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. This dataset contains 5 data files in comma-separate (*.csv) format.

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.

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
