Mooring data from Harrison Bay, Alaska, August-September 2022

Six small coastal moorings were deployed in Harrison Bay for approximately 30 days between early August and early September. Two moorings were outfitted with Nortek Aquadopps and optical backscatter sensors and the remainder were outfitted with RBR sensors which recorded some combination of salinity, temperature, pressure, and turbidity. All sensors were mounted within approximately 0.5 meters (m) of the bed to capture boundary-layer dynamics. Turbidity values were converted to total suspended solids concentrations. Wave parameters (significant wave height, peak wave period, and wave direction) were post-processed from Aquadopp data. Shear velocities (used in sediment-transport research) were calculated from current and wave data at the sites where Aquadopps were mounted. Data have been used in support of a publication, "Summertime sediment convergence on the Alaskan Beaufort Shelf and implications for ice rafting."

研究团队于8月初至9月初在哈里森湾（Harrison Bay）部署了6套小型沿海锚定观测系统，观测时长约30天。其中2套锚定系统配备了Nortek Aquadopp声学多普勒海流剖面仪与光学后向散射传感器，剩余4套则搭载了RBR传感器，可同步记录盐度、温度、压强与浊度中的一项或多项参数。所有传感器均安装于距海底床面约0.5米范围内，以捕捉边界层动力学过程。浊度数值已被转换为总悬浮固体浓度。基于Aquadopp采集的数据，可后处理得到波浪参数（有效波高、峰值波周期与波浪方向）。针对部署了Aquadopp的观测站点，研究人员从海流与波浪数据中计算得到了沉积物输运研究中常用的剪切流速。本数据集已用于支撑一篇题为《阿拉斯加波弗特陆架夏季沉积物汇聚过程及其对冰筏搬运的启示》的学术论文发表。
