Optical properties of the “clearest” natural waters
Optical measurements within both the visible and near ultraviolet (UV) parts of the spectrum (305–750 nm) were recently made in hyperoligotrophic waters in the South Pacific gyre (near Easter… Expand
Examining the consistency of products derived from various ocean color sensors in open ocean (Case 1) waters in the perspective of a multi-sensor approach
During its lifetime, a space-borne ocean color sensor provides world-wide information about important biogeochemical properties of the upper ocean every 2 to 4 days in cloudless regions. Merging… Expand
Diffuse reflectance of oceanic shallow waters: influence of water depth and bottom albedo
We used simplifying assumptions to derive analytical formulae expressing the reflectance of shallow waters as a function of observation depth and of bottom depth and albedo. These formulae also… Expand
Diffuse reflectance of oceanic waters. III. Implication of bidirectionality for the remote-sensing problem.
The upwelling radiance field beneath the ocean surface and the emerging radiance field are not generally isotropic. Their bidirectional structure depends on the illumination conditions (the Sun's… Expand
Bidirectional reflectance of oceanic waters: accounting for Raman emission and varying particle scattering phase function.
The bidirectionality of the upward radiance field in oceanic case 1 waters has been reinvestigated by incorporation of revised parameterizations of inherent optical properties as a function of the… Expand
Diffuse reflectance of oceanic waters. II Bidirectional aspects.
For visible wavelengths and for most of the oceanic waters, the albedo for single scattering (?) is not high enough to generate within the upper layers of the ocean a completely diffuse regime, so… Expand
Functioning of the Mediterranean Sea: past and present changes related to freshwater input and climate changes
Abstract Mediterranean functioning is linked to continental climate and more particularly to freshwater budget across its surface. In the sediment of the eastern basin, the sapropel layers are… Expand
A comparison of global estimates of marine primary production from ocean color
Abstract The third primary production algorithm round robin (PPARR3) compares output from 24 models that estimate depth-integrated primary production from satellite measurements of ocean color, as… Expand
Light availability in the coastal ocean: Impact on the distribution of benthic photosynthetic organisms and their contribution to primary production
One of the major features of the coastal zone is that part of its sea floor receives a significant amount of sun- light and can therefore sustain benthic primary production by seagrasses, macroalgae,… Expand
Assessment of uncertainty in the ocean reflectance determined by three satellite ocean color sensors (MERIS, SeaWiFS and MODIS-A) at an offshore site in the Mediterranean Sea (BOUSSOLE project)
 The match-up of satellite-derived reflectances with in situ observations is crucial to evaluate their quality and temporal stability. To contribute to this effort, a project has been set up to… Expand
