About this Research Topic
Paleoceanographic reconstructions of past interglacial periods in high northern latitudes can provide useful insights and scenarios for future climate prediction. However, such reconstructions in subpolar and polar environments involve multiple challenges due to a strong influence of melt water, issues with quantifying the cold end of temperature calibrations, restricted species’ compositions in many biological groups, and more. Significant recent advances in developing new paleoceanographic methods (especially in the field of geochemistry and biogeochemistry) and elaborating existing methods allow for evaluation of past changes in seasonal sea-ice extent, salinity, and ocean circulation. Paleo-temperature estimations of surface, subsurface and bottom waters also have been considerably improved.
In this Research Topic, we welcome contributions exploring oceanic environments in high northern latitudes during the pronounced Quaternary interglacial periods, especially Marine Isotope Stages 11, 9, 5e, and 1, by means of various paleoceanographical methods, from paleontological to biogeochemical. Suborbital and millennial-scale reconstructions of oceanic conditions and circulation are especially encouraged.
