    Abstract: Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) data acquired between January 1993 and December 1996 from the SPOT‐2, SPOT‐3, and TOPEX/Poseidon satellites have been analyzed to determine velocities for 45 sites on eight major tectonic plates. For 28 sites far from deformation zones, the velocity estimates agree with plate model predictions. Least squares computation of poles of rotation, which model the plate motions, shows that for Eurasia, Africa, Pacific, and South America plates, the agreement is better with NUVEL‐1, while for Australia, Antarctica, Nazca, and North America plates the DORIS Euler vectors are closer to NTJVEL‐1A. In general, DORIS results do not differ significantly from other space geodetic techniques determinations but provide better estimates for plates poorly or inhomogeneously covered by Global Positioning System (GPS), Very Long Baseline Interferometry (VLBI) and Satellite Laser Ranging (SLR) networks, such as Africa. The DORIS coverage of this plate allows discussion of intraplate deformations due to the motion of the eastern Africa part which constitues the Somalia plate. Sites located in deformation zones, such as western Eurasia boundaries, central Asia, southwestern America coast, South East Asia, show motion with respect to their own plates. Comparisons with other geodetic measurements for colocated stations, or with regional geodynamical models, show the interest of DORIS in active zones where global plate models are not valid.

    Abstract: The broad depth and geoid anomalies associated with 23 hotspot swells in oceanic areas have been analyzed. Maximum height and geographical extent of the topographic swell, and of the geoid anomaly as well, have been measured for each hotspot. The results indicate a clear increase of the topographic swell height with age of the underlying lithosphere, from values in the range 300–500 m at young ages to values in the range 1500–2000 m at ages larger than 100 Ma. The geoid anomaly amplitude also increases with plate age from nearly zero close to mid‐ocean ridges, to 6–8 m over old plates. On the other hand, the geographical extent of the swell does not show any clear relationship with plate age. The mean lateral extent of swells range from 1000 to 1500 km. Swells located close to spreading ridges show a significant non zero depth anomaly but are associated with negligeable geoid signal. These results complete those of a previous study where the apparent compensation depth of oceanic hots pot swells was showed to increase linearly with the square root of plate age and coincide roughly with the base of the thermal lithosphere. This trend may either be interpreted in terms of lithospheric thinning or dynamical support. Besides both seem necessary to explain the observed bathymetry, in proportion evolving with aging of the lithosphere.

    Abstract: We present results for the M 2 and O 1 ocean tides based on the Starlette satellite orbit analyses from which the tidal acceleration of the moon is derived. The solution for M 2 is consistent with previous satellite solutions; for O 1 we find a phase lag which is approximately zero. The uncertainty is still large, but there is an indication that the tidal dissipation at the O 1 frequency is small. Using the weighted mean value of the best satellite solutions gives = −21.32 ± 1.25 arc sec/(century) 2 for the total dissipation in the earth at the M 2 frequency. In principle, comparison between derived from satellite solution and derived from numerical models gives the amount of dissipation in the solid earth, but uncertainties are still too large to give a reliable estimate of the tidal mantle Q .

    Abstract: One of AGU's major programs is its honors program, which includes the Union medals and awards, fellowships, and section and focus group awards. The program seeks to recognize outstanding contributions made by AGU members and other individuals to the advancement of the Earth and space sciences; service to the community; and excellence in education, outreach, and science journalism. The International Award, the most recent addition to the Union's honors program, this year was presented for the third time, and nominations are being sought for the 2010 award. This award for international research cooperation was established to recognize an individual scientist or a small team for making an outstanding contribution to furthering the Earth and space sciences and using science for the benefit of society while laboring under adverse circumstances with limited resources in less favored nations.
