As photosynthesis on Earth produces the primary signatures of life that can be detected
astronomically at the global scale, a strong focus of the search for extrasolar life will be …

The sustainable use and management of important tropical coastal ecosystems (mangrove
forests, seagrass beds and coral reefs) cannot be done without understanding the direct and …

Technical advancements have widened the limits of remote sensing in mapping shallow
water benthic habitats and bathymetry over the last decades. On the other hand, the needs …

A standard algorithm for determining depth in clear water from passive sensors exists; but it
requires tuning of five parameters and does not retrieve depths where the bottom has an …

The carbohydrate polymers known as β-1, 3-d-glucans exert potent effects on the immune
system—stimulating antitumour and antimicrobial activity, for example—by binding to …

The IKONOS 2 satellite was launched in late 1999 and carries the first commercial
multispectral instrument to achieve 4 m spatial resolution. The cost and accuracy of using …

Coral reef benthic communities are mosaics of individual bottom-types that are distinguished
by their taxonomic composition and functional roles in the ecosystem. Knowledge of …

We investigate the abilities of seven remote sensors to classify coral, algae, and carbonate
sand based on 10,632 reflectance spectra measured in situ on reefs around the world …

The spectral signatures of the seagrasses Zostera capricorni, Posidonia australis, and
Halophila ovalis were investigated to determine whether species could be discriminated by …

Les performances des capteurs satellites Landsat-7 ETM+, ASTER, SPOT-HRV et Ikonos
ainsi que le capteur aéroporté MASTER (instrument de simulation de MODIS‐ASTER) ont …
