Abstract - We present DAPHNE, a client/server Java software that acquires data and serve to CLIENTS on the Internet. The software was tested on Load Cell tranducers (cable layout strength) and GPS (NMEA, TSIP) on board of R/V OGS-Explora. A particular application deals with the accurate timestamp of events, by using the Acutime^TM GPS receivers, especially useful for refraction seismic. Sommario - Viene presentato DAPHNE, un software in modalita' client/server per la acquisizione di dati e la loro distribuzione su Internet. Il software e' stato testato con Celle di carico (tensione di cavi) e GPS (NMEA,TSIP) a bordo della nave oceanografica OGS-Explora. Una applicazione particolare riguarda la registrazione di eventi ad alta accuratezza temporale, tramite il ricevitore GPS Acutime^TM.
