The developments of subsea observatories has been addressed by several national and European projects involving Ifremer engineering teams during the last decade. The motivation of scientific research disciplines has been growing during the same period. The coordination of ESONET Network of Excellence has been a unique occasion to analyse the best practices world wide and propose standards and recommendations...
Dissolved nutrient dynamics broadly affect issues related to public health, ecosystem status and resource sustainability. Modeling ecosystem dynamics and predicting changes in normal variability due to potentially adverse impacts requires sustained and accurate information on nutrient availability. On site sampling is often resource limited which results in sparse data sets with low temporal and spatial...
Self-contained, moored echo sounders are a means of monitoring the behavior of populations of zooplankton and small fish over extended periods of time. Such instruments, either moored at or near the seafloor looking upward, or mounted on a surface buoy looking downward, record profiles of acoustic backscatter as a time series, and thus can provide insights into the long-term behavior and distribution...
Atmospheric correction of Hyperion imagery over aquatic environments is generally more demanding than over land because the signal from the water column is small. In this paper, an atmospheric correction algorithm designed for the Hyperion hyper spectral imagery based on the analysis of the atmospheric correction algorithm of FLAASH and the algorithm adopted by MODIS imagery. It makes use of band...
