The contribution of hyperspectral remote sensing to identify vegetation characteristics necessary to assess the fate of Persistent Organic Pollutants (POPs) in the environment
hyperspectral imaging species distribution LAI semi-empirical model POPs
2015/9/7
During recent years hyperspectral remote sensing data were successfully used to characterise the state and properties of vegetation. The information on vegetation cover and status is useful for a rang...

Biological communities are changing drastically in response to global climate change (Walther et al., 2002), changes in use by human populations (Krishtalka et al., 2002), and introduction of exotic s...
Sensitivity Analysis of Spectral Indices to Ozone Absorption Using Physical Simulations in a Forest Environment: Comparative Study between MODIS, SPOT VéGéTATION & AVHRR
Spectral Indices Ozone Absorption Using Physical Simulations
2015/7/29
Considering a forest cover (Balsam Fir with various densities) we analyze the sensitivity of several vegetation indices to
ozone absorption using physical simulations in the spectral bands of MODIS,...
The Machine in Neptune's Garden: Historical Perspectives on Technology and the Marine Environment
Historical Perspectives Technology and the Marine Environment
2015/7/29
One measure of our science's maturity is that there are now a small but growing number of historians of science specializing in oceanography. In the United States, they meet periodically at Maury conf...

2015/7/22
When their previous book Seabed Pockmarks and Seepages was published in 1988, Martin Hovland and Alan Judd were the first authors to illustrate and discuss global geological, geophysical, chemical, an...
Forecasting the Ocean's Optical Environment Using the BioCast System
Ocean's Optical Environment BioCast System
2015/7/20
The Bio-Optical Forecasting (BioCast) system is a model that provides the US Navy with short-term forecasts of the ocean's optical environment. The forecasts are required to support a broad spectrum o...
