Palaeoenvironment, palaeoclimate and sea-level changes in the Shuaiba Lagoon during the late Holocene (last 3.6 ka), eastern Red Sea coast, Saudi Arabia

Abu-Zied, R. H. and Bantan, R. A.: Palaeoenvironment, palaeoclimate and sea-level changes in the Shuaiba Lagoon during the late Holocene (last 3.6 ka), eastern Red Sea coast, Saudi Arabia, The Holocene, 25(8), 1301–1312, doi:10.1177/0959683615584204, 2015.

"We used a Thermo Scientificdegrees Trace gas chromato graph equipped with an Rxi5ms column (30 m degrees 0.25 mm, film thickness 1 permilm) and a programmable temperature va porizing (PTV) injector operated in solvent split mode with an evaporation temperature of 60 permil C. The GC was con nected via a GC Isolink with pyrolysis/combustion furnace (at 1400/1000 permilC) and a Conflo IV interface to a DeltaVPlus isotope ratio mass spectrometer. The H+3 factor (Sessions et al., 2001) was determined daily to test measurement linearity of the system and accounted for 5.8 ppm mvpermil1 on average. Reference peaks of H2 bracket nalkanoic acid peaks during the course of a GCIRMS run; two of these peaks were used for the standardization of the isotopic analysis, while the remainders were treated as unknowns to assess pre cision. Except for the case of coelution, precision of these replicates was better than 0.6 permil."

Since temperature and precipitation amounts are anticor- related on an interannual timescale (Fig. 5), we interpret low ?D values to indicate both relatively cool and wet conditions. In addition to fluctuations in mean annual precipitation iso- topes, snowmelt and delivery to plants may vary. We suggest that a high proportional contribution of water derived from snowmelt, after relatively long and wet winters with high amounts of snowfall, can further lead to more negative ?D leaf wax values.
