Mooring data from Harrison Bay, Alaska, July-August 2021

Four small coastal moorings were deployed in water depths of ~5-6 meters (m) on the Colville Delta front and one site farther west for a period of approximately one week in Jul/Aug 2021. Moorings were outfitted with sensors to collect a variety of data including water levels (at all sites), turbidity/total suspended solids, water velocity, salinity, temperature, and light intensity. Light intensity measurements were also collected from a vessel-mounted sensor (included in the MM3 data package) to allow for calculation of light attenuation at the mooring. These data are described more fully in a companion publication (Eidam, "Summertime water and particle properties on an ice-influenced Arctic shelf", in prep as of March 2025).

2021年7月至8月，研究团队在科尔维尔三角洲前缘（Colville Delta front）水深约5~6米的海域布设了4套小型沿岸锚系观测系统，并在更西侧的1个站位开展观测作业，整套观测持续时长约一周。所有锚系均搭载多类传感器，用于采集各站位的水位、浊度/总悬浮固体浓度、水流速度、盐度、温度及光强数据。此外，还通过船载传感器（包含于MM3数据包中）采集光强数据，以计算各锚站位处的光衰减系数。本数据集的详细说明可参阅配套研究论文（Eidam：《受海冰影响的北极陆架夏季水体与颗粒物特性》，截至2025年3月仍在筹备中）。
