MR20-05C drifting wave buoy observation in the freezing marginal ice zone

Five SOFAR Spotter drifting buoys were deployed to measure trajectory and waves in the marginal ice zone during the MR20 Arctic Ocean expeditions on board R/V Mirai. The buoys were deployed on 13 and 17 October 2020. A wave event was measured between 16 and 17 October. The wind directions over the buoys were southeasterly, but the measured wave directions were southwest. The wave event is a useful dataset for studying oblique wave propagation into the MIZ. The buoys collected data until the end of October when the device's battery ran out.

在“未来”号科考船（R/V Mirai）执行的MR20北冰洋考察期间，共部署了5个SOFAR Spotter漂流浮标，用于测量边缘冰区（marginal ice zone）的轨迹与波浪。这些浮标于2020年10月13日和17日部署。2020年10月16日至17日期间观测到一次波浪事件。浮标上空的风向为东南向，但测得的波浪方向为西南向。该波浪事件是研究斜向波浪传播进入边缘冰区（MIZ）的宝贵数据集。浮标持续采集数据至10月底，直至设备电池耗尽。
