O conjunto de dados usado no estudo atual consiste na matriz Pacific Current Meter 3 (PCM3), que foi uma parte significativa da contribuição australiana para o World Ocean Circulation Experiment para estudar a variabilidade ...

Através do Programa Antártico Brasileiro (PROANTAR), muitos estudos tem se dedicado a vários aspectos da oceanografia antártica e aos processos de tele conexão entre o oceano Austral e o oceano Atlântico Sul. Valendo-se ...

Regional formation of deep and bottom water masses around the Antarctic continentalshelf is one of the most important processes contributing to variability of the globalmeridional overturning circulation deep cell. Southern ...

The aim of present study was to evaluate the Hg concentration in two species of fish (Astyanax sp and Corydoras paleatus) and its potential use as a biomonitor, in order to know if the use of pesticides and fertilizers ...

We describe the seasonal and interannual variability of volume transports in the Weddell and Ross Seas using the 1/12◦ 20-yr simulation of the OCCAM global ocean general circulation model. The average simulated ...

Core sediments that were sampled from the coastal zone of the Santa Rosalía mining region and the adjacent deeper area of the Gulf of California were analysed by an instrumental neutron activation analysis (INAA). The ...

We analyzed the ability of the Estimating the Circulation and Climate of the Ocean – Phase II (ECCO2) reanalysis to represent the hydrographic properties and variability of Antarctic Bottom Water (AABW) in the ...

In waters surrounding James Ross Island (JRI), which is generally inaccessible, high chlorophyll-a concentration [Chla] can often be detected during summer periods by ocean color imagery. The region is influenced by a ...

Oceanic eddies exist throughout the world oceans, but are more energetic when associated with western boundary currents (WBC) systems. In these regions, eddies play an important role in mixing and energy exchange. ...

Twenty-five natural and synthetic cationic polymers of differentmolecular weightsand charge densitieswere evaluated for microalgae flocculation. Tanfloc is a naturallow molecular weight tanninpolymer whereas Zetag and ...

Este trabalho tem como objetivo estudar a variabilidade da energia cinética turbulenta (EKE) oceânica na região da Confl uência Brasil-Malvinas (CBM). Dados altimétricos de anomalia de velocidade geostrófi ca foram ...

A NCAR-CCSM3 (National Center for Atmospheric Research – Community Climate System Model version 3) state-of-the-art transient paleoclimate simulation with prescribed freshwater inflows is used to investigate the changes ...

The usage of so-called turbulence closure models within hydrodynamic circulation models comes from the need to adequately describe vertical mixing processes. Even among the classical turbulence models; that is, those based ...

Monthly sampling campaigns were carried out between February 2010 and January 2011 to evaluate the spatial and temporal distribution of nutrients (ammonium, nitrite, nitrate, dissolved organic nitrogen, phosphate, dissolved ...

This research analyzed the microencapsulated diet degradation in pacu (Piaractus mesopotamicus) larvae intestine. The pacu larvae received the following feeding treatments: AMD- larvae fed initially Artemia nauplii for ...

n this study it was hypothesised that increasing water retention time promotes phytoplankton bloomsin the shallow microtidal Patos Lagoon estuary (PLE). This hypothesis was tested using salinity variationas a proxy of water ...

Um dos maiores problemas enfrentados na aquicultura é a deterioração da qualidade da água das criações e dos ambientes receptores. Para minimizar esse problema em criações de peixes e camarões com limitada renovação de ...

O lixo do município do Rio Grande vem sendo depositado nas margens da enseada do Saco do Martins (estuário da Lagoa dos Patos) há aproximadamente três décadas. Esta região é classificada pela Fundação Estadual de Proteção ...

Climate change can be associated with variations in the frequency and intensity of extreme temperatures and precipitation events on the local and regional scales. Along coastal areas, flooding associated with increased ...
