  • Il prodotto e' un articolo scientifico che presenta e discute i risultati di una analisi effettuata su carotaggi marini del Mar Ionio e datati con grande precisione. Dall'analisi si ottengono risultati sull'illuminazione della superficie marina nel periodo 590-1979 AD con una risoluzione di 3,87 anni. Il risultato costituisce una estensione di una precedente serie temporale pubblicata sula stessa rivista. (literal)

Abstract
  • We present measurements and data analysis of the oarbon stable isotopes (delta^13C) in the planktonic Globigerinoides ruber extracted from the GT9O/3 shallow water lonian sea core, dated with high precision. It is commonly accepted that delta^13C variations in symbiontic foraminifera mainly record the effects of productivity and of photosynthetic activity, varying with the ambient light level. Therefore from this time series we can deduce information on the sea surface illumination at the time of the planktonic foraminifera growth. The profile (359 points) covers the period 590-1979 AD, with a resolution of 3.87 years and it is an extension of the time series (215 points) previously published in this journal. The spectral analysis of the longer time series confirms the presence of the 11 y signal, with amplitude —0.08 per mille (peak-to-trough), found in the shorter time series in phase with the sunspot solar cycle; furthermore it shows the presence of two centennial cycles of 100 and 200 years, with amplitude 0.08 per mille and 0.02 per mille respectively. These components are identified at high significance level by Monte Carlo singular spectrum analysis (MC-SSA). A comparison between the delta^13C profile and the historical aurorae series (600-1500 AD) shows that the long-term delta^13C variations are at least partially generated by the solar activity modulation and in phase with the solar output, as represented by the solar wind interaction with the magnetosphere.
