Abstract:	The Lake Sunapee Protective Association (Sunapee, New Hampshire, USA) has been operating an instrumented buoy on Lake Sunapee (maximum depth 33.7 meters) beginning on 27 August 2007. The environmental sensors on the buoy from 2007 - 2013 provided information on weather conditions, lake thermal structure, and oxygen dynamics, and their data can be used to calculate physical and biological variables such as buoyancy frequency, thermocline depth, thermal stability, and lake metabolism. The sensors were programmed to collect environmental data every 10 minutes. The buoy collected meteorological data 1.7 meters above the lake surface, including wind speed and direction (Vaisala WXT52 anemometer), air temperature and humidity (Vaisala HMP50), and photosynthetically active radiation (PAR Li-Cor). The water temperature sensors (TempLine thermistors from Apprise Technology in 2007-2010; NexSens T-node sensors 2010-2013) were situated at 0.5-2 meter intervals from 0-14 meters deep with the bottom sensor approximately 1 meter from the sediments. The dissolved oxygen (Zebra-Tech d-opto) sensor was deployed at approximately 1 meter below the surface and recorded oxygen concentration (mg/L), oxygen saturation (%), and temperature at the sensor (oxygen saturation is not included in this dataset). The buoy was anchored at approximately 15 meter deep water near the Loon Island lighthouse in the northern half of the lake, near the deepest part of the lake (43.390 N, -72.057 W). During the winter of 2007 - 2008, the buoy froze into the ice and continually recorded data with the uppermost thermistor below the bottom of the ice. In winter of 2008 - 2009, the buoy was damaged by ice and data were not collected until re-deployment on 29 July 2009. In subsequent years, the buoy was deployed from April or May to October or November at the Loon Island location and limited data were obtained during the winter months at the Sunapee Harbor (43.386 N, -72.081 W). In 2013, the buoy was taken offline for a 15-day period (27 August – 10 September 2013) to add additional sensors. This dataset has been modified (removing obviously errant readings and drift-correcting dissolved oxygen) from the raw data for the purposes of the associated manuscript, Richardson et al. (2016). Though only partial data was referenced in that publication, the entire available record for the 2007-2013 time period is included in this dataset.

Description:

All buoy sensor datasets were carefully examined using a standardized quality control/quality analysis process similar to that described in Bruesewitz et al. (2015). The DO sensor, as expected, was subject to drift throughout each year. Manually-collected monthly DO profiles with a HQ40 Hach multi-parameter meter (Hach Inc., Loveland, CO, USA) at the buoy site during 2007–2013 confirmed that the lake was at or near saturation at 1 m depth throughout the May–October monitoring period (LSPA, unpubl. data). To correct for sensor drift, we compared the measured buoy sensor DO with the saturated DO concentration calculated from the water temperature at 1 m depth and the mean atmospheric pressure for each day, following Weiss (1970). We subtracted those two DO concentrations to calculate a correction factor for all raw buoy sensor DO values for each day. The corrected DO values consistently compared well to the manually collected DO concentrations (n = 18 across all years, r = 0.69, p = 0.002). Buoy is outfitted with one wind speed and direction sensor (Vaisala WXT52 anemometer), air temperature and relative humidity sensor (Vaisala HMP50), photosynthetically active radiation sensor (PAR LI-COR: LI-CORLI190SB) and a compass (Honeywell HMR 3000) approximately 1.7 meters above the water. Temperature sensors were TempLine thermistors from Apprise Technology (2007-2010, n = 16, approximate depth of sensors were 0-3 meters at half meter intervals, 4-11 meters at one meter intervals, and 13 meters) and were replaced by Nexsens T500 T-Node sensors (n = 10, approximate depth 1-10 meters at one meter intervals). A Zebra Tech d-opto with SDI 12 datalogger interface recorded dissolved oxygen saturation, concentration and water temperature at approximately 1 meter depth.
