Four Represent Geodynamics Branch at 4th Oersted Team Meeting
Purucker, Sabaka, Taylor and Voorhies all attend, present at Copenhagen meeting

Four members of the Geodynamics Branch Geomagnetics Group were participants at the 4th Oersted International Science Team meeting in Copenhagen, Denmark on 23-27 September 2002. All four presented papers in different sessions. In addition, another member of the Branch was a co-author on a paper presented there.

Pat Taylor (with Kim, Potts, von Frese and Frawley) gave a poster on "Satellite altitude geopotential study of the Kursk Anomaly (KMA)" and was a co-author on a paper by Kim, von Frese, Park and Taylor "Utility of satellite magnetic observations for estimating near surface magnetic anomalies".

Coerte Voorhies had a paper "Narrow scale, weak field flow at the top of Earth’s core: evidence from Oersted, Magsat and secular variation".

Mike Purucker presented along with Sabaka, Olsen and Maus his paper "How have Oersted, CHAMP, and SAC-C improved our knowledge of the oceanic regions?"

Terry Sabaka chaired a session and also gave a paper with Olsen on the "Comprehensive Model- ing of the Earth's mag- netic field: current status and future pros- pects". A paper on the most recent field model appeared in publication last month.

Benoit Langlais, a post-doc from France working in the Geodynamics was a co-author on the paper by Hulot, Eymin, Langlais, Mandea and Olsen , "Small scale structure of the geo- dynamo inferred from Oersted and Magsat satellite data" which was presented by Hulot.
