The Lamprey River Hydrological Observatory: Suburbanization And Changing Seasonality

The Lamprey River Hydrological Observatory (LRHO) is a lowland coastal watershed in southeastern New Hampshire (USA). The LRHO offers a platform to investigate the effects of suburbanization and changing seasonality on watershed hydrology, biogeochemistry, and nutrient export to an estuarine ecosystem. The LRHO utilizes a nested-watershed design to examine headwater stream and main-stem river dynamics distributed across a mixed land-use environment. Data sets from the LRHO now comprise over 20 years of weekly grab sample data as well as 7 years of high-frequency sensor data. Collectively these data sets include measures of discharge, dissolved organic matter, nutrients, cations and anions, greenhouse gases, and other physio-chemical properties. Here we share information on the setting and motivating questions of the LRHO and data availability.
