13. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in

14. Estudo da circulação hidrodinâmica e da dispersão de óleo na zona costeira entre Macau e Galinhos RN
This paper presents a study on coastal hydrodynamics and the spread of an oil spill in waters off Macau and Galinhos, on the east coast of the state of Rio Grande do Norte in Northeast Brazil. This area has a very marked coastal dynamic owing to the complexity of its geomorphological features, developed in a regime of semidiurnal mesotides involving reefs, s

15. Proteção jurídica das áreas úmidas e os direitos socioambientais / Wetlands protection and the socioenvironemental rights
Wetlands are transitional ecosystems, located between the land and the aquatic environments, sharing characteristics of both areas. Can be found in bays, estuaries, deltas, coral reefs, salt marshes, mangroves, coastal plains, bogs, dunes, swamps, riparian forests, leas, rice fields, etc. The modern capitalist societies have been over exploring these wet eco

16. Ecologia reprodutiva do peixe-donzela, Stegastes fuscus cuvier, 1830 (osteichthyes: pomacentridae) em arrecifes rochosos da praia de Búzios, Rio Grande do Norte, Brasil
A ecologia reprodutiva dos peixes é fundamental na racionalização dos métodos de exploração e na proteção dos estoques naturais. O presente estudo analisou aspectos relacionados à reprodução do peixe-donzela, Stegastes fuscus, durante o período de outubro de 2004 a setembro de 2005, nos arrecifes rochosos da praia de Búzios, Nísia Floresta, RN.

17. Caracterização e classificação de solos da Ilha de Fernando de Noronha (PE)
In the main island of Fernando de Noronha Archipelago, the dry tropical climate with oceanic influence and the recent parent material of volcanic origin, are responsible for the small weathering of soils with high scientific importance for the development of the Brazilian System of Soil Classification (SiBCS). Seven representative soil profiles, involving tw

18. Application of image of the satelite Landsat TMS and of vertical aÃrias photographs for the mapping of coastal reefs and analysis of the littoral physical processes related - TAMANDARÃ, PE, BRAZIL / AplicaÃÃo de imagem do satelite Landsat TMS e de fotografias aÃrias verticais para o mapeamento dos recifes costeiros e anÃlise dos processos fÃsicos litorÃneos relacionados - TAMANDARÃ, PE, BRASIL
The coastal area is one of the most complex and sensitive environments of nature, presenting great ecosystem diversity, coral reefs among them, and is widely recognized to be approaching a critical situation. The modern expressive urban occupation of coastal areas all over the world causes great pressure and marked alterations to these environments. The pres

19. SANDY BEACH MORPHODYNAMICS AND MACROBENTHIC COMMUNITIES IN TEMPERATE, SUBTROPICAL AND TROPICAL REGIONS - A MACROECOLOGICAL APPROACH
A comprehensive study involving 52 microtidal beaches spanning from reflective to dissipative states and located in tropical, subtropical and temperate regions in the Atlantic, Pacific and Indian oceans was carried out to unravel the relative roles of latitude and beach morphodynamics in determining beach macrobenthic species richness, abundance, biomass and

20. Use of space and temporal distribution of Trichechus manatus manatus Linnaeus in the region of Sagi, Rio Grande do Norte State, Brazil (Sirenia, Trichechidae)
The marine manatee Trichechus manatus manatus Linnaeus, 1758 is endangered in the Brazilian Atlantic coast due to indiscriminate hunting practiced in the past, and to the low reproductive rate of the species. This work studies its use of space and temporal occurrence in the coastal area of Sagi, Northeastern Brazil. Daily observations from the beach of the a

21. Potencial atrator de tubarões costeiros em recife artificial no litoral norte do estado do Rio de Janeiro, Brasil
Artificial reefs have been used in many countries to increase coastal fishery productivity. In order to increase fish attraction to the Northern Coast of Rio de Janeiro State, it was installed an artificial reef (1,500 m²) 5 nautical miles off Manguinhos's Bay (São Francisco de ltabapoana, Rio de Janeiro). The artificial structures were made of tires, conc

22. Patterns of sediment dispersion coastwise the State of Bahia - Brazil
Using the average directions of the main wave-fronts which approach the coast of Bahia State - coinciding with that of the main wind occurring in the area - and of their periods, we define a wave climate model based on the construction of refraction diagrams. The resulting model of sediment transport was able to reproduce, in a general way, the sediment disp

23. Sedimentos superficiais da plataforma continental interna do estado da ParaÃba
The internal continental shelf in the state of ParaÃba was divided into three sectors: central and northern, considering the coastal line morphology, bathymetric features and sedimentary information. The southern sector comprises the region extending the latitude 7Â35â00âS to Branco Cape. The coastal line is basically staight, trending N-S, characterized
