Abstract: 

The seasonal variability in rainfall duration, intensity, and volume due to the North American Monsoon Season (NAMS) has been well documented in southwestern American semiarid landscapes.  The char

acteristic high intensity convective NAMS storm systems during the months of June-September lead to a greatly altered land surface in terms of soil moisture and vegetation.  However, large-scale investigation of the effects of land-surface changes on hydrometeorological processes within the NAMS region has minimal associated research to this point.  It is our objective to characterize the Tromble Weir watershed within the Jornada Experimental Range in order to better understand the role of land surface conditions on the propagation of the NAMS. In particular, this study investigates the impact of land-surface heterogeneity on eddy covariance tower measurements. We rely on the use of an eddy covariance tower present at the Tromble Weir watershed as well as a series of soil moisture and temperature probes under various land surface conditions distributed in the area near the tower. This study will assess and improve the implementation of the eddy covariance technique in heterogeneous landscapes like those at the Jornada Experimental Range.

This research includes 3 hydrometeorological stations, 3 H-flumes with pressure transducers, and one meteorological flux tower.  Hillslope transects are run from each of the hydrometeorological stations in order to assess local spatial variations in soil moisture and temperature.  The equipment deployments utilized in this study will allow for watershed scale characterization of soil energy flux, rainfall, soil moisture, and streamflow, and how feedbacks between these parameters and seasonal land cover changes in vegetation are affected by NAMS hydrometeorological processes.  This study is the first of a multi-year watershed characterization project which will include 3 separate watersheds1 over 5 consecutive summers.  The deployment of this dense observation network in multiple semi-arid basins will allow for cross-NAMS region comparisons of hydrometeorological responses to the seasonal evolution of land-cover changes through the application of a coupled hydrometeorological modeling system.  It will also allow for the forecasting of how land-surface may change the hydrometeorological responses of basins within the NAMS region.

1We will be focusing on primarily three sites: at the Jornada, at the Santa Rita Experimental Range in southern Arizona, and at the Sevilleta National Wildlife Refuge in southern New Mexico.

This summary dataset contains the following columns for the shrub plots: Plot: the identification number for the 6 grassland plots.

Abstract: 

This data set was collected to provide data for comparison of the losses of dissolved nitrogen and phosphorus in the runoff from grass- and shrub- dominated plots in the Jornada Basin of southern New Mexico. This dataset contains the following columns: Plot: the identification number for the plots, which are grouped for grass, shrub or intershrub areas.

Fill Time: the time in seconds used to collect an individual sample of discharge from the plot. Time: the time in minutes (from the beginning of the rainfall simulation) at which each individual collection of discharge began. In each case, the first time listed is the time at which discharge was first observed. Time b/w samples: the time in seconds between the beginning the collection of a given sample of discharge and the beginning of the next collection. Q: the rate of discharge during each collection, in cubic centimeters per second. AveQ/time: the total discharge during an interval in cubic centimeters. For example, the discharge between 16 and 20 minutes is calculated as the mean of the discharge at l6 and 20 minutes multiplied by 4 minutes. InorgN-rain (adjusted inorganic N): the concentration of NH4-N + NO3-N in the discharge sample collected, corrected for the sum of the concentration of these ions in the simulated rainfall applied. Concentration is given in milligrams per liter for N contained in the sum of these forms. Analysis for NH4-N and NO3-N was performed using the Bran-Luebbe Traacs 800 Autoanalyzer, as detailed in Schlesinger et al. (l999). Total N-rain (adjusted total N): the concentration of total dissolved N in the discharge sample collected, corrected for the concentration of total dissolved N in the simulated rainfall applied. Concentration is given in milligrams per liter of total dissolved N in the sample. The concentration of total dissolved N was performed using the Traacs 800 Autoanalyzer, following a persulfate digestion of the sample, as detailed in Schlesinger et al. (l999). OrgN-rain (adjusted organic N): the concentration of N contained in dissolved organic forms, corrected for the concentration of dissolved organic N in the simulated rainfall applied. Dissolved organic N is calculated as the difference, in any sample, between the total dissolved N and the sum of NH4-N and NO3-N. Values are in milligrams per liter. Total P-rain (adjusted total P): the concentration of total dissolved phosphorus, corrected for the concentration of total dissolved phosphorus in the simulated rainfall applied, both in milligrams per liter. Org-P-rain (adjusted org P): the concentration of dissolved organic phosphorus, corrected for the concentration of dissolved organic phosphorus in the simulated rainfall applied, both in milligrams per liter. Inorg-N-rain (adjusted inorganic N), the yield in grams of NH4-N plus NO3-N in the discharge collected. TotalN-rain (adjusted total N), the yield in grams of total dissolved N in the discharge collected. OrgN-rain (adjusted organic N), the yield in grams of forms of dissolved organic N in the discharge collected. Total P-rain (adjusted total P), the yield in grams of total dissolved phosphorus in the discharge collected. OrgP-rain (adjusted organic P), the yield in grams of forms of dissolved organic phosphorus in the discharge collected. InorgN-rain (adjusted inorganic N) load, is the rate of loss, in grams per second, of the sum of NH4-N plus NO3-N during the period of the sample collection. Total N-rain (adjusted total N) load, is the rate of loss, in grams per second, of total dissolved N during the period of the sample collection. OrgN-rain (adjusted organic N) load, is the rate of loss, in grams per second, of dissolved organic N during the period of the sample collection. Total P-rain (adjusted total P) load, is the rate of loss, in grams per second, of total dissolved P during the period of the sample collection. Org-P-rain (adjusted organic P) load, is the rate of loss, in grams per second, of dissolved organic P during the period of the sample collection.

Abstract: 

Rainfall simulation experiments were performed in aras of semiarid grassland (Boutelous eriopoda) and arid shrubland (Larrea tridentata).

The objective was to compare the runoff of nitrogen (N) and phosphorus (P) from these habitats to assess whether losses of soil nutrients are associated with the invasion of grasslands by shrubs.

Abstract: 

Looking at infiltration and runoff rates as related to rain event duration and intensity as well as soil and organic movement as related below in creosotebush and grassland areas.

Nine hydrology runoff plots were begun in 1983 during LTER-I and located in creosotebush zone. An additional 12 runoff plots have been added. These additions consist of 4 each at C-CALI, G-SUMM, and G-IBPE. G-SUMM and G-IBPE are blackgrama grassland sites. Refer to LTER site map for locations. Water runoff was collected from individual natural rain events off 2x2m plots. C-TERM consists of 8 plots. Plots C1-C4 are untreated. Plots T1-T5 were previously treated with chlordane to remove termites. Each of the 4 sets of run off plots at all sites can be divided into 2 low cover and 2 high cover plots (for creosotebush zone, these are with and without creosotebush shrubs). Data collected: relative cover, runoff, suspended sediment, precipitation, deposited sediment, percent carbon of deposited sample, water chemistry.

Abstract: 

This dataset quantities dissolved nutrients in water surface runoff from natural rainfall events at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental

This dataset quantities dissolved nutrients in water surface runoff from natural rainfall events at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental Range. Chemical analyses include F, Cl, NO3, SO4 by ion chromatography, NH4 by autoanalyzer, Ca, Mg, Na, K by atomic absorption spectrophotometry, and total N and P by auto- analyzer.  Nutrient losses from shrubland plots were greater than from grassland plots. The greater nutrient losses in shrublands were due to higher runoff, rather than higher nutrient concentrations in runoff. This study is complete. Refer to:
