Strontium to calcium ratio and oxygen isotopic coral records can exaggerate past decadal tropical climate variability - Communications Earth & Environment Strontium to calcium ratio and oxygen isotopic records from single corals contain a strongly autocorrelated non-climate noise component, which can inflate reconstructed temperature variability, according to analyses of coral records and sea surface temperature data.

The star on the map indicates the origin of the sample material. Based on their analyses, the researchers were able to demonstrate that there is a connection between the Southern Ocean and the Banda Sea (Indonesia). Graphic: Martina Hollstein

New #MARUM Publication: A research team investigated the hemispheric origin of the Indonesian Throughflow and found that it has been strongly influenced by the Southern Hemisphere over the past 800,000 years.
