      Apologies for any cross-posting -


      Dear Colleague,


      The purpose of this message is to announce a session at the European

      Geophysical Union meeting in Vienna, 24--29 April 2005, entitled


         "Wavelet and time-frequency analysis in the earth sciences"


      The session is being organized by J.M. Lilly and S.C. Olhede. A detailed

      description of the session, preliminary list of solicited speakers, and

      some additional information are provided below.


      Wavelet analysis and related approaches provide powerful new tools for

      attacking problems involving statistical nonstationarity and coherent

      structures, both in time series and in two or three dimensional fields.

      Our goal is to bring together researchers involved with the development

      of new mathematical and statistical methods with others whose interests

      require, and provide the impetus for, such new approaches.  We would

      like to encourage colleagues in either of these two categories to submit



      Abstract submission is now open, with a deadline of January 21, about

      two months from now.


      Please feel free to forward this to other interested researchers.

      Session information for NP4.05


      Wavelet and time-frequency analysis in the earth sciences


         Convener: J.M. Lilly      Co-convener: S.C. Olhede

         Programme:  Nonlinear Processes in Geophysics


      Many natural processes of great interest are neither periodic nor

      stationary. Wavelet and time-frequency (or time-scale) analysis therefore

      holds much potential for earth scientists. Despite the vast array of new

      methods which have emerged over the past decade, there is substantial

      scope for broader application of these methods to real-world problems,

      as well as for the development of further mathematical tools to address

      outstanding physical questions.


      The purpose of this session is to survey the most promising methods for

      the earth sciences, and to highlight specific examples of practical

      applications. Several areas of special interest are:


        --- nonstationary stochastic modelling

        --- extraction of signals immersed in noise

        --- wavelet decompositions in two and three dimensions

        --- multiple-window methods.


      Statistical considerations are particularly encouraged.

      Details on the Vienna EGU 2005 meeting are available online at




      Information for this session (NP 4.05) is found by following the "Call for

      papers Programme" link followed by "Nonlinear Processes in Geophysics".

      Abstract submission is then handled online from this location.
