ICDP unites a growing, large science community of about 3000 individuals all over the world. This diverse Earth science community engaged in scientific drilling spans many very different fields of expertise whose protagonists do not communicate with each other automatically. Sharing information about the program and promoting interaction is therefore a must. ICDP carries out Town Hall meetings at international conferences such as AGU and EGU to inform the scientific drilling community about the status of the program and current or upcoming scientific drilling activities.
