The Mediterranean Sea and the Red Sea OHGDGT surface sediment data

We explore recently developed temperature proxies based on hydroxylated isoprenoid Glycerol Dialkyl Glycerol Tetraethers (OH-isoGDGTs), such as %OH, RI-OH, RI-OH' and TEX86OH for their potential for reconstructing temperature changes in the Mediterranean Sea and the Red Sea. These OH-isoGDGT-based proxies have not been adequately explored in these semi-enclosed basins. Here we explore the proxies derived from the OH-GDGTs from surface sediments from the Red Sea and Balearic Sea, and compile it with previously published data from the Gulf of Lions (Varma et al., 2023, doi:10.1016/j.gca.2023.12.019 (GCA)). The excel sheet contains information regarding the surface sediments, their location, enivironmental parameters from each location extracted from WOA and NISPP AVHRR database, peak area of iso-GDGTs and OH-isoGDGTs, proxy indices discussed in the study and references for previously published data.

本研究探讨了基于羟基异戊二烯甘油二烷基甘油四醚（OH-isoGDGTs）的新型温度代用指标，例如%OH、RI-OH、RI-OH'和TEX86OH，评估其在重建地中海和红海温度变化方面的潜力。此类基于OH-isoGDGTs的代用指标在这些半封闭的湖泊中尚未得到充分的探讨。在本研究中，我们分析了源自红海和巴利阿里海表层沉积物中的OH-GDGTs代用指标，并将其与之前在狮子湾（Varma等，2023，DOI：10.1016/j.gca.2023.12.019，GCA）发表的文献数据相结合。Excel表格包含了有关表层沉积物、其位置、来自WOA和NISPP AVHRR数据库的每个地点的环境参数、iso-GDGTs和OH-isoGDGTs的峰值面积、研究中讨论的代用指标索引以及已发表数据的参考文献。
