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数据集（Hubbard Brook Watershed Stream and Precipitation Chemistry Record）是一套收录降水与溪流水样品化学浓度数据的数据集，相关样品自1963年夏季起，每周在新罕布什尔州怀特山脉内的哈伯布鲁克实验林（Hubbard Brook Experimental Forest）全域的溪流与降水测站中采集。该数据集（下文简称HBWatER）当前按周采集9个带测流装置的流域、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的样品。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，四人最初便启动了溪流与降水（雨雪）样品的采集与分析工作。他们的核心研究构想十分简洁：通过对比流域的雨雪输入通量与溪流输出通量，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过程。自1963年至今，该数据集的溪流与降水样品采集工作始终按周持续开展。通过对这一长期化学记录的研究，学界不仅首次在北美发现了酸雨现象，还通过数据验证了联邦清洁空气法案在削减燃煤电厂排放方面的实际成效。当前HBWatER的样品采集与分析工作由塔米·伍斯特（Tammy Wooster，卡里生态系统研究所Cary IES）与杰夫·梅里姆（Jeff Merriam，美国林务局USFS）负责推进；数据集的典藏与运维工作则由以下研究团队共同承担：艾玛·罗西（Emma Rosi，卡里生态系统研究所）、埃米莉·伯恩哈特（Emily Bernhardt，杜克大学）、林赛·拉斯塔德（Lindsey Rustad，美国林务局）、约翰·坎贝尔（John Campbell，美国林务局）、比尔·麦克道威尔（Bill McDowell，新罕布什尔大学UNH）、查理·德里斯科尔（Charley Driscoll，雪城大学Syracuse U.）、马克·格林（Mark Green，凯斯西储大学Case Western）以及斯科特·贝利（Scott Bailey，美国林务局）。HBWatER当前的经费支持来自美国国家科学基金会长期生态研究项目（NSF LTREB #1907683）以及美国农业部林务局北方研究站。本数据集的相关数据均采集自哈伯布鲁克生态系统研究（Hubbard Brook Ecosystem Study，下文简称HBES）项目。HBES是哈伯布鲁克实验林内的协同研究计划，该实验林由美国农业部林务局北方研究站运营维护。
