The Educational Seismological Project (EduSeis) is a scientific and educational project, the main aim of which
 is the development and implementation of new teaching methodologies in Earth Sciences, using seismology as
 a vehicle for scientific learning and awareness of earthquake risk. Within this framework, we have recently been
 experimenting with new learning and information approaches that are mainly aimed at a high school audience.
 In particular, we have designed, implemented and tested a model of an e-learning environment in a high school
 located in the surroundings of the Mt. Vesuvius volcano. The proposed e-learning model is built on the EduSeis
 concepts and educational materials (web-oriented), and is based on computer-supported collaborative learning.
 Ten teachers from different disciplines and fifty students at the ITIS «Majorana» technical high school (Naples)
 have been taking part in a cooperative e-learning experiment in which the students have been working in small
 groups (communities). The learning process is assisted and supervised by the teachers. The evaluation of the results
 from this cooperative e-learning experiment has provided useful insights into the content and didactic value
 of the EduSeis modules and activities. The use of network utilities and the «Learning Community» approach
 promoted the exchange of ideas and expertises between students and teachers and allowed a new approach to the
 seismology teaching through a multidisciplinary study.Date

East Greenland Caledonides: stratigraphy, structure and geochronology: Lower Palaeozoic stratigraphy of the East Greenland CaledonidesSmith, M. Paul; Rasmussen, Jan Audun; Robertson, Steve; Higgins, A.K.; Leslie, A. Graham (Geological Survey of Denmark and Greenland, 2004-12-01)The Lower Palaeozoic stratigraphy of the East Greenland Caledonides, from the fjord region of North-East Greenland northwards to Kronprins Christian Land, is reviewed and a number of new lithostratigraphical units are proposed. The Slottet Formation (new) is a Lower Cambrian quartzite unit, containing Skolithos burrows, that is present in the Målebjerg and Eleonore Sø tectonic windows, in the nunatak region of North-East Greenland. The unit is the source of common and often-reported glacial erratic boulders containing Skolithos that are distributed throughout the fjord region. The Målebjerg Formation (new) overlies the Slottet Formation in the tectonic windows, and comprises limestones and dolostones of assumed Cambrian–Ordovician age. The Lower Palaeozoic succession of the fjord region of East Greenland (dominantly limestones and dolostones) is formally placed in the Kong Oscar Fjord Group (new). Amendments are proposed for several existing units in the Kronprins Christian Land and Lambert Land areas, where they occur in autochthonous, parautochthonous and allochthonous settings.

The influence of global warming in Earth rotation speedR. Abarca del RioThe tendency of the atmospheric angular momentum (AAM) is investigated using a 49-year set of monthly AAM data for the period January 1949-December 1997. This data set is constructed with zonal wind values from the reanalyses of NCEP/NCAR, used in conjunction with a variety of operationally produced AAM time series with different independent sources and lengths over 1976-1997. In all the analyzed AAM series the linear trend is found to be positive. Since the angular momentum of the atmosphere-earth system is conserved this corresponds to a net loss of angular momentum by the solid earth, therefore decreasing the Earth rotation speed and increasing the length of day (LOD). The AAM rise is significant to the budget of angular momentum of the global atmosphere-earth system; its value in milliseconds/century (ms/cy) is +0.56 ms/cy, corresponding to one-third of the estimated increase in LOD (+1.7 ms/cy). The major contribution to this secular trend in AAM comes from the equatorial Tropopause. This is consistent with results from a previous study using a simplified aqua-planet model to investigate the AAM variations due to near equatorial warming conditions. During the same time interval, 1949-1997, the global marine + land-surface temperature increases by about 0.79 °C/cy, showing a linear correspondence between surface temperature increase and global AAM of about 0.07 ms per 0.1 °C. These results imply that atmospheric angular momentum may be used as an independent index of the global atmosphere's dynamical response to the greenhouse forcing, and as such, the length of day may be used as an indirect indicator of global warming.<br><br><b>Key words. </b>Meteorology and atmospheric dynamics (general circulation) · Geodesy

Calculation of the parameter 'deflection' in a new theory of the Earth’s magnetic fieldA. de Paor; E. Burke (Copernicus GmbH on behalf of the European Geosciences Union (EGU) and the American Geophysical Union (AGU), 2002-01-01)In a recent paper on the theory of the Earth's magnetic field and key features of Sunspot activity (de Paor, 2001), a central role in the calculation of secular variations of the geomagnetic field was played by a newly-introduced parameter called the deflection (abbreviated <i>def </i>). In this note, the significance of def is elucidated and the method used to calculate it is explained.
