| Abstract |
Polynological data from sediment cores taken from E1 Junco crater lake on San Cristobal Island led to the recognition of stratigraphical fluctuations resulting from the water budget in the crater. The results show that the crater was dry between at least 34,000 and 10,000 yr B.P. A new mechanism that could explain this general dryness is suggested. It is suggested that a dry climate in the Galapagos Island could result from changes in the intensity of the southern trade wind rather than from the shifting and continuing existance of the ITCZ in the Northern Hemisphere. |
