“…The benthic system maintains a significant part of the marine biodiversity for the entire South Atlantic basin and support important breeding and feeding grounds of reef fishes, tuna, shark, turtle, marine mammals and the largest concentration of seabirds in the Western Atlantic [34]. A h ighly diverse benthic community co lonizes the islands slopes [6,7], in Rocas coralline algae is the main atoll's building frame.…”

This paper investigates the dynamics of the deep chlorophyll maximu m layer (DCM L) along the Fernando de Noronha Ridge in the oligotrophic western equatorial Atlantic off northeast Brazil. M ixing processes between water masses above and below the thermocline may occur in a scale of tens of meters around the 24.5 to 25.5 isopycnals, where photoautotrophs are concentrate at the bottom of the euphotic zone. The primary production at the DCM L can provide 210 (±170) metric tons of Carbon per day to the benthic community at the Rocas atoll. The behavior of isopycnals in deeper and strongly stratified waters suggest that internal waves may imp rove primary production, by lift ing the deeper and nutrient-rich South Atlantic Central Water upwards and carrying the autotrophs to brighter depths.

Biota Neotrop. 11(2): http://www.biotaneotropica.org.br/v11n2/en/ abstract?article+bn03711022011Abstract: The Brazilian Navy (DHN/MB) commissioned a series of Oceanographic Operations covering almost the entire inner continental shelf of the country from the 1960s through the 1980s. Surveys provided geological data on the sea bottom and marine biota along the entire Brazilian coast. This report lists data on 15 hydroid species collected during Operations GEOCOSTA RIO I in 1979 and GEOCOSTA RIO II in 1986, at (Vanhöffen, 1910), e Orthopyxis integra (Macgillivray, 1842). A distribuição de três espécies (Aglaophenia rhynchocarpa, Plumularia strobilophora, Clytia paulensis) foi ampliada na costa brasileira rumo ao sul. A distribuição batimétrica de seis espécies (B. vestita, P. strobilophora, C. hincksii, C. paulensis, D. dalmasi, O. integra) também foi ampliada na plataforma continental brasileira.

-(Quantitative structural patterns of Sargassum beds (Phaeophyta, Fucales) of the coasts of Rio de Janeiro and São Paulo states, Brazil). This paper aimed to describe the biological structure of Sargassum beds along the coasts of Rio de Janeiro and São Paulo states. Sixteen rocky shore communities were sampled at random (50 x 50 cm quadrats) during 1991-92. These communities presented populations of distinct Sargassum species. They were chosen because they were subjected to different degrees of wave action and emersion. Seven infrageneric taxa of this genus were studied. The Sargassum dry mass varied from 37 g.m -2 to 587 g.m -2 ; the highest values were found in moderate and protected sites. The cluster analysis of these communities, considering the dry mass of 75 groups of macroalgae and macroinvertebrates, indicated three structural patterns characterized by the most abundant group of organisms: 1) Sargassum, in places not exposed to direct wave action, frequent emersion nor recent disturbances; 2) calcareous algae (Corallinaceae), mainly in exposed places, with Phragmatopoma lapidosa (tube worm) and/ or Perna perna (mussels); 3) other groups of non-calcareous algae, such as Dictyopteris delicatula, representative in intermediate situations. These patterns may be usefull to study the exploitation potentiality of Sargassum and other organisms, like mussels, in the Brazilian coast. ; os maiores valores foram encontrados em locais moderados e protegidos. A análise de agrupamento dessas comunidades, considerando a massa seca de 75 grupos de macroalgas e macroinvertebrados, indicou três padrões estruturais caracterizados pelo grupo de organismos mais abundantes: 1) Sargassum, em locais não expostos à ação direta das ondas, nem à emersão freqüente e distúrbios recentes; 2) algas calcárias (Corallinaceae), principalmente em locais expostos à ação das ondas e à emersão, juntamente com Phragmatopoma lapidosa (poliqueto tubícola) e/ou Perna perna (mexilhão); 3) outros grupos de macroalgas não calcárias, como Dictyopteris delicatula, representativos em situações intermediárias. Esses padrões poderão ser úteis para a avaliação do potencial de explotação de Sargassum no litoral brasileiro, bem como de outros organismos como mexilhões.
