Abstract:
Coastal strandplains on Saaremaa Island, Estonia, contain a rich archive of past events, which are recorded as geomorphic and lithological indicators of reworking (erosional) and depositional (accretionary) phases. This study presents a new dataset of low-field bulk magnetic susceptibility (MS) values from coastal sands as a rapid means of characterizing the ferrimagnetic and paramagnetic fraction in morphosedimentary units related to cyclone Gudrun (January 2005). Combining spatial and temporal patterns in MS (e.g., >600 SI for most peaks) with granulometric and geophysical databases provides the basis for applying similar integrated approach to reconstructing past extreme coastal events.
