“…The region of Cabo Frio on the coast of the State of Rio de Janeiro is an upwelling area, and can act as a filter for thermophilic species. However, the influence of the cold watermass in the coastal region of Cabo Frio is variable, principally as a function of wind direction (IKEDA et al 1974, IKEDA 1976, MATSUURA 1986.…”

Investigations of the distribution of marine organisms provide a better understanding of the patterns of distribution and dispersal of these animals. Extensions of the distributional limits of decapod crustaceans in Brazilian waters have been recorded steadily and gradually, but these limits still remain poorly understood. The present study provides information extending the known range of eight species of brachyuran crabs and one species of porcellanid crab. The animals were obtained by Scuba diving during a sampling program carried out near Vitória Island, Ilhabela, on the northeastern coast of the State of São Paulo (23º44'04"S-45º01'35"W) between February, 2004 and January, 2005. These new records extend the geographical distributions of the porcellanid Petrolisthes amoenus (Guérin Menéville, 1855), the majoids Mithrax caribbaeus Rathbun, 1920, Mithrax verrucosus H. Milne Edwards, 1832, Nemausa acuticornis (Stimpson, 1871) and Teleophrys ornatus Rathbun, 1901, and the xanthoids Domecia acanthophora acanthophora (Desbonne & Schramm, 1867), Garthiope spinipes (A. Milne Edwards, 1880), Xanthodius denticulatus (White, 1847) and Xanthodius parvulus (Fabricius, 1793) to the São Paulo coast. These new records may be related to different mechanisms of larval dispersal, larval transport by ballast water, or may simply be exceptional records.

“…The 2-day period was chosen because it gives enough time for the upwelling phenomenon to become well established in the region. Ikeda et al (1974) showed that the time lapse between the onset of the NE winds, with magnitude greater than 5 m s -1 , and the first appearance of colder upwelling water is about 24 hours. Then the SST field is used by the TVM-NH model to determine the surface heat flux over the ocean.…”

The co-influence of the sea breeze and the coastal upwelling at Cabo Frio: a numerical investigation using coupled models

A B S T R A C TA coupled atmospheric-oceanic model was used to investigate whether there is a positive feedback between the coastal upwelling and the sea breeze at Cabo Frio -RJ (Brazil). Two experiments were performed to ascertain the influence of the sea breeze on the coastal upwelling: the first one used the coupled model forced with synoptic NE winds of 8 m s -1 and the sign of the sea breeze circulation was set by the atmospheric model; the second experiment used only the oceanic model with constant 8 m s -1 NE winds. Then, to study the influence of the coastal upwelling on the sea breeze, two more experiments were performed: one using a coastal upwelling representative SST initial field and the other one using a constant and homogeneous SST field of 26°C. Finally, two more experiments were conducted to verify the influence of the topography and the spatial distribution of the sea surface temperature on the previous results. The results showed that the sea breeze can intensify the coastal upwelling, but the coastal upwelling does not intensify the sea breeze circulation, suggesting that there is no positive feedback between these two phenomena at Cabo Frio. R E S U M OUm modelo acoplado atmosférico-oceânico foi usado para investigar se há retroalimentação positiva entre a ressurgência costeira e a brisa marítima em Cabo Frio -RJ (Brasil). Dois experimentos foram realizados para verificar a influência da brisa marítima na ressurgência costeira: o primeiro usou o modelo acoplado, forçado com vento de escala sinótica de NE e 8 m s -1 , e o sinal da brisa foi dado pelo modelo atmosférico; o segundo utilizou apenas o modelo oceânico com vento constante de NE e 8 m s -1 . A fim de estudar a influência da ressurgência costeira na brisa marítima, mais dois experimentos foram realizados com o modelo acoplado: um com um campo inicial de temperatura da superfície do mar (TSM), representativo da ocorrência de ressurgência costeira; e o outro com um campo constante e homogêneo de TSM de 26°C. Por fim, mais dois experimentos foram feitos para verificar a influência da topografia e da distribuição espacial da temperatura da superfície do mar nos resultados anteriores. Os resultados mostraram que a brisa pode intensificar a ressurgência, mas a ressurgência não intensifica a brisa, sugerindo não haver em Cabo Frio, retroalimentação positiva entre esses dois fenômenos.

Mithracinae (Decapoda: Brachyura) from the Brazilian coast: review of the geographical distribution and comments on the biogeography of the group

et al. 2012

The geographical distribution of marine organisms, as a result of complex natural processes through geological time, has been changed, sometimes drastically, by species introductions. Instances of species introduction have been recorded worldwide, and the Brazilian coast is no exception. The present review provides an update of the geographical distribution of members of the brachyuran subfamily Mithracinae along the Brazilian coast. Of the 30 species of this subfamily recorded from Brazilian waters, the known geographical limits of more than 17 have been extended in recent decades. The records compiled here demonstrate the great importance of the Amazon River outflow on the geographical distribution of members of Mithracinae, acting as a biogeographical barrier for some species.
