In January 2013, under the aegis of the Nextdata project (http://www.nextdataproject.it/), 50 metres of Holocene sediment were piston cored from Tyrrhenian Sea sites near the mouth of the Volturno River in southern Italy. The sediments can be dated accurately using tephrastratigraphic and magnetostratigraphic techniques, and record varying influences from regional climate and local terrigenous inputs. We present the first results from environmental magnetic analyses of the cores using hysteresis loops, remanent coercivity spectra, first-order reversal curves, and thermomagnetic experiments, providing a high-resolution record of environmental change from this sector of the Mediterranean, and demonstrating the ability of enviromagnetic techniques to reconstruct records of competing controls in rapidly deposited coastal sediments.
