The Bear Brook Watershed in Maine, USA: Long-term stream chemistry 1986 - 2016

General Information

Data Package:
Local Identifier:	edi.621.1
Title:	The Bear Brook Watershed in Maine, USA: Long-term stream chemistry 1986 - 2016
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This dataset includes stream chemistry for the Bear Brook Watershed in Maine (BBWM). The BBWM consists of two watersheds, the reference East Bear (EB), receiving ambient deposition, and the treated West Bear (WB), which received experimental elevated N+S deposition for 27 years. Stream samples were collected as grab samples and event samples (e.g. during snowmelt and rain events) using ISCO™ automated samplers from both EB and WB streams. Stream chemistry was interpolated between collections to develop annual or monthly stream water fluxes.

Sampling Site:

Description:

BBWM is located in eastern Maine, USA at an elevation of 450.8 m. Soils are coarse-loamy, mixed, frigid Typic and Aquic Haplorthods. Bedrock consists dominantly of quartzite, phyllite, and calc-silicate low-grade metasediments, and minor granite dikes. The lower elevations are dominated by hardwood stands, and the upper elevations are dominated by softwood stands. The site is located in the Acadian Plains and Hills (82) Level III Ecoregion (Omernik et al. https://www.epa.gov/eco-research/ecoregions).
