Renewal of deep water in the Red Sea during 1982–1987
Abstract
Between October 1982 and May 1983 the deep water in the northern Red Sea was ventilated through slope convection. The deep water became cooler, fresher, and more oxygenated. Dense bottom water formed in the Gulf of Suez during winter cooling sank down the continental slope, thereby entraining near‐surface and intermediate depth waters. From the application of a one‐dimensional plume model, a vertical transport of 0.58 × 10 6 m 3 s−1 over a period of 7 months was estimated. Long‐term time series of atmospheric heat fluxes show that such a major convection event can occur every 4–7 years. The corresponding renewal time of the Red Sea deep water is thus of the order of 40–90 years, in agreement with previous estimates.

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.
