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

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: Chris Solomon (Cary IES), Emily Bernhardt (Duke), Bill McDowell (UNH), Charley Driscoll (Syracuse U.), Keith Nislow (USFS), and Mark Green (Case Western). Current Financial Support for HBWatER is provided by NSF LTREB # 2401760 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.

《哈伯德布鲁克流域溪流与降水化学记录》（The Hubbard Brook Watershed Stream and Precipitation Chemistry Record）是一套降水与溪流水样的化学浓度数据集，该数据集自1963年夏季起，每周在美国新罕布什尔州怀特山脉内的哈伯德布鲁克实验林（Hubbard Brook Experimental Forest）全境的溪流与降水监测站点采集样本。HBWatER（HBWatER）目前每周从9个监测流域、各小型溪流汇入的哈伯德布鲁克干流，以及2个长期降水采集站点采集样本。HBWatER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，四人最初便开展了溪流水与降水（雨雪）样本的采集与分析工作。他们提出了一套简洁的研究思路：通过对比降水、降雪带来的流域输入通量与溪流输出的物质通量，即可量化整个生态系统对大气污染或林业经营活动的响应规律。自1963年至今，该项目始终坚持每周采集溪流水与降水样本。依托对这套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。当前，HBWatER的样本采集与分析工作由卡里生态系统研究所（Cary IES）的塔米·伍斯特（Tammy Wooster）与美国林务局（USFS）的杰夫·梅里亚姆（Jeff Merriam）负责维持；数据集的管理与维护工作则由一支研究者团队承担，成员包括克里斯·所罗门（Chris Solomon，Cary IES）、艾米丽·伯恩哈特（Emily Bernhardt，杜克大学）、比尔·麦克道威尔（Bill McDowell，新罕布什尔大学University of New Hampshire, UNH）、查理·德里斯科尔（Charley Driscoll，雪城大学Syracuse University, Syracuse U.）、基思·尼斯洛（Keith Nislow，USFS）与马克·格林（Mark Green，凯斯西储大学Case Western Reserve University, Case Western）。HBWatER当前的经费支持来自美国国家科学基金会长期生态生物学研究项目（NSF LTREB #2401760）与美国农业部林务局北方研究站。这些数据作为哈伯德布鲁克生态系统研究（Hubbard Brook Ecosystem Study, HBES）的一部分采集得到，而HBES是依托哈伯德布鲁克实验林开展的协同研究项目，该实验林由美国农业部林务局北方研究站运营维护。
