Abstract. The SEMAPHORE (Structure des Echanges Mer-Atmosphère, Propriétés Hétérogénéités Océaniques: Recherche Expérimentale) experiment has been conducted from June to November 1993 in the Northeast Atlantic between Azores and Madeira. It was centered on study of mesoscale ocean circulation air-sea interactions. experimental investigation achieved at using moorings, floats, ship hydrological survey, a smaller scale by one dedicated ship, two instrumented aircraft, surface drifting buoys,...
Abstract This work is the first study exploiting along track altimetry data to observe and monitor coastal ocean features over transition area between western eastern Mediterranean Basins. The relative performances of both AVISO X‐TRACK research regional altimetric sets are compared using in situ observations. Both products cross validated with tide gauge records. altimeter‐derived geostrophic velocities also observations from a moored Acoustic Doppler Current Profiler. Results indicate good...
The life cycle of Calanus finmarchicus in the lower St. Lawrence estuary is described based on observations female egg production rate, population stage abundance, and chlorophyll a biomass collected over 7 years (19911997) at centrally located monitoring station. mean seasonal pattern shows maximum abundance females May, but peak rate naupliar (N3N6) occur early July just after onset late spring summer phytoplankton bloom. structure characterized by low copepodite stages C1C3 high C5...

The Gulf of St. Lawrence (Canada) is a subarctic marginal sea characterized by highly variable hydrodynamic conditions that generate spatial heterogeneity in the marine production.

Abstract. Technological advances in the recent satellite altimeter missions of Jason-2, SARAL/AltiKa and CryoSat-2 have improved their signal-to-noise ratio, allowing us to observe finer-scale ocean processes with along-track data. Here, we analyse noise levels observable scales northwestern Mediterranean Sea, using spectral analyses sea surface height from three missions. Jason-2 has a higher mean level strong seasonal variations, winter due rougher state. lowest noise, again variations. is...
Abstract. The Arctic Ocean (AO) undergoes profound changes of its physical and biotic environments due to climate change. In some areas the Beaufort Sea, stronger haline stratification observed in summer alters plankton ecosystem structure, functioning productivity, promoting oligotrophy. A one-dimension (1-D) physical–biological coupled model based on large multiparametric database Malina project Sea was used (i) infer related nitrogen fluxes (ii) assess sensitivity key light-driven...
Abstract. During the last 15 years, substantial progress has been achieved in altimetry data processing, now providing with enough accuracy to illustrate potential of these observations for coastal applications. In parallel, new techniques improve quality by reducing land contamination and enhancing signal-to-noise ratio. Satellite provides more robust accurate measurements ever closer coast resolve shorter ocean signals. An important issue is learn how use conjunction other observing...

Primary production, the basic component of food web and a sink for dissolved inorganic carbon, is major unknown in Arctic seas, particularly ice algal which detailed comprehensive studies are often limited space time. We present here simple alga model its coupling with regional 3D ice–ocean Hudson Bay system (HBS), including Strait Foxe Basin, as first attempt to estimate production potential contribution pelagic ecosystem on scale.

Upward motions are often invoked to explain the high productivity of permanent geostrophic fronts in Western Mediterranean while physical evidence such upward advections is seldom reported. The goal this study define biological and chemical criteria, which can be used localize zones. We use a one‐dimensional, time‐dependent model phytoplankton dynamics test effects advection on vertical distribution biomass, nutrients, dissolved oxygen.

Abstract Cape Verde is a tropical oceanic ecosystem, highly fragmented and dispersed, with islands physically isolated by distance depth. To understand how isolation affects the ecological variability in this archipelago, we conducted research project on community structure of 18 commercially most important demersal fishes. An index based species relative dominance (D i ) developed from Catch Per Unit Effort, derived an extensive database artisanal fisheries. Two measures between are...
