Three hundred eighty thousand year long stable isotope and faunal records from the Red Sea: Influence of global sea level change on hydrography
Open accessAbstract
Stable isotope and faunal records from the central Red Sea show high‐amplitude oscillations for the past 380,000 years. Positive δ 18 O anomalies indicate periods of significant salt buildup during periods of lowered sea level when water mass exchange with the Arabian Sea was reduced due to a reduced geometry of the Bab el Mandeb Strait. Salinities as high as 53‰ and 55‰ are inferred from pteropod and benthic foraminifera δ 18 O, respectively, for the last glacial maximum. During this period all planktonic foraminifera vanished from this part of the Red Sea. Environmental conditions improved rapidly after 13 ka as salinities decreased due to rising sea level. The foraminiferal fauna started to reappear and was fully reestablished between 9 ka and 8 ka. Spectral analysis of the planktonic δ 18 O record documents highest variance in the orbital eccentricity, obliquity, and precession bands, indicating a dominant influence of climatically ‐ driven sea level change on environmental conditions in the Red Sea. Variance in the precession band is enhanced compared to the global mean marine climate record (SPECMAP), suggesting an additional influence of the Indian monsoon system on Red Sea climates.

During extreme low sea level stands in some parts of the Red Sea, salinities would have been high enough to prevent plankton growth and marine resources dependent on the plankton food chain.
“There is an added problem in some parts of the Red Sea that during extreme low sea level stands salinities would have been high enough to prevent plankton growth (Hemleben et al. 1996; Fenton et al. 2000) and marine resources dependent on the plankton food chain.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
