Abstract

The stable isotopic composition of scleractinian corals (Porites sp.), two recent and one fossil, from
the Egyptian Red Sea coast was studied. The oxygen isotope record proves the assumption that recent sea surface
temperatures are comparable to the time of last sea level highstand in Eemian (stage 5e, 125,000 yBP).
Deposition of high-density and low-density bands in respect to season shows the sanre patterns as today with
high-density band depositior in winter (low water temperatures) and low-density band deposition in summer
(high water temperatures). 6180 is negatively correlated with 613C with a shift in phase of t to Z months. Thus, a
coupling of carbon isotopes to light intensity and oxygen isotopes to water temperature is suggested. To get an
overview on seasonal patterns of stable isotope composition a sampling technique with a resolution of four samples
per year is of sufficient precision.
