Iv. Ivanov, OSCILLATIONS IN THE LEVELS OF THE CASPIAN-SEA AND ARAL-SEA AND THE SUPERSECULAR PERIODICITY OF SOLAR-ACTIVITY DURING THE LAST 5000 YEARS, Biofizika, 43(4), 1998, pp. 697-700
Transgressions of the Caspian Sea took place during epochs of the alte
rnating normal and minimal solar activity, regressions of it occured d
uring epochs of the alternating normal and maximal solar activity. Tra
nsgressions of the Aral Sea were not found to belong to periods both o
f minimal or normal solar activity, but regressions happened during ep
ochs of its alternating normal and maximal values of solar activity.
