37. Zooplankton of an urban coastal lagoon: composition and association with environmental factors and summer fish kill
Zooplankton may be regarded as a sensitive tool for monitoring environmental variations in coastal lagoons due to their ability to immediately react to changes in the water column trophic features and salinity levels. As a coastal lagoon with a broad history of anthropic influence, Rodrigo de Freitas Lagoon (Rio de Janeiro, Brazil) is widely used for water s

38. Influência dos modelos digitais de terreno na modelagem de circulação hidrodinâmica 2DH: um estudo de caso
Os modelos digitais de terreno (MDT) consistem na representação matemática computacional da distribuição de um fenômeno espacial que ocorre dentro de uma região da superfície terrestre. A qualidade da representação do MDT está influenciada, dentre outros fatores, pela origem do dado e pelo algoritmo interpolador utilizado. A caracterização da ci

39. Poluentes orgânicos persistentes na biota marinha do Arquipélago de São Pedro e São Paulo / Persistents Organic Pollutants in marine biota of the São Pedro e São Paulo Archipelago
Some oceanic islands, such as São Pedro e São Paulo Archipelago may be considered remote areas and preserved due to its distance from the mainland. However, these areas are not exempt from the influence of anthropogenic agents from coastal regions, such as persistent organic pollutants (POPs). This proposal aimed to determine the occurrence and distributio

40. Levantamento dos níveis de radioatividade natural em águas do alto Vale do Ribeira à planície costeira do litoral sul do Estado de São Paulo / Assessment of natural radioctivity levels in waters from Higher Ribeira Valley until the southern Sao Paulo State coastal plain
The complex exchange of fluvial, subsurface and seawater within a coastal area directly affects global biogeochemical cycles and the application of isotopic tracers, mainly natural radionuclides from U and Th series, is a powerful tool to track sources and sinks of trace elements and nutrients to this systems. The unique Ra signature applied to quantify the

41. Consequências da barragem eclusa do Canal São Gonçalo para a ictiofauna do sistema Patos-Mirim / Consequences of the São Gonçalo channel s dam-lock to the ichthyofauna of the Patos-Mirim system
The present study aimed to investigate the consequences of the São Gonçalo channel dam-lock in the structure of the marine, estuarine and freshwater fish assemblies that inhabit the Patos-Mirim lagoon system. The study area was the São Gonçalo channel that connects the Patos Lagoon with the Mirim Lagoon. Sampling took place monthly during years 2005 (12

42. Tourism and Socio-environmental transformations in the Coastal Iguape-Aquiraz-CE / O turismo e as transformaÃÃes socioambientais no litoral do Iguape-Aquiraz-CE
The subject of this work was the coastal district of Iguape located in the city of Aquiraz, east coast of CearÃ, 38 km from Fortaleza. In recent years, there has been a change in tourism demand in that region and increased investment by both the public and private capital and international levels. Tourism is an economic activity that transforms space and re

43. A produção do espaço: ausência de integração das políticas públicas na zona costeira do Município de Fortaleza-CE
The worldwide preoccupation with the activities developed in costal zones and their consequences takes many countries to develop studies in order to find solutions with partnerships. Within this band of ocean near the coast, actions and policies are applied without a cooperative guideline in the sense of depredating no natural existing resources and do not p

44. Padrões diagenéticos em arenitos de sistemas de Sabk ha costeiros-eólicos: um estudo comparativo dos reservatórios Juruá da área de Urucu, Bacia de Solimões, AM
Coastal-eolian sabkha sandstones from different ages and basins show similar diagenetic patterns, which understanding is important for their evaluation as geochemical systems and as hydrocarbon reservoirs. The Carboniferous sandstones of the Juruá Formation (Solimões Basin) are one of the most important gas reservoirs of Brazil. The sandstones and interbed

45. Desenvolvimento de um sistema computacional para geração automática de mapas de vulnerabilidade como ferramenta de auxílio às ações de prevenção ao derramamento de óleo em áreas costeiras
The northern portion of the Rio Grande do Norte State is characterized by intense coastal dynamics affecting areas with ecosystems of moderate to high environmental sensitivity. In this region are installed the main socioeconomic activities of RN State: salt industry, shrimp farm, fruit industry and oil industry. The oil industry suffers the effects of coast

46. Análise do Método do Programa QualityCoast: estudo de caso no Município de Balneário Camboriú, SC
Balneario Camboriu is primarily engaged in the tourist resort of sun and sand, and this is often seasonal and massive, contributing, in many cases, the loss of environmental quality and the weakening of destinations for significant income generation and employment. The city still suffers a violent process of urbanization and vertical housing, traffic congest

47. Variabilidade interanual (10 anos) da comunidade zooplanctônica na região costeira do Espírito Santo, em área sob influência de efluente industrial aquecido
In the last decade (1998-2007) collections were made of biotic (zooplankton) and abiotic (temperature and salinity) in the coastal waters adjacent to Praia Mole, in the Espírito Santo, in order to monitor the potential effects of disposal a heated effluent on the zooplankton community. This study aimed to analyze the data generated by this monitoring by obs
