Meridional reorganizations of marine and terrestrial productivity during Heinrich events
[1] To study the response of the global carbon cycle to a weakening of the Atlantic Meridional Overturning Circulation (AMOC), a series of freshwater perturbation experiments is conducted both under preindustrial and glacial conditions using the earth system model of intermediate complexity LOVECLIM. A shutdown of the AMOC leads to substantial cooling of the North Atlantic, a weak warming of th...
متن کاملLinks between ocean temperature and iceberg discharge during Heinrich events
Palaeoclimate records have revealed the presence of millennial-scale climate oscillations throughout the last glacial period1. Six periods of extreme cooling in the Northern Hemisphere—known as Heinrich events—were marked by an enhanced discharge of icebergs into the North Atlantic Ocean2,3, increasing the deposition of ice-rafted debris2. Increased sliding at the base of ice sheets as a result...
متن کاملJohann Heinrich Dierbach (1788–1845)
his eighties. In 1835, he married and settled in Paris as a teacher at the Conservatoire des Arts et Metiers, while conducting agricultural experiments with his brother-in-law on an estate in the Alsace, which was sustained economically by revenues from oil-bearing sands. Although McCosh's account of the collaboration with Dumas and the fat controversy with Liebig does not replace that given by...
متن کاملLink between the North and South Atlantic during the Heinrich events of the last glacial period
High resolution benthic oxygen isotope records combined with radiocarbon datings, from cores retrieved in the North, Equatorial, and South Atlantic are used to establish a reliable chronostratigraphy for the last 60 ky. This common temporal framework enables us to study the timing of the sub-Milankovitch climate variability in the entire surface Atlantic during this period, as re#ected in plank...
متن کاملSimulations of Heinrich Events in a coupled ocean-atmosphere-sea ice model
[1] Between 20 and 80 kyr ago several cooling cycles occurred in the Northern Hemisphere which culminated in a discharge of icebergs into the North Atlantic. These so called ‘‘Heinrich Events’’ (HEs) were followed by an abrupt shift to a warmer climate. Here we use a coupled ocean-atmosphere-sea ice model to study the response of the climate system under glacial conditions to a hypothetical HE....
