B51G:
Remote Sensing of Northern High-Latitude Ecosystem and Landscape Change Posters


Session ID#: 8785

Session Description:
Terrestrial and aquatic ecosystems across the northern high-latitudes are undergoing rapid, extensive and unprecedented changes in their nature, structure and function. Remote sensing is a critical tool for monitoring these changes, providing key data and techniques for scaling in situ measurements, parameterizing and evaluating mechanistic models, and testing hypotheses on dynamic ecological and landscape processes. This session seeks contributions describing the state-of-the-art in new data collections and analysis to quantify and characterize climate- and disturbance- driven change indicators across arctic and boreal landscapes. We invite contributions that use remote sensing information from multi-scale platforms, i.e. ground, aircraft and satellites, to observe and quantify these dynamics and contribute to an improved understanding of the drivers and consequences of ecosystem and landscape change. Contributions that demonstrate the use of remote sensing data products in modeling and decision support and/or the challenges and future opportunities for remote sensing in high latitudes are encouraged.
