Última Seismic reflection imaging of shallow oceanographic structures ArchiMer Piete, Helene; Marie, Louis; Marsset, Bruno; Thomas, Yannick; Gutscher, Marc-andre. Multichannel seismic (MCS) reflection profiling can provide high lateral resolution images of deep ocean thermohaline fine structure. However, the shallowest layers of the water column (z < 150 m) have remained unexplored by this technique until recently. In order to explore the feasibility of shallow seismic oceanography (SO), we reprocessed and analyzed four multichannel seismic reflection sections featuring reflectors at depths between 10 and 150 m. The influence of the acquisition parameters was quantified. Seismic data processing dedicated to SO was also investigated. Conventional seismic acquisition systems were found to be ill-suited to the imaging of shallow oceanographic structures, because of a high antenna filter effect induced by large...

Distribución, abundancia y variación estacional del fitoplancton en relación a factores físico-químicos y la dinámica hidrológica. OceanDocs Akselman, R.. This study was based on four seasonal cruises during 1984 and 1985. It revealed a thermo-haline frontal system formed by the advection of the Coastal Water mass flowing in two branches, one running towards the coast and the other mid-shelf directed. The thermocline developed between late spring and autumn results in a low inorganic nutrient concentration in the upper layer. Nonetheless in winter, a vertical homogeneity and high nutrient concentration were observed. Phytoplankton development presented a typical temperate-seas annual cycle. In winter, reduced populations were dominated by diatoms. The highest biomass concentration in the cycle coincided with the spring blooming, to which Thalassio sira anguste-lineata,Alexandrium tamarense, Heterocapsa...
