Continuous precipitation and stream chemistry data, Hubbard Brook Ecosystem Study, 1963 – present.

The Hubbard Brook Watershed Stream and Precipitation Chemistry Record
is a dataset of chemical concentration data for precipitation and
streamwater samples that have been collected weekly since the summer
of 1963 from streams and precipitation gauges throughout the Hubbard
Brook Experimental Forest, a research forest in the White Mountains of
New Hampshire. HBWatER currently collects weekly samples from nine
gauged watersheds, the mainstem of the Hubbard Brook into which each
small stream drains, and two long-term precipitation collection sites.
HBWatER was begun in the 1960's by Gene E. Likens, F. Herbert Bormann,
Robert S. Pierce, and Noye M. Johnson who began collecting and
analyzing stream and precipitation (rain and snow). They had a simple
idea, that by comparing watershed inputs in rain and snow to watershed
outputs from streams, they could measure the behavior of entire
ecosystems in response to atmospheric pollution or forestry practices.
Stream and precipitation samples have been collected every week from
1963 to the present day. Insights gained from studying this long-term
chemical record led to the discovery of acid rain in North America and
have documented the effectiveness of federal clean air legislation in
reducing coalfired power plant emissions.

The collection and analysis of HBWatER samples is currently sustained
by Tammy Wooster (Cary IES) and Jeff Merriam (USFS) and the dataset is
curated and maintained by a team of researchers: Emma Rosi (Cary IES),
Emily Bernhardt (Duke), Lindsey Rustad (USFS), John Campbell (USFS),
Bill McDowell (UNH), Charley Driscoll (Syracuse U.), Mark Green (Case
Western), and Scott Bailey (USFS). Current Financial Support for
HBWatER is provided by NSF LTREB # 1907683 and the USDA Forest Service
Northern Research Station.

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.

哈伯布鲁克流域溪流与降水化学记录是一套涵盖降水与溪流水样品化学浓度数据的数据集，其样品自1963年夏季起，每周采集自新罕布什尔州怀特山脉内的哈伯布鲁克实验林全境的溪流与降水监测站点。HBWatER 目前每周从9个设有监测装置的流域、各小型溪流汇入的哈伯布鲁克干流，以及2个长期降水采集站点采集样品。该数据集由吉恩·E·利肯斯（Gene E. Likens）、F·赫伯特·博尔曼（F. Herbert Bormann）、罗伯特·S·皮尔斯（Robert S. Pierce）与诺耶·M·约翰逊（Noye M. Johnson）于20世纪60年代创立，四人最初启动了溪流与降水（雨雪）样品的采集与分析工作。他们提出了简洁的核心研究思路：通过对比流域的雨雪输入与溪流输出，即可量化完整生态系统对大气污染或林业经营活动的响应特征。自1963年至今，研究团队始终坚持每周采集溪流与降水样品。依托对这一长期化学记录的研究，学界不仅发现了北美地区的酸雨现象，还证实了联邦清洁空气法案在降低燃煤电厂排放方面的实际成效。

目前，HBWatER的样品采集与分析工作由塔米·伍斯特（Tammy Wooster，卡里环境研究所（Cary IES））与杰夫·梅里亚姆（Jeff Merriam，美国林务局（USFS））负责；数据集的编目与维护工作由一支研究团队承担，成员包括艾玛·罗西（Emma Rosi，Cary IES）、艾米丽·伯恩哈特（Emily Bernhardt，杜克大学）、林赛·拉斯塔德（Lindsey Rustad，USFS）、约翰·坎贝尔（John Campbell，USFS）、比尔·麦克道威尔（Bill McDowell，新罕布什尔大学）、查理·德里斯科尔（Charley Driscoll，雪城大学）、马克·格林（Mark Green，凯斯西储大学）与斯科特·贝利（Scott Bailey，USFS）。HBWatER 当前的资金支持来自美国国家科学基金会长期生态研究项目（NSF LTREB # 1907683）与美国农业部林务局北部研究站。

该批数据作为哈伯布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）的组成部分采集获得。HBES 是在哈伯布鲁克实验林开展的协作研究项目，该实验林由美国农业部林务局北部研究站运营维护。
