             abstract = "In this work we explore a particular characteristic of some ICMEs 
                         which is the presence of very high intensity magnetic field peaks 
                         in particular in their shock-sheath regions. These magnetic field 
                         peaks are short duration when compared to the total extent of the 
                         ICME but they often drive intense geomagnetic storms. In this 
                         work, we study the magnetic field and plasma observations obtained 
                         at the L1 point from 1997 to present. To evaluate the geomagnetic 
                         impact we use the Disturbance Storm-time Dst index. We also study 
                         the solar origins of these events when solar observations are 
                         available. In the context of Space Weather, it is known that shock 
                         sheath fields are very important origins of energy injection in 
                         the Earths magnetosphere. Their forecasting though is still very 
                         challenging.",
