| Abstract | We present high-resolution marine paleoclimate records obtained from sediment cores retrieved along three profiles extending from the Saudi Arabian coast to the central axis of the northern Red Sea during R/V METEOR cruise M44/3 in spring 1999. Because of its restricted, desert surrounded location, the northern Red Sea suf- fered extreme oceanographic changes in the past, resulting in an amplification of pale- oclimatic signals in the marine sediments. The continuous deposition of wind-blown and fluvially transported terrigenous material provides a high temporal resolution of changes in the aridity of the adjacent continents. Such changes are documented by in- dependent indicators, i.e., variations of the bulk-sediment chemistry (Fe- and Ti- content determined by profiling XRF measurements) and magnetic susceptibility. Synchronously, changes in the marine environment are reflected by variations in the carbonate content (i.e., Ca- and Sr-intensities). Our records provide evidence of a strong coupling of both aridity changes in the Near East and paleoceanographic condi- tions in the northern Red Sea to global climate and sea level changes as well as varia- tions in the monsoonal system. |
