自1985年以来，由苏必利尔湖上的浮标测量到的水表温度以每10年增长1.2度的速率上升，比湖面上方的空气升温速率快15%，并且是湖周围陆地升温速率的2倍。
Since 1985, surface water temperatures measured by lake buoys have climbed 1.2 degrees per decade, about 15 percent faster than the air above the lake and twice as fast as warming over nearby land.
浮标所携带的传感器组可以测量35种以上的参数，从风力到水的化学成分(对于预测和报告天气非常重要)、海洋状况和水质。
The buoys carry sensor arrays that measure over 35 different parameters, from wind to water chemistry, that are vital for reporting and predicting weather, sea conditions, and water quality.
硬件部分采用51系列单片机实现，水下测量浮标通过RS - 485串行口与岸站接收处理系统进行通讯。
Microcontroller of 51 series is applied in the hardware and the underwater buoy communicates with the receiving and processing system of the land station by RS-485 serial interfaces.
