Autores: SOUZA, O. C. de; ARAÚJO, M. R.; USSAMI, N.; FISSEHA, S.; KONZEN, L.
Nas últimas décadas, grandes áreas de Cerrados de Mato Grosso do Sul foram convertidas em sistemas produtivos agrícolas e pastoris, sem a devida observância do potencial de utilização das terras. Com o tempo, algumas regiões, como a Bacia do Rio Taquari, passaram a apresentar problemas ambientais de grandes proporções em resposta a processos erosivos, cuja evolução progressiva sugere ineficiência dos sistemas de manejo visando à conservação ambiental. Os processos erosivos, estabelecidos na região de planaltos da alta Bacia do Rio Taquari, manifestam-se em escalas temporal e espacial ainda não inteiramente compreendidas e consideradas. Há falta de estudos sobre a erosão fluvial, principalmente em cabeceiras de drenagem, que acumulam grandes quantidades de...

Instabilites sous-marine etudiees par submersibles
Provedor de dados: 5
Autores: Savoye, Bruno.
Sediment instability appears to be important as a part of global sedimentary budget. Among the various types of sedimentary instabilities, submarine slides are probably the most spectacular and the hardest to study and predict, although their consequences on human and industrial marine activities can be dramatic. IFREMER is conducting a research project on this topic. An area off Nice (France) has been particularly studied because of its recent activity. Mapping and instability area detection have been carried out. With the possibility of direct interactive observation and highly accurate submarine in -situ operation, the submersible is an extremely efficient tool for sediment studies, but diving purposes have to be precisely defined to provide useful...

Subjected to multiple modifications which are responsible for important disruption in the functionning of the lagoon ecosystem during the last decenies, this lagoon is one of the most important sites for the region economy. The aim of this study is to propose a knowledges synthesis utilizable for a future fitting and management water plan. In fact, many studies realized during the last years are obsolete or uncompleted to explain the present state. Hydrogeololical studies, the most important, are not completed to understand the karst-lagoon relations. The wind-driven flow in the closed bassin, must be considered to explain biogeochemical process and the sewage discharges dispersal in the lagoon. Numerical models, with new physicochemical data, appear to be...

Observatoires sismiques sur le fond de la mer
Provedor de dados: 5
Autores: Avedik, Felix.
Detecting and localizing nuclear blasts was an essential stimulus of the actions undertaken in the 1960's to emplace seismological observatories on the seafloor. The plate-tectonic theory, in which the oceanic areas play a major role, greatly accelerated the evolution of modern oceanology. The contribution of Ifremer's department of Marine Geosciences, in helping to advance this area of research, has been significant since 1972. The need for refraction studies to explore the deep structure of the margins and ocean-continent transition zones led us to design a deep-sea Ocean Bottom Seismograph (OBS) MK I in 1975, rated to 6,000 metres depth. This system introduced, for the first time, the concept of "isolated seismic sensors". This principle was adopted...

The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (similar to the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential Southern Hemisphere companion to the Arctic Climate Impact Assessment.

Apex, actively positioned exploration system.
Provedor de dados: 5
Autores: Greger, B.
A conceptually new, modularly designed exploration system for the deep sea (600 m) has been constructed and tested. In its base unit, different soil sampling tools can be integrated. These are, for the time being, a drill core barrel with 0 48 mm iD and a length of 500 mm for rocky basements as a box corer for softer soils as well as an orange peel grab. Towed along via a coaxial cable from a research vessel, the system is TV-guided and can be actively positioned by means of 2 thrusters in order to be lowered precisely and horizontally levelled on the seafloor. The total system is operated by the help of an onboard computer and may be controlled by sensor displays and operation messages. Microprocessors control the underwater unit which is partially...

Observations dans les zones peu accessibles de l'environnement bathyal (biologie et geologie) grace a l'usage des soucoupes plongeantes
Provedor de dados: 5
Autores: Roux, M.
On the bathyal slope for continental margins, steep and rocky substrates punctuated with cliffs and collapsing zones are frequently found. As survey and sampling with the classical technics from the sea surface is practically impossible in such an environment, in situ exploration with a submersible allows significant advances in ecology, with implications in paleoenvironment reconstruction. Mixing of material from shallow-water and deep-sea origins into bathyal sedimentation suggests that the so-called "fossil assemblages of outer platform" were frequently misinterpreted. Dense populations of animals closely related to fossil groups which were only considered as relict of the Past ("living fossils") and previously interpreted as shallow-water inhabitants...

During the Equanaute survey (June 1992), fourteen submersible dives were performed between 4950 and 2250 m water depths across the southern slope of the Cote d'Ivoire-Ghana Marginal Ridge (CIGMR), in the eastern Equatorial Atlantic. The CIGMR, a high-standing topographic marginal ridge along the Cote d'Ivoire-Ghana transform margin, is believed to result from a complex structural evolution due to the specific wrench-related rifting between Western Equatorial Africa and Northeastern Brazil, in Early Cretaceous times. In this paper we report and discuss geological observations made during dives, and sample analyses to resolve the lithology, paleoenvironmental conditions, age and origin of the CIGMR. The data help in better characterizing the different...

MarsiteCruise was undertaken in October/November 2014 in the Sea of Marmara to gain detailed insight into the fate of fluids migrating within the sedimentary column and partially released into the water column. The overall objective of the project was to achieve a more global understanding of cold-seep dynamics in the context of a major active strike-slip fault. Five remotely operated vehicle (ROV) dives were performed at selected areas along the North Anatolian Fault and inherited faults. To efficiently detect, select and sample the gas seeps, we applied an original procedure. It combines sequentially (1) the acquisition of ship-borne multibeam acoustic data from the water column prior to each dive to detect gas emission sites and to design the tracks of...

Misinterpreting by localism: transposing European geology and tectonics onto Antillean islands
Provedor de dados: 16
Autores: Donovan, S.K.
Le Grand (1988, pp. 80-81, 97) defined ‘localism’ “when geologists are most influenced by data found close to them in time and space and within their own disciplinary specialties”. Jamaica has been prone to localist interpretations made by some of its most notable geologists.

Avian biogeography on western Indian Ocean islands: eustatic sea levels, geological events and anthropogenic changes
Provedor de dados: 16
Autores: Hume, J.P.
The south-western Indian Ocean islands, excluding the microcontinent of Madagascar, are geologically complex and diverse. They have been subject to drastic sea level changes, volcanic events and anthropogenic changes, all of which have contributed to confuse understanding of their avian biogeography. An array of factors have affected these avifaunas, based on palaeontological, historical and molecular evidence,which together have shown that avian biogeography is not congruent with the relative age and size of the islands.

Small is beautiful? Progress and collections of the Geology Museum, University of the West Indies, Mona
Provedor de dados: 16
Autores: Donovan, S.K.; Jackson, T.A.; Brown, I.C.; Wood, S.J.
Geology has been taught at the University of the West Indies, Mona, since 1961. The associated Geology Museum (UWIGM) opened to the public in 1969/1970, although the idea for such a museum was over 100 years old at that time. The collections of the UWIGM share many hazards with those in museums in other parts of the world, such as dust, insect pests and indifferent specimen records, and some that are less common, such as earthquakes and hurricanes. The curatorship is not tenured. Since the mid 1980s the UWIGM has become a more dynamic visitor attraction in many ways, shaking off its ‘old-fashioned’ appearance and expanding the displays to include, for example, its first mounted vertebrate skeleton. An aggressive collections policy involves establishing a...

On present day islands and past distributions
Provedor de dados: 16
Autores: Renema, W.
Southeast Asia, and especially the Philippines-Indonesia-Papua New Guinea Archipelago, harbours the world’s highest marine diversity. This region also had a complex geological history. This raises the question whether these two attributes are related and, if so, how. To locally build high species richness in a region, the balance between speciation/immigration and extinction/exturpation should be positive over at least part of its geologic history.

Towards modern petrological collections
Provedor de dados: 16
Autores: Kriegsman, L.M.
Petrological collections result from sampling for academic research, for aesthetic or commercial reasons, and to document natural diversity. Selection criteria for reducing and enhancing collections include adequate documentation, potential for future use, information density, time and money invested in specimens, and spatial and financial constraints. Application of these criteria to the voluminous (c. 300,000 samples) rock collections of the University of Amsterdam, led to partial acquisition by the Nationaal Natuurhistorisch Museum in Leiden (Naturalis) late in 2002. Selected items included: (i) historical collections; (ii) material from former overseas domains; (iii) material from poorly accessible areas; (iv) material useful for research at the museum...

Preliminary investigation on the Pleistocene/Holocene Sea-Level Changes along the Coastline of Tanzania, with reference to Unguja and Pemba  Islands
Provedor de dados: 20
Autores: Nyandwi, N.; Muzuka, A.N.N.; Shaghude, Y.W.
Along the coast of Tanzania, coral reefs, marine terraces and beach ridges are among the most important geomorphological features indicative of the Pleistocene/Holocene sea level changes. Three major terrace units can easily be identified on the mainland coast, namely, Mtoni (youngest), Tanga and Sakura (oldest). Three terrace units have also been identified on the Islands of Unguja and Pemba. On the basis of the difference in the terrace elevations between the two terrace systems it is postulated that the marine terraces on the islands probably represent minor fluctuations of sea level, rather than major phases of sea level fluctuation. A sand beach on the seaward side and several sand ridges on the landward side represent the Recent phase. The oldest...

Apatite Fission Track Analysis of Sites 959 and 960 on the Transform Continental Margin of Ghana, West Africa
Provedor de dados: 20
Autores: Carter, A.; Clift, P.D.; Hurford, A.J.
Four samples of sandstone from deformed Aptian–Albian sediments and their less deformed Turonian cover at Sites 959 and 960 on the Côte d’Ivoire-Ghana Marginal Ridge yielded sufficient apatite for fission track analysis. Reduced mean track length values of 12.42 ± 0.16 μm to 13.67 ± 0.11 μm indicate that measured central ages, which range from 88 ± 4 Ma to 113 ± 4 Ma, have undergone partial resetting and are therefore apparent ages. Stochastic modeling of the fission track age and length parameters indicate that the samples have a strong predepositional signal, slightly modified by minor levels of prolonged postdepositional annealing (maximum temperatures &lt;80°C). The preserved provenance-related signal records cooling through the apatite partial...

Mobility and immobility of mid-ocean ridges and their implications to mantle dynamics
Provedor de dados: 20
Autores: Masalu, D.C.P.
In the past two decades, the mobility of mid-ocean ridges relative to the mantle (absolute migration) has been correlated with major observable features, such as spreading asymmetry and asymmetry in the abundance of seamounts. The mobility of mid-ocean ridges is also thought to be an important factor that influences the diversity of ridge-crest basalts. However, this mobility has not yet been defined and mapped. The absolute migration of global mid-ocean ridges since 85 Ma has been computed and mapped. Global mid-ocean ridges have migrated extensively at varying velocities during that period. Presently, the fast-migrating ridges are the Pacific- Antarctic, Central Indian Ridge, Southeast Indian Ridge, Juan de Fuca, Pacific-Nazca, Antarctic-Nazca, and the...

As pan of the EROS-2000 project (European River Ocean Systems),sediment samples were collected in the North Western basin of the Mediterranean Sea in May 1990. In these samples trace and/or majorelements were determined to advance the knowledge about theconcentration, sources and cycles of natural and anthropogenicconstituents in coastal areas. Three fractions were determined: the porewater fraction whichcontains all dissolved elements the leachable fraction which containsall easily available elements and the residual fraction which containsthe strongly bound elements in the sediments. The results show thatthe investigated area can be separated into five "sub-areas" which aredifferent in element concentration, leachable fraction andsedimentary composition....

Late Weichselian to Holocene Evolution of the Maputo Bay, Mozambique
Provedor de dados: 20
Autores: Mugabe, J.; Achimo, M.; Cuamba, F.; Haldorsen, S.
During the Quaternary the volume of the world’s oceans fluctuated, with sea level falls as the water has been incorporated into polar and high latitude ice sheets, and sea level rise as these have subsequently melted. Sea-level lowstands were therefore related to the Pleistocene glaciations, while high-stands correlate with interglacials. In general the climate variations in Africa shows a simple relation: Cold or cool climates are associated with dry episodes and warm climates are associated with wet episodes. This applies to the major Milankovich driven glacials and interglacials, as well as to short-lived intervals related to sun spot activities. The reconstruction of palaeoshorelines in the Maputo Bay, and the climate around the Maputo Bay is based on...

Thermal Anomalies, Updoming And Non-Marine Sequence Stratigraphy: A Case History From The Karoo Basin, South Africa
Provedor de dados: 20
Autores: Turner, B.R.
The Karoo Basin is one of the most extensively exposed and well studied of all the major Gondwana basins along the southern margin of Gondwana. It has been modelled as a retroarc foreland basin in which the basin-fill has been divided into 1st, 2nd and 3rd order depositional sequences, bounded by unconformities and/or abrupt facies changes (Catuneanu et al., 1999), and linked to specific tectonic events in the adjacent orogen to the south. In contrast, Johnson et al. (1997) state that ?no significant unconformities are known to exist within the [Karoo] basin, with the possible exception of the one at the base of the Upper Triassic Molteno Formation?. The foreland basin model further suggests that foreland basin tectonics influenced Karoo stratigraphic...

Genesis and Classification of Soils from Subtropical Mountain Regions of Southern Brazil
Provedor de dados: 90
Autores: Dortzbach,Denilson; Pereira,Marcos Gervasio; Anjos,Lúcia Helena Cunha dos; Fontana,Ademir; Silva Neto,Eduardo de Carvalho.
ABSTRACT Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the location along the altitudinal gradient. The goal of this study was to characterize and classify the soil, evaluate soil distribution, and determine the interactive effects of soil-forming factors in the subtropical mountain regions in Santa Catarina state. Soil samples were collected in areas known for wine production, for a total of 38 modal profiles. Based on morphological, physical, and chemical...

ABSTRACT The study area is located in the state of Minas Gerais, Brazil, among the municipalities of Pedro Leopoldo, Matozinhos, and Sete Lagoas, with Velhas River as the eastern boundary. It is located in the São Francisco Craton, where carbonated argillo-arenaceous sediments are emplaced giving origin to the Bambuí Group, in the São Francisco Basin. Despite the geological knowledge previously developed, the region needs work on integration and detailing of such information. For this reason, the main objective was to contribute to the quality of the geologic cartography, the spatial distribution, and the structural framework geometry. Thus, geologic mapping, aerial photography interpretation, and evaluation of 270 lithologic well profiles were carried...
