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. The sedimentary record of wet and dry eolian systems in the Cretaceous of Southeast Brazil: stratigraphic and paleogeographic significance
Abstract Sedimentologic and stratigraphic studies of paleo-deserts from the Brazilian Cretaceous are of great potential to understand the paleoclimate and paleogeography of Gondwana during its final rifting stage. Herein, we describe and discuss two depositional units characterized by two distinct eolian systems that are bounded by a long-lived unconformity.

3. Interannual Variability of Precipitation for the Centro de Lançamento de Alcântara in ENSO-Neutral Years
ABSTRACT: The interannual variability of precipitation in El Niño/Southern Oscillation-neutral years was studied for the Centro de Lançamento de Alcântara region. Monthly precipitation, sea surface temperature, wind at 925 hPa and outgoing longwave radiation data from various gridded datasets for the 1951-2010 period (60 years) were used. The data groupin

4. Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo
The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And

5. Características da precipitação pluviométrica do nordeste brasileiro e seus padrões de acoplamento com as TSM do Pacífico Equatorial e Atlântico Sul. / Rainfall characteristics in northeastern brazil and their patterns coupling with sst equatorial Pacific and South Atlantic.
The eastern coast of the Northeast Brazil (NEB) is a region where transient weather systems interact with local systems, modulating their frequency and intensity. Understanding the mechanisms of such interactions may be instrumental in explaining the observed precipitation patterns in this region. The objective of this work is quite within this scope and tak

6. Upper tropospheric cyclonic vortex and Brazilian Northeast jet stream in El Niño and La Niña years. / Vórtice ciclônico em altos níveis e corrente de jato do nordeste brasileiro em anos de El Niño e La Niña.
A ligação entre Vórtice Ciclônico em Altos Níveis (VCAN) e a Corrente de Jato do Nordeste Brasileiro (CJNEB), foi analisada durante 9 anos entre 1988-2000, divididos em períodos de El Niño, La Niña e Neutro. Através dos produtos de reanálise do NCEP, e imagens do satélite METEOSAT no canal infravermelho, foram observados 167 VCANs, em grande maior

7. Caracterização física e dinâmica de episódios de chuvas intensas nas regiões sul e sudeste do Brasil / Physical and dynamical characteristics of heavy rainfall episodes in southern and southeastern Brazil
The heavy rainfall events occurred in Southern and Southeastern Brazil between 1960 and 2004 are investigated. It is observed positive trends in the annual frequency of these events in both regions in this period of 45 years. The trend in Southern Brazil is more significant. The atmospheric environments associated with these events also are investigated, but

8. Levantamento de formicídeos de fragmento de floresta atlântica no município de Eng. Paulo de Frontin, RJ (Hymenoptera, Formicidae). / Formicidae survey in a fragment of Floresta Atlântica in the county of Eng. Paulo de Frontin, RJ (Hymenoptera, Formicidae).
The east coast of Brazil, is lined with a chain of mountains where a forest known as Mata Atlântica develops. The vegetation of these mountains, because of its proximity with the coast, is under the influence of the trade winds full of humidity, from the ocean. Originally the forest extended for almost all the coast, from Rio Grande do Norte to the Rio Gran

9. TÃcnicas de Sensoriamento Remoto para Monitoramento Ambiental com AplicaÃÃes em Recursos Pesqueiros no AtlÃntico Tropical / Techniques of Remote Sensing for Environmental Monitoring with Applications in the Atlantic Tropical Fishing Resources
In this work we studied, from data obtained from sensors on board satellites, monthly and seasonal patterns of physical and biological parameters on the Tropical Atlantic, the area between the latitudes 30 Â N - 30 Â S and longitudes 80 Â W - 5 Â E. The physical environment (temperature of the sea surface, measured by the sensor VHRR and wind, measured b

10. Dinâmica de populações de cianobactérias em reservatório eutrofizado no semi-árido nordestino brasileiro.
The Armando Ribeiro Gonçalves reservoir, located in the semi-arid of the Rio Grande do Norte (06o08 S ; 37o 07 W), in Northeast Brazil, represents 68% of the total surface water accumulated in the state. The reservoir, with maximum volumetric capacity of 2.4 x 109, provides 400 thousands habitants and also is destined to irrigation, leisure and fishing. It

11. Uma análise do campo de vento de superfície sobre o Oceano Atlântico Tropical e Sul usando dados do escaterômetro do ERS / An analysis of the surface wind field over tropical and South Atlantic Ocean using ERS scatterome.er data
Monthly mean and standard deviation values of surface winds of the Atlantic Ocean sector from 20o N to 40o S were generated from the ERS 1/2 scatterometer data. The data was obtained from IFREMER and covers the period from December 1991 to November 1998. The objective of this effort was the analysis of the spatial and temporal variability of the wind field f
