TL;DR: Together, these resources provide a rigorous set of training tools in modern planktonic foraminiferal taxonomy and a means of rapidly generating assemblage data via machine learning in future studies for applications such as paleotemperature reconstruction.

TL;DR: In this paper, the authors use continuous proxy records to argue that an equivalent relationship has held throughout the last 800 kyr, that is, since before the first occurrence of Heinrich events (strictly defined).

TL;DR: In this article, the authors show that surface waters of the north-eastern Atlantic actually warmed across this interval (∼1.2 − 0.8 Ma), which they argue reflects an increase in the northeastward transport of heat and moisture via the North Atlantic Current (NAC) into the Nordic Seas (the Atlantic Inflow).
Assessment of bacterial dependence on marine primary production along a northern latitudinal gradient
Eric Fouilland,Emilie Le Floc'h,Debra Brennan,Elanor Bell,Elanor Bell,Sian Lordsmith,Sian Lordsmith,Sharon McNeill,Elaine Mitchell,Tim Brand,E. Elena Garcia-Martin,Raymond J.G. Leakey +11 more
TL;DR: It is reported that sea temperature may be a key factor (but not the only one) influencing the interaction between bacteria and primary production in North Atlantic and Arctic waters, suggesting that low primary production rates could not sustain bacterial carbon demand in the coldest Arctic waters.

Persistent influence of precession on northern ice sheet variability since the early Pleistocene
Stephen Barker,Aidan Starr,Jeroen van der Lubbe,Alice M. Doughty,Gregor Knorr,Stephen Conn,Sian Lordsmith,Lindsey Owen,Alexandra Nederbragt,Sidney R. Hemming,Ian P. Hall,Leah J. LeVay +11 more
TL;DR: Using a record of North Atlantic ice rafting spanning the past 1.7 million years, the authors found that the onset of ice rafts within a given glacial cycle consistently occurred during times of decreasing obliquity whereas mass ice wasting (ablation) events were consistently tied to minima in precession.
