Abstract

At Aqaba in the Northern Gulf of Aqaba, Red Sea, the stable oxygen isotope record of a Parités lutea coral colony was studied. From a vertical and a horizontal core two parts from the base of the colony (10 years of coral growth), and two parts from the living surface (12 years of coral growth) were analysed with a monthly sampling resolution. The results show that seasonality of sea surface temperatures (SST) in the northern Gulf of Aqaba has increased since the early 19th century, mainly due to higher summer temperatures. 8"O-ratios indicate that SST increased by at least 1.3°C. Horizontal and vertical cores display different variations in the modern parts, probably caused by the very shallow water depth of the youngest part of the vertical core.
