蓝藻有害藻华 (cyanoHABs) 是水生环境中一个日益严重的问题。在这里，描述了一种新的数据浮标系统（即“黑豹浮标”），用于监测 cyanoHAB 和相关条件。该系统在紧凑的平台上使用定制的开源数据记录器、嵌入式调制解调器和带有现成传感器的太阳能充电调节器。Panther 浮标部署在美国绿湾和美国使徒群岛的苏必利尔湖，以监测水温的深度和叶绿素-a 和藻蓝蛋白荧光。在密尔沃基的鲟鱼湾和 Summerfest 泻湖部署了额外的 Panther 浮标，以随深度监测风温和水温。在每次部署 10-30K 采样事件的 98 ± 10% 的数据传输中，每 2-10 分钟传输一次蜂窝数据。R = 0.99 和P < 0.001），商业传感器的精度在 0.31 °C 以内。苏必利尔湖和绿湾的黑豹浮标检测到藻蓝蛋白或叶绿素-a 荧光增加，表明发生了中度水华事件。Summerfest 泻湖和鲟鱼湾的风测量与商业风传感器显着相关。总之，这些部署表明 Panther 浮标系统是监测 cyanoHAB 和相关条件的可靠设备。

Real-Time Monitoring of Cyanobacterial Harmful Algal Blooms with the Panther Buoy

Cyanobacterial harmful algal blooms (cyanoHABs) are a growing problem in aquatic environments. Here, a new data buoy system is described (i.e., “the Panther buoy”) for monitoring cyanoHABs and associated conditions. The system uses a custom open-source data logger, an embedded modem, and a solar charge regulator with off-the-shelf sensors on a compact platform. Panther buoys were deployed in Green Bay, USA, and Lake Superior at the Apostle Islands, USA, to monitor water temperature with depth and chlorophyll-a and phycocyanin fluorescence. Additional Panther buoys were deployed in Sturgeon Bay and Summerfest Lagoon, Milwaukee, to monitor wind and water temperature with depth. Cellular data were transmitted every 2–10 min in 98 ± 10% of data transmissions of 10–30K sampling events per deployment. A new temperature chain is described and shown to have high precision (R = 0.99 and P < 0.001) and accuracy within 0.31 °C of commercial sensors. Panther buoys in Lake Superior and Green Bay detected increases in phycocyanin or chlorophyll-a fluorescence, indicative of moderate bloom events. Wind measurements in Summerfest Lagoon and Sturgeon Bay were significantly correlated with commercial wind sensors. Altogether, these deployments indicate that the Panther buoy system is a reliable device for monitoring cyanoHABs and associated conditions.
