Atmospheric correction to LTER Landsat catalog

Goals: The goal of this project is to build on the previously funded work of Kyle Cavanaugh to complete the atmospheric corrections to the LTER Landsat catalog. Atmospheric corrections are required before any higher level data products (e.g. maps of land cover change, biomass, NDVI) can be created. The corrected scenes can then be used… Read more »

Cross site analysis and synthesis of the role of vegetation, sediment supply, sea level rise and storminess on intertidal coastal geomorphology

Summary: Intertidal coastal environments are prone to changes induced by sea level rise, increase in storminess, and anthropogenic disturbances. It is unclear how changes in external drivers may affect the dynamics of low energy coastal environments because there are multiple evidences that their response might be non-linear, with thresholds and discontinuities. Process based modeling of… Read more »

Establishing High Quality Digital Collections of LTER Educational Resources

An LTER Educational Digital Library (LEDL) is an unprecedented, high-quality collection of educational learning resources centrally located on the LTER Education website. It includes instructional materials, educational data sets, multimedia, and visualizations serving middle, high school and undergraduate classrooms and educational professionals. Its underlying purpose is to support the teaching and learning of ecological science… Read more »

Development and analysis of a database of Landsat Thematic Mapper imagery to support cross-site research

Goals and ObjectivesWe propose to generate a cross-site database of existing Landsat TM satellite imagery covering each of the 26 current sites in the LTER network from 1985-present.  We will then collaborate with researchers from a subset of sites to create higher-level cross-site data products including atmospherically corrected surface reflectance data and time-series maps of… Read more »

Responses of ecosystem productivity to Critical Climate Periods; understanding the role of fine-scale temporal climate patterns on ecosystem productivity

Goals and Hypotheses Based on this conceptual framework and the ability of CCP analyses to improve our understanding of ecosystem processes over annual climate characteristics at KNZ we propose to expand this CCP analysis to all terrestrial LTER sites.  In addition to the site-level understanding of plant production with CCPs, a broader understanding of ecosystem… Read more »
