Microstructure profiles at Station AT55 in Lake Michigan from 2017, 2018 and 2019.

<p>Turbulent microstructure profiles were collected near Milwaukee, WI, during 2017 (August 1 - August 16), 2018 (April 5 – April 20), and 2019 (May 13 - May 14) at a 55m depth site. Microstructure measurements were collected using an RSI MicroCTD (Rockland Scientific International, Inc.), which measures velocity shear, temperature, turbidity, and chlorophyll concentrations. High resolution velocity shear (512 Hz) measurements were used to estimate turbulent kinetic energy dissipation throughout the water column. Microstructure profiles were collected during fair weather conditions on each day of sampling.</p>本数据集采集了美国威斯康星州（WI）密尔沃基（Milwaukee）附近海域55米水深站位的湍流微结构剖面数据，采集时段涵盖2017年（8月1日至8月16日）、2018年（4月5日至4月20日）以及2019年（5月13日至5月14日）。微结构测量采用RSI MicroCTD（Rockland Scientific International, Inc.，罗克兰科学国际公司）开展，该设备可同步测量流速切变、温度、浊度与叶绿素浓度。高分辨率流速切变测量（采样频率512赫兹）数据被用于估算整个水柱的湍流动能耗散率。所有采样当日均为晴朗天气，在此期间完成了全部微结构剖面数据的采集工作。
