North Temperate Lakes LTER: High Frequency Meteorological and Dissolved Oxygen Data - Sparkling Bog North Buoy 2008 - 2012

The instrumented buoy on Sparkling Bog North is equipped with a dissolved oxygen sensor,
a thermistor chain, and meteorological sensors that provide fundamental information on lake
thermal structure, weather conditions, and lake metabolism. Data are usually collected
either at 1 minute or 10 minute intervals. The D-Opto dissolved oxygen sensor is 0.5m from
the lake surface, thermistors are at the surface, at 0.25 m and at every .5 m from 0.5 m to
4.5 m, and meteorological sensors measure wind speed, wind direction, relative humidity, and
air temperature. The buoy is also equipped with a CO2 monitor and a YSI AutoProfiler that
measures several parameters including dissolved oxygen, water temperature, conductivity, pH,
ORP, turbulence and chlorophyll-a. After correcting for flux to or from the atmosphere and
vertical mixing within the water column, high frequency measurements of dissolved gases such
as carbon dioxide and oxygen can be used to estimate gross primary productivity,
respiration, and net ecosystem productivity, the basic components of whole lake metabolism.
Sampling Frequency: varies for instantaneous sample. Generally 1 minute or 10 minutes.
Number of sites: 1

Sparkling Bog North水域的搭载观测传感器的浮标配备了溶解氧传感器（dissolved oxygen sensor）、热敏电阻链（thermistor chain）与气象传感器（meteorological sensors），可提供湖泊热结构（lake thermal structure）、气象条件及湖泊代谢（lake metabolism）的基础信息。数据采集的时间间隔通常为1分钟或10分钟。该D-Opto型溶解氧传感器（D-Opto dissolved oxygen sensor）安装于距湖面0.5米处；热敏电阻分别布设于湖面、0.25米水深处，以及0.5米至4.5米水深区间内每0.5米一处的位置；气象传感器用于测量风速、风向、相对湿度与气温。该浮标还搭载了CO₂监测仪，以及可测量溶解氧、水温、电导率、pH、氧化还原电位（ORP）、湍流及叶绿素a（chlorophyll-a）等多项参数的YSI AutoProfiler分析仪。在修正大气与水柱间的气体交换通量及水柱内的水体垂直混合效应后，二氧化碳、氧气等溶解气体的高频测量数据可用于估算总初级生产力（gross primary productivity）、呼吸作用（respiration）与生态系统净生产力（net ecosystem productivity），这三者是全湖代谢（whole lake metabolism）的基本组成部分。采样频率：瞬时采样的频率存在差异，通常为1分钟或10分钟。监测点位数量：1个
