Velocity observations from a mooring at Station AT55 in Lake Michigan from 2017-08-01 to 2017-08-16.

<p>A fixed mooring was established to measure water column velocities in Lake Michigan near Milwaukee (12 km northeast of Milwaukee Harbor), WI, during 2017 from Aug 1 – Aug 17, 2017 at a 55m depth site. Site coordinates: 43^o 5.7010’ N, 87^o 46.2809’W. Neeskay cruise 1 Station AT55.</p> <p>The mooring involved a large tripod, upon which three velocimeters (Nortek Vector, Nortek Aquadopp HR profiler, Nortek Signature 500) were mounted to measure water column velocities between 13cm and 5139cm above the bed.</p>2017年8月1日至8月17日，科研团队于美国威斯康星州密尔沃基港东北12公里处的密歇根湖55米水深站点布设固定锚定观测系统，以测量该区域的水柱流速。该站点坐标为北纬43°5.7010′、西经87°46.2809′，对应Neeskay巡航1号的AT55站位。 该锚定系统搭载大型三脚架，三脚架上安装有三台流速计，分别为诺泰克Vector（Nortek Vector）、诺泰克Aquadopp HR剖面流速计（Nortek Aquadopp HR profiler）以及诺泰克Signature 500（Nortek Signature 500），用于测量湖床上方13厘米至5139厘米区间内的水柱流速。
