至2016年1月期间,每台水听器每3小时可获取共计8188条录音。UI4锚系搭载10台水听器:HM531(313米)、HM532(304米)、HM533(295米)、HM534(286米)、HM535(277米)、HM536(268米)、HM537(259米)、HM538(250米)、HM539(241米)、HM340(232米)。在2014年9月至2016年1月期间,每台水听器每3小时可获取共计8189条录音。UI5锚系搭载9台水听器:HM542(565米)、HM543(556米)、HM544(547米)、HM545(538米)、HM546(529米)、HM547(520米)、HM548(511米)、HM549(502米)、HM550(493米)。在2014年9月至2016年3月期间,每台水听器每3小时可获取共计4359条录音。每条声学录音时长为130秒,采样率为1000Hz。针对每次接收信号,采用窗长1024个采样点、50%重叠的汉宁窗(Hanning window),计算声压与声功率的10分位数、50分位数及90分位数。声压单位为帕斯卡(Pa),声功率(海洋声级)单位为dB re μPa²·Hz⁻¹。数据包含缆绳震颤产生的噪声。相关数据处理流程详见Geyer等人2021年发表的研究(https://doi.org/10.1121/2.0001507)。
