Title: Walker Branch Watershed: Effect of Dual Nitrogen and Phosphorus Additions on Nutrient Uptake and Saturation Kinetics, 2011-2012

Abstract

This data set reports the results of field experiments investigating the effect of dual nutrient (nitrogen and phosphorus) additions on nutrient uptake and saturation kinetics in the West Fork of Walker Branch Watershed, a forested headwater stream on the Oak Ridge Reservation in east Tennessee. The experiments were carried out in the autumn of 2011 and spring of 2012 to examine seasonality in nutrient dynamics. The nutrient limitation status (N-limited, P-limited, co-limited for N and P, or neither N- nor P-limited) of Walker Branch was examined using nutrient diffusing substrata (NDS) in both autumn and spring. Next, a combination of instantaneous and steady-state nutrient releases were used to examine the effect of dual N and P releases on nutrient dynamics and saturation kinetics. Lastly, because the nutrient release results from autumn suggested a strong role of P sorption in P dynamics, laboratory assays were carried out in spring to quantify the importance of P sorption to sediments in Walker Branch.

Influence of dual nitrogen and phosphorus additions on nutrient uptake and saturation kinetics in a forested headwater stream

Journal Article Griffiths, Natalie A. ; Johnson, Laura T. - Freshwater Science

Nitrogen (N) and phosphorus (P) can limit autotrophic and heterotrophic metabolism in lotic ecosystems, yet most studies that evaluate biotic responses to colimitation focus on patch-scale (e.g., nutrient diffusing substrata) rather than stream-scale responses. In this study, we evaluated the effects of single and dual N and P additions on ambient nutrient uptake rates and saturation kinetics during two biologically contrasting seasons (spring, autumn) in Walker Branch, a temperate forested headwater stream in Tennessee, USA. In each season, we used separate instantaneous pulse additions to quantify nutrient uptake rates and saturation kinetics of N (nitrate) and P (phosphate). We thenmore »« less

Walker Branch Watershed: Hourly, Daily, and Annual Precipitation

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports hourly, daily, and annual precipitation in Walker Branch Watershed (WBW). The long-term Walker Branch Hydrology Monitoring project was intended to document changes in the water balance (precipitation inputs, stream discharge outputs) for the WBW over time. This data set contains three data files of precipitation amount for hourly, monthly, and annual intervals for the years 1969 through 2012. Five rain gauges were used from 1969-1979, and two rain gauges were used from 1980-2012.
Walker Branch Watershed: Daily Climate and Soil Temperature Data

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports daily climate and soil temperature data for Walker Branch Watershed. As part of the long-term Walker Branch project, daily climate and soil temperature data were collected using instruments on a meteorological tower located in an upper slope of the watershed. This data set contains one data file of daily climate and soil temperature data from 1993 through 2010. Measurement collection began in 1993 as part of the Throughfall Displacement Experiment (TDE) in the control (ambient) plot. Measurements include daily integrated values for above canopy incident photosynthetically active radiation, above canopy incident total radiation, air temperature, relativemore »« less

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports 15-minute and daily stream discharge, and annual runoff for the West and East Forks draining Walker Branch Watershed (WBW). The long-term Walker Branch Hydrology Monitoring project was intended to document changes in the water balance (precipitation inputs, stream discharge outputs) for the WBW over time. This data set contains three data files of stream discharge (L/s) for 15-minute and daily intervals, and annual runoff (cm). The daily and annual datasets began in 1969 in both East and West Forks, while the 15-minute datasets began in 1994 in both Forks. Data were collected through 2014 for themore »« less
Walker Branch Watershed: Weekly Stream Water Chemistry

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports weekly stream water chemistry in the West and East Forks of Walker Branch Watershed (WBW). The long-term Walker Branch stream chemistry monitoring is intended to provide data on watershed output of chemicals via streamflow and long-term changes in stream chemical composition.
