Amplification and dampening of soil respiration by changes in temperature variability
The acceleration in the release of carbon from soils is one of the most important positive feedbacks related to anthropogenically induced climate change. Analyses studying the mechanisms for soil carbon release through decomposition have focused on the effect of changes in the average temperature, with little attention to changes to its variability.
Inter-LTER collaboration – Chemical characterization of dissolved organic matter (DOM) from headwaters using a multi-analytical approach: Preliminary results from six different Biomes
Dissolved organic matter (DOM) is ubiquitous in a wide range in aquatic environments and plays important ecological roles by fueling the microbial loop, acting as a factor determining light penetration, as the substrate for photoproducts, as a pH buffer, and as a medium for the complexation of trace metals. In addition, DOM fluxes from terrestrial to marine environments have been reported to steadily increase due to climate change and anthropogenic influences. Thus, the chemical characteristics of DOM have extensive implications in aquatic environments.
LTER - National Biological Information Infrastructure
The National Biological Information Infrastructure (NBII) entered in 2004 in a five year cooperative agreement with LTER. The NBII-LTER cooperative agreement is the result of efforts championed by W. Michener dating back to 2000. The overarching goal is the interoperability of both networks: Sharing the wealth on information on ecological and biological resources, and offer those to educators,, scientists, lawmakers and the public in general.
Enabling the LTER Network Information System through the Provenance Aware Synthesis Tracking Architecture
The LTER Network Information System (NIS) is the primary channel for exposing site-based data and metadata through a unified interface for use by value-added applications that include synthesis projects at both local and national scales, and is a core component of the Strategic Cyberinfrastructure Plan. The underlying framework to enable the LTER NIS is the Provenance Aware Synthesis Tracking Architecture (PASTA).
Ensuring the Long-term Preservation and Integrity of Earth Observation Data through DataONE
DataONE (Observation Network Earth) ensures the preservation and access to earth observation data spanning broad science disciplines to enable advances in science and education. For example, data on the sources and sinks of greenhouse gases can facilitate advances in climate change science and modeling, while data on land use patterns can facilitate scientific understanding of human-environment interactions at local and regional scales.

Remote Sensing Activities of the LTER Network
The LTER Network uses Remote Sensing and Geographic Information System technologies extensively in its research activities. The focus for remote sensing and GIS activities at LNO is for data acquisition and the cross-site, large-scale collaborations which are afforded by these data.
