TL;DR: A systematic delay between pronounced surface cooling and the arrival of ice-rafted debris at a site southwest of Iceland over the past four glacial cycles is demonstrated, implying that in general icebergs arrived too late to have triggered cooling, and is suggested thatrupt transitions to stadial conditions should be considered as a nonlinear response to more gradual cooling across the North Atlantic.

TL;DR: In this paper, the authors presented an almost 3 year long time series of shell fluxes and oxygen isotopes of left-coiling Neogloboquadrina pachyderma and Turborotalita quinqueloba from sediment traps moored in the deep central Irminger Sea.

TL;DR: A global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene, which can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, is presented.

TL;DR: The analysis indicates that the seasonality of planktonic Foraminifera shell flux is predictable and reveals the existence of distinct modes of phenology among species, and the effect of changing seasonality on paleoceanographic reconstructions is evaluated.

TL;DR: In this paper, the authors present a synthesis of living planktonic foraminifera abundance data in vertically resolved plankton net hauls taken in the eastern North Atlantic during 12 oceanographic campaigns between 1995 and 2012.
