[From The Landmap Project: Introduction, "http://www.landmap.ac.uk/background/intro.html"]

 A joint project to provide orthorectified satellite image mosaics of Landsat,
 SPOT and ERS radar data and a high resolution Digital Elevation Model for the
 whole of the UK. These data will be in a form which can easily be merged with
 other data, such as road networks, so that any user can quickly produce a
 precise map of their area of interest.

 Predominately aimed at the UK academic and educational sectors these data and
 software are held online at the Manchester University super computer facility
 where users can either process the data remotely or download it to their local
 network.

 Please follow the links to the left for more information about the project or
 how to obtain data or access to the radar processing system at MIMAS. Please

In English: The main activity carried out in the Antarctic campaign in the Marambio Island, consisted of the geo-positioning of relevant topographical and geologic elements of the James Ross Island for support of the geologic mapping.

The positioning of fourteen reference points was carried out with the help of two MAGELLAN 5000-PRO GPS outfits with external antennas and sub-metric kits, and differential GPS methods were used. The registration of the data was carried out in portable computers.

The fixed station of measure was located in the Marambio Island, in a point previously positioned with regard to a geodesic vertex settled by the U. S. Geological Survey. The mobile station was transported by two helicopters of the Argentinean Air Force to the target points in the James Ross Island.

At the same time that GPS measurements were made, a sampling of rocks of the James Ross Volcanic Group was carried out for the petrologic and geochemical study of this volcanic unit.

They were also carried out analysis of olivines, clinopyroxenes, ore minerals and zeolites by means of electronic microprobe. In this first stage of the studies, it is important to highlight the fact that the magnesium content of ilmenites is relatively high and that the contents of titanium of the clinopyroxenes is moderate and similar to the one observed in this mineral in typica] alkaline basalt series.

En Espanol: La actividad fundamental desarrollada en la campana en la Isla de Marambio consistio en la georreferenciacion de elementos topograficos y geologicos en la isla James Ross, para el apoyo de la cartografia geologica. Se realizo el posicionamiento de catorce puntos mediante tecnicas de GPS diferencial, utilizando dos equipos MAGELLAN 5000-PRO, con antenas externas y kits submetricos efectuandose registros de los datos en ordenadores portatiles.

Se establecio una estacion de medida en la Isla de Marambio, georreferenciada con respecto a un vertice geodesico situado en la isla y posicionado por el U.S. Geological Survey, mientras que la estacion movil, era desplazada a los puntos de medida en la isla James Ross en los helicopteros de las Fuerzas Aereas Argentinas de la Base de Marambio, realizandose alli las mediciones correspondientes, asi como los balizamientos y las fotografias aereas para la identificacion precisa de los puntos.

Simultaneamente a la campana de medidas y aprovechando los desplazamientos, se realizo una toma de muestras de rocas volcanicas del Grupo James Ross con objeto de efectuar estudios petrologicos y geoquimicos sobre este grupo volcanico.

Se realizaron analisis mediante microsonda electronica de olivinos, cliropiroxenos, ceolitas y minerales opacos, siendo de destacar en esta primera fase de los estudios, los contenidos relativamente elevados de magnesio en las ilmenitas de las rocas subvolcanicas y el que los contenidos de titanio de los cliropiroxenos es moderado y equivalente al de los otros piroxeno titanados de series basalticas alcalinas tipicas
