Hidden becomes clear: Optical remote sensing of vegetation reveals water table dynamics in northern peatlands

Depth Estimation of Submerged Aquatic Vegetation in Clear Water Streams Using Low-Altitude Optical Remote Sensing

UAVs and other low-altitude remote sensing platforms are proving very useful tools for remote sensing of river systems. Currently consumer grade cameras are still the most commonly used sensors for this purpose. In particular, progress is being made to obtain river bathymetry from the optical image data collected with such cameras, using the strong attenuation of light in water. No studies have...

Potential for using remote sensing to estimate carbon fluxes across northern peatlands - A review.

Peatlands store large amounts of terrestrial carbon and any changes to their carbon balance could cause large changes in the greenhouse gas (GHG) balance of the Earth's atmosphere. There is still much uncertainty about how the GHG dynamics of peatlands are affected by climate and land use change. Current field-based methods of estimating annual carbon exchange between peatlands and the atmosphe...

Water quality estimation by optical remote sensing in boreal lakes

LiDAR Remote Sensing of Vegetation Biomass

Accurate estimates of vegetation biomass are critical for calibrating and validating biogeochemical models (Hurtt et al. 2010), quantifying carbon fluxes from land use and land cover change (Shukla et al. 1990; Houghton et al. 2001), and supporting the United Nations Framework Convention on Climate Change (UNFCCC) program to reduce deforestation and forest degradation (Reducing Emissions from D...

Remote sensing of vegetation water content from equivalent water thickness using satellite imagery

Vegetation water content (VWC) is one of the most important parameters for the successful retrieval of soil moisture content from microwave data. Normalized Difference Infrared Index (NDII) is a widely-used index to remotely sense Equivalent Water Thickness (EWT) of leaves and canopies; however, the amount of water in the foliage is a small part of total VWC. Sites of corn (Zea mays), soybean (...
