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 »
Goals and Background. Engagement of arts and humanities in LTER programs has grown substantially over the past few years, to the point where now more than half of the LTER sites have operating or planned programs. This emergence has been the source of much excitement within and outside of the LTER Network. Four sites have… Read more »
The Objectives of the effort is to: (1) Assess our new generalized metacommunity model (Fig 1b), which is based on previous work (Sokol et al. 2011), and provides a mechanism to use the axes that define metacommunity state space (Fig 1a) to predict metacommunity diversity. We will use data packages from the LTER NIS to… Read more »
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 »
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 »
Goals. We propose to synthesize data on saltmarsh production from 3 LTER sites and 4 additional sites to generate a comprehensive understanding of the factors driving variation in salt marsh primary production, and how these factors vary geographically.
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 »
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 »
