La creación del espacio poético en Momento de Simetría (1973) de Arturo Carrera y en sus manuscritos : Una constante formación de la materia escrituaria

El trabajo explora, desde los aportes de la crítica genética y literaria, la construcción del espacio poético y sus espacios creativos de escritura. Para ello se cuenta con manuscritos del poeta argentino Arturo Carrera, pertenecientes a su segunda obra édita, Momento de simetría [1973]. Partiendo de una referencia astronómica existente en el poemario se revisa lo dicho por la crítica literaria argentina sobre la obra del autor así como también la posibilidad de leer el mapa poético y sus manuscritos como imágenes estéticas en suspensión. Por este motivo, el trabajo cuenta además con un Anexo (en CD) con las imágenes digitales del Archivo Momento de simetría y sus correspondientes transcripciones, a fin de que el lector pueda ir y venir del texto a las imágenes -y viceversa- y construir dicho recorrido

Gestión del paisaje y ordenamiento territorial : Abordajes conceptuales y metodológicos

El propósito de la ponencia es elaborar un panorama sobre la relevancia de la gestión del paisaje dentro del ordenamiento territorial, un tema cuya discusión ha emergido en los últimos años y en base al cual se han desarrollado numerosas normativas y técnicas dentro del contexto europeo y norteamericano. El proceso de globalización ha intensificado las dinámicas homogeneización urbana de dispersión territorial, y especialización funcional. En Europa y EEUU, como respuesta a éstas dinámicas, se han impulsado estrategias de gestión territorial sobre la base del ordenamiento del paisaje. Las acciones emprendidas responden a la instrumentación de políticas, metodologías e intervenciones impregnadas de una concepción de paisaje entendido como atributo de la totalidad del territorio; referido tanto a los espacios singulares y/o destacados como a los cotidianos y degradados. Desde el diagnóstico urbano y territorial comienzan a implementarse instrumentos que profundizan en el conocimiento del territorio desde este enfoque. El establecimiento de acuerdos internacionales dirigidos a impulsar la gestión del paisaje, ha promovido el desarrollo de legislaciones, instrumentos y proyectos que sitúan al paisaje como un componente destacado dentro del ordenamiento territorial y la planificación urbanística, que se establecen dentro de dos líneas claramente definidas: una línea propositiva en la que el paisaje es considerado como reactivador de territorios patrimoniales y una línea normativa, integrada por leyes que intentan guiar la gestión del territorio asociado a la valoración del paisaje. Las experiencias desarrolladas en Europa y en Norteamérica en materia de gestión del paisaje Invitan a pensar en estrategias adecuadas al escenario latinoamericano. Puede verificarse que dichas estrategias presentan cierto nivel de transferencia a otros contextos, dejando en claro que es posible utilizar el concepto de paisaje para dar respuesta a cuestiones de ordenamiento territorial en contextos con menor nivel de desarrollo que el europeo, sin dejar de tener en cuenta que las demandas son diferentes. De esta manera, queda por responder cómo implementar este tipo de proyectos dentro del contexto latinoamericano, resolviendo problemáticas que exceden la escala de los países desarrollados, y donde el paisaje puede constituirse como una herramienta de reconocimiento de la particular identidad local, además de cumplir un significativo rol en el aspecto medioambiental

Terrain model of the eastern slope of the Porcupine Seabight (50 m grid size)

The topography of the eastern margin of the Porcupine Seabight was surveyed in June 2000 utilizing swath bathymetry. The survey was carried out during RV Polarstern cruise ANT XVII/4 as part of the GEOMOUND project. The main objective was to map and investigate the seafloor topography of this region. The investigated area contains a variability of morphological features such as deep sea channels and giant mounds. The survey was planned and realized on the basis of existing data so as to guarantee the complete coverage of the margin. In order to achieve a resolution of the final digital terrain model (DTM) that meets the project demands, data processing was adjusted accordingly. The grid spacing of the DTM was set to 50 m and an accuracy better than 1% of the water depth was achieved for 96% of the soundings.

Shape-invariant multibeam backscatter data of the eastern slope of the Porcupine Seabight (50 m grid size)

In this study multibeam angular backscatter data acquired in the eastern slope of the Porcupine Seabight are analysed. Processing of the angular backscatter data using the 'NRGCOR' software was made for 29 locations comprising different geological provinces like: carbonate mounds, buried mounds, seafloor channels, and inter-channel areas. A detailed methodology is developed to produce a map of angle-invariant (normalized) backscatter data by correcting the local angular backscatter values. The present paper involves detailed processing steps and related technical aspects of the normalization approach. The presented angle-invariant backscatter map possesses 12 dB dynamic range in terms of grey scale. A clear distinction is seen between the mound dominated northern area (Belgica province) and the Gollum channel seafloor at the southern end of the site. Qualitative analyses of the calculated mean backscatter values i.e., grey scale levels, utilizing angle-invariant backscatter data generally indicate backscatter values are highest (lighter grey scale) in the mound areas followed by buried mounds. The backscatter values are lowest in the inter-channel areas (lowest grey scale level). Moderate backscatter values (medium grey level) are observed from the Gollum and Kings channel data, and significant variability within the channel seafloor provinces. The segmentation of the channel seafloor provinces are made based on the computed grey scale levels for further analyses based on the angular backscatter strength. Three major parameters are utilized to classify four different seafloor provinces of the Porcupine Seabight by employing a semi-empirical method to analyse multibeam angular backscatter data. The predicted backscatter response which has been computed at 20° is the highest for the mound areas. The coefficient of variation (CV) of the mean backscatter response is also the highest for the mound areas. Interestingly, the slope value of the buried mound areas are found to be the highest. However, the channel seafloor of moderate backscatter response presents the lowest slope and CV values. A critical examination of the inter-channel areas indicates less variability within the estimated three parameters.

Seagrass time-series analysis products, in Moreton Bay, Australia, with links to GeoTIFFs

The spatial and temporal dynamics of seagrasses have been well studied at the leaf to patch scales, however, the link to large spatial extent landscape and population dynamics is still unresolved in seagrass ecology. Traditional remote sensing approaches have lacked the temporal resolution and consistency to appropriately address this issue. This study uses two high temporal resolution time-series of thematic seagrass cover maps to examine the spatial and temporal dynamics of seagrass at both an inter- and intra-annual time scales, one of the first globally to do so at this scale. Previous work by the authors developed an object-based approach to map seagrass cover level distribution from a long term archive of Landsat TM and ETM+ images on the Eastern Banks (~200 km**2), Moreton Bay, Australia. In this work a range of trend and time-series analysis methods are demonstrated for a time-series of 23 annual maps from 1988 to 2010 and a time-series of 16 monthly maps during 2008-2010. Significant new insight was presented regarding the inter- and intra-annual dynamics of seagrass persistence over time, seagrass cover level variability, seagrass cover level trajectory, and change in area of seagrass and cover levels over time. Overall we found that there was no significant decline in total seagrass area on the Eastern Banks, but there was a significant decline in seagrass cover level condition. A case study of two smaller communities within the Eastern Banks that experienced a decline in both overall seagrass area and condition are examined in detail, highlighting possible differences in environmental and process drivers. We demonstrate how trend and time-series analysis enabled seagrass distribution to be appropriately assessed in context of its spatial and temporal history and provides the ability to not only quantify change, but also describe the type of change. We also demonstrate the potential use of time-series analysis products to investigate seagrass growth and decline as well as the processes that drive it. This study demonstrates clear benefits over traditional seagrass mapping and monitoring approaches, and provides a proof of concept for the use of trend and time-series analysis of remotely sensed seagrass products to benefit current endeavours in seagrass ecology.

A geomorphological seabed classification for the Weddell Sea, Antarctica, with links to ArcGIS project files

Sea floor morphology plays an important role in many scientific disciplines such as ecology, hydrology and sedimentology since geomorphic features can act as physical controls for e.g. species distribution, oceanographically flow-path estimations or sedimentation processes. In this study, we provide a terrain analysis of the Weddell Sea based on the 500 m × 500 m resolution bathymetry data provided by the mapping project IBCSO. Seventeen seabed classes are recognized at the sea floor based on a fine and broad scale Benthic Positioning Index calculation highlighting the diversity of the glacially carved shelf. Beside the morphology, slope, aspect, terrain rugosity and hillshade were calculated. Applying zonal statistics to the geomorphic features identified unambiguously the shelf edge of the Weddell Sea with a width of 45-70 km and a mean depth of about 1200 m ranging from 270 m to 4300 m. A complex morphology of troughs, flat ridges, pinnacles, steep slopes, seamounts, outcrops, and narrow ridges, structures with approx. 5-7 km width, build an approx. 40-70 km long swath along the shelf edge. The study shows where scarps and depressions control the connection between shelf and abyssal and where high and low declination within the scarps e.g. occur. For evaluation purpose, 428 grain size samples were added to the seabed class map. The mean values of mud, sand and gravel of those samples falling into a single seabed class was calculated, respectively, and assigned to a sediment texture class according to a common sediment classification scheme.

Map of Lewis-Glacier - Mt. Kenya 1983 (pdf 600 kB)

In February of 1983 a new terrestrial photogrammetric survey of Lewis Glacier (0° 9' S) has been made, from which the present topographic map has been produced in a scale of 1:5000. Simultaneously a survey of 1963 was evaluated giving a basis for computations of area and volume changes over the 20 year period: Lewis Glacier has lost 22 % of its area and 50 % of its volume. Based on maps and field observations of moraines 10 different stages were identified. Changes of area and volume can be determined for the periods after 1890, two older, undated stages are presumed to be of Little Ice Age-origin. Moderate losses from 1890 to 1920 were followed by strong, uninterrupted retreat up to present. In this respect Lewis Glacier behaves as all other equatorial glaciers that were closer examined. Compared to alpine glaciers the development was similar up to 1950. In the following years, however, the glaciers of the Alps gained mass and advanced while Lewis Glacier experienced its strongest losses from 1974 to 1983.
