Abstract

The project described here seeks to answer questions regarding the role increased nitrogen (N) deposition is playing in enhanced carbon (C) sequestration in temperate mid-latitude forests, using detailed measurements from an AmeriFlux tower in southern Indiana (Morgan-Monroe State Forest, or MMSF). The measurements indicate an average atmosphere-surface N flux of approximately 6 mg-N m ^-2 day ^-1 during the 2000 growing season, with approximately 40% coming from dry deposition of ammonia (NH ₃ ), nitric acid (HNO ₃ ), and particle-bound N. Wet deposition and throughfall measurements indicate significant canopy uptake of N (particularly NH ₄ +) at the site, leading to a net canopy exchange (NCE) of –6 kg-N ha ^-1 for the growing season. These data are used in combination with data on the aboveground C:N ratio, litterfall flux, and soil net N mineralization rates to indicate the level of potential perturbation of C sequestration at this site.

Ecosystem-Atmosphere Exchange of Carbon, Water and Energy over a Mixed Deciduous Forest in the Midwest

Technical Report Dragoni, Danilo ; Schmid, Hans Peter ; Grimmond, C S.B. ; ...

During the project period we continued to conduct long-term (multi-year) measurements, analysis, and modeling of energy and mass exchange in and over a deciduous forest in the Midwestern United States, to enhance the understanding of soil-vegetation-atmosphere exchange of carbon. At the time when this report was prepared, results from nine years of measurements (1998 - 2006) of above canopy CO2 and energy fluxes at the AmeriFlux site in the Morgan-Monroe State Forest, Indiana, USA (see Table 1), were available on the Fluxnet database, and the hourly CO2 fluxes for 2007 are presented here (see Figure 1).

Sulfur deposition and cycling in two forests of the Georgia Piedmont

Conference Cappellato, R - Bulletin of the Ecological Society of America; (United States)

Because of the increase in SO[sub 2] emissions in Georgia since the late 70's, a study was undertaken in adjacent deciduous and coniferous forests to estimate the atmospheric input and above-ground cycling of sulfur. During this study, which was conducted in 1988-89, total annual sulfur input to these forests was 17 kg/ha, which was comparable to sulfur inputs to other sites in the eastern United States. Dry deposition accounted for more than 50% of the total atmospheric sulfur input, and SO[sub 2] was the major source of dry deposition of the canopy. Net flux of sulfur in (throughfall flux minusmore »« less
Acid deposition interactions with a regenerating southern Appalachian forest canopy at the Coweeta Hydrologic Laboratory

Thesis/Dissertation Potter, C S

Incident precipitation, throughfall, and stemflow were collected during twenty storm events to examine the importance of factors potentially determining net canopy fluxes, and to quantify canopy exchange and dry deposition rates in a regenerating southern Appalachian forest. Net throughfall fluxes showed consistent canopy effects on rainfall chemistry, with SO/sub 4//sup 2 -/, PO/sub 4//sup 3 -/, Cl/sup -/, K/sup +/, Ca/sup 2 +/, and Mg/sup 2 +/ added to rainfall by foliage, and absorption of NO/sub 3//sup -/-N, and H/sup +/ ions from precipitation. Storm characteristics accounted for the largest portion of the variability in growing seasons net throughfall fluxes,more »« less
Partitioning CO₂ fluxes with isotopologue measurements and modeling to understand mechanisms of forest carbon sequestration

Technical Report Saleska, Scott ; Davidson, Eric ; Finzi, Adrien ; ...

1. Objectives This project combines automated in situ observations of the isotopologues of CO₂ with root observations, novel experimental manipulations of belowground processes, and isotope-enabled ecosystem modeling to investigate mechanisms of below- vs. aboveground carbon sequestration at the Harvard Forest Environmental Measurements Site (EMS). The proposed objectives, which have now been largely accomplished, include: A. Partitioning of net ecosystem CO₂ exchange (NEE) into photosynthesis and respiration using long-term continuous observations of the isotopic composition of NEE, and analysis of their dynamics ; B. Investigation of the influence of vegetation phenology on the timing and magnitude of carbon allocated belowground usingmore »« less

Atmospheric sulfur deposition, neutralization, and ion leaching in two deciduous forest ecosystems

Journal Article Richter, D D ; Johnson, D W ; Todd, D E

In the 1981 water year, bulk precipitation was primarily a solution of dilute H/sub 2/SO/sub 4/, and SO/sub 4//sup 2 -/ was the dominant anion in throughfall and soil leachates in two eastern Tennessee deciduous forests. Ecosystem inputs of SO/sub 4//sup 2 -/, which included dry deposition of forest canopies, many have been up to 40% greater than input estimates based on atmospheric deposition sampling in open areas. Volume-weighted mean annual pH of bulk precipitation was 4.3; of throughfall 4.8; and of leachates from O2, A1, and B21 soil horizons about 6.0. At both sites, strong acids in precipitation weremore »« less
