Última Étude par acoustique large bande de la composition et de la distribution spatiale de couches diffusantes denses dans le golfe de Gascogne ArchiMer Blanluet, Arthur. Intermediate trophic components of pelagic ecosystem (from mesozooplakton to micronekton) funnel energy and organic matters from primary producers to many commercial species (anchovy, sardines…). Some of these organisms are supposed to be important contributors to the ubiquitous Sound Scattering Layers (SSLs) observed over a broad range of spatio-temporal scales and geographical areas. Yet, the SSLs taxonomic composition remains largely unknown. The aim of this PhD was to describe the composition and repartition of dense SSLs observed in the Bay of Biscay (France) in spring at several spatial scales, using broadband acoustics, nets and videos. In the first chapter, we showed that the echo sounder beam widths had few effect on the SSLs backscatter,...

Nishiyama,Eric Y.; Araujo,Enilma M.; Oliveira,Otto M.P.. ABSTRACT The siphonophores of the Brazilian coast are poorly studied, despite their abundance and ecological importance. Lensia is the most diverse genus within Siphonophora, with twenty-six valid species. A total of twenty species of Lensia are recorded for South American marine waters. This study presents morphological descriptions and an identification key to the species of Lensia that were collected in two oceanographic campaigns throughout the southeastern Brazilian coast. A total of sixty-one specimens were photographed, described, schematized and measured, and fifteen species of Lensia were identified.

BACKGROUND: Despite their ecological, economic and medical relevance, very little information is available on the distribution of planktonic cnidarians, this being particularly true for some regions of the ocean such as the Gulf of Mexico. In fact, the effect of locally important oceanographic features such as the offshore autumnal transport on the distribution of planktonic cnidarians has long been overlooked in this region. Because of this, the present study aimed to analyse the spatial patterns of planktonic cnidarian assemblages in the southern Gulf of Mexico during the autumn of 1998, when particularly intense conditions of convergence, offshore water transportation and productivity were recorded. The assemblages were described in terms of their... Tipo: Journal article Palavras-chave: Campeche Bay; Gelatinous zooplankton; Medusae; Siphonophores; Surface circulation.
