a r t i c l e i n f o Keywords: Chlorophyll-a Normalized difference chlorophyll index Remote sensing reflectance Spectral algorithm Turbid productive waters MEdium Resolution Imaging Spectrometer We propose a normalized difference chlorophyll index (NDCI) to predict chlorophyll-a (chl-a) concentration from remote sensing data in estuarine and coastal turbid productive (case 2) waters. NDCI cali...

Nitrogen-limited csluaries, shallow coastal waters, and continental shelf ivatcrs cover only 15% of the world’s ocean area, but account for nearly half the global oceanic primary production. This disproportionality is partly attributed to accelerating and geographically expanding anthropogenic N h-lading and eutrophication. Among accelerating N inputs, atmospheric deposition (AD) (as wetand dry...

A review of previous studies on Kemp's ridley sea turtle (Lepidochelys kempii) diet was combined with information on the diet of the species in the coastal waters of New York State. Juvenile Kemp's ridleys occupy coastal Long Island, New York waters during the summer and early autumn months. Both fecal and intestinal samples collected between 1985 and 1989 were analyzed to obtain information on...

This paper is part of a work program concerning the modeling of object drift in near coastal ocean waters over a several week time period. The final target of this program is to develop methods to forecast the drift of things like containers, lost objects or oil spill over long periods of time in near coastal ocean areas. Such methods would be of interest for services in charge of maritime safe...

MERIS imageries over coastal waters around the United States were ordered from ESA. These data either reveal enormous phytoplankton blooms (chlorophyll concentrations in the range of 100 – 1000 mg/m) or turbid river plume waters or optically shallow environments. We used in situ measurements to validate remote-sensing reflectance derived from MERIS. Further, we applied algorithms designed for o...

The status report on metal pollution in tropical estuaries and coastal waters is important to understand potential environmental health hazards. Detailed baseline measurements were made on physicochemical parameters (pH, temperature, redox potential, electrical conductivity, salinity, dissolved oxygen, total dissolved solid), major ions (Na, Ca, Mg, K, HCO3, Cl, SO4 and NO3) and metals concentr...

The gap between airborne imaging spectroscopy and traditional multi spectral satellite sensors is decreasing thanks to a new generation of satellite sensors of which CHRIS mounted on the small and low-cost PROBA satellite is the prototype. Although image acquisition and analysis are still in a test phase, the high spatial and spectral resolution and pointability have proved their potential. Bec...
