  Information - MPRG8 Magnetism, Environment and Climate : a session dedicated to the memory of Bill GOREE

Event Information
This session has two independent goals: 1) evaluate available evidences of possible links between the geomagnetic field variations and paleoclimate or orbital fluctuations and envisage their mechanisms; 2) Assess recent advances in soil and sediments magnetic characterization and their relevance for detection of (paleo-)climate and (paleo-) environmental changes.
1) Paleomagnetic and archeomagnetic records can be compared with paleoclimatic variations records at the scales of few millennia to one million year. The validity of the signals, their resolution and their temporal coverage progressively met the criteria required for evaluating the degrees of correlations and the phase relationships.
2) Rock-magnetism offers high sensitivity and high-resolution tools to decipher lithological and geochemical changes of sediments and soils, linked with past climatic and environmental changes. From single parameter, high-resolution rock-magnetic characterizations to multi-proxy parameter networks characterizing mixtures of metal oxides and/or sulphides, the rock-magnetic methods interact with other methods (rock physics, geochemistry, paleobiology…), for a better qualification and when possible a quantification of paleoclimate variations at the local, regional or global scale.

This session is dedicated to the memory of Bill GOREE who unexpectedly died in July 2007. Since the 70'ies, as Physical ingeneer, Bill developped and promoted, together with Bill Goodman (the other "G"), the most efficient and precise instruments to measure weak remanent magnetizations, with the best stability, the best screening and the best possible liquid Helium consumption.
The paleomagnetic and rock-magnetic community is honored to acknowldege this great achievement made with such competence and permanent kindness and humanity.
