1. Estudo de agitação, correntes induzidas por ondas e balanço sedimentar da região do Porto de Tubarão e Praia de Camburi, Vitória/ES / Study of wave clima, wave induced currents and sedimentary balance in the region of the region of the Tubarão harbour, Vitória-ES
Os ambientes costeiros podem ser caracterizados por sua grade dinâmica, onde existe o embate entre o continente e o mar. A dinâmica sedimentar da linha de costa constitui conhecimento básico em obras de engenharia e na compreensão do ambiente costeiro. Buscou-se compreender os mecanismos do funcionamento dinâmico da região em torno do Porto de Tubarão

2. Determinação da recarga profunda na bacia-piloto do Ribeirão da Onça em zona de afloramento do Sistema Aqüífero Guarani a partir de balanço hídrico em zona saturada / Determination of the deep recharge in the Ribeirão da Onça pilot basin in the outcrop zone of the Guarani Aquifer System through water balance in the saturated zone
Main objective of this work was the determination of the deep recharge in the Ribeirão da Onça basin through water balance in the soil saturated zone. This basin is located in the outcrop zone of the Guarani Aquifer System (GAS) in the São Paulo State - Brazil and is covered by cenozoic sedimentary soil. The water balance model involved the determination

3. Morfologia e sedimentologia das praias do litoral sul do municÃpio de Olinda - PE
The littoral of Olinda has spaces with coastal erosion since the last century. Trying to soften the erosion and stabilize the shoreline, a good range of engineering techniques were used in the last 88 years. During the 60s decade were made two breakwaters semi submerged in front of the Carmo beach and 38 groins along the 1,8 km of the Bairro Novo beach. The

4. ImplicaÃÃes de fatores ambientais na deposiÃÃo de plÃsticos no ambiente praial de um ecossistema estuarino
Marine debris are materials from anthropogenic sources, such as plastics, paper, glass, wood and others, that enter the marine and coastal environments from multiple sources, and are considered as one of the most important marine pollutants by the turn of the XXI Century. Sandy beaches are usually more studied because they are relatively easy to be monitored

5. Biodisponibilidade de mercurio e outros metais-traço em sedimentos do Rio Cubatão, Sistema Estuarino de Santos-Cubatão (SP) / Bioavailability of mercury and other trace-metals in sediments of Cubatão River, Santos-Cubatão Estuarine System (SP)
Coastal-estuarine ecosystems from the south of São Paulo State are presently degraded specially in Cubatão municipality, in consequence of population concentration and, industrial and petrochemical complexes. These environmental impacts have begun in the 1950s after the construction of the largest Latin America petrochemical complex in the Cubatão city.

6. Mercury occorrence at the Iguaçu River Basin, State of Parana, Brasil / Ocorrencia de mercurio na Bacia do Rio Iguaçu, Estado do Parana, Brasil
Mercury contents in rocks, soil and stream sediment were determined to investigate the origin of the geochemical anomaly found in sediments of the Iguaçu River, as indicated in previous studies of a regional geochemistry survey. Except for its headwaters in the Curitiba area, with Precambrian basement rocks and Pleistocenic sediments of the Curitiba Basin,

7. RelaÃÃes entre a dinÃmica costeira e a meiofauna dos sedimentos praiais do litoral da Ilha de Itamaracà - PE / Relations between the coastal dynamics and meiofauna of the praiais sediments of the coast of the Island of Itamaracà - PE
The studied area is comprised of The Forte Orange, SÃo Paulo, Forno da Cal, Pilar, Jaguaribe and Sossego in Itamaracà Island. The study aimed to know the relationship between shore dynamic agents and the sediment interstitial fauna. Monthly collections of interstitial fauna were carried out between November 2003 and October 2004. The samples of the interst

8. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w

9. Examination of hypotheses for the Permo–Triassic boundary extinction by carbon cycle modeling
The biological extinction that occurred at the Permian–Triassic boundary represents the most extensive loss of species of any known event of the past 550 million years. There have been a wide variety of explanations offered for this extinction. In the present paper, a number of the more popular recent hypotheses are evaluated in terms of predictions that t
