Abstract
IP effects are to be expected in Tempest AEM data, similarly to other systems’. We carry out extensive synthetic modelling that confirms it. We then present modelling of IP in delivered B field data and show that an improved result is obtained compared to those obtained without taking IP into account. The recovered chargeability seems largely associated with a near surface response. We anticipate that IP modelling may produce more accurate results if applied to data that is differently processed.
