Underwater temperature and light data from 3 mini-buoys in Lake Sunapee, NH, USA from June – October 2018

Three mini-buoys were deployed during a portion of the ice-off period of 2018 in Lake Sunapee, NH, USA with HOBO temperature sensors at various depths below the water’s surface. Temperature data were collected using HOBO pendant temperature and HOBO pendant temperature/light sensors at descending depths between 0.1m and the nearest whole and/or half meter increments below the water surface and above the sediment/water interface at 10 minute intervals. The buoys were located in cove areas of the lake in the north east arm of the lake (Herrick Cove, 0.1m – 6.5m), the west side of the southern area of the lake near Lake Sunapee State Beach (State Beach, 0.1m – 2.5m) and the northwest arm of the lake (George’s Mills, 0.1m -7m). This data has been QAQC’d to remove obviously errant data and artifacts of buoy maintenance visits.

2018年美国新罕布什尔州萨纳皮湖（Lake Sunapee）于融冰阶段的部分时段内，部署三台小型浮标，浮标搭载HOBO温度传感器（HOBO temperature sensors），布设于水面以下不同深度。本次研究采用HOBO Pendant型温度传感器与HOBO Pendant型温光复合传感器，沿水深梯度布设，起始深度为0.1米，按最近的整米或半米增量依次向下布设，覆盖范围为水面以下至沉积物-水界面上方区域，以10分钟为采样间隔采集温度数据。三台浮标分别设于该湖三处湾域：湖东北岸的赫里克湾（Herrick Cove），布设深度范围为0.1米至6.5米；湖南部区域西岸的萨纳皮湖州立海滩（Lake Sunapee State Beach）附近水域（州立海滩测点），布设深度范围为0.1米至2.5米；湖西北岸的乔治米尔（George’s Mills）水域，布设深度范围为0.1米至7米。本数据集已完成QAQC（质量控制与质量保证）处理，剔除了明显的异常数据及浮标维护作业产生的伪迹数据。
