             abstract = "Interplanetary coronal mass ejections (ICMEs) are the 
                         interplanetary counterparts of coronal mass ejections observed at 
                         the Sun. These interplanetary structures differ from the ambient 
                         solar wind in many aspects, among them, their high intensity 
                         magnetic fields which can be observed either within their internal 
                         structure or at the associated shock-sheath region. In this work 
                         we examine the characteristics of intense ICME sheath magnetic 
                         fields observed during solar cycles 23 and 24. After careful 
                         inspection of all ICMEs observed in the vicinity of the Earth from 
                         1998 to 2017, we selected all the events in which ICME sheath 
                         fields were observed to possess higher intensities than the their 
                         corresponding ICME internal fields. This subset of events is of 
                         particular interest for space weather because sheath fields are 
                         among the main interplanetary origins of geomagnetic disturbances, 
                         in particular during the maximum and descending phase of the solar 
                         cycle. Preliminary analysis on the connections between this subset 
                         of ICMEs and their associated CMEs will be presented.",
