Análise geoambiental da plataforma continental Rasa Equatorial, por meio de sensoriamento remoto e dados sedimentológicos: parrachos de Rio do Fogo-RN, Brasil

In the shallow continental shelf in Northeastern Rio Grande do Norte - Brazil, important underwater geomorphological features can be found 6km from the coastline. They are coral reefs, locally known as “parrachos”. The present study aims to characterize and analyze the geomorphological feature as well as the ones of the benthic surface, and the distribution of biogenic sediments found in parrachos at Rio do Fogo and associated shallow platforms, by using remote sensing products and in situ data collections. This was made possible due to sedimentological, bathymetric and geomorphological maps elaborated from composite bands of images from the satellite sensors ETM+/Landsat-7, OLI/Landsat-8, MS/GeoEye and PAN/WordView-1, and analysis of bottom sediments samples. These maps were analyzed, integrally interpreted and validated in fieldwork, thus permitting the generation of a new geomorphological zoning of the shallow shelf in study and a geoenvironmental map of the Parrachos in Rio do Fogo. The images used were subject to Digital Image Processing techniques. All obtained data and information were stored in a Geographic Information System (GIS) and can become available to the scientific community. This shallow platform has a carbonate bottom composed mostly by algae. Collected and analyzed sediment samples can be classified as biogenic carbonatic sands, as they are composed 75% by calcareous algae, according to the found samples. The most abundant classes are green algae, red algae, nonbiogenic sediments (mineral grains), ancient algae and molluscs. At the parrachos the following was mapped: Barreta Channel, intertidal reefs, submerged reefs, the spur and grooves, the pools, the sandy bank, the bank of algae, sea grass, submerged roads and Rio do Fogo Channel. This work presents new information about geomorphology and evolution in the study area, and will be guiding future decision making in the handling and environmental management of the region

Variação no conteúdo protéico e pigmentar em variantes cromáticas de Gracilaria domingensis nas populações naturais de Rio do Fogo-RN, BRASIL

The seaweed Gracilaria domingensis is a common species in the coast of Rio Grande do Norte. This species lives in the intertidal zone, where colour strains (red, green and brown) co-occur during the whole year. Seaweeds that live in this region are exposed to daily changes and to the rhythm of the tide. During the low tide they are exposed to dissection, hiper-or hipo-osmotic shock, high temperatures and high irradiance. The aim of this study was to analyze whether the pigment and protein content of the colour strains of G. domingensis is affected by some environmental parameters in a temporal scale. The seaweeds were collected during 10 months in the seashore of Rio do Fogo (RN). The total soluble proteins and the phycobiliprotein were extracted in phosphate buffer and the carotenoids were analyzed by a standardized method through HPLC-UV. The pigments analysis showed that phycoerithrin is the most abundant pigment in the three strains. This pigment was strongly correlated with nitrogen and the photosynthetically active radiation. Chlorophyll presented higher concentrations than carotenoids during the whole, but the ratio carotenoid/chlorophyll-a was modified by incident radiation. The most abundant carotenoid was ß-carotene and zeaxanthin, which had higher concentrations in the higher radiation months. The concentration increase of zeaxanthin in this period indicated a photoprotective response of the seaweed. The three strains presented a pigment profile that indicates different radiation tolerance profile. Our results pointed that the green strain is better adapted to high irradiance levels than the red and brown strains

O Emprego Conjunto das Operações de Informação no Brasil como forma de fogo não cinético nas Operações Conjuntas.

O atual ambiente operacional, tem sentido profundas mudanças, fruto especialmente, da evolução tecnológica global, fazendo com que a tomada de decisão dependa ainda mais dos sistemas de informação. Para fazer face a esta realidade têm sido atualizadas e desenvolvidas conceções doutrinárias, onde se incluem as Operações de Informação, com o intuito de dar resposta aos desafios vindouros. Sendo o objeto de estudo deste trabalho as Operações de Informação, analisamos essa temática à luz da doutrina da Organização do Tratado do Atlântico Norte (OTAN) e do Exército Brasileiro, com vista a determinar contributos que possibilitem a sua conceção de emprego no Brasil a nível conjunto. Após tratada, sistematizada e analisada a informação recolhida, constatamos que a OTAN utiliza instrumentos de poder de maneira abrangente e tem conduzido as Operações de Informação para maximizar os efeitos produzidos no ambiente da informação, como uma função integradora de capacidades. O Exército Brasileiro possui doutrina consubstanciada de emprego tático das Operações de Informação. Assim sendo, esta investigação permitiu concluir que o estudo das Operações de Informação, através de contributos do Exército Brasileiro e da OTAN abre caminhos para o estabelecimento inicial de uma conceção doutrinária para o Brasil a nível conjunto. Abstract: The current operating environment, it makes sense profound changes, especially fruit, the global technological evolution, making decision making depends further information systems. To address this reality has been updated and developed doctrinal conceptions, which includes the Information Operations, in order to meet the challenges ahead. As the object of study of this work the Information Operations, we analyzed this issue in the light of the doctrine of the North Atlantic Treaty Organization (NATO) and the Brazilian Army, to determine contributions to enable your use of design in Brazil at the joint level. After treated, systemized and analyzed the information collected, we found that NATO uses power tools in a comprehensive manner and has led the Information Operations to maximize the effects in the information environment as an integrating function capabilities. The Brazilian Army has embodied the doctrine of tactical employment of Information Operations. Therefore, this investigation has concluded that the study of Information Operations through contributions of the Brazilian Army and NATO open paths for the initial establishment of a doctrinal design for Brazil at the joint level.
