Abstract
The profile of thermoluminescence (TL) has been measured in the Ionian shallow-water core GT89-3 with a resolution of 3.096 years (corresponding to a sampling interval of 2 mm) during the last 1800 years. A similar TL record was previously obtained in the core GT14, taken from the same area, with a resolution of 3.87 years (corresponding to a sampling interval of 2.5 mm). We present here the comparison of the TL profiles. We confirm the presence of the centennial and the decennial cycles earlier identified in the TL signal, corresponding to cyclicities appearing to exist in the solar-activity records. We discuss the origin of the TL signal by comparison with the cosmogenic isotopes 14C and 10Be records.
