Abstract Recent chronostratigraphic evidence suggests that the central Australian Great Barrier Reef formed within the past 780 k.y. Periplatform sediments of the same age recovered from the western Coral Sea record a progressive decrease in the δ18O of planktonic foraminifera to the present. Several investigators have proposed that this trend represents an appreciable late Pleistocene warming (∼4 °C) of ocean surface temperatures, which they posit catalyzed the growth of the Great Barrier Reef. Contrary to this hypothesis, we demonstrate using alkenone paleothermometry (\batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(U_{37}^{k{^\prime}}\) \end{document}) on sediments from Ocean Drilling Program (ODP) Site 820 that sea-surface temperatures (SSTs) in the western Coral Sea changed by ∼1.5 °C or less during the past ∼800 k.y. If the central Great Barrier Reef rose in the late Quaternary, it was therefore not due to a warming of SSTs. We explore whether a major moisture balance change and/or diagenetic alteration of calcareous microfossils can explain the higher δ18O values observed at depth in the planktonic δ18O record at ODP Site 820. Our results suggest that diagenesis provides a large isotopic overprint.

A quantitative analysis of radiolarian species in 57 deep-sea surface sediment samples from the South Atlantic Ocean produced four geographically distinct assemblages (tropical, polar, gyre margin, and subtropical). The distributions of these assemblages or factors coincide with present-day patterns of sea-surface temperatures or water masses.These four assemblages were used to construct a transfer function relating radiolarian distribution in the surface sediments to present-day winter and summer temperatures using standard regression techniques. As a test of the quality of this transfer function, temperatures were estimated on surface sediment samples from the eastern South Pacific. The temperatures produced by the transfer function compared favorably with the observed (present-day) winter and summer sea-surface temperatures at these sites.

Lessepsian Species

This paper characterizes non-indigenous fish species (NIS) and analyses both atmospheric and sea surface temperatures for the Mediterranean coast of Egypt from 1991 to 2020, in relation to previous reports in the same areas. Taxonomical characterization depicts 47 NIS from the Suez Canal (Lessepsian/alien) and 5 from the Atlantic provenance. GenBank accession number of the NIS mitochondrial gene, cytochrome oxidase 1, reproductive and commercial biodata, and a schematic Inkscape drawing for the most harmful Lessepsian species were reported. For sea surface temperatures (SST), an increase of 1.2 °C to 1.6 °C was observed using GIS software. The lack of linear correlation between annual air temperature and annual SST at the same detection points (Pearson r) could suggest a difference in submarine currents, whereas the Pettitt homogeneity test highlights a temperature breakpoint in 2005–2006 that may have favoured the settlement of non-indigenous fauna in the coastal sites of Damiette, El Arish, El Hammam, Alexandria, El Alamain, and Mersa Matruh, while there seems to be a breakpoint present in 2001 for El Sallum. This assessment of climate trends is in good agreement with the previous sightings of non-native fish species. New insights into the assessment of Egyptian coastal climate change are discussed.
