Annotated record of the detailed examination of Mn deposits from JAPANYON Expedition stations

The cores described in this report were taken on JAPANYON Expedition in June-September 1961 by Scripps Institution of Oceanography from, the R/V Spencer F. Baird. A total of 85 cores and dredges were recovered and are available at Scripps for sampling and study. The coring sites are all in the eastern tropical central Pacific.

Stable oxygen isotope data and geophysical measurements from Red Sea of core M174/Kl11

To settle debate on the timing of sea level fluctuations during marine isotope stage (MIS) 3, we present records of d18O ruber (sea level proxy) and magnetic susceptibility from the same samples within the single sediment archive (i.e., "coregistered") of central Red Sea core GeoTü-KL11. Core-scanning X-ray fluorescence and environmental magnetic data establish the suitability of magnetic susceptibility as a proxy for eolian dust content in Red Sea sediments. The eolian dust data record similar variability as Greenland d18O ice during early to middle MIS 3, in agreement with previous observations that regional Arabian Sea climate fluctuated with a timing similar to that of Greenland climate variations. In contrast, the sea level record fluctuates with a timing similar to that of Antarctic-style climate variations. The coregistered nature of the two records in core KL11 unambiguously reveals a distinct offset in the phase relationship between sea level and eolian dust fluctuations. The results confirm that sea level rises, indicated by shifts in Red Sea d18O ruber to lighter values, occurred during cold episodes in Greenland during early to middle MIS 3. This indicates that the amplitudes of the reconstructed MIS 3 sea level fluctuations would not be reduced by inclusion of regional climate fluctuations in the Red Sea sea level method. Our analysis comprehensively supports our earlier conclusions of large-amplitude sea level variations during MIS 3 with a timing that is strongly similar to Antarctic-style climate variations.

Annotated record of the detailed examination of Mn deposits from the R/V Argo ZETES Expedition in the Pacific Ocean

The cores and dredges described are taken during the R/V Argo ZETES Expedition from March until August 1966 by the Scripps Institute of Oceanography. A total of 53 cores and dredges were recovered and are available at Scripps Institute of Oceanography for sampling and study.

Chemical composition of manganese nodules and crusts from the Atlantic and Pacific oceans

The cores and dredges described are taken during the R/V New Horizon RISE III Expedition from April until May 1979 by the Scripps Institute of Oceanography. A total of 36 cores and dredges were recovered and are available at Scripps Institute of Oceanography for sampling and study. The goal of this expedition was to accomplish the field work of a combined field and laboratory study aimed at increasing the understanding of the origins and development of young oceanic volcanoes.
