Hubbard Brook Experimental Forest: Chemistry of Mirror Lake water column 1967 - 2010

Numerous studies have been conducted on Mirror Lake
since the mid-1960s, including extensive physical, chemical,
biological, and paleoecological research (Likens 1985). This
data set includes chemistry data for water samples collected
approximately monthly at an anchored buoy station located at
the deepest part (11 m at full pool) of Mirror Lake.
Measurements include ANC, DIC, DO, base cations, pH,
ammonium, anions, temperature and dissolved silica. These data were gathered as part of the Hubbard Brook
Ecosystem Study (HBES). The HBES is a collaborative effort at
the Hubbard Brook Experimental Forest, which is operated and
maintained by the USDA Forest Service, Northern Research
Station.

自20世纪60年代中期以来，学界已针对镜湖（Mirror Lake）开展了大量研究，涵盖系统的物理、化学、生物及古生态相关调研（Likens, 1985）。本数据集收录了镜湖最深处（满水位时水深11米）的锚定浮标站采集的水样化学分析数据，采样频率约为每月一次。检测指标包括酸中和容量（Acid Neutralizing Capacity, ANC）、溶解无机碳（Dissolved Inorganic Carbon, DIC）、溶解氧（Dissolved Oxygen, DO）、碱阳离子、pH值、铵根离子、阴离子、水温与溶解态二氧化硅。
本数据集的相关数据采集工作隶属于哈伯布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）项目。该项目是在哈伯布鲁克实验林开展的协同研究计划，实验林由美国农业部林务局北方研究站（USDA Forest Service, Northern Research Station）运营维护。
