1. The north Brazil undercurrent and the wind driven hydrodynamics in Japaratuba submarine canyon, Brazil
Abstract The circulation induced by the wind and the North Brazil Undercurrent (NBU) in and surrounding the Japaratuba submarine canyon on the continental shelf of the basin of Sergipe and Alagoas is described using numerical modeling. The numerical simulations were implemented to determine the canyon influence in the local hydrodynamics and in the volume fl

2. Modelagem de plumas de efluentes entre Praia Grande e Peruíbe, litoral do estado de São Paulo, Brasil
RESUMO O presente trabalho teve como objetivo monitorar a dispersão de plumas de efluentes provenientes dos emissários submarinos de Praia Grande e do Rio Itanhaém, por meio do processamento do modelo Delft3D (módulos hidrodinâmico e de qualidade da água) e do modelo Visual Plumes (módulo UM3). A modelagem de campo próximo indicou que as correntes ge

3. Advances of Submarine Groundwater Discharge Studies in South America
Submarine groundwater discharge (SGD) is the hidden portion of water that discharges into the ocean across the ocean-land interface, and it is considered one of the hydrological cycle's major components. Two decades ago, SGD in South America was undocumented, and significant advances on this field has occurred since then. This paper presents the results of S

4. Brazil’s Nuclear Submarine: A Broader Approach to the Safeguards Issue
Abstract The article discusses the issue of nuclear-propelled submarines as a nuclear non-proliferation question, addresses the issue of safeguards procedures and arrangements, and suggests a broader, political approach to allay international concerns. Such safeguards arrangement would set the precedent for future arrangements, and particularly if integrated

5. A Nuclear Submarine in the South Atlantic: The Framing of Threats and Deterrence
Abstract In this article, we analyse one aspect of Brazilian nuclear policy during the tenure of the Workers Party (2003–2016): the development of a nuclear-propelled submarine. We propose that the project of building a nuclear-propelled submarine has become possible partly because of the mobilisation of a set of arguments for the construction of the South

6. Soft Power, Hard Aspirations: the Shifting Role of Power in Brazilian Foreign Policy
Journalists and policy analysts have highlighted the emergence of Brazil as a regional power. However, little attention has been paid to its foreign policy strategies. Brazil's rise to prominence in world politics represents the historical culmination of a foreign policy featuring two main strategies – persuasion and consensus building – both of which em

7. Submarine groundwater discharge revealed by radium isotopes (Ra-223 and Ra-224) near a paleochannel on the Southern Brazilian continental shelf
A descarga de água subterrânea ("Submarine Groundwater Discharge"; SGD) é um importante elo entre continente-oceano. No Brasil, embora haja um crescente interesse em estudos sobre este tema, eles ainda são raros e se restringem às zonas costeiras. A presente investigação explora as evidências SGD na Plataforma Continental do Sul do Brasil, as quais i

8. Simple model for CO2 absorption in a bubbling water column
A simple analytical model is presented for the time-evolution of dissolved CO2 concentration in a batch water column. The application in mind is the removal of the CO2 produced by the propulsion plant of a submarine cruising underwater. The model is based on a constant number of constant size CO2 bubbles within the water column, with uniform gas injection th

9. Lipídios como indicadores de processos biogeoquímicos em sedimentos da margem continental do Estado do Rio de Janeiro / Lipids as biogeochemical process indicators in sediments of the continental margin of Rio de Janeiro State
Este estudo constitui parte do Projeto Habitats Heterogeneidade Ambiental da Bacia de Campos coordenado pelo CENPES/Petrobras, um projeto multidisciplinar de caracterização ambiental que considera as diferentes feições e habitats da margem continental do sudeste brasileiro. O objetivo desta tese foi investigar os processos relacionados com a origem, o tr

10. Estudo hidrogeoquímico, sedimentológicos e dos foraminíferos de áreas submetidas a esgotos domésticos e petroquímicos do canal de São Sebastião, SP / não informado
O presente estudo teve por objetivo analisar a influência da disposição oceânica de esgotos domésticos e petroquímicos na coluna d\ água, nos sedimentos e nas associações de foraminíferos bentônicos. Para atingir tal objetivo foram coletadas amostras próximo aos emissários do Araçá, do Saco da Capela e do Terminal Petrolífero Almirante Barros

11. Estudo de viabilidade do sistema de ancoragem de uma unidade flutuante de produção e armazenamento \"FPSO\" acoplada a um sistema de completação seca \"TLWP\". / Mooring system feasibility study of a floating production and storage unit \"FPSO\" coupled to a dry tree system \"TLWP\".
The oil and gas production in Brazilian fields are commonly found in deep water and situated far away from the coast, reaching distances of more than 100 km as, for example, in the Campos Basin or Santos Basin. Due to the heavy oil and lack of pipeline infrastructure found in these fields, not only subsea equipments that must support high pressure but also l

12. Morfodinâmica associada entre duna, praia e zona submarina como subsídio a adequada ocupação do espaço costeiro na Praia do Peró - RJ. / Morphodynamics associated between dune, beach and underwater area as an aid to proper occupation of coastal space in Praia do Pero - RJ.
The coastline offers a veritable mosaic of diversity in coastal landforms, which enable the development of a number of different economic activities. Coastal environments are highly dynamic and involve a complex series of continental and oceanic processes. The beach of Pero, located between Cape Buzios and Cabo Frio, Rio coast, appears as an area distinct fr
