Phytoplankton blooms are usually dominated by chain-forming diatom species that can alter food pathways from primary producers to predators by reducing the interactions between intermediate trophic levels. The food-web modifications are determined by

Over the past decade Surface Plasmon Resonance (SPR) techniques have been applied to the measurement of numerous analytes. In this article, an SPR biosensor system deployed from an oceanographic vessel was used to measure dissolved domoic acid (DA),

In this paper we present the ZooCAM, a system designed to digitize and analyse on board large volume samples of preserved and living metazooplankton (i.e. multicellular zooplankton) and fish eggs >300 µm ESD. The ZooCAM has been specifically designe

Recent advances in laser and video technologies have enabled single particles to be visualized in aqueous solution. Here, we describe a new instrument enabling the analysis of the fluorescence signatures of marine particles directly in seawater: the

A nautical drone was designed for the monitoring of estuarine and coastal waters in the context of the Water Framework Directive (WFD) to : - go up to 500 m off the coastline in less than 5 minutes, - perform in situ measurements (temperature, salini

During July 2006, a cruise was carried out in the Northern Bay of Biscay (off Brittany, France) to study meso- and microscale patterns of phytoplankton distribution. Moderate concentrations (102–103 cells L−1) of Dinophysis acuminata were constra

Sediment transport processes at the sediment-water interface are usually studied using flume tests. Due to technical limitations, extreme hydro-sedimentary conditions are then rarely considered. Sediment profile imaging (SPI) is a widely used techniq

Seasonal variations in nutrient inputs are described for the main rivers (Loire and Vilaine) flowing into the northern Bay of Biscay. The river plumes are high in N/P ratio in late winter and spring, but not in the inner plume during the summer. Cons

A design for a new underwater video-system to detect and observe suspended particles is presented. Particles are collected and isolated in a rectangular box where they are highly illuminated by a white light plane. The total field of view is determin
