North Temperate Lakes LTER: High Frequency Meteorological - Trout Lake Buoy2 - ADCP 2005 - 2006

This instrumented buoy on Trout Lake is equipped with a thermistor chain and
meteorological sensors that provide fundamental information on lake thermal structure,
weather conditions, and lake metabolism. An acoustic Doppler current profiler (ADCP) is
associated with this buoy. Data are usually collected every 10 minutes with occasional
periods of 2 minute data for short periods to answer specific questions. The thermistors are
placed every 0.5-1m from the surface through 13m, and meteorological sensors measure
relative humidity, air temperature and wind parameters. In the fall of 2005, the buoy also
included 4 Greenspan dissolved oxygen sensors placed at depths from the lake surface to 10m.
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. averaged to hourly and daily values from one minute samples Number of sites: 1

特劳特湖（Trout Lake）上的搭载式观测浮标配备了热敏电阻链与气象传感器，可获取湖泊热结构、气象条件及湖泊代谢相关的基础数据。该浮标还配套搭载了声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）。
数据采集频次通常为每10分钟一次，偶尔会在短时段内采用2分钟间隔的采集模式，以响应特定研究需求。
热敏电阻传感器沿水体深度从湖面至13米处，以0.5-1米的间距布设；气象传感器则监测相对湿度、气温与风参数等相关指标。
2005年秋季，该浮标额外增设了4台格林斯潘型溶解氧传感器（Greenspan dissolved oxygen sensors），布设深度范围为湖面至10米处。
在修正了大气与水体间的气体交换通量以及水柱内的垂直混合效应后，溶解气体（如二氧化碳与氧气）的高频监测数据可用于估算总初级生产力、呼吸作用与生态系统净生产力，上述指标均为全湖代谢的核心组成部分。
采样频次：瞬时采样的频次存在差异；基于1分钟采样数据可生成小时级与日级的平均数据集。
监测点位数量：1个。
