Plum Island Ecosystems site, station NADP Station MA13, East, MA, study of sulfate in wet deposition in units of kilogramsPerHectare on a monthly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Plum Island Ecosystems (PIE) contains sulfate in wet deposition measurements in kilogramsPerHectare units and were aggregated to a monthly timescale.

Nitrous oxide dataset for East Qinghai-Tibet Plateau waterways

This dataset is a collation of 3-year direct measurement values of N2O concentrations and fluxes for East Qinghai-Tibet Plateau (EQTP) streams and rivers, along with information on location, hydrological, physical, and chemical conditions of the study sites. Given the rarity and high value of this EQTP data set, it will be very valuable for the next update to global riverine N2O flux estimates.

Bartley Stream East stream gauge measurements

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the glacial meltwater streams in that region. These tables contain data pertaining to continuous monitored water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the hydrology of the East Bartley Stream, (Discharge rate, etc) for the 1984-85 season.

Aboveground net primary productivity data for saddle, south of saddle, and east of Tvan, 1982 - ongoing.

Total aboveground biomass samples were collected as part of several studies conducted on Niwot Ridge between 1982 and 2011 and were combined into a single data set that contains the name of the original investigator who collected the data, the URL of the data offered on the Niwot Ridge website, the vegetation type, location, plot ID, subsample ID, plot type, size (if known), year sample was collected, and live vascular aboveground biomass. Contributing investigators were Marilyn Walker, Bill Bowman, Tim Seastedt, Katie Suding, and Hope Humphries. NOTE: This LTER data portal display does not contain important maintenance/log information. Please be sure to view the EML file (a text file that contains XML tags) which is included in the zip archive (click on "Download zip archive") for legacy maintenance/log information pertaining to each dataset.

Aboveground plant biomass for east of T-van, 1998 - 2004.

These data were used in the following related publication: Bowman, William D., Gartner, Julia R., Holland, Keri, and Wiedermann, Magdalena. 2006. Nitrogen critical loads for alpine vegetation and terrestrial ecosystem response - Are we there yet? Ecological Applications 16:1183-1193. doi: 10.1890/1051-0761(2006)016[1183:NCLFAV]2.0.CO;2 Increases in the deposition of anthropogenic nitrogen (N) have been linked to several terrestrial ecological changes, including soil biogeochemistry, plant stress susceptibility, and community diversity. Recognizing the need to identify sensitive indicators of biotic response to N deposition, we empirically estimated the N critical load for changes in alpine plant community composition and compared this with the estimated critical load for soil indicators of ecological change. We also measured the degree to which alpine vegetation may serve as a sink for anthropogenic N and how much plant sequestration is related to changes in species composition. We addressed these research goals by adding 20, 40, or 60 kg N.ha-1yr-1, along with an ambient control (6 kg N ha-1 yr-1 total deposition), to a species rich alpine dry meadow for an eight-year period. Change in plant species composition associated with the treatments occurred within three years of the initiation of the experiment and were significant at all levels of N addition. Using individual species abundance changes and ordination scores, we estimated the N critical loads (total deposition) for (1) change in individual species to be 4 kg N ha-1 yr-1 and (2) for overall community change to be 10 kg N ha-1 yr-1. In contrast, increases in NO3 leaching, soil solution inorganic NO3, and net N nitrification occurred at levels above 20 kg N ha-1 yr-1. Increases in total aboveground biomass were modest and transient, occurring in only one of the three years measured. Vegetative uptake of N increased significantly, primarily as a result of increasing tissue N concentrations and biomass increase
